aws-ecr:tldr:95f5a

This command is used to pull a Docker image from the AWS Elastic Container Registry (ECR) repository.

Here is the breakdown of each element in the command:

• docker pull is the command used to fetch or download a Docker image from a remote repository.
• ${aws_account_id} is a placeholder variable that should be replaced with the actual AWS account ID associated with the ECR repository.
• .dkr.ecr.${region}.amazonaws.com is the URL of the ECR registry specific to the respective AWS region.
• ${container_name} is a placeholder variable representing the name of the Docker container or repository within the ECR.
• ${tag} is a placeholder variable for the specific version or tag of the Docker image you want to pull.

When you replace the placeholders with the actual values, the command should look something like this:

docker pull 123456789012.dkr.ecr.us-west-1.amazonaws.com/my-container:latest

This command pulls the Docker image named my-container with the latest tag from the ECR registry located in the us-west-1 region and associated with the AWS account ID 123456789012.
