Setup Ansible

To get started, follow the installation guide to setup ansible on your machine

Run a nitro node

The following commands have to be executed in nitro-nodes-setup directory

Copy the nitro-vars-example.yml vars file

cp nitro-vars-example.yml nitro-vars.yml

Edit nitro-vars.yml and fill in the following values

# L1 WS endpoint
nitro_l1_chain_url: ""

# L2 WS endpoint
nitro_l2_chain_url: ""

# Private key for your nitro address
nitro_sc_pk: ""

# Private key of the account on chain that is used for funding channels in Nitro node
nitro_chain_pk: ""

# Contract address of NitroAdjudicator
na_address: ""

# Contract address of VirtualPaymentApp
vpa_address: ""

# Contract address of ConsensusApp
ca_address: ""

# Address of the bridge node
bridge_contract_address: ""

# Multiaddr of the L1 bridge node
nitro_l1_bridge_multiaddr: ""

# Multiaddr of the L2 bridge node
nitro_l2_bridge_multiaddr: ""

# Multiaddr with publically accessible IP address / DNS for your L1 nitro node
# Example: "/ip4/192.168.x.y/tcp/3009"
# Example: "/dns4/example.com/tcp/3009"
nitro_l1_ext_multiaddr: ""

# Multiaddr with publically accessible IP address / DNS for your L2 nitro node
nitro_l2_ext_multiaddr: ""

To run a nitro node, execute the run-nitro-nodes.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-nodes.yml --extra-vars='{ "target_host": "localhost"}' -kK --user $USER
```
- 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-nodes.yml --extra-vars='{ "target_host": "localhost", "skip_container_build": true }' -kK --user $USER
```

Check Deployment Status

Run the following command in the directory where the deployments are created

Check L1 nitro node logs:

laconic-so deployment --dir l1-nitro-deployment logs nitro-node -f

Check L2 nitro node logs:

laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f
