#Run RChain network on a single machine with docker-compose

This repository allows to start small RChain network on local machine using docked-compose. It might be useful for those who wish to test changes to RNode, to get familiar with how network operates and how to configure and start private network. The behaviour is equal to normal network with each node having dedicated machine.

By default shard of 3 nodes is created, connected with the virtual network rchain-net. Each node exposes API ports via docker port mapping. Please see corresponding .yml file ports section to know exact port numbers.

Initially network state is clean. Once shard is started, nodes will perform genesis ceremony and create genesis block. This takes some time, but after that network can be stopped and started much faster. To clean the state of the network and start with the new genesis block, clear or remove data folder.

#Initial network data

The following data has to be downloaded first: Rchain-docker-cluster

List of publick keys of validators bonded in genesis block (bonds file): [./genesis/bonds.txt]

REV balances in genesis block (wallets file): [./genesis/wallets.txt]

Private keys and REV addresses for public keys in bonds file (format PublicKeyHex, PrivateKeyHex, RevAddress.): [./resources/keys.txt].

Configuration files for network nodes: [./conf]

#External Resource

1. RChain
2. PyRChain
3. Rchain-docker-cluster

#Dependencies

1. docker >=17.09.0
2. docker-compose >=1.17.0

#Start Network

Start a network of 3 nodes: containers rnode.bootstrap, rnode.validator1 and rnode.validator2

$ docker-compose -f ./shard.yml up

To start only a standalone node (container rnode.bootstrap)

$ docker-compose -f ./standalone.yml up

#[OPTIONAL] Enable automatic block creation

Make sure shard is up and running and all nodes printed Making a transition to Running state., which means Casper instance is ready to accept connections.

$ docker-compose -f ./propose.yml up

#[OPTIONAL] Start an observer node

Observer nodes are same as validators but started without private key provided, so they cannot sign and propose blocks. Such instances allow execution of so-called exploratory deploys to query the state of the DAG.

$ docker-compose -f ./read-only.yml up
