||
```bash
|
||
mkdir -p /home/aetos/registry/auth
|

2. Set correct permissions:
|
||
|
||
```bash
|
||
chmod 644 /home/aetos/registry/auth/htpasswd

|
||
|
||
#### Ports
|
||
|
||
* **6002 → 3000** — Web UI.

|
||
|
||
#### Extra Config Required
|
||
|
||
1. Access Gitea at [https://git.aetoskia.com](https://git.aetoskia.com).
|
||
2. Log in as the **`aetos`** admin user (repository owner).
|
||
3. Verify Drone OAuth App is registered with:
|
||
|
||
```
|
||
Application Name: Drone CI
|
||
Redirect URI: https://drone.aetoskia.com/login
|
||
```
|
||
4. Confirm Gitea has these extra host mappings:
|
||
|
||
```
|
||
192.168.1.111 drone.aetoskia.com
|
||
```
|
||
|

|
||
|
||
### 🚀 **Drone Server**
|
||
|
||
Core CI/CD engine that connects to Gitea and manages build pipelines.
|
||
|
||
#### Ports
|
||
|
||
* **6003 → 80** — Drone web UI and API endpoint.
|
||
|
||
#### Mounts

|
||
* **DRONE_RPC_SECRET:** Shared secret for secure runner communication.
|
||
* **DRONE_SERVER_HOST / PROTO:** External access configuration.
|
||
|
||
#### Extra Config Required
|
||
|
||
1. Register the OAuth app in Gitea → Admin → Applications:
|
||
|
||
* Redirect URI: `https://drone.aetoskia.com/login`
|
||
2. Stop Drone and make admin user (if needed):
|
||
|
||
```bash
|
||
docker stop drone-server
|
||
sqlite3 /home/aetos/drone/database.sqlite "UPDATE users SET user_admin=1 WHERE user_login='aetos';"
|
||
docker start drone-server
|
||
```
|
||
3. Use admin token for CLI:
|
||
|
||
```bash
|
||
export DRONE_SERVER=https://drone.aetoskia.com
|
||
export DRONE_TOKEN=<admin_token>
|
||
```
|
||

||
```
|
||
|

|
||
### 🧮 **Drone Runner**
|
||
|
||
Executes pipeline steps on the Docker host using the Drone RPC secret.
|
||
|
||
#### Ports
|
||
|
||
* *(none)* — Internal runner; connects to Drone Server API via HTTPS.
|
||
|
||
#### Mounts
|
||
|
||
* `/var/run/docker.sock:/var/run/docker.sock` — Allows pipeline containers to spawn Docker builds.
|
||
|
||
#### Environment
|
||
|
||
* **DRONE_RPC_PROTO / HOST / SECRET:** Connects to Drone Server via shared key.
|
||
* **DRONE_RUNNER_CAPACITY:** Number of parallel jobs supported.
|
||
* **DRONE_RUNNER_NAME / OS / ARCH:** Runner identification.
|
||
* **DRONE_LOGS_DEBUG / TRACE:** Enables detailed logging for troubleshooting.
|
||
|
||
#### Extra Config Required
|
||
|
||
1. Ensure the RPC secret matches the one defined in `drone-server`.
|
||
2. Validate connectivity:
|
||
|
||
```bash
|
||
docker logs drone-runner
|
||
```
|
||
|
||
Look for:
|
||
|
||
```
|
||
successfully pinged the remote drone server
|
||
```
|
||
|
||

|
||
|
||
## 🧬 Network Integration
|
||
|
||
Ensure `/etc/hosts` on all relevant devices (Pi nodes, local dev systems) includes:
|
||
|
||
```
|
||
192.168.1.111 git.aetoskia.com
|
||
192.168.1.111 drone.aetoskia.com
|
||
192.168.1.111 dcr.aetoskia.com
|
||
```
|
||
|
||
---
|
||
|
||
## 🧠 Tips
|
||
|
||
* Always start containers with profile `private-pi` to avoid unnecessary public exposure:
|
||
|
||
```bash
|
||
docker compose --profile private-pi up -d
|
||
```
|
||
* Drone and Gitea must both trust the same SSL certificate chain under `/home/aetos/certs`.
|
||
* The `registry-ui` and `drone-runner` depend on hostname resolution between internal services, so avoid using raw IPs in environment variables.
