Everything you need to set up a Hub.

How to use this repository

The master branch contains deployment scripts in the ./kernel directory, while the ./contracts directory contains the ChannelManager contract designed to work with the hub for local development.

Starting the hub

Prerequisites

tl;dr

Start the Hub. The Hub will use localhost:3000.
- Install dependencies: npm i
- Install Truffle: npm i -g truffle
- Install and run Ganache CLI: npm i -g ganache-cli and ganache-cli -m "candy maple cake sugar pudding cream honey rich smooth crumble sweet treat" -i 4447 -b 3
- Migrate contracts: truffle migrate --reset --network development
- Match CONTRACT_ADDRESS, ETH_NETWORK_ID, and HUB_ACCOUNT in kernel/deploy.prod.sh to your targeted blockchain.
- Deploy the Docker stack with npm run hub-start

Detailed Steps

For Ganache: Start Ganache on your host machine.

ganache-cli -m "candy maple cake sugar pudding cream honey rich smooth crumble sweet treat" -i 4447 -b 3

Migrate the contracts to your local blockchain.

truffle migrate --reset --network development

For Rinkeby/testnet: Start a node on your computer and migrate the contracts. Make sure to change the above mentioned variables to match your targeted blockchain.
Verify kernel/deploy.prod.sh to make sure the variables CONTRACT_ADDRESS, ETH_NETWORK_ID, and HUB_ACCOUNT match your targeted blockchain. If you are using Ganache with the above command, it will be set up for this by default.
Deploy the Docker stack.

npm run hub-start

Once the wake-up process completes, view the logs.

npm run logs-hub

npm run logs-chainsaw

If you can't see logs, try the following to further debug.

docker service ps --no-trunc connext_hub

docker service ps --no-trunc connext_chainsaw

Check that the hub is up by polling localhost:3000

curl http://localhost:3000
