[rdo-users] rdo container registry url returns 404

[Alan Pevec]

Hi Aneesh,

let's move discussion to the RDO users list so others can benefit and
there is also issue with TripleO docs which we need to clarify with
developers working on it.

This is wrong in docs, testing tag should not be used outside CI jobs
since it can change any time also it is not confirmed it is working at
all!

It is but there was an issue with tagging tripleo-passed-ci after
successful CI promotion, this is being worked on.
In the meantime, you can grab the hash from the last passed-ci RDO
trunk repository and use it as a tag:

$  python -c 'import urllib2;import
yaml;c=yaml.load(urllib2.urlopen("https://trunk.rdoproject.org/centos7-master/current-tripleo/commit.yaml"))["commits"][0];print
"%s_%s" % (c["commit_hash"],c["distro_hash"][0:8])'

# a quick test that container image is there:
$ skopeo inspect
docker://trunk.registry.rdoproject.org/master/centos-binary-nova-api:3b85715c6488a692fcdf4e4c6a589d77c60eb5a6_a3792c8d

Cheers,
