Setup Ansible

To get started, follow the installation guide to setup ansible on your machine

Setup Remote Hosts

To run the playbook on a remote machine, follow these steps:

  • In the nitro-contracts-setup directory, create a new file named hosts.ini:

    cp ../example-hosts.ini hosts.ini
    
  • Edit the hosts.ini file to run the playbook on a remote machine

    [nitro_host]
    <host_name> ansible_host=<TARGET_IP> ansible_user=<SSH_USER> ansible_ssh_common_args='-o ForwardAgent=yes'
    
    • Replace <host_name> with the alias of your choice.
    • Replace <TARGET_IP> with the IP address or hostname of the target machine.
    • Replace <SSH_USER> with the SSH username (e.g., dev, ubuntu).
  • Verify that you are able to connect to the host using the following command

    ansible all -m ping -i hosts.ini -k
    
    # Expected output:
    
    # <host_name> | SUCCESS => {
    #  "ansible_facts": {
    #      "discovered_interpreter_python": "/usr/bin/python3.10"
    #  },
    #  "changed": false,
    #  "ping": "pong"
    # }
    

Deploy Nitro Contracts

The following commands have to be executed in nitro-contracts-setup directory

  • Copy the contract-vars-example.yml vars file

    cp contract-vars-example.yml contract-vars.yml
    
  • Edit contract-vars.yml and fill in the following values

    # L1 RPC endpoint
    geth_url: ""
    
    # L1 chain ID
    geth_chain_id: ""
    
    # Private key for a funded account on L1 to use for contracts deployment on L1
    geth_deployer_pk: ""
    
    # Custom L1 token to be deployed
    token_name: "LaconicNetworkToken"
    token_symbol: "LNT"
    intial_token_supply: "129600"
    
  • To deploy the L1 nitro contracts, execute the deploy-contracts.yml Ansible playbook by running one of the following commands:

    • For local deployment, specify the "target_host": localhost in the --extra-vars parameter:

      LANG=en_US.utf8 ansible-playbook deploy-contracts.yml --extra-vars='{ "target_host": "localhost"}' --user $USER -kK
      
    • For remote deployment, provide an inventory and specify the "target_host": nitro_host in the --extra-vars parameter:

      LANG=en_US.utf8 ansible-playbook -i ./hosts.ini deploy-contracts.yml --extra-vars='{ "target_host": "nitro_host"}' --user $USER -kK
      

    NOTE: By default, deployments are created in the nitro-contracts-setup/out directory. To change this location, update the nitro_directory variable in the setup-vars.yml file.

    • For skipping container build, run with "skip_container_build" : true in the --extra-vars parameter:

      LANG=en_US.utf8 ansible-playbook -i ./hosts.ini deploy-contracts.yml --extra-vars='{ "target_host": "localhost", "skip_container_build": true }' --user $USER -kK
      

Check Deployment Status

  • Run the following command in the directory where the nitro-contracts-deployment is created:

    • Check logs for deployments:

      # Check the L2 nitro contract deployment logs
      laconic-so deployment --dir nitro-contracts-deployment logs l2-nitro-contracts -f
      

Get Contract Addresses

  • Run the following commands in the directory where the deployments are created:

    • Get addresses of L1 nitro contracts:

      laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "cat /app/deployment/nitro-addresses.json"
