Setup Ansible

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

Setup

The following commands have to be executed in the nitro-contracts-setup directory:

Copy the contract-vars.example.yml vars file

cp contract-vars.example.yml contract-vars.yml

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

# L1 RPC endpoint
geth_url: ""

# L1 chain ID
geth_chain_id: ""

# Private key for a funded account on L1 to use for contracts deployment on L1
geth_deployer_pk: ""

# Custom L1 token to be deployed
token_name: "LaconicNetworkToken"
token_symbol: "LNT"
initial_token_supply: "129600"

Deploy Contracts

On Local Host

To deploy nitro contracts locally, execute the deploy-contracts.yml Ansible playbook:
```
LANG=en_US.utf8 ansible-playbook deploy-contracts.yml --extra-vars='{ "target_host": "localhost"}' --user $USER -kK
```
NOTE: By default, deployments are created in an out directory. To change this location, update the nitro_directory variable in the setup-vars.yml file

For skipping container build, set "skip_container_build" : true in the --extra-vars parameter:

LANG=en_US.utf8 ansible-playbook deploy-contracts.yml --extra-vars='{"target_host" : "localhost", "skip_container_build": true}' --user $USER -kK

On Remote Host

To run the playbook on a remote host:

Create a new hosts.ini file:
```
cp ../hosts.example.ini hosts.ini
```
Edit the hosts.ini file to run the playbook on a remote machine:
```
[<deployment_host>]
<host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
```
- Replace <deployment_host> with nitro_host
- Replace <host_name> with the alias of your choice
- Replace <target_ip> with the IP address or hostname of the target machine
- Replace <ssh_user> with the SSH username (e.g., dev, ubuntu)

Verify that you are able to connect to the host using the following command

ansible all -m ping -i hosts.ini -k

# Expected output:

# <host_name> | SUCCESS => {
#  "ansible_facts": {
#      "discovered_interpreter_python": "/usr/bin/python3.10"
#  },
#  "changed": false,
#  "ping": "pong"
# }

Execute the deploy-contracts.yml Ansible playbook for remote deployment:

LANG=en_US.utf8 ansible-playbook -i hosts.ini deploy-contracts.yml --extra-vars='{ "target_host": "nitro_host"}'  --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 hosts.ini deploy-contracts.yml --extra-vars='{ "target_host": "nitro_host", "skip_container_build": true }' --user $USER -kK

Check Deployment Status

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

Check logs for deployments:

# Check the L2 nitro contract deployment logs
laconic-so deployment --dir nitro-contracts-deployment logs l2-nitro-contracts -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"
