# Run nitro-nodes 

## Setup

- Follow the [installation guide](https://github.com/deep-stack/ops/blob/ag-run-l2/README.md#installation) to setup ansible on your machine

- Ensure laconic-so is installed 

  ```bash
  laconic-so version
  ```
  
- Clone the ops repo

  ```bash
  git clone git@github.com:deep-stack/ops.git
  cd ops
  git checkout ag-run-l2
  ```


## Run l1, l2 nitro nodes

- Navigate to the `vulcanize/nitro-node-setup` directory

  ```bash  
  cd vulcanize/nitro-node-setup
  ```

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

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

<!-- TODO: Provide nitro environment variables to user -->
- Edit [`nitro-vars.yml`](./nitro-vars.yml) and fill in the following values

  ```bash
  # URL endpoint of the L1 chain
  l1_nitro_chain_url: ""

  # URL endpoint of the L2 chain
  l2_nitro_chain_url: ""

  # Private key for your nitro address
  nitro_sc_pk: ""

  # Private key of the account on chain that is used for funding channels in Nitro node
  nitro_chain_pk: ""

  # Contract address of NitroAdjudicator
  na_address: ""

  # Contract address of VirtualPaymentApp
  vpa_address: ""

  # Contract address of ConsensusApp
  ca_address: ""

  # Contract address of bridge
  bridge_address: ""

  # IP address of the bridge node
  nitro_bridge_ip: ""

  # Publically accessible IP address of your nitro node
  nitro_node_ip: ""
  ```

- To run nitro nodes, execute the `run-nitro-node.yml` Ansible playbook by running the following command.

  NOTE: By default, deployments are created in the `nitro-node-setup/out` directory. If you need to change this location, you can update the `nitro_directory` variable in the [setup-vars.yml](./setup-vars.yml) file.

  ```bash
  LANG=en_IN.utf8 ansible-playbook -i localhost, --connection=local run-nitro-node.yml --extra-vars='{ "target_host": "localhost"}' --user $USER
  ```

  - If you want to skip building the containers, set `"skip_container_build" : true` in the `--extra-vars` parameter:

    ```bash
    LANG=en_IN.utf8 ansible-playbook -i localhost, --connection=local run-nitro-node.yml --extra-vars='{ "target_host": "localhost", "skip_container_build": true }' --user $USER
    ```

- Follow steps from [Demo](https://git.vdb.to/cerc-io/nitro-stack/src/branch/main/nitro-bridge-demo.md#demo) to create mirror channels on L2, create virtual channel and make payments
