Add missing deployment probes #13563

skonto · 2022-12-19T12:18:50Z

partially fixes knative/pkg#1048 for now.

Proposed Changes

Adds probes to deployments that don't have them. Webhooks call drain so no need. Activator, autoscaler have already.
Similar to Add readiness and liveness probes in controller eventing#6566
Asked also here Controller has no livenessProbe and readinessProbe #13430
It can be moved to knative.pkg for generic use if we want to.

Release Note

Controllers now have liveness and readiness probes

Failures seem irrelevant:

jq: error (at <stdin>:1): Cannot index string with string "tag_name"```

It seems like the intent of the linked issue was to add this logic to the sharedmain package - why not make the necessary changes in knative/pkg ?

cmd/default-domain/main.go

@@ -226,5 +219,4 @@ func main() {
 }

 logger.Info("Updated default domain to: ", domain)

Shutdown was blocking before and now it's not. This means main will exit and run defer's etc.

Ah yes, correct will fix. Just need to block on the context: <-ctx.Done() or something.

skonto · 2023-01-18T09:29:54Z

Ok I will move the logic in the knative/pkg I agree it would be useful there and then update the PR here to test it.

(When you update pkg, can you reference this PR, so we can track when this should be revised?)

skonto · 2023-02-17T11:34:28Z

@dprotaso gentle ping, this should be quick.
