Create a new "empty backend" project

[bmonkman]

Originally the "zero-deployable-backend" project was supposed to be this but it sort of turned into the Go backend.
We should have a project which gives an example of how to make your current service Zero-ready by including just the CI, dockerfile, kubernetes stuff so we can let people easily take an existing project and bootstrap it into the Zero ecosystem.
The service that gets started can just run something like ncat -c 'echo "HTTP/1.1 200 OK\n\nHi from Zero ($(date))"' -k -l 8080

Hi @bmonkman , can you please create an empty repository so I can fork it and make it a pr? Do you also think that a simple empty frontend which use native Ajax to display the result from the backend would be useful?

Here my initial change edmondop@5a2d2f7 and my proposed names for the repos

@edmondo1984 Happy to do that! Here are the new repos:
https://github.com/commitdev/zero-backend-empty
https://github.com/commitdev/zero-frontend-empty

I would like to rename the existing modules, so I've created these new ones with the updated naming scheme.
And for the frontend yes I guess we could make a simple ajax call to the backend but I would say let's make sure it's as simple as possible. Ideally just a single HTML file. We don't want to distract people from the main point of these repos which is the stuff that you can copy into an existing project to make it easily compatible with Zero. (CI, Dockerfile, Kubernetes manifests)

Thanks!

I split the frontend part of this out into #430
