Let’s take a look at how our Support Team is ready to help customers with Docker Compose Push to ECR.

All about Docker Compose Push to ECR

The docker push command comes in handy in pushing our container images to an Amazon ECR repository. Furthermore, Amazon ECR helps create and push Docker manifest lists for multi-architecture images.

In fact, each image in the manifest list is already pushed to the repository. Today, our Support Techs are going to demonstrate how to push a Docker image.

1. First, we have to generate a login for ECR with the following command:

   aws ecr get-login-password
2. Next, we have to create a repository for each image before pushing the image.

   $ for r in $(grep 'image: \${DOCKER_REGISTRY}' docker-compose.yml | sed -e 's/^.*\///') > do > aws ecr create-repository --repository-name "$r" > done

   where DOCKER_REGISTRY is set to the amazon registry location in the .env file.
3. Next, locate the local image we want to push and run the following command in order to get a list of the container images in our system.

   docker images
4. After that, we have to tag our image with the Amazon ECR registry, repository as well as the optional image tag name combination we want to use. Here is the registry format:

   aws_account_id.dkr.ecr.region.amazonaws.com

   Additionally, the repository name has to tbe the same as the image repository. If we omit the image tag, by default, the tag latest is chosen.
5. After that, we can build and push images with the following commands:

   $ docker-compose build 
   $ docker-compose push
