• Provide a docker image for pcp - server and cli
• TODO: Provide docker-compose example setup
• TODO: Provide kubernetes chart example

@alekcz I would like to see Docker support for pcp.
I deploy and work with containers and I'm sure a lot of other people would deploy it like this as well.

This is a work in progress and feedback is welcomed.

[alekcz]

Thanks for this. I'll have a looksee this evening

[ieugen]

Thanks.

I'll have some questions & suggestions once I start using the PCP container.
I did not have time to finish it.

Can we avoid the utility for docker deployment?
Docker is designed to run a single processes.
It can run multiple processes but I think we can avoid that for this kind of use cases.

WDYT?

I've added instructions on how to build and also work with the image to deploy a website.
Docker container can be used for local development.

I think so. In the next release I want to be able to add the passphrase via HTTP request.
That way we end up with 2 docker images. One for the CLI for developers to use. And the second image is for deployment to the server. Does that make sense?

Depending on the size it could be the same image - to keep things simple.

This sounds strange - but I'm not familiar with pcp inner working.
Why would I need a passphrase? Is there a publish/upload step involved?
If so, then a token passed via header could be the solution.
I would go with Authorization: Bearer xxxx, where xxx is an opaque string - that could be a token to be decoded in more advanced implementations.
