Dockerfile does not copy genesis or app.toml during build

[no-no-genesis]

Summary of Bug

When we run

docker build .

and

docker run -it $image

it fails with the error

Error: set min gas price in app.toml or flag or env variable: Error in app.toml

While this makes some sense to lack a default value, changing the start command to

docker run -it $image /usr/bin/sommelier start --min-gas-prices 1 

fails with no genesis file available.

It's not obvious how to get the chain to sync with the Dockerfile provided, even using a testnet genesis file which doesn't require cosmovisor.

I copied files from my local machine in my Dockerfile as a fix but I'm not sure that should be the standard.

Hi @no-no-genesis, may I ask what this is for? We only use the dockerfile for our integration test setup, which sets the config files itself.
