Answer 1

if for some reason you can't upgrade awscli version, you can do a little string manipulation to make it work for you with sed.

for example:

$(aws ecr get-login --region eu-central-1 | sed -e 's/-e none//g')

this will drop the -e flag that is not supported and you should be able to login.
