Can you explain how it works? How to test it?

svor · 2021-04-22T13:47:11Z

Hi @skabashnyuk I've updated the description, please let me know if something is unclear

amisevsk

I haven't tested changes but it makes sense to me. To be clear, the added RBAC is still restricted to the workspace's namespace, right?

sleshchenko

The only concern I have with this PR, it does not seem to affect existing users, who have SA already initialized, but I'm happy to be wrong here https://github.com/svor/che/blob/sv-metrics/infrastructures/kubernetes/src/main/java/org/eclipse/che/workspace/infrastructure/kubernetes/namespace/AbstractWorkspaceServiceAccount.java#L113

@metlos I remember you worked in this area and we already discussed how we should update/why we should not update SA and roles, but I don't remember details.

skabashnyuk · 2021-04-26T07:11:15Z

Please merge the latest master to fix the build check.

@metlos I remember you worked in this area and we already discussed how we should update/why we should not update SA and roles, but I don't remember details.

That is correct. The service account is only created once and not touched afterwards. Maybe we should revisit that and make sure the service account has all the rolebindings we require (and keep any additional that the admin may have added there).

metlos

LGTM, but as @sleshchenko said, we need to follow this up by another issue where we should make sure the service account has bindings to all the roles we require.

Who can do that(create an issue)?

svor · 2021-04-28T09:01:51Z

@skabashnyuk here is the issue #19697
@metlos could you please add some additional information into the issue if it is required
