Issue Installing OLM in Openshift Namespace

[atef23]

Bug Report

What did you do?
I provisioned an Openshift cloud cluster through Red Hat's openTLC labs system so the cluster came preconfigured with some components I don't have full visibility into. I created a new namespace and attempted to install olm using the operator-sdk CLI.

What did you expect to see?
Expected to be able to install OLM if it wasn't there already.

What did you see instead? Under which circumstances?
It seems that some components of OLM are present but not enough to allow for an uninstall. Stuck in a catch-22 where I can't install due to these components but also can't run the uninstall command

`[atefaziz@localhost projects]$ operator-sdk olm status

FATA[0002] Failed to get OLM status: no existing installation found

[atefaziz@localhost projects]$ operator-sdk olm install

INFO[0002] Fetching CRDs for version "latest"

INFO[0003] Fetching resources for version "latest"

FATA[0005] Failed to install OLM version "latest": detected existing OLM resources: OLM must be completely uninstalled before installation

[atefaziz@localhost projects]$ operator-sdk olm uninstall

FATA[0002] Failed to uninstall OLM: no existing installation found
`

Environment

• operator-lifecycle-manager version:

operator-sdk version: "v0.17.0"

• Kubernetes version information:

Openshift version:
4.4.8

Ah, looks like this is a 3.11 cluster, so the cluster component comment I made doesn't apply.

Does the sdk have a verbose option for these commands? I'm not sure exactly what steps the sdk does when it attempts to install/uninstall OLM, but most likely it is just attempting to apply CRDs, then deployments/rbac/service accounts, then a few CRs.

@kevinrizza sorry that was my CLI version. The cluster version is 4.4.8. I've updated it above. Hmm yeah I'm going through the source trying to see which existing resources exist which are preventing my installation from proceeding.

[kevinrizza]

@atef23 Ah, yeah, so in that case OLM is a core openshift component and the sdk won't be able to uninstall it without first putting the cluster in an unsupportable state. Is there a reason you are attempting to uninstall olm, or attempting to install a different version?

[atef23]

@kevinrizza ah ok so I guess the issue was that I was using a OC 3.x CLI with a 4.x cluster so it wasn't able to detect the olm installation? I think you're right the olm installation was already there but when I ran the:

operator-sdk olm status

command, it said there was no installation

I manually applied the olm.yaml and crds.yaml from the latest release: https://github.com/operator-framework/operator-lifecycle-manager/releases and after doing that, my operator-sdk olm status command was successfully showing the installation:

`[atefaziz@localhost Downloads]$ operator-sdk olm status

INFO[0007] Fetching resources for version "0.15.1"

@kevinrizza thanks for your input, I will close the issue
