Docker Compose project for creating and managing an Islandora 8 instance using Docker containers from Docker Hub that were created by isle-buildkit.
In a nutshell, isle-dc generates a docker-compose.yml file for you based on configuration
that you supply in a .env file. And there are three use cases we're trying to accomplish:
- demo (Example site for kicking the tires and looking at Islandora)
- local (Local development using composer/drush in the codebase folder)
- custom (A custom Dockerfile to deploy created from local)
On top of that, there's a lot of useful commands for managing an Islandora instance, such as database import/export and reindexing.
- Desktop / laptop / VM (Docker must have sufficient resources to run GNU Make)
- Docker-CE 19.x+
- Docker-compose version 1.25.x+
- Git 2.0+
- GNU Make 4.0+
- At least 8GB of RAM (ideally 16GB)
before running any of the make commands below.
See release notes at https://docs.docker.com/compose/cli-command/.
To get started with a demo environment, run:
make demoOr if this demo environment is too simple, run make demo to create a demo site that is modeled after https://sandbox.islandora.ca with some extra content imported via Islandora Workbench.
make up\demo\local\clean for password, use your computer's password. The build process may need elevated privileges to write or remove files. For other password information see Secrets
This will pull down images from Dockerhub and generate
| File | Purpose |
|---|---|
.env |
A configuration file that is yours to customize. This file controls how the docker-compose.yml file gets generated to meet your use case. It also allows you to set variables that make their way into the final docker-compose.yml file, such as your site's domain. |
docker-compose.yml |
A ready to run docker-compose.yml file based on your .env file. This file is considered disposable. When you change your .env file, you will generate a new one. |
Your new Islandora instance will be available at
https://islandora.traefik.me. Don't let the
funny URL fool you, it's a dummy domain that resolves to 127.0.0.1.
If you do not have secrets enabled, you can log into Drupal as
admin using the default password: password. Otherwise you can find the
password in the file
./secrets/live/DRUPAL_DEFAULT_ACCOUNT_PASSWORD.
Enjoy your Islandora instance! Check out the Islandora documentation to see all the things you can do. If you want to poke around, here's all the services that are available to visit:

When you're done with your demo environment, shut it down by running
docker-compose downThis will keep your data around until the next time you start your instance. If you want to completely destroy the repository and all ingested data, use
docker-compose down -v
# OR a better option because it removes these directories (codebase/ certs/ secrets/live/) and
# resets all files back to their original states. This takes it back to a clean slate.
make clean
When developing locally, your Drupal site resides in the codebase folder and is bind-mounted into your
Drupal container. This lets you update code using the IDE of your choice on your host machine, and the
changes are automatically reflected on the Drupal container. Simply place any exported Drupal site as
the codebase folder in isle-dc and you're good to go.
If you don't provide a codebase, you'll be given a basic setup from vanilla Drupal 9 instance with the Islandora module
installed and the bare minimum configured to run. This is useful if you want to build your repository
from scratch and avoid islandora_defaults.
If you've included configuration in your exported site using drush config:export, then you'll need
to set two values in your .env file:
INSTALL_EXISTING_CONFIG=true
DRUPAL_INSTALL_PROFILE=minimal
In either case, run one of these commands to make a local environment.
make localThe former will create a starter site modeled off of https://sandbox.islandora.ca.
If you already have a Drupal site but don't know how to export it, log into your server, navigate to the Drupal root, and run the following commands:
drush config:exportgit initgit add -A .git commit -m "First export of site"
Then you can git push your site to Github and git clone it down whenever you want.
This environment is used to run your custom drupal image which can be produced
outside of this repository. You can specify the image in your .env file using
the settings PROJECT_DRUPAL_DOCKERFILE if you want to build it in the context
of this repository. You can also set the memory limits for each containers here as well.
For convenience a sample.Dockerfile is provided from which you can generate a
custom image from the codebase folder. For example if you followed
the guide above to create the codebase folder from the islandora/demo image.
And then run it by changing ENVIRONMENT to be custom and regenerating the
docker-compose.yml file and building the image.
make docker-compose.yml
make buildAt this point you could run it using docker-compose:
docker-compose up -dTo specify an image created outside of this repository, you can add the
following to docker-compose.env.yml:
drupal:
image: YOUR_CUSTOM_IMAGETo run a non-destructive shutdown and bring it back up without having to know the docker commands needed. This keeps all of the commands for basic operations within the make commands.
# Shut down isle-dc with losing work.
make down
# Bring isle-dc back up from where it left off
make up
# If make hasn't been run this will run make demo
When running Islandora in the wild, you'll want to use secrets to store sensitive information such as credentials. Secrets are communicated from the docker host to the individual containers over an encrypted channel, making it much safer to run in production.
Some confd backends, such as etcd, can be used to serve secrets directly.
Simply expose etcd over https and nothing else needs to be done. But for
other backends, particularly environment variables, you must mount the secrets
into containers as files using docker-compose. During startup, the files'
contents are read into the container environment and made available to confd.
To enable using secrets prior to running the make commands, copy sample.env
to .env. Set USE_SECRETS=true in your .env file. Make a copy of the files in
/secrets/template/ to /secrets/live/.
To enable using secrets after run make local or make up, set
USE_SECRETS=true in your .env file. When you run make docker-compose.yml, a
large block of secrets will be added at the top of your docker-compose.yml
file.
secrets:
ACTIVEMQ_PASSWORD:
file: "./secrets/live/ACTIVEMQ_PASSWORD"
ACTIVEMQ_WEB_ADMIN_PASSWORD:
file: "./secrets/live/ACTIVEMQ_WEB_ADMIN_PASSWORD"
...Each secret references a file in the secrets/live directory. These files are
generated by make. Each secrets file is named the exact same as the
environment variable it intends to replace. The contents of each file will be
used as the value for the secret.
To automatically run secret generator without prompting (for creating a CICD/sandbox process) use:
bash scripts/check-secrets.sh yesRun make set_admin_password and it will prompt the user to enter in a new password. Enter it in and the password for the "admin" user will be set to the new password.
$ make set_admin_password
Password: ***
Setting admin password now
[success] Changed password for admin.
Islandora is composed of many different services, this project has split these services up such that they have their own Container.
For in-depth documentation of the various islandora images see the
isle-buildkit repository.
Other services will be documented below:
The code-server container allows a user to edit / debug their Drupal site from their browser.
The code-server service can be disabled/enabled via the
INCLUDE_CODE_SERVER_SERVICE variable in your .env file.
# Includes `code-server` as a service.
INCLUDE_CODE_SERVER_SERVICE=true- Run
make local,make up, ormake demoto build the containers and local file system(s). - Then modify the
.envfile. - Then
make pullthenmake upto fetch the builds. It will then report it created the code-server and recreated traefik and drupal containers.
By default this will accessible at https://islandora.traefik.me:8443/.
If you do not have secrets enabled, you can login with the default
password: password. Otherwise you can find the password in the file
./secrets/live/CODE_SERVER_PASSWORD.
N.B: Do not expose this service on the internet without setting a strong
password via the ./secrets/live/CODE_SERVER_PASSWORD, or better yet do not
expose it at all, and instead use port forward to access it if you have the
need. Exposing this service in an insecure way will allow root access to your
server to the public.
To enable xdebug for your request, you must also send an XDEBUG_SESSION cookie
with your request, this can be toggled on and off via a browser plugin such as
the following.
The watchtower container monitors the running Docker containers and watches for changes to the images that those containers were originally started from. If watchtower detects that an image has changed, it will automatically restart the container using the new image. This allows for automatic deployment, and overall faster development time.
Note however Watchtower will not restart stopped container or containers that
exited due to error. To ensure a container is always running, unless explicitly
stopped, add restart: unless-stopped property to the container in the
[docker-compose.yml] file. For example:
mariadb:
image: islandora/mariadb:latest
restart: unless-stoppedThe watchtower can be disabled/enabled via the INCLUDE_WATCHTOWER_SERVICE
variable in your .env file.
# Includes `watchtower` as a service.
INCLUDE_WATCHTOWER_SERVICE=trueThe traefik container acts as a reverse proxy,
and exposes some containers through port 80/443/3306.
Since Drupal passes links to itself in the messages it passes to the microservices, and occasionally other URLs need to be resolved on containers that do not have external access, we define aliases for most services on the internal network.
Aliases like so are defined on most services to mimic their routing rules in Traefik:
drupal:
image: islandora/demo:latest
# ...
networks:
default:
aliases:
- islandora-isle-dc.traefik.meThe traefik service can be disabled/enabled via the INCLUDE_TRAEFIK_SERVICE
variable in your .env file.
# Includes `traefik` as a service.
INCLUDE_TRAEFIK_SERVICE=trueThe etcd container is a distributed reliable key-value store, which this project can use for configuration settings and secrets.
It is not enabled by default.
# Includes `etcd` as a service.
INCLUDE_ETCD_SERVICE=falseTo add custom Makefile commands without adding upstream git conflict complexity, just create a new custom.Makefile and the Makefile will automatically include it. This can be a completely empty file that needs no header information. Just add a function in the following format.
.PHONY: lowercasename
.SILENT: lowercasename
## This is the help description that comes up when using the 'make help` command. This needs to be placed with 2 # characters, after .PHONY & .SILENT but before the function call. And only take up a single line.
lowercasename:
echo "first line in command needs to be indented. There are exceptions to this, review functions in the Makefile for examples of these exceptions."NOTE: A target you add in the custom.Makefile will not override an existing target with the same label in this repository's defautl Makefile.
Running the new custom.Makefile commands are exactly the same as running any other Makefile command. Just run make and the function's name.
