Migrate to Kubernetes

[danmichaelo]

See https://wikitech.wikimedia.org/wiki/Help:Toolforge/Kubernetes and list of docker images

We cannot use the php5.6 image directly because it lacks ddjvu (from djvulibre-bin) and jpegtran (from libjpeg-progs)

Perhaps we can create a new iamge that extends the php5.6. image?

Reponse from irc was that it's currently not possible to create custom images. And since the djvulibre-bin and libjpeg-progs are quite specialized, I don't think it's a good idea to try having them added to the php5.6 image. So I'll wait with this until the Kubernetes strategy develops a bit further.
