Insta-run Docker image

[faddat]

Summary

Includes:

• Genesis
• Seeds

Problem Definition

This reduces starting a node to:

docker run cosmos/gaia

Proposal

Create a Dockerfile that contains genesis & seeds are present in CMD.

May be more complex, because of init.

This isn't possible for the initial release of a chain upgrade. Until the chain is upgraded we dont know that the genesis is. it would be easier to write a way to fetch the genesis on init. This would only work once there is a genesis as well tho.

I have a demo of something like this, but never got around to completing it. I can look back at it in the coming days.

You are right.

I just ran into it while making the Dockerfile, came to note that in the repo, and saw your comment.

Closing this in favor of #678 #677

This was unfortunately an unworkable stopgap solution without changes to init, which would see genesis.json and the only options are to overwrite or not.
