🌱 Radicle Cloud ☁️

This repository includes the operator and the contracts you need to become a service provider for Radicle seed nodes.

Contract

You can deploy ETH and ERC-20 based contracts located inside contract and then point your operator to your deployed contract. An example script is provided for you in deploy.sh which deploys EthRadicleCloud.sol to Arbitrum Rinkeby Testnet. You can change network by changing ETH_RPC_URL. You must have dapp.tools installed.

IMPORTANT: replace ETH_FROM with your own wallet and make sure the key can be found in your local keystore. If you want to import a private key, use:

$ geth account import /path/to/private-key

Finally, make CONTRACT_ADDRESS point to your own deployed contract in .env.operator.

Deploy Operator

You can deploy operator with Ansible after filling in your .env.operator, which you can sample from .env.sample.

SSH Key

Generate an SSH key for your operator, if you already don't have one, with:

$ ssh-keygen -t ed25519
Generating public/private ed25519 key pair.
Enter file in which to save the key (/home/user/.ssh/id_ed25519): cloud-operator
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in cloud-operator.
Your public key has been saved in cloud-operator.pub.
The key fingerprint is:
SHA256:... user@host
The key's randomart image is:
+--[ED25519 256]--+
|                 |
|                 |
|       ...       |
+----[SHA256]-----+

Upload the pub key to your cloud, e.g. Hetzner and add the name (HETNZER_SSH_NAME) to your .env.operator file.

Deploying

Make sure your private SSH key can be found locally in ~/.ssh/local_ssh_name and that LOCAL_SSH_PATH in .env.operator file matches:

# .env.operator (truncated)
LOCAL_SSH_PATH=~/.ssh/cloud-operator

Finally:

$ ansible-playbook ansible/deploy-operator.yml [email protected], --private-key=~/.ssh/key-to-server --extra-vars="local_ssh_name=cloud-operator db_name=radicle db_user=postgres db_password=postgres"
