## 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-config.env`](./templates/configs/l2-config.env) and fill in the following values

  ```bash
  # L1 Chain ID
  CERC_L1_CHAIN_ID=

  # L1 RPC endpoint
  CERC_L1_RPC=

  # L1 RPC endpoint host or IP address
  CERC_L1_HOST=

  # L1 RPC endpoint port number
  CERC_L1_PORT=

  # L1 Beacon endpoint
  CERC_L1_BEACON=

  # Address of the funded account on L1
  # Used for optimism contracts deployment
  CERC_L1_ADDRESS=

  # Private key of the funded account on L1
  CERC_L1_PRIV_KEY=

  # Funding amount for Optimism Proposer account on L1 (default: 0.2 ether)
  CERC_PROPOSER_AMOUNT=

  # Amount to send the batcher on L2 (default: 0.1 ether)
  CERC_BATCHER_AMOUNT=
  ```

- 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 the [`vars.yml`](./vars.yml) with paths to required artifacts

  - Run the ansible playbook with `"existing_l1_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_l1_deployment":  true}' -kK --user $USER
    ```
