I m trying to push a docker image to an Amazon ECR registry I m using docker client Docker version 1 9 1 build a34a1d5 I use aws ecr get-login --region us-east-1 to get the docker login creds Then I successfully login with those creds as follows docker login -u AWS -p XXXX -e none https dkr ecr us-east-1 amazonaws com WARNING login credentials saved in Users ar docker config json Login Succeeded But when I try to push my image I get the following error docker push dkr ecr us-east-1 amazonaws com image latest The push refers to a repository dkr ecr us-east-1 amazonaws com image len 1 bcff5e7e3c7c Preparing Post https dkr ecr us-east-1 amazonaws com v2 image blobs uploads no basic auth credentials I made sure that the aws user had the correct permissions I also made sure that the repository allowed that user to push to it Just to make sure that wasn t an issue I set the registry to allow all users full access Nothing changes the no basic auth credentials error I don t know how to begin to debug this since all the traffic is encrypted UPDATE So I had a bit of Homer Simpson D Oh moment when I realized the root cause of my problem I have access to multiple AWS accounts Even though I was using aws configure to set my credentials for the account where I had setup my repository the aws cli was actually using the environment variables AWS ACCESS KEY ID and AWS SECRET ACCESS KEY So when I did aws ecr get-login it was returning a login for the wrong account I failed to notice that the account numbers were different until I just went back now to try some of the proposed answers When I remove the environment variables everything works correctly I guess the motto of the story is if you hit this error make sure that the repository you are logging into matches the tag you have applied to the image

Can't push image to Amazon ECR - fails with "no basic auth credentials"

if you run $(aws ecr get-login --region us-east-1) it will be all done for you
