Update kubernetes templates with a docker image tag

Update Docker Tag

A simple utility to update the newly built docker image tag reference in your kubernetes deployments.

Usage:

First set the environment variable UPDATE_DOCKER_TAG_PATH to where your kubernetes templates are located. If this is not set, it will use the current directory.

export UPDATE_DOCKER_TAG_PATH=~/path/to/k8s/

Then run update-docker-tag <tag>, providing the image tag that you just built. If this is not specified, the latest docker tag will be found and used.

The command will output which files it has updated. The discovery of images to replace is quite good, but the patching is currently a bit basic, so it could potentially do mistakes.
