Today I rebuilt the Docker images that are used by the `webservice --backend=kubernetes` command. This is actually a normal thing that we do periodically in Toolforge to ensure that security patches are applied in the containers. This round of updates was a bit different however in that it is the first time the Debian Jessie based images have been rebuilt since the upstream Debian project removed the 'jessie-backports' apt repo.
Everything should be fine, but if you see weirdness when restarting a webservice or other Kubernetes pod that looks like it could be related to software in the Docker image please let myself or one of the Toolforge admins know by either filing a Phabricator bug report or for faster response joining the #wikimedia-cloud IRC channel on Freenode and sending a "!help ...." message to the channel explaining your issue.
