Hello Everyone

How to authenticate docker in aws ecr?

Using the Amazon ECR credential helper (for docker client):

Amazon ECR provides a Docker credential helper which makes it easier to store and use Docker credentials when pushing and pulling images to Amazon ECR.

Step 1: Install Amazon ECR credential helper:

Step 2: Configure Amazon ECR credential helper:

Step 3: Perform docker operation in your AWS ECR repository:

Using an authorization token (for docker client):

An authorization token’s permission scope matches that of the IAM principal used to retrieve the authentication token. An authentication token is used to access any Amazon ECR registry that your IAM principal has access to and is valid for 12 hours.

Step 1: Get a new authorization token using get-login-password AWS cli command.

Step 2: Perform docker operation in your AWS ECR repository:

Using HTTP API authentication (for docker api):

Amazon ECR supports the Docker Registry HTTP API. However, because Amazon ECR is a private registry, you must provide an authorization token with every HTTP request. You can add an HTTP authorization header using the -H option for curl and pass the authorization token provided by the get-authorization-token AWS CLI command.

Step 1: Get API authorization token using get-authorization-token aws cli command.

Step 2: Perform docker API action in AWS ECR
