Cause: must-gather-helper pod chooses wrong deployment yaml
Consequence: must-gather-helper pod fails to come up as it tries to found invalid rook secret

We have two templates for must-gather, one to use for pre-4.6 releases where ROOK_ADMIN_SECRET is used, that template is called standard template
and then there is latest template for 4.6 and above which uses ROOK_CEPH_USERNAME and the code which chooses the template is pretty straight forward.
if [[ $current_version -ge 460 ]]; then
apply_latest_helper_pod "$ns" "$operatorImage"
else
apply_standard_helper_pod "$ns" "$operatorImage"
fi
This issue is happening because the standard template is being used though the above code is in place.
We get the value of $current_version by running this command
>> oc get csv --no-headers | awk '{print $5}' | tr -dc '0-9'
Now, in this cluster following is the result of "oc get csv"
[muagarwa@mudits-workstation ~]$ oc get csv
NAME DISPLAY VERSION REPLACES PHASE
ocs-operator.v4.7.2 OpenShift Container Storage 4.7.2 Succeeded
ocs-osd-deployer.v0.0.1 OCS OSD Deployer 0.0.1 Succeeded
prometheusoperator.0.47.0 Prometheus Operator 0.47.0 prometheusoperator.0.37.0 Succeeded
route-monitor-operator.v0.1.345-ee53105 Route Monitor Operator 0.1.345-ee53105 route-monitor-operator.v0.1.343-e469921 Succeeded
[muagarwa@mudits-workstation ~]$
We always expect single line output of this command but because of multiple lines of output, the value of $current_version is 47200103700134553105 :)
This is really out of bound and the else logic will come into picture and we will end up in applying the standard template.
Neha, if I am not wrong we will have multiple CSVs in case multiple operators are installed?
Pulkit, do we still need two templates. It was required for 4.5 and below and now we can remove this logic and keep the latest template only.
WDYT? If you agree, I will send a PR to remove the standard template and this logic.
Also, we are hitting the same in BZ #1978541 which is a customer case and we need to think of a workaround to unblock the customer.
IMO, this is a real blocker and should be backported to 4.6.z and 4.7z too.
Can we just run
>> oc get csv --no-headers | grep ocs-operator | awk '{print $5}' | tr -dc '0-9'
instead?
To me, it seems like the simplest fix and the most robust one

It was required to support pre 4.6 releases only. *** Bug 1978541 has been marked as a duplicate of this bug. *** Do we have the issue in 4.8 too? Are we backporting it to 4.7 once 4.8 is verified (In reply to Neha Berry from comment #7) > Do we have the issue in 4.8 too? We have the problem in 4.6/4.7/4.8 > Are we backporting it to 4.7 once 4.8 is verified Yes, I have created a clone for 4.7 and marked it for 4.7.3. We should backport to 4.6 also as I am not able to think of any workaround. |
