To run the nitro bridge, execute the run-nitro-bridge.yml Ansible playbook by running the following command.

NOTE: By default, deployments are created in the nitro-nodes-setup/out directory. To change this location, update the nitro_directory variable in the setup-vars.yml file.
```
LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-nitro-bridge.yml --extra-vars='{ "target_host": "localhost"}' --user $USER -kK
```
- For skipping container build, run with "skip_container_build" : true in the --extra-vars parameter:
```
LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-nitro-bridge.yml --extra-vars='{ "target_host": "localhost", "skip_container_build": true }' --user $USER -kK
```

Check Deployment Status

Run the following command in the directory where the bridge-deployment is created:

Check logs for deployments:

# Check the l2 nitro contract deployments
laconic-so deployment --dir bridge-deployment logs l2-nitro-contracts -f

# Check the logs, ensure that the node is running
laconic-so deployment --dir bridge-deployment logs nitro-bridge -f

Get Contract Addresses

Run the following commands in the directory where the deployments are created:

Get addresses of L1 nitro contracts:

laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "cat /app/deployment/nitro-addresses.json"

Get addresses of L2 nitro contracts:
