Change examples to track the master branch

[krnowak]

Recently we have changed habitat-operator to use stateful sets instead of deployments. A part of the change was to update the rbac rules in examples/rbac/rbac.yml. But examples/rbac/habitat-operator.yml still points to a docker image that contains that handles deployments. So after applying the manifests in examples/rbac we are going to get permission errors because the old operator can't do anything with deployments anymore.

So I was wondering if we should use a latest tag in our examples and on every change in master branch, we should build the docker image and push it to the docker registry with latest tag.

That would likely require a new step in our release process - after a release is done, we change all the manifests in examples, so they use habitat/habitat-operator:latest.

Not sure if we should do the same for helm charts.

I'm not sure whether to put it in the project board.

Why not?

I basically thought that project board is a board of issues that we need to work on, and I feel that this issue is more or less a request for enhancement.

I think it belongs in the board, and it can be tagged with "enhancement".

To the point of the issue: I think the way we do it now is that we update the examples once we release a new version.

Basically, right now running the examples from the master branch is broken, because the operator is out of date.

after a release is done, we change all the manifests in examples, so they use habitat/habitat-operator:latest

I don't get this. With your change, there is nothing to change in the manifests, because they already use latest. What there is to do is push the docker tag latest.

I think it's a good idea btw.

When we do a release, I would like the examples to use the properly tagged docker images. And after we do git tag on the commit, we revert back to using latest. This is to have examples in the release tarball (or zip) to use properly tagged docker images, not latest.
