Artifactory & Docker


$ docker login dhlecsam-docker-dev-fd.artifactory-us.dhl.com -u USERNAME
$ docker tag NAME:VERSION dhlecsam-docker-dev-fd.artifactory-us.dhl.com/devops/NAME:VERSION
$ docker push dhlecsam-docker-dev-fd.artifactory-us.dhl.com/devops/NAME:VERSION

Removing Signatures

If you get the “Error: Copying this image would require changing layer representation, which we cannot do: Would invalidate signatures” error message, there are two solutions, according to this RH Knowledgebase Article.

  1. Using skopeo copy or skopeo sync. This is also more efficient, since it doesn’t uncompress or unpack the artifact. skopeo sync --src docker --dest docker SRC_REPO/NAME:VERSION DEST_REPO/NAME:VERSION.

  2. Use –remove-signatures: podman push --remove-signatures REPO/NAME:VERSION

Unauthorized

If you get an error message with “FATA[0001] … unauthorized: No permission to write manifest” use skopeo sync --dest docker --src docker to add the artifact.
