# nitro-nodes-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 `nitro_host`
|
|
|
|
## Setup
|
|
|
|
The following commands have to be executed in [`nitro-nodes-setup`](./) directory
|
|
|
|
- Copy the `nitro-vars-example.yml` vars file
|
|
|
|
```bash
|
|
cp nitro-vars.example.yml nitro-vars.yml
|
|
```
|
|
|
|
- Edit [`nitro-vars.yml`](./nitro-vars.yml) and fill in the following values
|
|
|
|
```bash
|
|
# 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: ""
|
|
```
|
|
|
|
## Run Nitro Node
|
|
|
|
### On Local Host
|
|
|
|
- To run a nitro node, execute the `run-nitro-nodes.yml` Ansible playbook by running the following command:
|
|
|
|
```bash
|
|
LANG=en_US.utf8 ansible-playbook run-nitro-nodes.yml --extra-vars='{ "target_host": "localhost"}' --user $USER -kK
|
|
```
|
|
|
|
NOTE: By default, deployments are created in a `out` directory. To change this location, update the `nitro_directory` variable in the [setup-vars.yml](./setup-vars.yml) file
|
|
|
|
- For skipping container build, run with `"skip_container_build" : true` in the `--extra-vars` parameter:
|
|
|
|
```bash
|
|
LANG=en_US.utf8 ansible-playbook -i hosts.ini run-nitro-nodes.yml --extra-vars='{ "target_host": "nitro_host", "skip_container_build": true }' --user $USER -kK
|
|
```
|
|
|
|
### On Remote Host
|
|
|
|
To run the playbook on a remote host:
|
|
|
|
- Create a new `hosts.ini` file:
|
|
|
|
```bash
|
|
cp ../hosts.example.ini hosts.ini
|
|
```
|
|
|
|
- Edit the [`hosts.ini`](./hosts.ini) file to run the playbook on a remote machine:
|
|
|
|
```ini
|
|
[<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
|
|
|
|
```bash
|
|
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"
|
|
# }
|
|
```
|
|
|
|
- Copy and edit the [`nitro-vars.yml`](./nitro-vars.yml) file as described in the [local setup](./README.md#run-nitro-node-on-local-host) section
|
|
|
|
- Execute the `run-nitro-nodes.yml` Ansible playbook for remote deployment:
|
|
|
|
```bash
|
|
LANG=en_US.utf8 ansible-playbook -i hosts.ini run-nitro-nodes.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:
|
|
|
|
```bash
|
|
LANG=en_US.utf8 ansible-playbook -i hosts.ini run-nitro-nodes.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 deployments are created
|
|
|
|
- Check L1 nitro node logs:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l1-nitro-deployment logs nitro-node -f
|
|
```
|
|
|
|
- Check L2 nitro node logs:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f
|
|
```
