Overview

Used when pushing to Docker Hub.

docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: ...

Login into an Arbitrary Registry

docker login <registry-url>

Logging into an AWS ECR:

docker login -u AWS -p [...]  https://something.ecr.us-west-2.amazonaws.com

For more details see Amazon ECR - Configure Access.

TODO

  • How can I tell if I am logged in?
  • Where are the credential kept?
  • For how long am I authenticated?
  • What happens if it expires - any danger in using stale images instead of a clear error message? Research needed.
