Che Workspace Operator

Che workspace operator repository that contains K8s API for Che workspace and controller for them.

Development

Build docker image

To build docker image run the following command in the project's root

docker build -t quay.io/che-incubator/che-workspace-controller:7.1.0 -f ./build/Dockerfile .

Run controller within Kubernetes cluster

# 1. Install CRDs
kubectl apply -f ./deploy/crds
# 2. Create che-workspace-controller which will hosts controller
kubectl create namespace che-workspace-controller
# 3. Deploy Plugin Registry
# [!MANUAL_ACTION]: Make sure that the right domain is set in `./deploy/controller_config.yaml` and `./deploy/registry/local/ingress.yaml`
kubectl apply -f ./deploy/registry/local
kubectl apply -f ./deploy/registry/local/k8s
# 4. Generate certificates for Webhook server by executing
./deploy/webhook-server-certs/deploy-webhook-server-certs.sh kubectl
# 5. Deploy Controller itself
# [OPTIONAL MANUAL ACTION] Modify ./deploy/controller.yaml and put your docker image and pull policy there.
kubectl apply -f ./deploy

Run controller within OpenShift cluster

The operator requires internet access from containers to work. By default, crc setup may not provision this, so it's necessary to configure DNS for Docker:

# /etc/docker/daemon.json
{
  "dns": ["192.168.0.1"]
}

# 1. Install CRDs
oc apply -f ./deploy/crds
# 2. Create che-workspace-controller which will hosts controller
oc create namespace che-workspace-controller
# 3. Deploy Plugin Registry
oc apply -f ./deploy/registry/local
oc apply -f ./deploy/registry/local/os
PLUGIN_REGISTRY_HOST=$(oc get route che-plugin-registry -n che-workspace-controller -o jsonpath='{.spec.host}' || echo "")
# 4. Generate certificates for Webhook server by executing
./deploy/webhook-server-certs/deploy-webhook-server-certs.sh oc
# 5. Deploy Controller itself
# [OPTIONAL MANUAL ACTION] Modify ./deploy/controller.yaml and put your docker image and pull policy there.
cat ./deploy/*.yaml | \
  sed "s|plugin.registry.url: .*|plugin.registry.url: http://${PLUGIN_REGISTRY_HOST}/v3|" | \
  oc apply -f -

Run controller locally

According to your Cluster do 1-4 steps from Kubernetes or OpenShift.

operator-sdk up local --namespace <your watched namespace>

Test run controller

1. Take a look samples workspace configuration in ./samples folder.
2. Apply any of them by executing kubectl apply -f ./samples/workspace_java_mysql.yaml -n <namespace>
3. As soon as workspace is started you're able to get IDE url by executing kubectl get workspace -n <namespace>

Run controller locally and debug

This depends on delve being installed (go get -u github.com/go-delve/delve/cmd/dlv). Note that at the time of writing, executing go get in this repo's directory will update go.mod; these changes should be dropped before committing.

Running the controller outside of the cluster depends on everything being in one namespace (e.g. che-workspace-controller).

1. Follow steps 1-5 for running the controller locally above
2. operator-sdk up local --namespace <your namespace> --enable-delve
3. Connect debugger to 127.0.0.1:2345 (see config in .vscode/launch.json)

Remove controller from your K8s/OS Cluster

# Delete all workspaces
kubectl delete workspaces.workspace.che.eclipse.org --all-namespaces --all
# Remove contoller
kubectl delete namespace che-workspace-controller
# Remove CRDs
kubectl delete customresourcedefinitions.apiextensions.k8s.io workspaceroutings.workspace.che.eclipse.org
kubectl delete customresourcedefinitions.apiextensions.k8s.io workspaces.workspace.che.eclipse.org
