aws-ecr: Tag a local image for ECR.

docker

$ docker tag ${container_name}:${tag} ${aws_account_id}.dkr.ecr.${region}.amazonaws.com/${container_name}:${tag}

try on your machine

The command docker tag ${container_name}:${tag} ${aws_account_id}.dkr.ecr.${region}.amazonaws.com/${container_name}:${tag} is used to tag a Docker image with a new name and optionally move it to a different repository.

Here's what each part of the command does:

${container_name}:${tag}: This specifies the original name and tag of the Docker image that you want to tag. ${container_name} and ${tag} are variables that should be replaced with the actual values. For example, if your container name is "myapp" and the tag is "latest", it would be "myapp:latest".
${aws_account_id}.dkr.ecr.${region}.amazonaws.com: This specifies the Amazon ECR (Elastic Container Registry) endpoint that you want to use. ${aws_account_id} and ${region} are variables that should be replaced with your AWS account ID and the AWS region where your ECR repository is located. For example, if your AWS account ID is "123456789012" and your region is "us-west-2", it would be "123456789012.dkr.ecr.us-west-2.amazonaws.com".
/${container_name}:${tag}: This specifies the new name and tag for the Docker image after tagging. The image will be named ${container_name} with the specified ${tag}. For example, if your container name and tag are "myapp" and "latest" respectively, the new name and tag would be "myapp:latest".

Overall, this command assigns a new name and tag to a Docker image and moves it to an Amazon ECR repository.
