Use Replicated Ship to generate the base and overlays
from the kubercoins GitHub repo.
The namespaces chapter has been slightly tweaked so
that we can use it for either Helm or Kustomize demo.
This is a new thing in Kubernetes 1.14. Added some details
about it (TL,DR it helps with cluster scalability but you
don't even have to know/care about it).
When following all the instructions, the Helm Chart that
we create is buggy, and the app shows up but with a zero
hash rate. This explains why, and how to fix it.
Fixes#432
We show how to change namespace by creating a new context, then
switching to the new context. It works, but it is very cumbersome.
Instead, let's just update the current context, and give some
details about when it's better to update the current context, and
when it is better to use different contexts and hop between them.
This was discussed and agreed in #246. It will probably break a few
outstanding PRs as well as a few external links but it's for the
better good long term.
