Question

I am trying to build projects using Circle CI aws-ecr-orb to push to a private repository in AWS.

I get the error below:

Exited with code exit status 1
CircleCI received exit code 1

I'm trying to understand why the error is coming up.

Answer 1

I finally figured out the issue.

The issue was caused because I changed the tag mutability setting for the repository to IMMUTABLE.

All I had to do was to change the tag mutability setting for the repository to MUTABLE.

In Terraform AWS ECR module, I just had to add the settings below to the resource:

repository_image_tag_mutability        = "MUTABLE"
