I’m not entirely sure when the change happens, but recently as I was upgrading
AWS CodeBuilds to use a newer version of Ubuntu, I ran into some problems with
aws ecr get-login.
Without making any code changes, my build started to fail with the following:
[Container] 2021/06/21 20:44:19 Running command $(aws ecr get-login --no-include-email --region us-east-1)
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:

help
At a glance I spotted the get-login-password and jumped to the conclusion that
they simply renamed the command. Easy fix!
Except that assumption was wrong, and my next build failed a bit differently:
[Container] 2021/06/21 21:16:25 Running command $(aws ecr get-login-password --no-include-email --region us-east-1)
Unknown options: --no-include-email
At this point it was time to do some digging to figure out what the new syntax was supposed to be.
Turns out, the newer command didn’t need any of the arguments and could be
easily piped directly to the docker login command as such:
[Container] 2021/06/21 21:21:46 Running command aws ecr get-login-password | docker login --username AWS --password-stdin $AWS_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com
Login Succeeded
And we were off to the races and my builds started to pass again!
