Description
SYMPTOM:
As per NEXUS-12711, deleting an image with Docker API would be supported, but if multiple tags are used, Nexus does not remove all tags.
REPRODUCE STEPS:
1. Prepare test image
_NEXUS_HOST="<YOUR_NEXUS_HOST:DOCKER_PORT>"
docker login ${_NEXUS_HOST}
docker pull alpine:3.7
docker tag alpine:3.7 ${_NEXUS_HOST}/alpine:3.7
docker push ${_NEXUS_HOST}/alpine:3.7
docker tag ${_NEXUS_HOST}/alpine:3.7 ${_NEXUS_HOST}/alpine:testtag
docker push ${_NEXUS_HOST}/alpine:testtag
2. Try deleting it
# Find the digest curl -s -D/dev/stdout -u 'admin:admin123' -H 'Accept:application/vnd.docker.distribution.manifest.v2+json' -k https://${_NEXUS_HOST}/v2/alpine/manifests/3.7 | grep Docker-Content-Digest Docker-Content-Digest: sha256:92251458088c638061cda8fd8b403b76d661a4dc6b7ee71b6affcf1872557b2b # Use above digest in delete curl -v -u 'admin:admin123' -X DELETE -k https://${_NEXUS_HOST}/v2/alpine/manifests/sha256:92251458088c638061cda8fd8b403b76d661a4dc6b7ee71b6affcf1872557b2b
3. Run "Docker - Delete unused manifests and images" task against this testing docker repository.
ACTUAL BEHAVIOUR:
The curl -X DELETE does not delete the "testtag".
The docker gc task also does not delete this tag.
EXPECTED BEHAVIOUR:
When deleting an image with Docker API, it should delete all tags.
Or "Docker - Delete unused manifests and images" should delete those orphaned tags.
