aws-ecr:tldr:6a889

This command is used to authenticate and log in to an Amazon Elastic Container Registry (ECR) for a specified AWS account.

Here's the breakdown of the command:

• aws ecr get-login-password is a command provided by the AWS Command Line Interface (CLI). It retrieves an authentication token (password) that is required to log in to an ECR.
• --region ${region} is an option used to specify the AWS region where the ECR repository is located. ${region} is a placeholder that should be replaced with the desired AWS region (e.g., us-west-2).
• | is a pipe operator used to pass the output of the aws ecr get-login-password command as input to the next command.
• ${docker login} is the Docker CLI command used to log in to a Docker registry. ${docker login} is a placeholder that should be replaced with the appropriate Docker login command for your specific environment.
• --username AWS specifies the username to be used for the Docker login, in this case, it is set as "AWS".
• --password-stdin indicates that the password to authenticate should be read from the standard input.
• ${aws_account_id} is a placeholder for the AWS account ID associated with the ECR repository.
• .dkr.ecr.${region}.amazonaws.com is the domain suffix used in the ECR registry URL, based on the specified region.

Once you run this command with the relevant substitutions, it will retrieve the login password for the ECR in the specified region, pass it as the standard input to the Docker login command, and log in to the ECR using the provided AWS account ID and the corresponding ECR registry URL.
