This article mainly introduces what AWS ECR means. It is very detailed and has certain reference value. Friends who are interested must finish reading it.

ECR is a private docker image repository.

Components of ECR: registry, authorization token, repository, repository policy, image.

Registry: each AWS account provides a registry of ECR. You can create a repository of images in the registry and store the images in the registry.

Authorization token: a token that the docker client pushes and pulls an image to the ECR registry for authentication.

Repository: where docker images are stored.

Repository policy: control access to the repository image through the repository policy.

Image: making a mirror of the container

How to push the image to the ECR repository:

1. First create an ECR image repository

Aws ecr create-repository-- name of the repository-name repository

two。 Tag the image

Docker tag image name aws_account_id.dkr.ecr.us-east-1.amazonaws.com/ repository name

3. Gets the authentication string for the registry; (the authorization token provided by this command is valid for 12 hours)

Aws ecr get-login-no-include-email

4. Push image to ECR

Docker push aws_account_id.dkr.ecr.us-east-1.amazonaws.com/ repository

5. Delete repository

Aws ecr delete-repository-- repository-name repository name-- force

The size of the compressed image is displayed on the AWS console, while the image seen with docker images is uncompressed.
