Description Partha Aji 2017-11-16 06:30:14 UTC 
# Create a docker hub account. (https://cloud.docker.com/) 
# Install docker on a machine
# Run the following commands 
<pre>
docker login -u <username> docker.io
docker pull alpine
docker tag docker.io/alpine:latest docker.io/<username>/alpine:latest
docker tag docker.io/alpine:latest docker.io/<username>/alpine:greatest
docker push docker.io/<username>/alpine
</pre>
# On your katello ui create a docker repo with the following data -> name: repo1,  feed: https://registry-1.docker.io , upstream: <username>/alpine
# Sync repo1. Make sure you see a repo with 2 tags 
# Now go to https://cloud.docker.com/swarm/<username>/repository/docker/<username>/alpine/tags and delete the "latest" tag
# Sync repo1.

Expected:
Successful synced repo with 1 tag

Actual:
Successful sync but wrong tag information. You still see 2 tags

Upstream bug assigned to paji
Comment 4 Partha Aji 2017-11-16 21:21:10 UTC 
Apologize the suggested steps were slightly off. The above steps actually do the expected thing. The bug was more about updating a tag to a new manifest is not handled correctly.
Here is the new set of steps

# Create a docker hub account. (https://cloud.docker.com/) 
# Install docker on a machine
# Run the following commands 

<pre>
$ mkdir images
$ cd images
$ docker login -u <username> docker.io

$ cat <<EOT > Dockerfile
FROM alpine
RUN touch bar
EOT

$ docker build -t alpine:latest  .
$ docker tag alpine:latest docker.io/<username>/alpine1:latest
$ docker push docker.io/<username>/alpine1:latest
</pre>

# On your katello ui create a docker repo with the following data -> name: repo1,  feed: https://registry-1.docker.io , upstream: <username>/alpine1
# Sync repo1. Make sure you see a repo with 1 tag
# Go to repo1 details -> click on the link next to the DockerManifest number
# Make a note on the digest numbers where "latest" tag points to 
# back on the docker terminal run the following commands 
<pre>
$ cat <<EOT > Dockerfile
FROM alpine
RUN touch foo
EOT

$ docker build -t alpine:latest  .
$ docker tag alpine:latest docker.io/<username>/alpine1:latest
$ docker push docker.io/<username>/alpine1:latest
</pre>
# On your katello ui Sync repo1 again. Make sure you see a repo with 1 tag
# Go to repo1 details -> click on the link next to the DockerManifest number

Expected:
4 Manifests with the "latest" pointing to different digests from the prior one

Actual:
4 Manifests with the "latest" pointing to same digest from the prior one
Comment 5 Satellite Program 2017-11-17 19:18:02 UTC 
Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/21683 has been resolved.
Comment 6 Evgeni Golov 2017-11-22 10:27:27 UTC 
Hey Partha,

this does not cherrypick cleanly, and before I go and break more than I want, I thought you'd do the pick for me? :))

Thanks!
Comment 9 Peter Ondrejka 2018-01-02 13:56:30 UTC 
Verified on Satellite 6.3 snap 30, after changing and resyncing the repo, the manifests digests are correctly updated.
