Unable to fetch ECR docker image

Question

When I am trying to pull docker image from ECR, I am getting the below error:

Get https://3242344.dkr.ecr.ap-south-1.amazonaws.imagename/latest: no basic auth credentials

Docker service is running fine and I am able to list the repositories.

Answer 1

First, you need to Authenticate your Docker logins to the Amazon ECR:

aws ecr get-login --region <<region>> --no-include-email

Refer below link for Amazon ECR Registries authentication: https://docs.aws.amazon.com/AmazonECR/latest/userguide/Registries.html#registry_auth

Describe your image within a repository by using below command:

aws ecr describe-images --repository-name amazonlinux

Pull the image by using below command:

docker pull aws_account_id.dkr.ecr.us-west-2.amazonaws.com/amazonlinux:latest

For more information please refer below link: https://docs.aws.amazon.com/AmazonECR/latest/userguide/docker-pull-ecr-image.html

Answer 2

You need to retrieve the docker login command using AWS CLI

$(aws ecr get-login --no-include-email --region <your region>)
