docker login unknown shorthand flag: 'e'

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.

I had the same issue however following Scott Stensland's answer did not solve it.

In case it will happen to someone else, dropping '-e none' from the command solved the issue.

add this to your call

--no-include-email

here is the new valid syntax :

aws ecr get-login   ${normal_params_here}   --no-include-email
aws ecr get-login   --region us-east-1      --no-include-email  # for example

This new option is available in AWS CLI as of version 1.11.91 released on 05/23/2017 ... issue this to upgrade :

pip install --upgrade awscli

https://github.com/aws/aws-cli/issues/1926

to quote :

"You should have received an email notification from Amazon around May 23 2017 about the new --no-include-email flag on aws ecr get-login for compatibility with [Docker] 17.06.0"

For example after I issue following

aws ecr get-login   --region us-east-1      --no-include-email  

it shows me following output

docker login -u AWS -p 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 https://092412696969.dkr.ecr.us-east-1.amazonaws.com
