Thanks for this 👍

I found some time to refactor the codebase a little and I have a ton of local changes that I'm still testing. I'll try and apply your work on top of it next week and hopefully cut a 0.2.0 release.

How does this handle vanilla k8s installations (that aren't OCP)? Check out operator-utils /utils.go/IsOpenShift & LookupOpenShiftVersion and let's evaluate if that tooling is still relevant or can be caught up as there are still a lot of teams using the IsOpenShift check & some using it for versioning as well.

I'm honestly not sure if these features translate back to k8s, but if not, we should probably gate-check that.

In particular, let's look at the bug mentioned here and see if we can clean up the util code and maybe do away with the hard-coded version mapping altogether? Not sure we can, but thought you may want to get familiar with that code and see if it has a home here.

@jeremyary: thanks, I'll check those utils methods and try to validate against k8s as well.

I verified it won't work with K8s. I will replace with utils methods

I reported a breaking change in the operator-sdk testing framework (operator-framework/operator-sdk#2731) which is blocking me to use operator-util methods in the test-cases.

@akoserwal There are some conflicts that need fixing up.

jamesnetherton · 2020-03-24T11:15:54Z

The integration test needs to be a bit smarter as the CI build only runs on OpenShift 3.x at present. So we only want to do assertions on consolelink CRs if the version is 4.x.

@jamesnetherton: yeah, I am working on it. thanks

Hi @akoserwal. Thanks for your work on this.

I left a few comments.

I think there's a potential nil pointer exception here. If the operator is not running on OpenShift >= 4.3, then consoleLink will still be appended to the actions slice as nil. When the actions loop runs during reconcile it'll encounter the nil action.

updated code to handle the nil pointer case

Just a question, does the removal of the ConsoleLink have to be done from a finalizer?

If you create the ConsoleLink with through action.deployResource(), it'll set a owner reference between the AtlasMap CR and the ConsoleLink.

Console Link (application menu, namespace dashboard) is cluster-scoped. Namespaced dashboard which is part of the console link is namespace scoped. We can not set owner reference for console-link. I am using the finalizer as a flag to allow the deletion of console-link before the Atlasmap cr gets deleted and removes the flag once console-link has been deleted.

Agree on cascading delete not working. However, we ended up doing this without a finalizer, by picking up the CR deletion reconcile call and cleaning it up in the reconcile loop the way we do adds and updates. See kiegroup/kie-cloud-operator#397

I removed the finalizer logic and handle in the reconciler. thank you for the suggestion.

There's another potential nil pointer exception here. GetClusterVersionSemVer has:

if errors.IsNotFound(err) { // default to OpenShift 3 as ClusterVersion API was introduced in OpenShift 4 openShiftSemVer, _ = semver.NewVersion("3") } else { return nil }

So if an error occurs that is not trapped by the IsNotFound condition, nil is returned and is not handled by the caller. I'm actually seeing this happen on a local Minishift cluster:

@akoserwal I'm happy with the latest changes. Just one final request...

I just created deploy/olm-catalog/atlasmap-operator/0.3.0/atlasmap-operator.v0.3.0.clusterserviceversion.yaml. Please can you add the additional permissions for ConsoleLink.
