Describe how to test a release payload from upstream CI

[m1kola]

Would be great to be able to test release payload that CI builds for PRs in the https://github.com/openshift/origin repo.

There are several problems we need to take into account while documenting it:

• Images are guarded with a pull secret, so we can not simply copy-paste image name from CI
• We might need ssh access to bootstrap node for debuging, so it's worth mentioning that the cluster should be in a dev vnet where ssh is allowed
• Images from the CI registry get garbage collected after a short period of time

---

Notes useful to resolve the ticket.

To get pull secret for the upstream CI:

• oc login against https://api.ci.openshift.org/
• oc registry login --to=- | jq -r '. | tostring | "pullSecret: '"'"'\(.)'"'"'"' to get the pull secret

Wondering if providing this pull secret via --pull-secret in az aro create will allow us to pull payload & images from the CI registry. I treid this quickly, but something failed (didn't have a chance to dig into details).
