# Session Summary - Gitea Domain Configuration & SSH Fixes
|
||||||
|
**Date:** 2025-11-26
|
||||||
|
|
||||||
|
## Project Context
|
||||||
|
**Project:** Gitea Setup - Domain Configuration and SSH Key Setup Fixes
|
||||||
|
**System:** Homelab Git Server (git-repro LXC at 100.120.125.113)
|
||||||
|
**User:** pdm
|
||||||
|
**Focus:** Domain integration with Pangolin Tunnel, SSH agent persistence fixes
|
||||||
|
|
||||||
|
## Session Overview
|
||||||
|
Integrated Gitea with Pangolin Tunnel domain (git.pdmarf.co.uk), fixed SSH agent persistence issues in VPS setup guide, and ensured all documentation reflects correct configuration for both internal and external access.

|
## Session Accomplishments
|
||||||
|
|
||||||
|
### 1. Domain Integration with Pangolin Tunnel
|
||||||
|
- ✓ Initial attempt: Set ROOT_URL to HTTPS in Gitea config
|
||||||
|
- ✓ Identified protocol mismatch issue (HTTPS ROOT_URL but HTTP listening)
|
||||||
|
- ✓ Fixed configuration: Reverted to HTTP:3000 internally
|
||||||
|
- ✓ Pangolin Tunnel now properly routes https://git.pdmarf.co.uk → http://100.120.125.113:3000
|
||||||
|
- ✓ Verified Gitea listens on HTTP port 3000 (confirmed via ss/netstat)
|
||||||
|
|
||||||
|
### 2. Documentation Updates
|
||||||
|
- ✓ Updated HOW-TO-GUIDE.md with dual access methods:
|
||||||
|
- Internal IP: http://100.120.125.113:3000 (for VPS/local network)
|
||||||
|
- Domain: https://git.pdmarf.co.uk (via Pangolin Tunnel for external access)
|
||||||
|
- ✓ Added clarification notes about domain access
|
||||||
|
- ✓ Clone commands use internal IP (more reliable, works everywhere)
|
||||||
|
- ✓ Committed changes to Gitea repository
|
||||||
|
|
||||||
|
### 3. SSH Key Setup Fixes
|
||||||
|
- ✓ Reviewed VPS-SSH-KEY-SETUP.md from repository
|
||||||
|
- ✓ Identified Step 7 SSH agent persistence bug:
|
||||||
|
- **Problem:** Original code tried to append ssh-agent output to file
|
||||||
|
- **Symptom:** Agent would die on logout, requiring manual restart
|
||||||
|
- ✓ Rewrote Step 7 with robust, tested solution:
|
||||||
|
- Detects existing running agents
|
||||||
|
- Persists socket location across shell sessions
|
||||||
|
- Auto-loads SSH key on new terminals
|
||||||
|
- Works across multiple terminal windows
|
||||||
|
- Includes working fallback if complexity fails
|
||||||
|
- ✓ Added comprehensive troubleshooting section
|
||||||
|
- ✓ Committed updated guide to Gitea
|
||||||
|
|
||||||
|
### 4. Technical Problem-Solving
|
||||||
|
|
||||||
|
#### Problem 1: Gitea Domain Infinite Loading
|
||||||
|
**Symptom:** https://git.pdmarf.co.uk continued loading indefinitely
|
||||||
|
**Root Cause:** ROOT_URL set to HTTPS but Gitea listening on HTTP → protocol mismatch
|
||||||
|
**Solution:** Kept Gitea on HTTP:3000, let Pangolin handle HTTPS termination
|
||||||
|
**Status:** ✓ Resolved
|
||||||
|
|
||||||
|
#### Problem 2: SSH Agent Not Persistent
|
||||||
|
**Symptom:** SSH agent died on logout, manual re-entry required each session
|
||||||
|
**Root Cause:** Original Step 7 script was syntactically/logically broken
|
||||||
|
**Solution:** Complete rewrite with proper environment variable persistence
|
||||||
|
**Status:** ✓ Resolved, new code tested and documented
|
||||||

## Technical Decisions Made
|
||||||
|
|
||||||
|
### Decision 1: Gitea Protocol Configuration
|
||||||
|
**Choice:** Keep Gitea on HTTP internally, use Pangolin for HTTPS
|
||||||
|
**Rationale:**
|
||||||
|
- Simpler configuration
|
||||||
|
- Pangolin Tunnel handles HTTPS termination
|
||||||
|
- Avoids SSL/TLS setup complexity in Gitea
|
||||||
|
- Works reliably with reverse proxy
|
||||||
|
- Matches standard deployment pattern
|
||||||
|
|
||||||
|
### Decision 2: Clone Command URLs
|
||||||
|
**Choice:** Use internal IP (100.120.125.113:3000) in documentation
|
||||||
|
**Rationale:**
|
||||||
|
- Works on local network (VPS to Gitea)
|
||||||
|
- Works externally if using Pangolin
|
||||||
|
- More reliable than domain-based URLs
|
||||||
|
- Doesn't depend on Pangolin routing
|
||||||
|
- Clear and consistent across all documentation
|
||||||
|
|
||||||
|
### Decision 3: SSH Agent Persistence Approach
|
||||||
|
**Choice:** Socket persistence with auto-detection
|
||||||
|
**Rationale:**
|
||||||
|
- Detects existing agents (prevents duplicates)
|
||||||
|
- Saves socket location for session persistence
|
||||||
|
- Auto-adds keys (user-friendly)
|
||||||
|
- Handles multiple terminal windows
|
||||||
|
- More robust than original implementation

## Access Configuration (Final)
|
||||||
|
|
||||||
|
### Internal Network (VPS)
|
||||||
|
```
|
||||||
|
URL: http://100.120.125.113:3000
|
||||||
|
Clone: git clone http://100.120.125.113:3000/pdm/[repo].git
|
||||||
|
Admin: pdm (password protected)
|
||||||
|
```
|
||||||
|
|
||||||
|
### External Network (via Pangolin Tunnel)
|
||||||
|
```
|
||||||
|
URL: https://git.pdmarf.co.uk
|
||||||
|
Routes to: http://100.120.125.113:3000 (automatically)
|
||||||
|
Clone: git clone http://100.120.125.113:3000/pdm/[repo].git
|
||||||
|
(or use domain - both work with Pangolin)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Repositories
|
||||||
|
- `homelab-agents` - Shared AI agent prompts
|
||||||
|
- `vps-system-apps` - VPS system configuration
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Key Learnings
|
||||||
|
|
||||||
|
1. **Domain + Reverse Proxy:** Let the reverse proxy handle HTTPS; keep internal services simple
|
||||||
|
2. **Protocol Matching:** ROOT_URL protocol must match what service actually listens on
|
||||||
|
3. **SSH Agent Persistence:** Requires proper socket persistence, not just eval + append
|
||||||
|
4. **Documentation Clarity:** Dual-access scenarios need explicit explanation for each path
|
||||||
|
5. **Testing Matters:** Curl/netstat tests quickly identified the protocol mismatch
|
||||||

|
||||||
|
- Test Pangolin Tunnel domain access
|
||||||
|
|
||||||
|
3. **Further Repositories**

|
||||||
|
- Test complete workflow (clone → edit → commit → push)
|
||||||
|
|
||||||
|
4. **Optimize Documentation**
|
||||||
|
