Helm (built docker image) really heavy on cloud build pipeline and affect execution time

[Emixam23-FCMS]

Affected builder image

gcr.io/cloud-builders-community/helm

The image built for helm to be used on cloud build is very (very) heavy, more than 3GB
https://github.com/GoogleCloudPlatform/cloud-builders-community/tree/master/helm

Expected Behavior

I would like the build to result to a smaller image so the cloud build step can execute faster (as the pull would be less significant)

Actual Behavior

The image built for helm to be used on cloud build is very (very) heavy, more than 3GB

I have same problem. Due to big size of the Helm docker image the duration time of the deploy step is 00:01:37.

My deploy step in cloudbuild.yaml:

  - name: gcr.io/$_GOOGLE_CLOUD_PROJECT/helm
    id: Deploy chart
    args:
      - upgrade
      - -i
      - my-project
      - ./my-project-chart
      - -f
      - ./my-project-chart/values.yaml
    env:
      - KUBECONFIG=/workspace/.kube/config
      - TILLERLESS=true

I'am using Kaniko for building of the docker images and duration time is 5-10 seconds but deploy step is almost 2 minutes.
Any idea how to speed up?

Thank you.

Ended up building a custom image for helm.

cloud-builders-community/helm: 1.1GB
this image: 82.4MB
