Keycloak Operator

A Kubernetes Operator based on the Operator SDK for syncing resources in Keycloak.

Current status

This is a PoC / alpha version. Most functionality is there but it is higly likely there are bugs and improvements needed

Supported Custom Resources

The following Keycloak resources are supported:

  • Keycloak
  • KeycloakRealm

Keycloak

Represents a keycloak server for the Operator to interact with. The Operator reconciles resources in Keycloak to match the spec defined in the custom resource (an example of this can be found in /deploy/examples/keycloak.json).

KeycloakRealm

Represents a realm in a keycloak server. The Operator reconciles keycloak realms and ensures the realm in the keycloak instance is configured to match the definition in the custom resource.

For more information read more info on keycloak realms.

Test it locally

Note: You will need a running Kubernetes or OpenShift cluster to use the Operator

  • clone this repo to $GOPATH/src/github.com/integr8ly/keycloak-operator
  • run make setup/dep cluster/prepare code/run

Note that you only need to run setup/dep the first time. After that you can simply run make code/run.

You should see something like:

INFO[0000] Go Version: go1.10.2
INFO[0000] Go OS/Arch: darwin/amd64
INFO[0000] operator-sdk Version: 0.0.7

In a new terminal run make cluster/create/examples.

Deploying to a Cluster

Before the Keycloak Operator can be deployed to a running cluster, the necessary Custom Resource Definitions (CRDs) must be installed. To do this, run kubectl apply -f deploy/crds/.

Or alternatively create your own.

  • kubectl apply -f deploy/crds/Keycloak_crd.yaml
  • kubectl apply -f deploy/crds/KeycloakRealm_crd.yaml
  • kubectl apply -f deploy/rbac.yaml -n <NAMESPACE>
  • kubectl apply -f deploy/operator.yaml -n <NAMESPACE>

Deploying using operator lifecycle manager

operator lifecycle manager manages operators and other resources. To deploy this operator on OLM enabled cluster apply manifest file, edit line 5 of the manifest file to desired namespace:

kubectl apply -f deploy/olm-catalog/csv.yaml

Create operator CRD and RBAC rules:

  • kubectl apply -f deploy/crds/Keycloak_crd.yaml
  • kubectl apply -f deploy/crds/KeycloakRealm_crd.yaml
  • kubectl apply -f deploy/rbac.yaml

Create a keycloak

  • kubectl apply -f deploy/examples/keycloak_min.json

Create a keycloak realm

  • kubectl apply -f deploy/examples/keycloakRealm.json

Tear it down

make cluster/clean

Tests

Running unit tests:

make test/unit

Running e2e tests on a remote cluster:

NOTE: you must be logged in a remote cluster.

#build an image with enabled tests
make image/build/test

#push the operator image
docker push myimage

#run the test pod
make test/e2e

Release

Update operator version files:

Commit changes and open pull request.

When the PR is accepted, create a new release tag:

git tag v<version> && git push upstream v<version>

You can’t perform that action at this time.
