vpa-autoscaler-updater pod can't adjust cert-manager deployment, there is an error:

VPA doesn't adjust Deployments, it adjusts the Pods that are managed controllers.
Can you print the details of the pod in the cert-manager Deployment?

Do you have any other VPA objects on this cluster?
Or do you have steps to reproduce this locally?

How many containers are defined in the cert-manager-cainjector Deployment?

@adrianmoisey

I've looked into this more, the only way I can reproduce it is as follows:

  1. Make a deployment with 2 containers in each Pod.
  2. Setup a VPA for them
  3. Wait for the recommendation
  4. Remove one of the containers

the VPA Updater now gives the same error you see, since the container doesn't exist for a recommendation that it has.

The error message you see is because the VPA object has 2 recommendations for that Deployment, one for "cert-manager" and one for "cert-manager-cainjector".

I'm unsure how it got in this state, but the error message isn't harmful.

We should possibly figure out a way to garbage collect this recommendation or to suppress the error

Wait, there are 3 different deployments for cert-manager stuff and also 3 vpa for each of them
