# 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
```
