# Centralized Configuration via Gitea - Implementation Guide
|
||||
|
||||
**Date**: April 25, 2026
|
||||
**Goal**: Manage all VM configurations from a single Gitea repository
|
||||
**Result**: Zero per-VM configuration needed, all configs auto-fetched at startup
|
||||
|
||||
---
|
||||
|
||||
## 🎯 What This Achieves
|
||||
|
||||
Instead of managing configs on each VM:
|
||||
```
|
||||
OLD (Per-VM):
|
||||
VM1: nano ~/.opencode/config.json
|
||||
VM2: nano ~/.opencode/config.json
|
||||
VM3: nano ~/.opencode/config.json
|
||||
...repeat for every VM
|
||||
```
|
||||
|
||||
With centralized Gitea:
|
||||
```
|
||||
NEW (Single location):
|
||||
Gitea repo: edit opencode/config.json once
|
||||
All VMs: automatically pull latest on startup
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📋 Implementation Steps
|
||||
|
||||
### Step 1: Create the Gitea Repository (2 minutes)
|
||||
|
||||
1. Go to: **http://192.168.88.200:3000**
|
||||
2. Click **+** (top right) → **New Repository**
|
||||
3. Fill in:
|
||||
- **Repository name**: `homelab-configs`
|
||||
- **Description**: "Centralized configuration for all homelab VMs"
|
||||
- **Visibility**: Public (or Private if you prefer)
|
||||
4. Click **Create Repository**
|
||||
|
||||
### Step 2: Prepare and Push Configuration Files (5 minutes)
|
||||
|
||||
Run the setup script:
|
||||
|
||||
```bash
|
||||
bash /home/jgitta/Documents/Claude/Projects/Homelab\ Infrastructure/gitea-centralized-setup.sh
|
||||
```
|
||||
|
||||
This will:
|
||||
1. ✅ Create local git repository with all configs
|
||||
2. ✅ Show you the push commands to run
|
||||
3. ✅ Display next steps
|
||||
|
||||
**OR manually:**
|
||||
|
||||
```bash
|
||||
# Create and commit configs locally
|
||||
cd ~/homelab-configs
|
||||
git init
|
||||
git config user.name "jgitta"
|
||||
git config user.email "jgitta@jgitta.com"
|
||||
|
||||
# Add files (see script for structure)
|
||||
git add .
|
||||
git commit -m "Initial homelab-configs setup"
|
||||
|
||||
# Add remote and push
|
||||
git remote add origin http://192.168.88.200:3000/jgitta/homelab-configs.git
|
||||
git branch -M main
|
||||
git push -u origin main
|
||||
```
|
||||
|
||||
### Step 3: Update Nextcloud Docker-Compose (5 minutes)
|
||||
|
||||
SSH to Nextcloud VM:
|
||||
```bash
|
||||
ssh jgitta@192.168.88.62
|
||||
```
|
||||
|
||||
Find the docker-compose.yml file (likely in `/home/jgitta/docker` or similar):
|
||||
```bash
|
||||
cd /path/to/docker-compose
|
||||
```
|
||||
|
||||
Edit the OpenCode service to pull configs from Gitea. Use the template from:
|
||||
**`nextcloud-docker-compose-update.yml`**
|
||||
|
||||
Or update your existing docker-compose by adding this to the `opencode` service:
|
||||
|
||||
```yaml
|
||||
entrypoint: /bin/sh
|
||||
command: |
|
||||
-c "
|
||||
mkdir -p /tmp/homelab-configs
|
||||
git clone http://192.168.88.200:3000/jgitta/homelab-configs.git /tmp/homelab-configs || true
|
||||
mkdir -p /root/.opencode
|
||||
cp /tmp/homelab-configs/opencode/config.json /root/.opencode/config.json
|
||||
exec opencode
|
||||
"
|
||||
```
|
||||
|
||||
### Step 4: Restart OpenCode Service (2 minutes)
|
||||
|
||||
```bash
|
||||
cd /path/to/docker-compose
|
||||
|
||||
# Stop and remove
|
||||
docker-compose down
|
||||
|
||||
# Start with new config
|
||||
docker-compose up -d opencode
|
||||
|
||||
# Check logs
|
||||
docker-compose logs -f opencode
|
||||
```
|
||||
|
||||
You should see:
|
||||
```
|
||||
🔄 Fetching configuration from Gitea...
|
||||
✅ Configuration fetched successfully
|
||||
✅ OpenCode config loaded from Gitea
|
||||
🚀 Starting OpenCode...
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔄 Ongoing Management
|
||||
|
||||
### To Update OpenCode Config for All VMs
|
||||
|
||||
```bash
|
||||
# Clone the repo (or update if you have it)
|
||||
git clone http://192.168.88.200:3000/jgitta/homelab-configs.git
|
||||
cd homelab-configs
|
||||
|
||||
# Edit the config
|
||||
nano opencode/config.json
|
||||
|
||||
# Commit and push
|
||||
git add opencode/config.json
|
||||
git commit -m "Switch to gpt-4o-mini for faster responses"
|
||||
git push origin main
|
||||
```
|
||||
|
||||
**Next time OpenCode restarts**, it automatically gets the latest config!
|
||||
|
||||
### Adding More Services
|
||||
|
||||
Same pattern for any other service:
|
||||
|
||||
1. Create directory: `mkdir jellyfin`
|
||||
2. Add config: `cp ~/jellyfin/config.yml jellyfin/`
|
||||
3. Update that service's docker-compose to fetch from Gitea
|
||||
4. Commit and push

|
||||
## ✅ Verification
|
||||
|
||||
### Check if Repository Created:
|
||||
```bash
|
||||
curl http://192.168.88.200:3000/api/v1/repos/jgitta/homelab-configs \
|
||||
2>/dev/null | jq '.name'
|
||||
# Should output: homelab-configs
|
||||
```
|
||||
|
||||
### Check if Configs Are Accessible:
|
||||
```bash
|
||||
curl http://192.168.88.200:3000/jgitta/homelab-configs/raw/branch/main/opencode/config.json \
|
||||
2>/dev/null | jq '.apiBase'
|
||||
# Should output: "http://192.168.88.27:4000"
|
||||
```
|
||||
|
||||
### Check if OpenCode Pulled Config:
|
||||
```bash
|
||||
# SSH to Nextcloud
|
||||
ssh jgitta@192.168.88.62
|
||||
|
||||
# Check the config file
|
||||
cat ~/.opencode/config.json | jq '.'
|
||||
# Should show the config from Gitea
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🎯 Key Benefits Achieved
|
||||
|
||||
| Before | After |
|
||||
|--------|-------|
|
||||
| Configs on each VM | Single Gitea repo |
|
||||
| Manual edits per VM | One edit, all VMs update |
|
||||
| No version control | Full git history |
|
||||
| Hard to rollback | `git revert` to any point |
|
||||
| Config drift | Single source of truth |
|
||||
|
||||
---
|
||||
|
||||
## 🔐 Security Considerations
|
||||
|
||||
- **API Keys**: Currently in plaintext in `opencode/config.json`
|
||||
- For production: Use `.env` file not committed to git
|
||||
- Or: Use Docker secrets
|
||||
- Or: Fetch from secure vault
|
||||
|
||||
- **Repository Privacy**:
|
||||
- Set repo to Private if exposing internal IPs concerns you
|
||||
- Current setup is fine for internal network only
|
||||
|
||||
- **Git Clone Access**:
|
||||
- Currently HTTP (works on internal network)
|
||||
- Can use SSH if configured with deploy keys
|
||||

|
||||
## 📝 Common Tasks
|
||||
|
||||
### Change Model for All VMs
|
||||
```bash
|
||||
cd homelab-configs
|
||||
nano opencode/config.json
|
||||
# Change: "model": "gpt-4o" → "model": "claude-3.5-sonnet"
|
||||
git add opencode/config.json
|
||||
git commit -m "Switch model to claude-3.5-sonnet"
|
||||
git push origin main
|
||||
# Next OpenCode restart gets new model
|
||||
```
|
||||
|
||||
### Add New Service Config
|
||||
```bash
|
||||
mkdir -p myservice
|
||||
cat > myservice/config.json << 'EOF'
|
||||
{
|
||||
"apiEndpoint": "http://192.168.88.27:4000",
|
||||
"key": "litellm-local-key-change-in-production"
|
||||
}
|
||||
EOF
|
||||
git add myservice/
|
||||
git commit -m "Add myservice configuration"
|
||||
git push origin main
|
||||
```
|
||||
|
||||
### Check Config History
|
||||
```bash
|
||||
git log --oneline opencode/config.json
|
||||
# Shows every change made to OpenCode config
|
||||
```
|
||||
|
||||
### Revert to Previous Config
|
||||
```bash
|
||||
# Find the commit you want to revert to
|
||||
git log --oneline opencode/config.json
|
||||
|
||||
# Revert to that commit
|
||||
git revert <commit-hash>
|
||||
git push origin main
|
||||
|
||||
# Next restart: VMs get the old config back
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚨 Troubleshooting
|
||||
|
||||
### "Configuration fetched successfully" but config not applied
|
||||
- Check docker-compose volumes are mounted correctly
|
||||
- Verify `/root/.opencode/config.json` exists in container:
|
||||
```bash
|
||||
docker exec opencode cat /root/.opencode/config.json | jq '.'
|
||||
```
|
||||
|
||||
### "Could not fetch configs from Gitea"
|
||||
- Check network access: `curl http://192.168.88.200:3000/`
|
||||
- Verify Gitea repo exists and is public (or accessible)
|
||||
- Check docker-compose logs: `docker-compose logs opencode`
|
||||
|
||||
### Changes pushed but not pulled by VM
|
||||
- Restart the container: `docker-compose restart opencode`
|
||||
- Containers only pull config at startup
|
||||
|
||||
### "apiBase connection refused"
|
||||
- Verify LiteLLM is running: `curl http://192.168.88.27:4000/models`
|
||||
- Check docker network: containers need network access to docker-server

|
||||
|
||||
---
|
||||
|
||||
## 🔄 Switching Models
|
||||
|
||||
### Quick Switch (Edit Config)
|
||||
|
||||
```bash
|
||||
ssh jgitta@192.168.88.62
|
||||
|
||||
# Change model in config
|
||||
sed -i 's/"model": "gpt-4o"/"model": "claude-3.5-sonnet"/' ~/.opencode/config.json
|
||||
|
||||
# Verify
|
||||
cat ~/.opencode/config.json | jq '.model'
|
||||
```
|
||||
|
||||
### Via Gitea (Centralized)
|
||||
|
||||
Once you set up the Gitea integration:
|
||||
|
||||
1. Edit in Gitea: `opencode/config.json`
|
||||
2. Change model line
|
||||
3. Push: `git push origin main`
|
||||
4. Restart OpenCode to pull latest
|
||||
|
||||

|
||||
|
||||
## ⚠️ Current Limitation
|
||||
|
||||
**API Keys**: Currently using **placeholder keys**
|
||||
|
||||
```
|
||||
OPENAI_API_KEY=sk-your-actual-openai-key-here
|
||||
ANTHROPIC_API_KEY=sk-ant-your-actual-claude-key-here
|
||||
GOOGLE_API_KEY=your-actual-google-gemini-api-key-here
|
||||
```
|
||||
|
||||
### To Enable Real API Access:
|
||||
|
||||
1. **Get real API keys** from:
|
||||
- OpenAI: https://platform.openai.com/api-keys
|
||||
- Anthropic: https://console.anthropic.com/
|
||||
- Google: https://ai.google.dev/
|
||||
|
||||
2. **Update LiteLLM on docker-server**:
|
||||
```bash
|
||||
ssh root@192.168.88.27
|
||||
cd /opt/litellm
|
||||
nano .env
|
||||
# Add real keys
|
||||
docker-compose restart
|
||||
```
|
||||
|
||||
3. **Test from OpenCode**:
|
||||
```bash
|
||||
# Will now work without 401 errors
|
||||
opencode
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🧪 Quick Test
|
||||
|
||||
```bash
|
||||
ssh jgitta@192.168.88.62
|
||||
|
||||
# Verify everything is ready
|
||||
echo "=== Config ===" && \
|
||||
cat ~/.opencode/config.json | jq '.model' && \
|
||||
echo "=== LiteLLM Access ===" && \
|
||||
curl -s http://192.168.88.27:4000/models \
|
||||
-H "Authorization: Bearer litellm-local-key-change-in-production" | jq '.data | length'
|
||||
|
||||
# Should show:
|
||||
# "gpt-4o"
|
||||
# 10
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📚 Related Setup
|
||||
|
||||
### Gitea Integration (Optional)
|
||||
|
||||
To make OpenCode pull config from Gitea automatically:
|
||||
|
||||
```yaml
|
||||
# In docker-compose.yml
|
||||
services:
|
||||
opencode:
|
||||
entrypoint: /bin/sh
|
||||
command: |
|
||||
-c "
|
||||
git clone http://192.168.88.200:3000/jgitta/homelab-configs.git /tmp/configs
|
||||
cp /tmp/configs/opencode/config.json ~/.opencode/config.json
|
||||
exec ~/.opencode/bin/opencode
|
||||
"
|
||||
```

## 🎯 Next Steps
|
||||
|
||||
1. **Start using OpenCode** with LiteLLM backend:
|
||||
```bash
|
||||
ssh jgitta@192.168.88.62
|
||||
cd ~/your-project
|
||||
~/.opencode/bin/opencode
|
||||
```
|
||||
|
||||
2. **Add real API keys** (optional, for full functionality):
|
||||
- Update `/opt/litellm/.env` on docker-server
|
||||
- Restart LiteLLM: `docker-compose restart`
|
||||
|
||||
3. **Setup Gitea integration** (optional, for centralized config):
|
||||
- Follow: `gitea-centralized-implementation.md`
|
||||
|
||||
4. **Monitor logs** (if needed):
|
||||
```bash
|
||||
# Real-time logs if running in foreground
|
||||
~/.opencode/bin/opencode --verbose
|
||||
```
