| 1 | # Vole on Hetzner Cloud |
| 2 | |
| 3 | One server, configured on its first boot by a file you paste into the console. No |
| 4 | API token, nothing to install locally: a rendered file, a server, a firewall, and |
| 5 | one DNS record. |
| 6 | |
| 7 | ## What you need |
| 8 | |
| 9 | - A Hetzner Cloud account and a project. |
| 10 | - A DNS name, such as `forge.example.com`. |
| 11 | - Your SSH public key. |
| 12 | - The URL of a Vole `.deb` for `amd64` — or `arm64` on a CAX server type — from |
| 13 | [Vole's releases](https://rodent.software/vole/releases). |
| 14 | |
| 15 | ## Render the first-boot file |
| 16 | |
| 17 | From a clone of the Vole repository, on your own computer: |
| 18 | |
| 19 | ```sh |
| 20 | cd deploy/cloud-init |
| 21 | |
| 22 | HOSTNAME=forge.example.com \ |
| 23 | ADMIN_ACCOUNT=admin \ |
| 24 | ADMIN_EMAIL=you@example.com \ |
| 25 | ADMIN_SSH_KEY="$(cat ~/.ssh/id_ed25519.pub)" \ |
| 26 | VOLE_PACKAGE_URL=https://rodent.software/vole/releases/v0.2.0/artifacts/vole_0.2.0-1_amd64.deb \ |
| 27 | ./render.sh > user-data.yaml |
| 28 | ``` |
| 29 | |
| 30 | Open `user-data.yaml` before you paste it. It is the whole setup, and it is the |
| 31 | last chance to notice a wrong account name: names are permanent. |
| 32 | |
| 33 | ## Create the server |
| 34 | |
| 35 | In the Hetzner console, **Add Server**: |
| 36 | |
| 37 | | Field | What to choose | |
| 38 | |---|---| |
| 39 | | Location | wherever your team is | |
| 40 | | Image | Ubuntu 24.04 (Debian 13 works too) | |
| 41 | | Type | CX22 — 2 vCPU, 4 GB, 40 GB. Raise it if you expect big pushes or LFS | |
| 42 | | Networking | public IPv4 | |
| 43 | | SSH key | yours, the same one you put in the file | |
| 44 | | Backups | on. It is a snapshot, not a backup of the instance — see [Backups](README.md#backups-are-still-your-job) | |
| 45 | | **Cloud config** | paste the contents of `user-data.yaml` | |
| 46 | |
| 47 | Before or after creating it, add a **Firewall** in the same project and apply it to |
| 48 | the server. Hetzner leaves a new server open if you do not: |
| 49 | |
| 50 | | Direction | Protocol | Port | Source | |
| 51 | |---|---|---|---| |
| 52 | | in | tcp | 22 | your team's addresses, for shell access | |
| 53 | | in | tcp | 2222 | your team's addresses. This is Git over SSH, the write transport | |
| 54 | | in | tcp | 80 | anywhere, for the certificate challenge | |
| 55 | | in | tcp | 443 | anywhere | |
| 56 | | out | any | any | anywhere, so the server can fetch its package and certificate | |
| 57 | |
| 58 | Restricting 2222 to your team is the cheapest way to keep the write side private. |
| 59 | If you leave it open, Vole still authenticates every connection by key. |
| 60 | |
| 61 | ## Point the name at it |
| 62 | |
| 63 | Create an `A` record for `forge.example.com` pointing at the server's IPv4 |
| 64 | address. Vole cannot obtain a certificate for a name that does not resolve to it |
| 65 | yet, and it retries, so a record created a few minutes after the server is fine. |
| 66 | |
| 67 | ## Check it works |
| 68 | |
| 69 | Open `https://forge.example.com`. The first request may take a few seconds while |
| 70 | the certificate is issued; if it fails, wait a minute and reload. |
| 71 | |
| 72 | Issue a passkey for the admin account from your laptop: |
| 73 | |
| 74 | ```sh |
| 75 | vole admin --remote ssh://git@forge.example.com:2222 account invite admin |
| 76 | ``` |
| 77 | |
| 78 | Then create a repository, and clone it: |
| 79 | |
| 80 | ```sh |
| 81 | vole admin --remote ssh://git@forge.example.com:2222 repo create demo --owner admin |
| 82 | vole admin --remote ssh://git@forge.example.com:2222 acl set-default-role demo read |
| 83 | git clone ssh://git@forge.example.com:2222/demo.git |
| 84 | ``` |
| 85 | |
| 86 | ## Adding a CI runner |
| 87 | |
| 88 | Create a second server the same way, but give it the runner's file: |
| 89 | |
| 90 | ```sh |
| 91 | ./render.sh runner > runner-user-data.yaml # FORGE_HOST=forge.example.com and VOLE_PACKAGE_URL |
| 92 | ``` |
| 93 | |
| 94 | It needs no inbound ports except 22. It needs one more step per repository before |
| 95 | it takes work; see [CI runners](runner.md). |
| 96 | |
| 97 | ## The settings worth changing |
| 98 | |
| 99 | The values you pass to `render.sh`. Everything else has a working default. |
| 100 | |
| 101 | | Variable | Default | What it does | |
| 102 | |---|---|---| |
| 103 | | `HOSTNAME` | required | The name the instance answers on. It becomes `public_url`, and passkeys bind to it | |
| 104 | | `ADMIN_ACCOUNT` | required | The first account, made an instance admin. Permanent | |
| 105 | | `ADMIN_SSH_KEY` | required | That account's public key | |
| 106 | | `VOLE_PACKAGE_URL` | required | The `.deb` for the machine's architecture | |
| 107 | | `ADMIN_EMAIL` | empty | Contact address for the certificate authority | |
| 108 | | `INSTANCE_NAME` | `Vole` | What the landing page calls this forge | |
| 109 | | `TLS_MODE` | `acme` | `proxy` leaves TLS to a proxy you run, and serves plain HTTP on loopback | |
| 110 | |
| 111 | ## If something is not right |
| 112 | |
| 113 | - **The browser shows a certificate warning.** DNS is not answering with the |
| 114 | server's address yet, or ports 80 and 443 are blocked by the firewall. Check |
| 115 | `dig +short forge.example.com`, then `journalctl -u vole | grep -i acme`. |
| 116 | - **The server is up but the forge is not.** First-boot output is in |
| 117 | `/var/log/vole-first-boot.log`; the service log is `journalctl -u vole`. The |
| 118 | usual cause is a package URL that 404s or is for the other architecture. |
| 119 | - **Nothing listens on 2222.** The firewall is not applied to the server, or its |
| 120 | source addresses do not include where you are pushing from. |
| 121 | - **Pushing is refused.** `vole whoami --remote ssh://git@forge.example.com:2222` |
| 122 | says which account your key is; if it is not the one you expected, the key was |
| 123 | not the one in `user-data.yaml`. |
