# l2-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 `l2_host`

## Setup and Run Optimism

The following commands have to be executed in [`l2-setup`](./) directory

- Copy the `l2-vars-example.yml` vars file

  ```bash
  cp l2-vars-example.yml l2-vars.yml
  ```

- Edit [`l2-vars.yml`](./l2-vars.yml) with the required values

  ```bash
  # L1 chain ID
  l1_chain_id: ""

  # L1 RPC endpoint
  l1_rpc: ""

  # L1 RPC endpoint host or IP address
  l1_host: ""

  # L1 RPC endpoint port number
  l1_port: ""

  # L1 Beacon endpoint
  l1_beacon: ""

  # Address of the funded account on L1
  # Used for optimism contracts deployment
  l1_address: ""

  # Private key of the funded account on L1
  l1_priv_key: ""
  ```

- To setup and run L2, execute the `run-optimism.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 run-optimism.yml --extra-vars='{ "target_host": "localhost"}' -kK --user $USER
    ```

  - For remote deployment, provide an inventory and specify the `"target_host": l2_host` in the `--extra-vars` parameter:

    ```bash
    LANG=en_US.utf8 ansible-playbook -i ../hosts.ini run-optimism.yml --extra-vars='{ "target_host": "l2_host"}' -kK
    ```

    NOTE: By default, deployments are created in a `out` directory. To change this location, update the `l2_directory` variable in the [setup-vars.yml](./setup-vars.yml) file.

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

    ```bash
    LANG=en_US.utf8 ansible-playbook -i ../hosts.ini run-optimism.yml --extra-vars='{"target_host" : "l2_host", "skip_container_build": true}' -kK
    ```

- To run using existing contracts deployment

  - Update `artifact_path` in [`setup-vars.yml`](./setup-vars.yml) file with path to data directory of the existing deployment

  - Run the ansible playbook with `"existing_contracts_deployment": true` in the `--extra-vars` parameter:

    ```bash
    LANG=en_US.utf8 ansible-playbook -i ../hosts.ini run-optimism.yml --extra-vars='{"target_host" : "l2_host", "existing_contracts_deployment":  true}' -kK
    ```

## Check Deployment Status

- Run the following command in the directory where the optimism-deployment is created

  - Follow optimism contracts deployment logs:

    ```bash
    laconic-so deployment --dir optimism-deployment logs -f fixturenet-optimism-contracts
    ```

  - Check L2 logs:

    ```bash
    laconic-so deployment --dir optimism-deployment logs -f op-geth

    # Ensure new blocks are getting created
    ```
