Amazon ECR Docker Credential Helper as a Docker image

This is Amazon ECR Docker Credential Helper from AwsLabs packaged as a Docker image.

Just add an executable shell script called docker-credential-ecr-login into your PATH:

1. If you are using EC2 instance profile:

   #!/bin/sh
   docker run \
     -i \
     --rm \
     -v /etc/ssl/certs:/etc/ssl/certs \
     redbadger/docker-credential-ecr-login $1

2. If you are using environment variables:

   #!/bin/sh
   docker run \
     -i \
     --rm \
     -e AWS_ACCESS_KEY_ID \
     -e AWS_SECRET_ACCESS_KEY \
     -e AWS_SESSION_TOKEN \
     -v /etc/ssl/certs:/etc/ssl/certs \
     redbadger/docker-credential-ecr-login $1

3. If you are AWS credentials:

   #!/bin/sh
   docker run \
     -i \
     --rm \
     -v /etc/ssl/certs:/etc/ssl/certs \
     -v $HOME/.aws/credentials:/root/.aws/credentials \
     redbadger/docker-credential-ecr-login $1

Then modify ~/.docker/config.json to let Docker know to use the helper (substituting your AWS account and region):

{
  "credHelpers": {
    "${account}.dkr.ecr.${region}.amazonaws.com": "ecr-login"
  }
}

or (for all registries)...

{
  "credsStore": "ecr-login"
}
