Description Abhinav Dahiya 2020-05-19 18:06:08 UTC
Description of problem:

On GCP all resources are prefixed with infra-id, which currently is 12 chars with 6 chars used by random bit, leaving only 6 chars from cluster name. This causes trouble associating the cluster to jobs in CI as most of the identifyable characters are dropped from the resource names in CI due to this restriction.

Also because of the previous restriction, only one char are used from pool's name, making is highly likely to collide in cases there are more.

Reproduced with 4.5.0-0.nightly-2020-05-20-211028

If cluster name is set to yangyang0522, the infra_id will be yangya-hmt7b.

Verifying with 4.5.0-0.nightly-2020-05-22-054554
I set cluster name to yangyang1837642, but get the infra-id "yangya-ndsf5" which still uses the first 6 characters of cluster name. And the node name still use the first character of machine pool name. 
# oc get node
NAME                                             STATUS   ROLES    AGE    VERSION

yangya-ndsf5-m-2.c.openshift-qe.internal         Ready    master   129m   v1.18.2

yangya-ndsf5-w-c-s9kpm.c.openshift-qe.internal   Ready    worker   101m   v1.18.2

If I understand correctly, with the PR merged, the infra-id should have maximum length 27 characters, and the node name should have the machine pool name. It seems it is not fixed. Did I miss anything?

the CI run on that PR shows the latest wider names being used.

I think there is some problem with the installer version built in that nightly,

oc adm release info registry.svc.ci.openshift.org/ocp/release:4.5.0-0.nightly-2020-05-22-054554 --commits | grep installer

As you can see ^^ installer and installer-artifacts has different sha, and 8da3ffa23277b55b3ddbf53761063d22a30ce8a2 is the one you at least need, e2367c4f2b868cd5968fd3859dae2aa00aa7bcc4 doesn't have the change..

looking at newer builds, it seems like they are correct, so maybe try with new nightly.

make sure you check and include openshift-install version.

Thanks for the information. I saw the pr in that build change log so that I thought that build had included the change.

Verifying with 4.5.0-0.nightly-2020-05-24-223848

1. Set cluster name to yangyang1837642yangyangyangyang and install a cluster

The infra-id uses at most 21 characters from the cluster name.
