Dockerhub deployment webhook for Kubernetes

===========================================

This consists in a really tiny HTTP server meant to receive webhook

notifications from DockerHub once images are built on a given tag.

This little program will figure out if deployments (in the namespaces you

specify) use images that match this `repo/image:tag` combination and, if so,

will update the target deployment in a rolling update fashion using an dirty old

trick.

Important Note

--------------

You shouldn't push your releases on the same tag, and therefore shouldn't need

this script: in order to benefit from Kubernetes roll back features (`kubectl

rollout undo ...`) it's much better to tag images according to the hashtag of

the commit id they are built upon (or the release tag, or any identifier for

every release of your image, would it be a simple date).

Doing so simply makes it impossible to roll back to previous versions of your

container without rebuilding & repushing a former version of the code they're

built upon.

However, some people seem to use such a moving "release tag" on Docker cloud

so...  this might come in handy if you're moving to Kubernetes.
