Gardener: Just upgrade the machine-controller-manager component

[qiffang]

I use gardener to manage our kubernetes clusters.
I seems that this PR (

414) support local ssd for GCP. I just want to upgrade machine-controller-manager and i have build the image with machine-controller-manager latest code. But how should i update the image version of machine-controller-manager in gardener?

Thanks

You can overwrite images deployed by the provider extension, e.g. you can provide your own build of the MCM. Here is the default list of images used by the provider https://github.com/gardener/gardener-extension-provider-gcp/blob/master/charts/images.yaml

I am closing now the issue, if you need - please re-open it.

Hi @vpnachev
I try to edit gardener-extension-provider-gcp deployment to add overwrite images, but it always be modified back.

kubectl edit deploy gardener-extension-provider-gcp -n extension-provider-gcp-2x6xs

Hi @qiffang

the provider extension resources (specified in the provided chart of the ControllerRegistration) are deployed via a ManagedResource and reconciled back by gardener-resource-manager.
You can overwrite chart values directly in the ControllerRegistration like this, which will be propagated to all ControllerInstallations/Seeds:

apiVersion: core.gardener.cloud/v1beta1
kind: ControllerRegistration
metadata:
  name: provider-gcp
spec:
  resources:
  - kind: BackupBucket

  - kind: Worker
    type: gcp
  deployment:
    type: helm
    providerConfig:
      chart: "<base64 encoded chart>"
      values:
        image:

          images:
