# nitro-contracts-setup

## Setup Ansible

To get started, follow the [installation](../README.md#installation) guide to setup ansible on your machine

## Setup for Remote Host

To run the playbook on a remote host:

- Follow steps from [setup remote hosts](../README.md#setup-remote-hosts)

- Update / append the [`hosts.ini`](../hosts.ini) file for your remote host with `<deployment_host>` set as `nitro_host`

## Deploy Nitro Contracts

The following commands have to be executed in [`nitro-contracts-setup`](./) directory

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

  ```bash
  cp contract-vars-example.yml contract-vars.yml
  ```

- Edit [`contract-vars.yml`](./contract-vars.yml) and fill in the following values

  ```bash
  # 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:

    ```bash
    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:

    ```bash
    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](./setup-vars.yml) file.

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

    ```bash
    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:

    ```bash
    # 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:

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