Publish helm chart to ECR

Publishing a Helm package to an AWS ECR (Elastic Container Registry) private repository involves several steps:

1. Package the Helm chart
2. Create an ECR private repository
3. Authenticate Helm to your ECR private registry
4. Push the Helm chart to ECR private registry

​

1. Package as Helm chart

To package as helm chart please refer this article.

2. Create an ECR private repository

1. Login to AWS console.
2. Go to ECR console.
3. Switch to the preferred AWS region where you want to create the ECR private repository.
4. Create a private repository,
   1. In the left navigation pane, click on Private registry -> Repositories.
   2. Click on the Create repository button.

  aws ecr get-login-password \
       --region <aws_region> | helm registry login \
       --username AWS \
