# l2-setup

## Setup Ansible

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

## Setup and Run Optimism

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

- 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 the following command.

  NOTE: By default, deployments are created in the `l2-setup/out` directory. To change this location, update the `l2_directory` variable in the [vars.yml](./vars.yml) file.

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

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

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

- 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 localhost, --connection=local run-optimism.yml --extra-vars='{"target_host" : "localhost", "existing_contracts_deployment":  true}' -kK --user $USER
    ```
