AWS ECR – Push Successful, Image Does Not Appear in Repo

amazon-ecramazon-web-services

We're using AWS ECR to host our docker images. We've noticed in a few rare instances that the docker push command can complete successfully, but the resulting image does not appear in the ECR container repository.

Any others experiencing this issue? Our ECR is in us-east-1

Output from our docker push script:

WARNING: login credentials saved in /home/ubuntu/.docker/config.json
Login Succeeded
The push refers to a repository [<our-id>.dkr.ecr.us-east-1.amazonaws.com/<our-repo>] (len: 2)
...
develop: digest: sha256:<redacted-sha> size: 36365
develop.<redacted-tag>: digest: sha256:<redacted-sha> size: 36370

We have noticed that the AWS ECR Repositories Console does not list recently pushed/tagged images in real time. Link: https://console.aws.amazon.com/ecs/home?region=us-east-1#/repositories (specify your region if necessary).

If you execute the following AWS CLI command, you will see all repos pushed. Even those that do not yet appear in the AWS ECR console.

 aws ecr list-images --repository-name=REPOSITORYNAME --region=REGION

Login Fail

dockerClient refuses the connection with "bad username or password"

The signature of the function you are calling to login is:

def login(self, username, password=None, email=None, registry=None,
          reauth=False, insecure_registry=False, dockercfg_path=None):

Note the position of the registry parameter. It is fourth in the list. So your call of:

regClient = dockerClient.login(username, password, registry)

Is passing your registry as the email since email is the third parameter. Suggest you change to something like:

regClient = dockerClient.login(username, password, registry=registry)

Python or shell?

Is the the right direction or should I be trying to implement this entirely with shell scripts? (Python has been especially valuable for the boto calls to describe what is in each registry)

Go with the Python.
