how to generate login password forAWS ECR with AWS CLI v2?

[lanlin]

there have some breaking changes from CLI v1 to v2. for v2 command to generate the ECR login password:

aws ecr get-login-password --region xxx  # for original region specific
aws ecr get-login-password --profile xxx  # for named profile config 

now copy the password string & paste to replace the below xxx (you can pipe to login directly, this is only for that you want to generate the password send to other people)

echo xxx | docker login --password-stdin -u AWS  https://xxx.dkr.ecr.xxx.amazonaws.com

ECR repository link format like this (you can get it from your aws ecr repositories list):

${aws_account}.dkr.ecr.${aws_region}.amazonaws.com/${repository_name}

Since CLI v2 the config file uses a different naming format than the CLI credentials file for named profiles, the config file includes the prefix word "profile".

PS: include the prefix word "profile" only when configuring a named profile in the config file. Do not use the word profile when creating an entry in the credentials file.
