# nitro-bridge-demo-setup

## Setup Ansible

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

## Nitro Bridge Demo

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

- To set up the Nitro Bridge Demo, execute the `run-bridge-demo.yml` Ansible playbook by running the following command:

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

  ```bash
  LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-bridge-demo.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_US.utf8 ansible-playbook -i localhost, --connection=local run-bridge-demo.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

### Reset Demo

- Run the following command to reset demo:

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

  - Deployments are stopped
  - Nitro nodes deployment data are removed
  - Deployments are started again

- Steps from [Demo](https://git.vdb.to/cerc-io/nitro-stack/src/branch/main/nitro-bridge-demo.md#demo) can be run again

### Cleanup

- To stop all deployments, run the `stop-deployments.yml` playbook in the `nitro-stack-demo` directory:

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

- If you also want to remove the deployments, set `"remove_deployment_dir" : true` in the `--extra-vars` parameter when running the playbook:

  ```bash
  LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local stop-deployments.yml --extra-vars='{"target_host" : "localhost", "remove_deployment_dir" : true}' -K --user $USER
  ```
