# Go-nitro

## Setup

- Clone the stack repo

  ```bash
  laconic-so fetch-stack git.vdb.to/cerc-io/nitro-stack
  ```

- Clone required repositories

  ```bash
  laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-node setup-repositories
  ```

  Note: Replace path to nitro stack with actual path

- Build the container image

  ```bash
  laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-node build-containers
  ```

## Create a deployment

- Create a spec file

  ```bash
  laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-node deploy init --output nitro-node-spec.yml
  ```

- TODO: Edit `network` in the spec file to map container ports to host ports as required:

  ```bash
  network:
  ports:
    go-nitro:
     - 3006:3006
     - 4006:4006
     - 5006:5006
  ```

- Create deployment

  ```bash
  laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-node deploy create --spec-file nitro-node-spec.yml --deployment-dir nitro-node-deployment
  ```

## Configuration

- Inside the `nitro-node-deployment` deployment directory, open `config.env` file and set following env variables:

  ```bash
  # URL endpoint of the chain (Example: ws://host.docker.internal:8545)
  CERC_NITRO_CHAIN_URL=

  # Private key of account to be used by Nitro node (derived address is used as Nitro address)
  CERC_NITRO_PK=

  # Private key of the account on chain that is used for funding channels in Nitro node
  CERC_NITRO_CHAIN_PK=

  # Port to be used by P2P message service (Example: 3009)
  CERC_NITRO_MSG_PORT=

  # Port to be used by RPC server (Example: 4009)
  CERC_NITRO_RPC_PORT=4009

  # Optional
  # Contract addresses of NitroAdjudicator, VirtualPaymentApp and ConsensusApp
  # TODO: Contracts are deployed if addresses are not set
  CERC_NA_ADDRESS=
  CERC_VPA_ADDRESS=
  CERC_CA_ADDRESS=
  ```

## Start the deployment

```bash
laconic-so deployment --dir nitro-node-deployment start
```
