jsctl

Note: currently this code can only be built and tested by those with access to Jetstack private repos. The process for community involvement has yet to be determined.

jsctl is the command-line tool for interacting with the Jetstack Secure Control Plane.

It can be used to configure a Kubernetes cluster with Jetstack Secure components and to create resources in Jetstack Secure control plane.

See jsctl reference documentation for all available commands or keep reading for common usage scenarios.

Getting Started

Obtain a binary for your os and architecture from the releases page and place it somewhere within your PATH environment variable.

Some commands make modifications to the Kubernetes cluster specified as your current context within your kubeconfig file. Ensure you're set up to use the correct cluster using the kubectl config use-context command. By default, the kubeconfig is expected at ~/.kube/config but it can be set via the KUBECONFIG environment variable or by providing the path via the --kubeconfig flag for commands that interact with clusters.

Authentication

To authenticate, use the jsctl auth login command. It will open your default browser and navigate to the login screen.

In a non-interactive environment, or if the browser cannot be opened, it will print out a URL for you to visit:

jsctl auth login
> Navigate to the URL below to login:
> https://auth.jetstack.io/authorize

Once you have logged in, you should see a Login Succeeded message in your terminal. Check the browser window for any errors.

To remove all authentication data from the host system, use the jsctl auth logout command.

Unattended

If you need to log in using a non-interactive environment, you can use service account credentials instead. Either set the location of the credentials as the JSCTL_CREDENTIALS environment variable or provide the location via the --credentials flag when calling jsctl auth login.

jsctl auth login --credentials /path/to/credentials.json

Configure organization

Once authenticated, select your organization using the jsctl config set command. The organization you select will be used for subsequent commands

jsctl config set organization my-organization
> Your organization has been changed to my-organization

You can view which organizations you belong to using the jsctl organizations list command.

Clusters

Connect Clusters

Once you've selected an organization, you can install the agent using the jsctl clusters connect command. This command applies the YAML required to install an agent in your cluster. This uses your current kubernetes context as the target for the deployment.

jsctl clusters connect my-cluster

Otherwise, you can write the output to a file and use it in your GitOps workflow:

jsctl clusters connect --stdout my-cluster >> agent.yaml

See jsctl reference documentation for additional cluster management options.

Operator

Jetstack Secure Operator can be used to set up a cluster with Jetstack Secure components, see documentation.

jsctl has a number of commands to make it easier to install and configure the operator, see reference documentation.

Install the Operator

To install the Jetstack Operator, you can use the jsctl operator deploy command. It will apply the manifests required to run the operator directly to your current kubernetes context. You will need to have obtained your secret key file for authenticating with the Jetstack container registry and provide it to the command via the --credentials flag.

jsctl operator deploy --credentials /path/to/secret.json

To just obtain the manifests, provide the --stdout flag:

jsctl operator deploy --stdout --credentials /path/to/secret.json >> operator.yaml

By default, it will install the latest version of the operator. You can specify a specific version using the --version flag:

jsctl operator deploy --credentials /path/to/secret.json --version v0.0.1-alpha.0

To view all available versions of the operator to install, you can use the jsctl operator versions command, which outputs the versions in order from oldest to newest.

See jsctl reference documentation for additional operator deployment options.

Create an installation

jsctl can be used to generate and/or apply configuration for the operator to create Jetstack Secure components.

This is an alternative to creating operator's configuration by hand.

Jetstack Secure Operator can be configured to create Jetstack Secure components via Installation custom resource, see documentation.

To create an Installation resource with jsctl, you can use the jsctl operator installations apply command which will apply the generated config to cluster or output it as yaml if --stdout flag is passed.

Generate base Installation resource

jsctl can be used as a quickstart config generator for operator's Installation resource for specific scenarios as an alternative to writing your own Installation resource from scratch.

jsctl operator installations apply --stdout > installation.yaml

This command generates a base Installation resource that configures the operator to install cert-manager and approver-policy.

Take a look at the generated config and see the Jetstack Secure operator documentation for how to configure additional resources like issuers.

Apply the installation to cluster when ready:

kubectl apply -f installation.yaml
Generate and apply Installation that configures Jetstack Secure components for Venafi TPP user

jsctl can be used to generate and/or apply operator configuration to set up a cluster with components relevant for Venafi TPP user.

TPP issuer with static credentials

Create a file with Venafi connection details and credentials connection.yaml:

my-default-zone:
  zone: <tpp-zone>
  url: <tpp-server-url>
  # access-token: <access-token could be used instead of username & password>
  username: <your-username>
  password: <your-password>

Run:

jsctl operator installations apply \
  --experimental-venafi-issuers="tpp:my-default-zone:foo" \
  --experimental-venafi-connections-config ./connection.yaml

This command will create and apply to cluster:

  • An Installation custom resource that will configure the operator to install cert-manager, approver-policy, a Venafi TPP ClusterIssuer named foo configured with the provided TPP URL and zone as well as an 'allow all' CertificateRequestPolicy for the ClusterIssuer and RBAC that allows cert-manager to use the policy

  • a Secret named foo-jsctl in jetstack-secure namespace with static credentials for foo ClusterIssuer.

TPP issuer with access token managed by venafi-oauth-helper

Create a file with Venafi connection details and credentials connection.yaml:

my-default-zone:
  zone: <tpp-zone>
  url: <tpp-server-url>
  username: <your-username>
  password: <your-password>

Note that only username and password (not access token) can be used with venafi-oauth-helper.

Run:

jsctl operator installations apply \
  --venafi-oauth-helper \
  --experimental-venafi-issuers="tpp:my-default-zone:foo" \
  --experimental-venafi-connections-config ./connection.yaml

This command will create and apply to cluster:

  • An Installation custom resource that will configure the operator to install cert-manager, approver-policy, venafi-oauth-helper, a Venafi TPP ClusterIssuer named foo configured with the provided TPP URL and zone as well as an 'allow all' CertificateRequestPolicy for the ClusterIssuer and RBAC that allows cert-manager to use the policy

  • a foo-voh-bootstrap Secret with the provided Venafi credentials that will be used as a bootstrap credentials by venafi-oauth-helper to create a dynamically refreshed access token for the foo ClusterIssuer (see venafi-oauth-helper docs for details)

cert sync with cert-discovery-venafi

cert-discovery-venafi can be used to sync certs in clusters to Venafi TPP.

Create a file with Venafi connection details and credentials connections.yaml:

foo-issuer-zone: # TPP zone for certs issued via `foo` ClusterIssuer (see below)
  zone: <tpp-zone>
  url: <tpp-server-url>
  username: <your-username>
  password: <your-password>
synced-certs-zone: # TPP zone where cert-discovery-venafi will sync other certs to
  zone: <tpp-zone>
  url: <tpp-server-url>
  access-token: <access-token>

Note that only username and password (not access token) can be used with venafi-oauth-helper whilst cert-discovery-venafi only accepts access token, so even if the two zones are the same, different connections with different sets of credentials are required.

Run:

jsctl operator installations apply \
  --venafi-oauth-helper \
  --experimental-venafi-issuers="tpp:foo-issuer-zone:foo" \
  --experimental-cert-discovery-venafi-connection="synced-certs-zone" \
  --cert-discovery-venafi \
  --experimental-venafi-connections-config ./connections.yaml

This command will create and apply to cluster:

  • An Installation custom resource that will configure the operator to install cert-manager, approver-policy, venafi-oauth-helper, cert-discovery-venafi configured with TPP URL and zone from synced-certs-zone Venafi connection, a Venafi TPP ClusterIssuer named foo configured with the provided TPP URL and zone from 'foo-issuer-zone' as well as an 'allow all' CertificateRequestPolicy for the ClusterIssuer and RBAC that allows cert-manager to use the policy

  • a foo-voh-bootstrap Secret with the provided Venafi credentials that will be used as a bootstrap credentials by venafi-oauth-helper to create a dynamically refreshed access token for the foo ClusterIssuer (see venafi-oauth-helper docs for details)

  • a Secret named access-token in jetstack-secure namespace with the access token from synced-certs-zone Venafi connection that cert-discovery-venafi uses to authenticate

See documenation for additional configuration options.

Users

List users

To list all users in your organization, you can use the jstcl users list command. You can provide the --json flag to produce the list as a JSON array. This could then be piped into a tool like jq for further processing.

jsctl users list

Add Users

To add a user to your organization, you can use the jsctl users add command and provide their email address. By default, users will be created as members. You can provide the --admin flag to create the user as an administrator of your organization.

jsctl users add [--admin] [email protected]

You can view the users within an organization using the jsctl users list command.

Remove Users

To remove a user from your organization, you can use the jsctl users remove command and provide their email address.

jsctl users remove [email protected]

You will be prompted for confirmation for user removal. If the given response is anything except y or Y the removal is cancelled. If you do not want to confirm your choice, provide the --force flag:

jsctl users remove --force [email protected]

Development

  • This repository depends on the private https://github.com/jetstack/js-operator Go module. To pull this module via Go you might need to set GOPRIVATE env var i.e GOPRIVATE="github.com/jetstack/*" go get -u
  • jsctl writes configuration (current organization) to a local file, on UNIX the path will likely be ~/.config/jsctl/config.json

Release process

To release a new version of jsctl:

  1. Create a new tag and push to upstream main branch

  2. Observe that Release Github Actions workflow runs and publishes a new Github release

  3. (If command line flags have changed) regenerate docs with make docs-gen locally, commmit and make a PR
