Migrate helm chart from public repository to private

I'm trying to deploy some services using helm chart on AWS EKS.

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install postgresql --version 8.6.4 bitnami/postgresql

After I run helm command, pod is not created because connection to docker.io is blocked in the EKS.

$ kubectl describe po 
...

How can I change repository domain from docker.io to my ECR repository?

  1. I want to push this chart to my ECR repository.
  2. I want to make chart to pull the image not from docker.io but from my ECR repository.
Solution

  • How about try to override the repository domain value in values.yaml of the bitnami/postgresql using --set. Refer here for more details.

    image:
  registry: docker.io
  repository: bitnami/postgresql
  tag: 11.10.0-debian-10-r24

    You may override above image.registry value as follows.

    $ helm install postgresql \
  --set image=your-registry/bitnami/postgresql:11.10.0-debian-10-r24 \
  --version 8.6.4 bitnami/postgresql
