Helm tests will fail. Need to change api version of cert-manager here: https://github.com/eclipse/che/blob/master/deploy/cert-manager/che-cluster-issuer.yml

I was able to deploy devworkspace-controller in Ocp 4.X and also in minikube. I've create workspaces in both platform using samples: https://github.com/devfile/devworkspace-operator/tree/master/samples

Does this mean that we will need to change chectl whenever devworkspace-operator decides to add or remove a file from the deployment? Wouldn't it be better to just generically apply all the files in the deploy/deployment/${PLATFORM}/objects ?

@metlos Honestly I preffer to add one by one the objects because for example if one of the objects exist in cluster whole installation will fail.

Anyway if you remove/add objects in devworkspace you need to change chect server:delete.

I was trying to override the namespace by running:

bin/run server:deploy -p minikube --workspace-engine=dev-workspace --dev-workspace-controller-namespace=dw-ctrl

and got this error:

Create ServiceAccount devworkspace-controller-serviceaccount in namespace dw-ctrl
      → the namespace of the provided object does not match the namespace sent on the request

devworkspaceConfigMap -> devWorkspaceConfigMap

at milestone 1 we must guarantee that DevWorkspace Engine it not enabled on the cluster where Web Terminal is enabled.

So, apart from checking if mutating webhooks cfg exist, it would be cool to check the configured namespace inside. It's the example of Mutating Webhooks created by Web Terminal

apiVersion: admissionregistration.k8s.io/v1
kind: MutatingWebhookConfiguration
metadata:
  labels:
    app.kubernetes.io/name: devworkspace-webhook-server
    app.kubernetes.io/part-of: devworkspace-operator
  name: controller.devfile.io
webhooks:
- admissionReviewVersions:
  - v1beta1
  clientConfig:
    ...
    service:
      name: devworkspace-webhookserver
      namespace: openshift-operators
      path: /mutate
      port: 443
  ...
  name: mutate.devworkspace-controller.svc
  namespaceSelector: {}
  objectSelector: {}
  reinvocationPolicy: Never
  rules:
  ...
- admissionReviewVersions:
  - v1beta1
  clientConfig:
    service:
      name: devworkspace-webhookserver
      namespace: openshift-operators
      path: /mutate
      port: 443
  ...

Pay attention on namespace: openshift-operators.

Also, about Web Terminal presence can tell Subscription:

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  labels:
    operators.coreos.com/web-terminal.openshift-operators: ""
  name: web-terminal
  namespace: openshift-operators
spec:
  channel: alpha
  installPlanApproval: Automatic
  name: web-terminal
  source: redhat-operators
  sourceNamespace: openshift-marketplace
  startingCSV: web-terminal.v1.1.0

But in general it's going to break DevWorkspaces, if there is another devworkspace controller deployed.

So, the smart logic on Chectl side could be (at least in my opinion ;) ):

1. There is no need to provide an ability to override devworkspace operator namespace, so let's just remove it.
2. Then chectl checks and fails if Web Terminal installed (Subscription exists).
3. Then chectl checks if mutatingwebhooks exists, and their namespace is different than devworkspace-operator - checlt fails and tells that WebTerminal is not uninstalled properly (if namespace if openshift-operators) or another devworkspace controller is already deployed in namespace X (it can be evaluated on chectl with webhooks object).

What if a resource with v1alpha1 or v1alpha2 appear? What if it then turned into v1beta2?
According to the current strategy, we'll have to add several methods per version.
To me it is better to have version as second parameter (maybe default to v1)

[tolusha]

Agree. But let's keep as is for now.

[mmorhun]

ok
