Create AWS ECR repository if it doesn't exist

Question

How can I create an AWS ECR repository if it doesn't already exist?

Answer 1

One liner to create a repo if it doesn't exist (or the describe command fails for any other reason):

aws ecr describe-repositories --repository-names ${REPO_NAME} || aws ecr create-repository --repository-name ${REPO_NAME} 

Answer 2

AWS makes the repository only if it doesn't exist. You can simply ignore the error & failure with
|| true in case if same repository exists:

aws ecr create-repository --repository-name <repo_name> || true
