A bug was found in the Docker CLI where running docker login my-private-registry.example.com
with a misconfigured configuration file (typically ~/.docker/config.json
) listing a credsStore
or credHelpers
that could not be executed would result in any provided credentials being sent to registry-1.docker.io
rather than the intended private registry.
This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as soon as possible.
Ensure that any configured credsStore
or credHelpers
entries in the configuration file reference an installed credential helper that is executable and on the PATH
.
