Description

Description of problem:

Have 6 runs of techpreview jobs where the jobs fails due to the MCO:

{Operator degraded (RequiredPoolsFailed): Unable to apply 4.12.0-0.ci.test-2022-09-21-183414-ci-op-qd6plyhc-latest: error during syncRequiredMachineConfigPools: [timed out waiting for the condition, error pool master is not ready, retrying. Status: (pool degraded: true total: 3, ready 0, updated: 0, unavailable: 3)] Operator degraded (RequiredPoolsFailed): Unable to apply 4.12.0-0.ci.test-2022-09-21-183414-ci-op-qd6plyhc-latest: error during syncRequiredMachineConfigPools: [timed out waiting for the condition, error pool master is not ready, retrying. Status: (pool degraded: true total: 3, ready 0, updated: 0, unavailable: 3)]}

looking at the MCD logs the master seems to go degraded in bootstrap due to the rendered config not being found?

However looking at controller a rendered-config was generated correctly but it's not the missing config from above:

So far I see this in the following techpreview jobs:

The above jobs affect the k8s 1.25 bump and are blocking the job.

There are also other occurances not in our PR:

Also see a quick search:

Did something change that would affect tech preview jobs?

Also note, this seems like a new failure. I have some of these jobs passing in the last ~ 8 days.
