Chia Network w/ Docker

This makes using the Chia network very easy, especially via CLI as Chia have now moved to an electron app. Testing with beta-1.0b8-dev at time of writing.

Prerequisites

Build the docker image

docker build -t chia .

Set up ENV

Set up a .env file, see .env.example. You'll want a fast drive for tmp, and a big drive for final. Worst case, just use the same drive.

Config

An example config.yaml will be added soon, however here is a list of the modifications that need to be made.

• Replace 127.0.0.1 with the appropriate host. Since each process runs as a container at a unique hostname (the service name), we need to direct traffic to the correct host. This is generally replacing the key xxx_peer: 127.0.0.1 to xxx_peer: xxx, e.g. farmer_peer: farmer since the farmer will be available at the hostname farmer.
• Set start_rpc_server: false. We don't need the rpc server, as it is designed to allow interprocess communication when everything is all running and hidden, and to manage services / processes. We interact directly by running and stopping docker containers instead.
• Update plots.yml to change your local dir to the mounted dir, i.e. /plots-final/plot-knn-yyyy-mm-dd-hh-MM-xxxxxxxxxx.dat.

Running

Init

# Init your config
docker-compose run init

# Generate your keys
docker-compose run generate_keys

Plots

# Start Generating some Plots
docker-compose up -d create_plots
# Alternate invocation
docker-compose up -d -e PLOT_K=30 -e PLOT_N=10 create_plots

Farming

docker-compose up -d full_node
docker-compose up -d farmer
docker-compose up -d harvester

TODO

• config.yml with appropriate hosts and ports for running components internally

docker-compose.yml
