I am using Mobaxterm and starting a local bash terminal, and trying this command. But seeing an error. The same command is working from the cmd windows prompt or powershell. Any suggestions on workarounds, really appreciate it. I played with some settings that are already in the mobaxterm, but none worked.

/home/mobaxterm>docker login abcdef.azurecr.io
Error: Cannot perform an interactive login from a non TTY device

Try adding winpty before the docker ... command.

It enables TTY on Windows. Useful for GitBash, Putty and MobaXTerm.

$ winpty docker login $ACR_REGISTRY
Username: appacr
Login Succeeded

This is a docker error. Each Repo needs to have it's own environment variables set up. If you don't set up the DOCKER_USERNAME and DOCKER_PASSWORD in your model in the Repository settings, it would raise that confusing docker terminal (tty) error.


Use the --password-stdin flag as specified in the docs.

aws ecr get-login-password | docker login --username AWS --password-stdin aws_account_id.dkr.ecr.region.amazonaws.com

For me, the issue was with AWS ECR and I simply needed to update my aws cli.

AWS-CLI, version 2 installation instructions for Mac: https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-mac.html

You'll find similar instructions for other OS's there as well.


Try specifying the region in the aws ecr statement such as this example provided here:

aws ecr get-login-password --region region | docker login --username AWS --password-stdin aws_account_id.dkr.ecr.region.amazonaws.com

When I tried this to resolve the error I also noticed that AWS is finicky (unwilling to accept reasonable mistakes, for the non-english-native users) about how you define the region variable though. For example, us-west-2, while good enough in the --password-stdin aws_account_id.dkr.ecr.region.amazonaws.com part of the call, needed to be specified further as us-west-2b within the aws ecr get-login-password --region region portion of the command.

Hope this helps!


I had same issue on m1 Mac and the solution is refreshing the artifactory token.
