When trying to run the get-login-password command in aws ecr, I get a message saying it's an invalid choice:

$ aws --region=us-west-1 ecr get-login-password
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help
aws: error: argument operation: Invalid choice, valid choices are:

Is this a Mac-only tool? ECR does seem to be installed but the issue is get-login-password. I installed the latest AWS client via these instructions https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-linux.html

amazon-ecr aws-cli ubuntu

AWS CLI have two versions available at the moment, get-login-password is only available in the v2 of the SDK/CLI.

aws ecr get-login-password --region eu-west-1 | docker login --username AWS --password-stdin 123456789.dkr.ecr.eu-west-1.amazonaws.com

Previous version v1 uses the following command. aws ecr get-login

eval $(aws ecr get-login --registry-ids 123456789 --region eu-west-1 --no-include-email)

You can use aws --version to check what version of the CLI is installed at the moment.

aws --version
aws-cli/2.0.38 Python/3.7.4 Darwin/20.3.0 exe/x86_64

As per your question is this a "Mac-only" tool? No this is available for Windows, Mac and Linux as well as for x86 and ARM architecture.

I've just ran their installation command and it works for me.
