Image Builder (Gitlab CI/CD)

+

The image builder template builds the following images and pushes them to any +Docker registry:

+
    +
  • backend
    • +
  • frontend
    • +
  • documentation
    • +
  • guacamole
    • +
+

Please add the following section to your .gitlab-ci.yml:

+
include:
+  - remote: https://raw.githubusercontent.com/DSD-DBS/capella-collab-manager/${CAPELLA_COLLABORATION_MANAGER_REVISION}/ci-templates/gitlab/image-builder.yml
+
+

The build images are tagged with the revision they were build with (e.g., when +running for main the tag would be :main) All characters matching the regex +[^a-za-z0-9.] will be replaced with -.

+

You have to add the following environment variables on repository level. Make +sure to enable the "Expand variable reference" flag.

+
    +
  • PRIVATE_GPG_PATH: Path to the private GPG key used to decrypt the + secret.docker.json file (More about this file below)
    • +
  • Variables speciying how to name each image:
    • +
  • FRONTEND_IMAGE_NAME (defaults to capella/collab/frontend)
    • +
  • BACKEND_IMAGE_NAME (default to capella/collab/backend)
    • +
  • DOCS_IMAGE_NAME (defaults to capella/collab/docs)
    • +
  • GUACAMOLE_IMAGE_NAME (defaults to capella/collab/guacamole)
    • +
+

In addition you can adjust the following variables when running a pipeline:

+
    +
  • Variables specifying whether to build an image (default to 1):
    • +
  • FRONTEND: Build the frontend image?
    • +
  • BACKEND: Build the backend image?
    • +
  • DOCS: Build the docs image?
    • +
  • GUACAMOLE: Build the guacamole image?
    • +
  • TARGET: The target for which you want to build the images (More information + why this is important below)
    • +
+

This is the (minimal) configuration. For more advanced configuration options, +please refer to the +image-builder +Gitlab template.

+

Docker SOPS File

+

We make use of Mozilla SOPS files to store +secrets used in the image builder template. Therefore you need to have a +directory $TARGET for each target with a secret.docker.json inside. You can +create the secret.docker.json by running the following command:

+
sops -e --output ./<target>/secret.docker.json input.json
+
+

The input.json in this command is a placeholder for your own input file, +which should have the following structure:

+
{
+  "registry_unencrypted": "<registry>",
+  "username_unencrypted": "<username>",
+  "password": "<unencrypted password>"
+}
+
+

Verify that you can open the secret file with +sops ./<target>/secret.docker.json. When it works, delete the input.json!

+

In addition, you will need a .sops.yaml at the root level having the +following structure:

+
creation_rules:
+  - path_regex: .*
+    key_groups:
+      - pgp:
+          - <GPG fingerprint>
+
+

Any time you update the .sops.yaml (i.e., adding or removing a fingerprint) +you will have to run sops updatekeys ./<target>/secret.docker.json to ensure +that only authorized persons can decrypt the secret file.

+

Lastly, please ensure that your Gitlab runners GPG fingerprint is present in +the .sops.yaml such that it can use the secret values.

Kubernetes Deployment (Gitlab CI/CD)

+

The Kubernetes deploy template is used to deploy the Capella Collaboration +Manager to a Kubernetes cluster using Helm.

+

Please add the following section to your .gitlab-ci.yml:

+
include:
+  - remote: https://raw.githubusercontent.com/DSD-DBS/capella-collab-manager/${CAPELLA_COLLABORATION_MANAGER_REVISION}/ci-templates/gitlab/k8s-deploy.yml
+
+

You have to add the following environment variables on repository level. Make +sure to enable the "Expand variable reference" flag.

+
    +
  • PRIVATE_GPG_PATH: Path to the private GPG key used to decrypt the + secret.k8s.json files.
    • +
  • GRAFANA_HELM_CHART: (Optional) - This variable is used to set the URL for + the Grafana Helm chart. It is useful if your deployment environment has + limited access, so you can specify a URL that is accessible for you.
    • +
+

In addition you can adjust the following variables when running a pipeline:

+
    +
  • TARGET: The target for which you want to build the images (More information + why this is important below)
    • +
  • REVISION: The revision of the capella collab manager repository you want to + use
    • +
+

Docker and Kubernetes SOPS Files

+

For the k8s-deploy.yml you need to have some secret sops files in place. +First of all, you need a secret.docker.json file as described +here. In addition, you need to have a secret.k8s.json in +each target directory created by a json file having the following structure:

+
{
+  "server_unencrypted": "<k8s server>",
+  "namespace_unencrypted": "<namespace>",
+  "release_unencrypted": "<release>",
+  "username_unencrypted": "<username>",
+  "token": "<unencrypted token>"
+}
+
+

In addition, you need to have a general.values.yaml containing all the +values.yaml values that do not have to be encrypted and a +secret.values.yaml only containing the values that should be encrypted +(Please do not use YAML anchors in the secret.values.yaml file and do not use +the _unencrypted suffix in the variable names).

+

Please delete the plain text files containing secrets directly after encrypting +them.

+

Gitlab Repository Tree

+

The tree inside of your Gitlab repository should look like:

+
├── .gitlab-ci.yml
+├── .sops.yaml
+├── environment.prod.ts
+├── favicon.ico
+├── target1
+│   ├── general.values.yaml
+│   ├── secret.values.yaml

+│   ├── general.values.yaml
+│   ├── secret.values.yaml
+│   ├── secret.docker.json
+│   └── secret.k8s.json
+└── ...
+
+

This is the (minimal) configuration. For more advanced configuration options, +please refer to the +k8s-deploy +Gitlab template.

Command line tool

+ + + +

The Collaboration Manager repository contains a few tools that may come in +handy when you're an administrator of a Collaboration Manager setup.

+

The CLI (Command Line Interface) tool allows you to backup and restore user's +workspaces.

+

For the tools to work you'll need access to the Kubernetes cluster the +Collaboration manager is running on. In particular the namespace used to spawn +sessions.

+

Installation

+

In order to use the CLI tooling, you'll need to have a local copy of the +collab-manager application and Python 3.11 installed.

+
git clone https://github.com/DSD-DBS/capella-collab-manager.git
+cd capella-collab-manager/backend
+python -m venv .venv
+source .venv/bin/activate
+pip install .
+
+

Usage

+

Once your environment is set up, you can use the CLI tooling. The tooling is +located in a module:

+
python -m capellacollab.cli --help
+
+

This gives you the help information. The CLI tool currently has one subcommand: +ws, short for workspace.

+
Usage: python -m capellacollab.cli [OPTIONS] COMMAND [ARGS]...
+
+Options:
+  --install-completion [bash|zsh|fish|powershell|pwsh]
+                                  Install completion for the specified shell.
+  --show-completion [bash|zsh|fish|powershell|pwsh]
+                                  Show completion for the specified shell, to
+                                  copy it or customize the installation.
+  --help                          Show this message and exit.
+
+Commands:
+  ws
+
+

You can discover the CLI on your own by printing the help messages of the +subcommands

+
python -m capellacollab.cli ws --help
+python -m capellacollab.cli ws backup --help

Getting Started

+

This guide describes the steps to get started with the Capella Collaboration +Manager.

+

Before you start, make sure you have a running environment. For instructions on +how to set up such an environment, please refer to the +Development installation guide.

+

First open a browser and go to http://localhost:8080.

+

You will be welcomed by a friendly screen and you can log in. The default setup +is running an OAuth mock service for authentication.

+

Welcome screen

+

As username, provide the admin for the admin user. If you have changed the +username or want to test another user, enter your custom username.

+

OAuth mock

+

You'll be returned to the Collaboration manager. Now you can start a session. +Select Persistent Workspace and hit Request Session.

+

Logged in

+

The system will now schedule and start a fresh workspace. Wait a bit for the +workspace to be available

+

Starting a session

+

Once the session is ready, click Connect to Session and a new tab should +open. After a few seconds you should see the Capella splash screen and a +workspace will be shown in your browser.

+

Capella welcome screen

+

What's Next

Installation of the Collaboration Manager

+

This guide will help you set up the Capella Collaboration Manager on a +Kubernetes cluster. The setup of the basic installation is straightforward, but +we'll also delve into the more complex TeamForCapella support that requires +building custom Docker images.

+

During development, we also took into account that the application can be +installed in highly restricted environments. An internet connection is not +necessarily required.

+

Step 1: Set up a Kubernetes Cluster

+

Kubernetes allows us to make operations as simple as possible later on. Updates +can be fully automated. In addition, Kubernetes allows us to ensure a secure +operation through standardized security hardening.

+

You can use an existing cloud service to create a Kubernetes cluster. We have +running production deployments on Microsoft AKS and Amazon EKS. The application +is designed in such a way that no cluster scope is necessary. All operations +run at the namespace level, so it even runs in shared OpenShift clusters. But +also if you simply have a Linux server at your disposal, this is no obstacle.

+

If you already have a running cluster, have kubectl up and running and can +reach the cluster, then you can skip this step.

+

We provide instructions for some environments. If you set up the application in +a different environment, please document the installation and obstacles that +you find and we would be happy to receive a PR to help other users in the +future.

+
+
+
+
+

Info

+

We have tested the instructions with Ubuntu Server 22.04.

+
+
    +
  1. +

    Run steps 1-4 of the official microK8s Getting started guide.

    +
    2. +
  2. +

    Enable all required add-ons: + 

    microk8s enable hostpath-storage # For persistent storage
+microk8s enable rbac # For role-based access control
+microk8s enable ingress # For load balancing
+

    +
    3. +
  3. If you don't have any external registry available and TeamForCapella support is required, enable the registry: + 
    microk8s enable registry
+export DOCKER_REGISTRY=localhost:32000
+
    4. +
  4. Copy the kubectl configuration to the host, so that helm can pick it up: + 
    mkdir -p $HOME/.kube
+microk8s config > $HOME/.kube/config
+chmod 600 $HOME/.kube/config # Nobody else should be able to read the configuration
+
    5. +
  5. +

    Optional, but recommended: Set up a NFS for workspaces and Juypter file-shares. + The default hostpath-storage of microK8S doesn't enforce the specified capacity on PVCs. + This can be exploited by a user uploading so much data to their workspace that + the server goes out of disk storage.

    +

    Please follow the official instructions: https://microk8s.io/docs/nfs.

    +

    Make sure to update the backend.storageClassName in the values.yaml in step 6 to nfs-csi. +All new Jupyter file-shares and personal workspaces will use the new storage class then.

    +
    +

    User mapping for non-root containers

    +

    If you want to run the session containers as non-root, you can set the runAsUser value in the podSecurityContext of the values.yaml. +In the default configuration, runAsUser is set to 1004370000.

    +

    Unfortunately our setup NFS does not respect the fsGroup option. Therefore, all volumes are mounted with nobody:nogroup per default. +This will lead to permission errors and crashing session containers.

    +

    To fix it, change the /etc/exports file and modify the options for the create file-share to: +

    (rw,sync,no_subtree_check,all_squash,anonuid=<user-id-of-session-containers>,anongid=0)
+

    +

    Replace <user-id-of-session-containers> with the value of the runAsUser value of the Kubernetes Pod security context.

    +

    Then, apply the new configuration by running exportfs -ra.

    +
    +

+
+
+
+

Step 2: Validate the Available Resources

+

The minimum required resources are 3 +Kubernetes CPU cores +and around 2,5GiB of memory for the management platform. Depending on the load, +the instance can scale up and is limited to 10 Kubernetes CPU cores cores and +~8GiB of memory.

+

Each session requires a minimum of 0.4 Kubernetes CPU cores and 1.6Gi of +memory. A session can scale up until it reaches 2 Kubernetes CPU cores and 6Gi +of memory.

+

Step 3: Set up the Required Namespaces (Optional)

+

The Collaboration Manager requires two different namespaces. For security and +overview reasons, they are separated:

+ +
    +
  • +

    Capella Collaboration Manager control namespace: In this namespace, we run + the core application. It has full control over the sessions namespace and consists of the following services:

    +
      +
    • Frontend
      • +
    • Backend
      • +
    • Documentation
      • +
    • Guacamole
      • +
    • Prometheus
      • +
    • Grafana (Loki), can be disabled in the values.yaml
      • +
    +

    Sessions namespace. The namespace is controlled by the control namespace and you won't need to touch it. In the session namespace, the following services run:

    +
      +
    • Storage for persistent workspaces
      • +
    • Storage for Juypter file-shares
      • +
    • Pipeline jobs for nightly TeamForCapella to Git synchronisation
      • +
    • Session containers (Capella, Papyrus, Juypter, pure::variants)
      • +
    +
    • +
+ +
    +
  1. +

    Create the two required namespaces:

    +
    kubectl create namespace collab-manager # If you use another name, please update the following commands and use your namespace name.
+kubectl create namespace collab-sessions # If you use another name, please update the `values.yaml` accordingly.
+
    +
    2. +
  2. +

    Set the collab-manager as default namespace in the default context (optional):

    +
    kubectl config set-context --current --namespace=collab-manager
+
    +
    3. +
+

Step 4: Install helm

+

Follow the official instructions to install Helm: +Installing helm

+

Verify that helm is working by executing the command:

+
helm version
+
+

Step 5: Clone the Github Repository

+

Navigate to a persistent location on your server, e.g. /opt. Then clone the +Github repository by running:

+
git clone https://github.com/DSD-DBS/capella-collab-manager.git
+
+

Step 6: Configure the Environment / Create the values.yaml

+

Copy the +values.yaml +to a persistent and secure location on your server or deployment environment. +The local directory in the Collaboration Manager is gitignored. We recommend +to put the custom values.yaml in this directory.

+

Make sure to set restrictive permissions on the values.yaml:

+
chmod 600 values.yaml
+
+

Adjust all values according to your needs.

+

Step 7: Install the Application in the Cluster

+

Run the following commands in the root directory of the repository:

+
helm dependency update ./helm
+helm upgrade --install \
+    --namespace collab-manager \
+    --values <path-to-your-custom-values.yaml> \
+    <release-name> \
+    ./helm
+
+

Step 8: Initialize the Guacamole Database

+

The Guacamole database is not initialized automatically. Run the following +command to initialize the PostgreSQL database:

+
kubectl exec --container <release-name>-guacamole-guacamole deployment/<release-name>-guacamole-guacamole -- /opt/guacamole/bin/initdb.sh --postgresql | \
+    kubectl exec -i deployment/<release-name>-guacamole-postgres -- psql -U guacamole guacamole
+
+

After the initialization, the Guacamole password defaults to guacadmin. We +have to change it to a more secure password:

+
    +
  1. Open http://localhost:8080/guacamole/ and login with guacadmin / + guacadmin.
    2. +
  2. Click on the guacadmin user at the top-right corner of the screen, then + select "Settings".
    3. +
  3. Select the tab "Preferences"
    4. +
  4. In the "Change password" section, enter guacadmin as current password. + Generate a secure password and enter it for "New password" and confirm it. + Then, click "Update password"
    5. +
  5. Log out and verify that the combination guacadmin / guacadmin no longer + works.
    6. +
  6. Update the key guacamole.password in the values.yaml and repeat step 7.
    7. +
+

Step 9: Check the Application Status

+

Run kubectl get pods to see the status of all components. Once all containers +are running, verify the installation state by running:

+
curl http://localhost/api/v1/health/general
+
+

It should return the following JSON:

+
{ "guacamole": true, "database": true, "operator": true }
+
+

If a value is false, check the backend logs for more information.

+

Step 10: Add TeamForCapella Support

+ +
+

TeamForCapella server required

+

The setup of the TeamForCapella server and license server itself will +not be part of this tutorial. To process, you'll need to have a running and +reachable TeamForCapella server.

+
+ +
+

Container registry required

+

For the TeamForCapella support, you'll need to build own Docker images. In order to use this in the cluster, an external or internal container registry is required.

+
+ +
    +
  1. Install GNU make >= + 3.82
    2. +
  2. Navigate to the root of the capella-collab-manager repository.
    3. +
  3. Clone the capella-dockerimages repository: + 
    git clone https://github.com/DSD-DBS/capella-dockerimages
+
    4. +
  4. +

    Prepare the capella/base and t4c/client/base images according to the + Capella Docker images documentation (Only the preparation section is + needed):

    + +
    5. +
  5. +

    Set the following environment variables:

    +
    export PUSH_IMAGES=1 # Auto-push images to the container registry after build
+export DOCKER_REGISTRY=<your-registry> # Location of your remote or local container registry
+export CAPELLA_BUILD_TYPE=offline # Don't download Capella during each build
+export CAPELLA_VERSIONS="5.2.0 6.0.0 6.1.0" # Space separated list of Capella versions to build
+export CAPELLA_DROPINS="" # Command separated list of dropins
+
    +
    6. +
  6. +

    Then, build the t4c/client/remote images (the one that we'll use in the + Collaboration Manager):

    +
    make t4c/client/remote
+
    +
    7. +
  7. +

    In the Collaboration Manager UI, change the docker image of the tool to + <registry>/t4c/client/remote:<capella-version>-latest

    +
    8. +

Uninstallation of the Collaboration Manager

+

We're sorry to see you go 😭
If you have any suggestions for us to +improve, please share them with us. Either privately via set@deutschebahn.com +or via a +Github issue.

+ +
    +
  1. +

    If you want to uninstall the management portal, you can run the following + comment:

    +
    helm uninstall <release-name> -n <namespace> helm
+
    +

    or delete the management portal namespace:

    +
    kubectl delete namespace <namespace>
+
    +
    2. +
  2. +

    The previous command doesn't clean the sessions namespace. Please clean it + manually by running (this does also remove all persistent workspaces!):

    +
    kubectl -n <sessions-namespace> delete all --all
+
    +

    or just delete the namespace:

    +
    kubectl delete namespace <sessions-namespace>
+

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.

GitTeamForCapella
Multiple workstreamsDifferent workstreams available via branchesNot recommended, only possible via different repositories
Concurrent workingVery challenging because of merge conflict potential.Is possible. Diagrams are locked, no risk of merge conflicts.
Merge conflictsResolution of merge conflicts can be challenging.No merge conflicts when one workstream is used. For multiple workstreams, the resolution of merge conflicts can be challenging.
LicenseNo license needed1TeamForCapella license required2
ComplexityGit knowledge is required3Easy to use
StabilityVery stable solution as changes are initially saved locally. Temporary server downtimes can also be bridged.Changes may be lost if the server becomes unavailable during work.
Potential of data lossChanges are backed up after each push (more regularly).Changes are backed up on a nightly basis.
AutomationPossible via CI/CD in the Git repository.Possible via TeamForCapella → Git synchronisation (runs on a nightly basis).
Change controlReviews are possible via merge requests4Change control is nearly impossible, no barriers.
Release taggingDirectly possible via tags in Git.Possible via TeamForCapella → Git synchronisation (Releases are stored as tags in the Git repository).

Some General Words

+ + +
    +
  • Git-only - the modeling team uses a git repository to work on the model. + The team may use git branches to work on features or capabilities in parallel + and a main branch is used for integration and release-tagging. This way of + working gives the modeling leads / change control board great control over + what contents make it to the model that is used for releases (of things like + design documentation). On the downside this co-working method is fairly + complicated and requires skilled modeling leadership for challenges like + merge conflict resolution and fragmentation management (a way to break up + model into smaller files to reduce density of merge conflicts).
    • +
  • +

    Git + TeamForCapella - with this approach the modeling team can co-work + with a very high degree of concurrency and stay away from the difficulties of + merge conflict resolution. On the downside it is much harder to control what + makes it into the model as there is no barrier except for maybe a modeling + process that would stop a person from making changes that are not allowed. + Yet there are a few ways around that limitation. For teams with basic or no + experience in modeling and git this is probably the best way to start + co-woking. Git is still used for nightly backup of the model and + release-tagging.

    +
    +

    Info: TeamForCapella license required

    +

    For this co-working method to be enabled you need a valid +TeamForCapella license and TeamForCapella server installed and +integrated with Collab-Manager.

Working with Git

+

In this guide we explain how to use Git via Eclipse. When using Git we make +changes locally and push them to a remote (Gitlab or Github mainly) +repository. Here we explain how to get made changes to the remote repository so +that collegues can see and review them.

+

Clone a Repository

+

First open the View Git Repository by clicking on the magnifying glass (1) in +the right corner.

+

Step 1: Open View Search

+

Searching looks like:

+

Step 2: Search for View

+

When clicking "Clone a Git repository" a view "Source Git Repository" to enter +the repository url opens. Enter here the URL of the Remote of your repository +and if it is not a public repository enter your username and password. After +clicking "Next" the "Branch Selection" opens. Here you can pick a branch on +which you want to work. After clicking "Next" another time, the view "Local +Destination" opens. This shows where your work is going to be stored locally.

+ +
+

Info

+

Tick the box: "Import all existing Eclipse projects after clone +finishes" importing the cloned repository into your eclipse workspace

+
+

Step 3: Local Destination

+

Then you can click finish. Your repository from the Remote is now cloned +locally.

+

Switch Branches

+

To collaborate it might be useful to work on different branches. Therefore, +there are two ways to switch branches (to checkout existing ones or to create a +new one).

+

Either you right click on the project name in the lower right corner, go to +"Switch to" and then e.g. "New Branch"

+

Step 4: Search for View

+

or you can right click on the project name in the project tree and then click +"Team"> "Switch to" > "New Branch".

+

Step 5: Search for View

+

In order to make the changes visible in your project tree and to see on which +branch you are currently working on right click on the project name > "Close +Project" and then open the project again.

+

Prepare to Commit - Stage Changes

+

In Git staged changes are saved changes that we mark to use in our next commit.

+

In order to stage changes in Eclipse, open the View: Git Staging. In that +view you can see the staged and the unstaged changes (1). You can also see +changes that you made in the file tree on the left indicated by ">" (2). If +there are no (un-)staged changes you did not make a change compared to the last +state that Git already has saved in commits.

+

Step 6: Search for View

+

In the Git Staging View mark the unstaged files that you want to stage and +drag them with your mouse to the "Staged Changes" area. Then reload (3) the +View in order to see the made changes.

+

Commit and Push Changes

+

After having staged the changes they should be put into a commit. Therefore, +type a commit message to show what changes have been made. A commit message can +look like:

+
Short summary of the changes
+
+Details of the made changes
+Change #1
+Change #2
+
+

Thus you and your collegues know what happened in the commit. Then commit the +changes (2).

+ +
+

Info

+

The commit is now made locally. In order to publish it and share it with other you have to push it to the Remote!

+
+

Step 7: Search for View

+

If you already committed your changes you can right click on the Project > +"Team" > "Push to Origin" in order to push your changes to the remote.

+

If you have not commited yet and want to publish your changes and to share them +with your team rather click: "Commit and Push" (1). If you have not configured +that before you are now asked to "Configure upstream for push and pull" and the +selected default of "Merge" can just be kept. You might now be asked to enter a +user and a password for the remote repository in order to push your changes +there. Having done that you can click "Push".

+

Now your changes are saved at the remote repository where they are not lost and +your collegues can see them.

+

Diff and Merge Models

+ +
+

Warning

+

If you have to merge due to a merge conflict do not commit unless all conflicts highlighted are solved.

+
+

If the merge tool is not opening on its own due to a merge conflict you can +also diff two models on your own in order to check which changes were made.

+

Therefore, select both .aird-files (e.g. with control click). Then right +click on one of the files and select "Compare with" > "Each other as model".

+

Open compare View

+

In the image you can see the +coffee machine model imported +twice with different changes made to each model in order to compare them.

+

In the View "Define the comparison operation to perform" it is important to +choose the correct order of which model is the source and which one is the +target. In that case we are taking the changes in the source to apply them to +the target, and are going to change the target model.

+ +
+

Warning

+

Make sure to select the correct direction of merging in order to modify the +correct model.

+
+

Configure Merge Direction

+

In the example we want to merge our changes from Left (coffee-machine model on +working branch) into Right (coffee machine model on main branch)(1).

+

Afterwards click "Configure" (2) to make further configurations.

+

Choose the option "Transfer of elements between models created independently". +Then click "Show advanced settings >>" to configure the matching process +between elements. Thus, click the now appeared tab "Matching".

+

Usually the UUIDs of the objects in your model should be stable. So ticking the +Absolute criteria "Technical IDs" and "Property IDs" should be sufficient. +Especially for if you know that there could be changes in diagrams you might +also want to tick "Diagrams: Match shapes according to represented elements" +and "Diagrams: Match remaining shapes according to type" as in Diagrams IDs +might change just by opening them. If nothing else helps choose "Names" and +click "Use labels as names" to match but labels easily change.

+

Configure Matching Strategie

+

Afterwards, click "Ok" and "Finish".

+

Then you get into the merge view. Marked with the lock you can see which model +is going to be modified. They are also labeled as source and target where the +source is from which we are taking the changes and the target is the model that +gets modified.

+

Explain Merge View

+

The colors highlight what change was made and will be applied to the target if +you apply the change: blue: create, red: delete, purple: modify.

+

If there are any objects that are overarching you have to merge them seperately +as they can not be merged in the seperate layers.

+

Merge Model Elements

+

In the synthesis view you can see the number of changes that happened. If you +click on a specific change you can see in the Details (1) and also marked in +blue on both models what changed and possibly how the current status in both +models is. Then you can right click on the change in the synthesis view and +click "Apply change(s)" (2) and you can click "Ok" then. Afterwards make sure +to Ctrl+S or File > Save to save the change made.

+ +
+

Warning

+

If any of your changes depend on common objects independent of layers make sure +to also apply those changes in order to create a working modification of the +model.

+
+

If you have also changes in diagrams you should migrate them as well in the +same session.

+

Merge Diagrams

+

Diagrams are stored in the .aird file. There the application of changes +happens similar. You can have a look into the multiple stages to see the what +exactly changed in the diagrams and you can very detailed choose the changes +that you want to apply.

+

If you have also changes in the model content you should merge both in the same +session.

+

Merge Conflicts

+

Commit your changes as described above. Pull from the remote (e.g. right click +on the project > "Team" > "Pull"). This might result in merge conflicts which +you can solve via the merge tool.

+

Merging with the Merge Tool

+

In the above description we made sure to decide which model is our target and +is going to be modified while the changes would be taken from the source model. +In the case of a merge conflict we have changes in both models at the same +position and it is not possible to automatically decide which change to keep +and which to overwrite because possibly both are reasonable changes. Thus you +as a user have to decide which changes to keep. In the following we are +describing how you can pick the changes that you later want to see in the +model.

+

Decide Side of Change

+

With the butttons above the details of the made changes enable us to decide the +change from which model to take and which change to discard.

+

If the number of changes is overwhelming you can filter them by different +criteria (2). In the category "Three-way" you can tick "filtered" for the +changes that for the moment you prefer not to see and to tackle to apply the +changes one after another.

+

Make sure to resolve all conflicts before commiting! After merging reopen the +model and look especially into layouting as capella might be a bit +opportunistic in merging layouts.

+

Merging if Merge Tool is not Possible

+

If merging with the merge tool is not possible you have to open the reset view.

+

Step 8: Open Reset View

+

Then select hard reset of your local branch:

+

Step 9: Git Reset Hard

+

If you committed your changes earlier, and select your local main branch as +described, your local files will be reset to the state they were in after your +last local commit. This way, you drop the changes from the server locally, +but keep your changes. Removing the changes from the server in your local main +branch is not a problem, because they are still present in the remote main +branch on the git server.

+

You should now be able to see the project again with all changes, you +performed. Now you should push your local changes to a new branch. To do so, +right click on the project > "Team" > "Push branch 'main'...". In the view +"Push to branch in remote" you should enter an intermediate branch name like +“merge-branch-name” (1) and remove the “configure upstream push and pull” (2) +option.

+

Step 10: Git Create Intermediate Branch

+

After pushing your changes to the remote Git repository, open the remote +project on Gitlab or Github. Then open a Merge request (Gitlab) or Pull request +(Github) respectively and try merging your "merge-branch-name" branch into main +(or the branch you wanted to push on before).

+

You will now see whether the Merge request/ Pull request can be merged +automatically or not:

+ +
    +
  1. It can be merged automatically: Go for it and merge it. To continue working + on the model, we recommend using a new clean session of Capella.
    2. +
  2. It can’t be merged automatically: You have now two options:
      +
    1. Redo your work. We recommend using a new session for that.
      2. +
    2. Open a service request or contact the operations team in order to try to + get your changes merged manually.
      3. +
    +
    3. +
+

In order to publish your changes and to share them with your team click: +"Commit and Push" (1). If you have not configured that before you are now asked +to "Configure upstream for push and pull" and the selected default of "Merge" +can just be kept. You might now be asked to enter a user and a password for the +remote repository in order to push your changes there. Having done that you can +click "Push".

+

Now your changes are saved at the remote repository where they are not lost and +your collegues can see them.
