Docker login hangs - AWS EC2 AMI Image

Expected behavior

execution of following command will finish in several seconds (always)

eval $(aws ecr get-login --region eu-central-1 --debug --profile xxx)

Actual behavior

execution of following command SOMETIMES get stucked on ‘docker login’ and even after one hour of waiting it does not continue

eval $(aws ecr get-login --region eu-central-1 --debug --profile xxx)

Additional Information

I tried to set up debug mode and I can see aws-cli client was able to get authentication token from remote service. And it hangs on docker login itself…

I’m using AWS EC2 service
