Server setup for the Amazon Container Registry (ECR)

We recently moved our docker images to the Amazon Container Registry (ECR). To access ECR in docker you need to install and configure the amazon-ecr-credential-helper. This post contains a short writeup on the necessary steps.

Installation

$ apt update
$ apt install amazon-ecr-credential-helper

Set the AWS credentials:

$ mkdir ~/.aws
$ nano ~/.aws/credentials

[default]
aws_access_key_id=ABCDEFGABCDEFG
aws_secret_access_key=abcdefgabcdefgabcdefgabcdefg

Set the AWS default options (yours might be different):

$ nano ~/.aws/config

[default]
region=eu-north-1
output=json

Update the docker configuration (replace 1234567890 with your registry id):

$ nano ~/.docker/config.json

{
  "credHelpers": {
    "1234567890.dkr.ecr.eu-north-1.amazonaws.com": "ecr-login"
  },
  "credsStore": "ecr-login"
}
