## 💡 Pro Tips
1. **Use mistral model** - Best balance of speed and quality
2. **Monitor network latency** - `ping 100.x.x.x` should be < 50ms
3. **Keep Tailscale updated** - Better performance and security
4. **Run Ollama on GPU** - Much faster inference if available
5. **Use smaller models** - orca-mini for quick answers
## 🔐 Security Features
✅ **Encrypted Traffic** - All data encrypted via Tailscale
✅ **Private IPs** - Uses Tailscale private IP addresses (100.x.x.x)
✅ **No Public Exposure** - Ollama only accessible via Tailscale
✅ **Network Isolation** - Separate from public internet
✅ **End-to-End** - Secure connection from client to server

# CodeCompanion + Ollama + Tailscale Integration
## 🎯 What This Does
This setup allows you to use Ollama (local LLM) with CodeCompanion across your entire Tailscale network. You can:
- ✅ Use Ollama locally on your main machine
- ✅ Access Ollama from other machines via Tailscale (no local Ollama needed)
- ✅ Switch between Claude and Ollama models instantly
- ✅ Keep your configuration synced across machines
- ✅ Maintain privacy with encrypted Tailscale connections
## 🚀 Quick Start
### Step 1: On Your Ollama Server (Main Machine)
```bash
# Ensure Ollama listens on all interfaces
sudo systemctl edit ollama
# Add: Environment=\"OLLAMA_HOST=0.0.0.0:11434\"
# Save and exit
sudo systemctl restart ollama
# Pull a model
ollama pull mistral
# Find your Tailscale IP
tailscale ip -4
# Note this down (e.g., 100.123.45.67)
```
### Step 2: On Other Machines
Add to your shell config (`~/.zshrc`, `~/.bashrc`, etc.):
```bash
export OLLAMA_ENDPOINT=\"http://100.123.45.67:11434\"
```
Replace `100.123.45.67` with your actual Tailscale IP.
### Step 3: Use in Neovim
```vim
\" Press <leader>cll to chat with Ollama
\" Press <leader>cc to chat with Claude
\" Press <leader>ca to see all actions
```

| llama2 | 7B/13B | ⚡⚡ | ⭐⭐⭐ | General purpose |
| dolphin-mixtral | 8x7B | ⚡ | ⭐⭐⭐⭐ | Complex tasks |
## 🔧 Customization
### Change Default Model
Edit `lua/shelbybark/plugins/codecompanion.lua` line 40:
```lua
default = \"neural-chat\", -- Change this
```
### Add More Adapters
```lua
ollama_fast = function()
return require(\"codecompanion.adapters\").extend(\"ollama\", {
env = { url = os.getenv(\"OLLAMA_ENDPOINT\") or \"http://localhost:11434\" },
schema = { model = { default = \"orca-mini\" } },
})
end,
```
## 🧪 Testing
### Test 1: Ollama is Running
```bash
curl http://localhost:11434/api/tags
```
### Test 2: Network Access
```bash
export OLLAMA_ENDPOINT=\"http://100.x.x.x:11434\"
curl $OLLAMA_ENDPOINT/api/tags
```
### Test 3: Neovim Integration
```vim
:CodeCompanionChat ollama Toggle
\" Type a message and press Enter
```
## 🆘 Troubleshooting
### Connection Refused
```bash
# Check Ollama is running
ps aux | grep ollama
# Check it's listening on all interfaces
sudo netstat -tlnp | grep 11434
# Should show 0.0.0.0:11434, not 127.0.0.1:11434
```
### Model Not Found
```bash
# List available models
ollama list
# Pull the model
ollama pull mistral
```
### Can't Reach Remote Server
```bash
# Verify Tailscale
tailscale status
# Test connectivity
ping 100.x.x.x
curl http://100.x.x.x:11434/api/tags
```

## 🎓 How It Works
1. **Local Machine**: CodeCompanion connects to `http://localhost:11434`
2. **Remote Machine**: CodeCompanion connects to `http://100.x.x.x:11434` via Tailscale
3. **Tailscale**: Provides encrypted VPN tunnel between machines
4. **Ollama**: Runs on server, serves models to all connected machines
## ⚙️ System Requirements
### Ollama Server Machine
- 8GB+ RAM (for 7B models)
- Modern CPU or GPU
- Tailscale installed and running
- Ollama installed and running
### Client Machines
- Neovim 0.11.6+
- CodeCompanion plugin
- Tailscale installed and running
- No Ollama needed!
## 🔐 Security
- **Tailscale**: All traffic is encrypted end-to-end
- **Private IPs**: Uses Tailscale private IP addresses
- **No Port Exposure**: Ollama only accessible via Tailscale
- **Network Isolation**: Separate from public internet
## 💡 Tips
1. **Use smaller models** for faster responses (mistral, neural-chat)
2. **Monitor network latency** with `ping 100.x.x.x`
3. **Keep Tailscale updated** for best performance
4. **Run Ollama on GPU** if available for faster inference
5. **Use Claude for complex tasks**, Ollama for quick answers
## 🚨 Common Mistakes
❌ **Don't**: Forget to set `OLLAMA_HOST=0.0.0.0:11434` on server
✅ **Do**: Bind Ollama to all interfaces so it's accessible from network
❌ **Don't**: Use localhost IP (127.0.0.1) for remote access
✅ **Do**: Use Tailscale IP (100.x.x.x) for remote access
❌ **Don't**: Forget to export environment variable
✅ **Do**: Add to shell config and reload shell

```
Save and exit, then:
```bash
sudo systemctl restart ollama
# Pull a model
ollama pull mistral
# Find your Tailscale IP
tailscale ip -4
# You'll see something like: 100.123.45.67
```
### Step 2: Configure Other Machines (2 min)
On each machine that needs to access Ollama:
```bash
# Add to ~/.zshrc (or ~/.bashrc)
echo 'export OLLAMA_ENDPOINT="http://100.123.45.67:11434"' >> ~/.zshrc
# Reload shell

# CodeCompanion + Ollama Integration Summary
## What Was Done
Your CodeCompanion configuration has been updated to support Ollama models alongside your existing Claude adapters. Here's what changed:
### 1. **Added Ollama Adapter** (`lua/shelbybark/plugins/codecompanion.lua`)
- Reads `OLLAMA_ENDPOINT` environment variable
- Defaults to `http://localhost:11434` if not set
- Uses `mistral` as the default model (configurable)
### 2. **Added Ollama Keymaps**
- `<leader>cll` - Toggle Ollama chat (normal and visual modes)
- Works alongside existing Claude keymaps
### 3. **Created Documentation**
- `docs/OLLAMA_SETUP.md` - Comprehensive setup guide
- `docs/OLLAMA_QUICK_SETUP.md` - Quick reference for other machines
- `docs/ollama_env_example.sh` - Shell configuration example
## How It Works
### On Your Main Machine (with Ollama)
```bash
# Ollama runs locally, CodeCompanion uses http://localhost:11434 by default
nvim
# Press <leader>cll to chat with Ollama
```
### On Other Machines (without Ollama)
```bash
# Set environment variable to your Ollama server's Tailscale IP
export OLLAMA_ENDPOINT="http://100.123.45.67:11434"
nvim
# Press <leader>cll to chat with Ollama via Tailscale
```
## Key Features
✅ **Network Access**: Access Ollama from any machine on your Tailscale network
✅ **Fallback Support**: Keep Claude as primary, use Ollama as alternative
✅ **Easy Switching**: Use keymaps to switch between models instantly
✅ **Environment-Based**: Configuration adapts to each machine automatically
✅ **No Code Changes**: Just set an environment variable on other machines
## Next Steps
### 1. **On Your Ollama Server Machine**
Ensure Ollama is exposed to the network:
```bash
# Check current Ollama binding
ps aux | grep ollama
# If needed, set it to listen on all interfaces
sudo systemctl edit ollama
# Add: Environment="OLLAMA_HOST=0.0.0.0:11434"
# Save and exit, then:
sudo systemctl restart ollama
# Find your Tailscale IP
tailscale ip -4
```
### 2. **On Other Machines**
Add to your shell config (`~/.zshrc`, `~/.bashrc`, etc.):
```bash
export OLLAMA_ENDPOINT="http://YOUR_TAILSCALE_IP:11434"
```
### 3. **Test It**
```bash
# Verify connection
curl http://YOUR_TAILSCALE_IP:11434/api/tags
# Start Neovim and press <leader>cll
nvim
```
## Configuration Details
### Ollama Adapter Settings
- **Location**: `lua/shelbybark/plugins/codecompanion.lua` (lines 35-45)
- **Default Model**: `mistral` (change to your preference)
- **Endpoint**: Read from `OLLAMA_ENDPOINT` env var
- **Fallback**: `http://localhost:11434`
### Available Models to Try
- `mistral` - Fast, good quality (recommended)
- `neural-chat` - Optimized for conversation
- `dolphin-mixtral` - Larger, higher quality
- `llama2` - General purpose
- `orca-mini` - Very fast, lightweight
Pull models with: `ollama pull <model-name>`
## Troubleshooting
### Connection Issues
```bash
# Test Ollama is running
curl http://localhost:11434/api/tags
# Test Tailscale connectivity
ping 100.x.x.x # Use your Tailscale IP
# Check Ollama is bound to network
sudo netstat -tlnp | grep 11434
```
### Model Issues
```bash
# List available models
curl http://localhost:11434/api/tags | jq '.models[].name'
# Pull a model
ollama pull mistral
```

# CodeCompanion + Ollama Setup Guide
This guide explains how to use Ollama with CodeCompanion across your network via Tailscale.
## Overview
Your CodeCompanion configuration now supports both Claude (via Anthropic API) and Ollama models. You can:
- Use Ollama locally on your main machine
- Access Ollama from other machines on your network via Tailscale
- Switch between Claude and Ollama models seamlessly
## Prerequisites
### On Your Ollama Server Machine
1. **Install Ollama** (if not already done)
```bash
curl -fsSL https://ollama.ai/install.sh | sh
```
2. **Start Ollama with network binding**
By default, Ollama only listens on `localhost:11434`. To access it from other machines, you need to expose it to your network:
```bash
# Option 1: Run Ollama with network binding (temporary)
OLLAMA_HOST=0.0.0.0:11434 ollama serve
# Option 2: Set it permanently in systemd (recommended)
sudo systemctl edit ollama
```
Add this to the systemd service file:
```ini
[Service]
Environment="OLLAMA_HOST=0.0.0.0:11434"
```
Then restart:
```bash
sudo systemctl restart ollama
```
3. **Pull a model** (if not already done)
```bash
ollama pull mistral
# Or try other models:
# ollama pull neural-chat
# ollama pull dolphin-mixtral
# ollama pull llama2
```
4. **Find your Tailscale IP**
```bash
tailscale ip -4
# Output example: 100.123.45.67
```
## Configuration
### On Your Main Machine (with Ollama)
**Default behavior:** The config will use `http://localhost:11434` automatically.
To override, set the environment variable:
```bash
export OLLAMA_ENDPOINT="http://localhost:11434"
```
### On Other Machines (without Ollama)
Set the `OLLAMA_ENDPOINT` environment variable to point to your Ollama server's Tailscale IP:
```bash
export OLLAMA_ENDPOINT="http://100.123.45.67:11434"
```
**Make it persistent** by adding to your shell config (`~/.zshrc`, `~/.bashrc`, etc.):
```bash
export OLLAMA_ENDPOINT="http://100.123.45.67:11434"
```
## Usage
### Keymaps
- **`<leader>cll`** - Toggle chat with Ollama (normal and visual modes)
- **`<leader>cc`** - Toggle chat with Claude Haiku (default)
- **`<leader>cs`** - Toggle chat with Claude Sonnet
- **`<leader>co`** - Toggle chat with Claude Opus
- **`<leader>ca`** - Show CodeCompanion actions
- **`<leader>cm`** - Show current model
### Switching Models
You can also use the `:CodeCompanionSwitchModel` command:
```vim
:CodeCompanionSwitchModel haiku
:CodeCompanionSwitchModel sonnet
:CodeCompanionSwitchModel opus
```
To add Ollama to this command, you would need to extend the configuration.
## Troubleshooting
### "Connection refused" error
**Problem:** You're getting connection errors when trying to use Ollama.
**Solutions:**
1. Verify Ollama is running: `curl http://localhost:11434/api/tags`
2. Check if it's bound to the network: `sudo netstat -tlnp | grep 11434`
3. Verify Tailscale connectivity: `ping 100.x.x.x` (use the Tailscale IP)
4. Check firewall: `sudo ufw status` (if using UFW)
### "Model not found" error
**Problem:** The model you specified doesn't exist on the Ollama server.
**Solution:**
1. List available models: `curl http://localhost:11434/api/tags`
2. Pull the model: `ollama pull mistral`
3. Update the default model in `lua/shelbybark/plugins/codecompanion.lua` if needed
### Slow responses
**Problem:** Responses are very slow.
**Causes & Solutions:**
1. **Network latency**: Tailscale adds minimal overhead, but check your network
2. **Model size**: Larger models (7B+) are slower. Try smaller models like `mistral` or `neural-chat`
3. **Server resources**: Check CPU/RAM on the Ollama server with `top` or `htop`
### Tailscale not connecting
**Problem:** Can't reach the Ollama server via Tailscale IP.
**Solutions:**
1. Verify Tailscale is running: `tailscale status`
2. Check both machines are on the same Tailscale network
3. Verify the Tailscale IP is correct: `tailscale ip -4`
4. Check firewall rules on the Ollama server
## Recommended Models for CodeCompanion
| Model | Size | Speed | Quality | Best For |
|-------|------|-------|---------|----------|
| mistral | 7B | Fast | Good | General coding |
| neural-chat | 7B | Fast | Good | Chat/conversation |
| dolphin-mixtral | 8x7B | Slower | Excellent | Complex tasks |
| llama2 | 7B/13B | Medium | Good | General purpose |
| orca-mini | 3B | Very Fast | Fair | Quick answers |
## Advanced Configuration
### Custom Model Selection
To change the default Ollama model, edit `lua/shelbybark/plugins/codecompanion.lua`:
```lua
schema = {
model = {
default = "neural-chat", -- Change this to your preferred model
},
},
```
### Multiple Ollama Servers
If you have multiple Ollama servers, you can create multiple adapters:
```lua
ollama_main = function()
return require("codecompanion.adapters").extend("ollama", {
env = { url = "http://100.123.45.67:11434" },
schema = { model = { default = "mistral" } },
})
end,
ollama_backup = function()
return require("codecompanion.adapters").extend("ollama", {
env = { url = "http://100.123.45.68:11434" },
schema = { model = { default = "neural-chat" } },
})
end,
```
Then add keymaps for each.
## Performance Tips
1. **Use smaller models** for faster responses (mistral, neural-chat)
2. **Run Ollama on a machine with good specs** (8GB+ RAM, modern CPU)
3. **Keep Tailscale updated** for best network performance
4. **Monitor network latency** with `ping` to your Ollama server
5. **Consider running Ollama on GPU** if available for faster inference

source ~/.zshrc
# For bash (~/.bashrc):
echo 'export OLLAMA_ENDPOINT="http://100.x.x.x:11434"' >> ~/.bashrc
source ~/.bashrc
# For fish (~/.config/fish/config.fish):
echo 'set -gx OLLAMA_ENDPOINT "http://100.x.x.x:11434"' >> ~/.config/fish/config.fish
source ~/.config/fish/config.fish
# Verify it's set
echo $OLLAMA_ENDPOINT
# Restart Neovim to pick up the new variable
```
---
### 6. Ollama Not Accessible from Network
**Symptoms:**
- Works on localhost
- Fails when connecting from another machine
- `curl http://100.x.x.x:11434/api/tags` fails
**Causes:**
- Ollama is only bound to localhost (127.0.0.1)
- Firewall is blocking port 11434
- Network connectivity issue
**Solutions:**
```bash
# Check what Ollama is bound to
sudo netstat -tlnp | grep ollama
# Should show 0.0.0.0:11434 or your IP, not 127.0.0.1:11434
# If bound to localhost only, fix it:
sudo systemctl edit ollama
# Add this line in the [Service] section:
# Environment="OLLAMA_HOST=0.0.0.0:11434"
# Save and restart
sudo systemctl restart ollama
# Verify it's now listening on all interfaces
sudo netstat -tlnp | grep ollama
# Check firewall
sudo ufw status
sudo ufw allow 11434/tcp
sudo ufw reload
# Test from another machine
curl http://100.x.x.x:11434/api/tags
```
---
### 7. Neovim CodeCompanion Not Recognizing Ollama
**Symptoms:**

### 9. Timeout Errors
**Error Message:**
```
Error: Request timeout
Connection timed out after 30 seconds
```
**Causes:**
- Model is taking too long to respond
- Network latency is too high
- Server is overloaded
**Solutions:**
```bash
# Check network latency
ping -c 5 100.x.x.x
# Acceptable: < 50ms
# Marginal: 50-100ms
# Poor: > 100ms
# Try a faster model
ollama pull orca-mini
# Check server load
ssh user@100.x.x.x
top
# Look for high CPU or memory usage
# Reduce concurrent requests
# Only run one CodeCompanion chat at a time
# Increase timeout in CodeCompanion (if supported)
# Check CodeCompanion documentation
```
---
### 10. Permission Denied Errors
**Error Message:**
```
Error: Permission denied
Cannot access /var/lib/ollama
```
**Causes:**
- Ollama service running as different user
- File permissions are incorrect
- SELinux or AppArmor restrictions
**Solutions:**
```bash
# Check Ollama service user
sudo systemctl show -p User ollama
# Fix permissions
sudo chown -R ollama:ollama /var/lib/ollama
sudo chmod -R 755 /var/lib/ollama
# Restart service
sudo systemctl restart ollama
# Check SELinux (if applicable)
getenforce
# If "Enforcing", may need to adjust policies
# Check AppArmor (if applicable)
sudo aa-status | grep ollama
```
