Description Artyom 2020-07-07 11:41:30 UTC
Description of problem:
Running the command 
oc adm must-gather --image=registry.stage.redhat.io/openshift4/performance-addon-operator-must-gather-rhel8
on the first try ends with the error
[must-gather      ] OUT namespace/openshift-must-gather-7z6lf deleted
error: gather did not start for pod must-gather-7tkkg: timed out waiting for the condition

The command ended on timeout because it takes time to fetch the new image and it does not look that the timeout argument works properly.

Under the code, I can see that we provide arguments in the wrong order - https://github.com/openshift/oc/blob/41ac95217bc52c10b114d2f5d9225ebd0c59e694/pkg/cli/admin/mustgather/mustgather.go#L428, we provide the timeout as the first argument when it should be the interval.

Version-Release number of selected component (if applicable):
master

How reproducible:
Always

Steps to Reproduce:
1. Run 
oc adm must-gather --image=registry.stage.redhat.io/openshift4/performance-addon-operator-must-gather-rhel8
2.
3.

Actual results:
On the first try, the command is failing on the timeout after the minute when the default timeout is 10 minutes.

Expected results:
The command should succeed or fail only after 10 minutes.
