Upgrades from Ocata to Pike (containerized) missing container upload step

[Emilien Macchi]

By testing upgrades from Ocata (baremetal) to Pike (containerized) in https://review.openstack.org/#/c/461000/ - we found out that the upgrade process wasn't working well, the local registry is missing containers.

We think it could be a regression in https://github.com/openstack/tripleo-quickstart-extras/commit/90e703768326622eab1cf8dfa80daddccc3f88c8 and Wes is currently investigating https://review.openstack.org/#/c/493972 to see if uploading the containers actually help.

I'm setting Critical + alert on this one because it should be our first priority to test upgrades at this stage of the cycle.

so I confirm https://review.openstack.org/#/c/493972 will help though the upgrade process is not working yet, hitting timeout in infra, because it pulls *all* containers into the local registry (it takes 30 minutes).

We need to pull only what we need. I'll open a new bug for that.

> because it pulls *all* containers into the local registry (it takes 30 minutes).

If we have an infra cache available, would it be quicker to *not* pull the images to the undercloud registry, and just pull them (once) to the subnode we're testing?

For single node tests I'm not sure we gain anything by using the undercloud cache, as we end up copying the same images to two nodes, and these copies are serialized (container upload, and the pull we do during the deploy?)

The slowness could be caused partially by downloading images off dockerhub instead of using the local mirror. I've proposed a fix at https://review.openstack.org/494525

    upload containers to undercloud in upgrade scenario

    The upgrade container scenarios are not working atm.
    At first glance it appears the upload command is missing after the
    containers are downloaded to the undercloud.
