nitro-node demo

Setup

Fixturenet eth stack

  • Clone the stack repo:

    laconic-so fetch-stack git.vdb.to/cerc-io/fixturenet-eth-stacks --pull

  • Clone required repositories:

    laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth setup-repositories --pull

# If this throws an error as a result of being already checked out to a branch/tag in a repo, remove all repositories from that stack and re-run the command
# The repositories are located in $HOME/cerc by default

  • Build the container images:

    # Remove any older foundry image with `latest` tag
docker rmi ghcr.io/foundry-rs/foundry:latest

laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth build-containers --force-rebuild

# If errors are thrown during build, old images used by this stack would have to be deleted

    • NOTE: this will take >10 mins depending on the specs of your machine, and requires 16GB of memory or greater.

    • Remove any dangling Docker images (to clear up space):

      docker image prune

  • Create spec files for deployment, which will map the stack's ports and volumes to the host:

    laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy init --output fixturenet-eth-spec.yml

  • Configure ports:

    • fixturenet-eth-spec.yml

      ...
network:
  ports:
    fixturenet-eth-bootnode-geth:
      - '9898:9898'
      - '30303'
    fixturenet-eth-geth-1:
      - '8545:8545'
      - '8546:8546'
      - '40000'
      - '6060'
    fixturenet-eth-lighthouse-1:
      - '8001'
...

  • Create deployments: Once you've made any needed changes to the spec files, create deployments from them:

    laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy create --spec-file fixturenet-eth-spec.yml --deployment-dir fixturenet-eth-deployment

  • Env configuration:

    cat <<EOF > fixturenet-eth-deployment/config.env
CERC_ALLOW_UNPROTECTED_TXS=true
EOF

Go-nitro

  • Clone the stack repo:

    laconic-so fetch-stack git.vdb.to/cerc-io/nitro-stack --git-ssh --pull

  • Clone required repositories:

    laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-node setup-repositories --git-ssh --pull

  • Build the container images:

    laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-node build-containers --force-rebuild

Run

  • Start fixturenet-eth stack: (run steps in directory where the stack deployments had been created)

    • Start fixturenet-eth-deployment deployment:

      laconic-so deployment --dir fixturenet-eth-deployment start

      • Check status of L1

        • Run status check:

          laconic-so deployment --dir fixturenet-eth-deployment exec fixturenet-eth-bootnode-lighthouse "/scripts/status-internal.sh"

        • Check geth logs to ensure that new blocks are getting created

          laconic-so deployment --dir fixturenet-eth-deployment logs -f fixturenet-eth-geth-1

  • Deploy nitro contracts

    • Create a deployment spec-file for nitro contract:

      laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-contracts deploy init --output nitro-contracts-spec.yml --config "GETH_URL=http://host.docker.internal:8545,GETH_DEPLOYER_PK=888814df89c4358d7ddb3fa4b0213e7331239a80e1f013eaa7b2deca2a41a218,TOKEN_NAME=LaconicNetworkToken,TOKEN_SYMBOL=LNT,INITIAL_TOKEN_SUPPLY=129600"

    • Create a deployment nitro-contracts from the spec file

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

    • Start nitro-contracts deployment:

      laconic-so deployment --dir nitro-contracts-deployment start

# Check the logs
laconic-so deployment --dir nitro-contracts-deployment logs nitro-contracts -f

    • Get the deployed nitro contract addresses

       # Nitro contract addresses
 export NA_ADDRESS=$(laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.NitroAdjudicator.address' /app/deployment/nitro-addresses.json")

    • Export variables for token address

      export ASSET_ADDRESS="$(laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.Token.address' /app/deployment/nitro-addresses.json")"

    nitro-node:
      - 3007:3005
      - 4007:4005

Cleanup

  • Reset nitro-node deployments:

    • Stop nitro-node deployments and remove volumes:

    • Clear nitro-node and bridge deployments:

      # Run where deployments are created
sudo rm -rf alice-nitro-deployment
sudo rm -rf charlie-nitro-deployment

    • Stop deployment and remove volumes:

      # Run where deployments are created
laconic-so deployment --dir fixturenet-eth-deployment stop --delete-volumes

    • Clear deployments:
