From 6220f6c4da5b1eb19e40ee0d840d6373ddcadcd4 Mon Sep 17 00:00:00 2001 From: Randy Fay Date: Sun, 8 Feb 2026 21:42:23 -0700 Subject: [PATCH 1/3] Fix documentation: remove hallucinations and correct all inaccuracies MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major corrections across all documentation files: - Fix Git SSH flow: document actual `coder publickey` command instead of hallucinated "Account → SSH Keys" UI - Fix port forwarding: reference actual "Ports section" in Coder UI - Fix URL format: use correct `https://PORT--workspace--owner.domain/` pattern - Remove hallucinated commands: `coder users update`, `coder templates update` - Remove all Enterprise-only features (not using Enterprise) - Change all DDEV docs URLs from ddev.readthedocs.io to docs.ddev.com - Remove hardcoded DDEV v1.24.10 references (use "latest" concept) Simplifications to operations-guide.md: - Remove manual Docker build instructions (Makefile only) - Remove image customization details (reference image/README.md) - Remove version strategy section (not useful) - Simplify workspace update documentation Remove from comparison-to-local.md: - Feature parity matrix (not useful per user feedback) All documentation now accurately reflects what actually exists and works.

Sysbox Runtime + +Sysbox provides **secure nested containers** without privileged mode: +- No `--privileged` flag required +- Isolated Docker daemon per workspace +- AppArmor and seccomp profiles configured + +**Security profiles in template.tf:** +```hcl +security_opt = ["apparmor:unconfined", "seccomp:unconfined"] +``` + +These are required for Sysbox functionality and are safer than `--privileged`. + +### User Isolation + +- Each workspace has isolated Docker daemon +- Workspaces cannot access other workspaces' Docker containers +- Users have sudo access **inside their workspace only** + +### Registry Security + +- Store registry credentials in Coder secrets or environment variables +- Avoid hardcoding credentials in template.tf +- Use private registries for proprietary images + +### Network Security + +- DDEV uses Coder's port forwarding (not direct host binding) +- Ports are proxied through Coder server +- Configure firewall rules on Coder server, not individual workspaces + +## Best Practices + +### Resource Allocation + +- **Default**: 4 CPU cores, 8GB RAM (suitable for most PHP/Node projects) +- **Large projects**: 8 cores, 16GB RAM +- **Small projects**: 2 cores, 4GB RAM + +Monitor resource usage and adjust template defaults accordingly. + +### Template Naming + +- Use clear, descriptive names: `ddev-user`, `ddev-developer` +- Version templates for major changes: `ddev-user-v2` +- Avoid generic names: `template1`, `test` + +### Image Management + +- Always tag images with specific versions **and** `latest` +- Test images before pushing to production registry +- Document changes in git commit messages +- Keep Dockerfile layer count reasonable (current: ~10 layers) + +### Workspace Lifecycle + +- **Short-lived workspaces**: Ideal for temporary work, prototyping +- **Long-lived workspaces**: Personal development environments +- Stop workspaces when not in use to save resources + +### Documentation + +- Keep `CLAUDE.md` updated for

process +ps aux | grep dockerd + +# Check Docker socket +ls -la /var/run/docker.sock + +# Check dockerd logs +cat /tmp/dockerd.log + +# Check systemd service +systemctl status docker +``` + +**Common causes:** + +**Cause 1: Sysbox not installed on host** +```bash +# On Coder host +sysbox-runc --version + +# Install if missing +apt-get update +apt-get install sysbox-ce +systemctl restart docker +``` + +**Cause 2: Container not using Sysbox runtime** +```bash +# Check template.tf +grep runtime ddev-user/template.tf +# Should be: runtime = "sysbox-runc" +``` + +**Cause 3: Missing security profiles** +```bash +# Check template.tf +grep security_opt ddev-user/template.tf +# Should include: +# security_opt = ["apparmor:unconfined", "seccomp:unconfined"] +``` + +**Cause 4: Docker volume not mounted** +```bash +# Check volume mount +docker inspect coder- | grep "Destination.*docker" +# Should show: /var/lib/docker mounted + +# Check volume exists +docker volume ls | grep dind-cache +``` + +**Solution:** +```bash +# Fix template.tf and redeploy +coder templates push --directory ddev-user ddev-user --yes + +# Recreate workspace +coder delete my-workspace --yes +coder create --template ddev-user my-workspace --yes +``` + +### Docker Daemon Crashes + +**Symptom:** Docker works initially but stops responding + +**Check:** +```bash +# Inside workspace +journalctl -u docker -f + +# Check disk space +df -h /var/lib/docker + +# Check for OOM kills +dmesg | grep oom + +# Check Docker daemon logs +cat /tmp/dockerd.log +``` + +**Solution:** +```bash +# Increase workspace memory +coder update my-workspace --parameter memory=16 + +# Clean up Docker resources +docker system prune -a --volumes -f + +# Restart Docker daemon +sudo systemctl restart docker +``` + +### Docker Permission Errors + +**Symptom:** `permission denied while trying to connect to Docker daemon` + +**Check:** +```bash +# Inside workspace +groups # Should include "docker" +ls -la /var/run/docker.sock +getent group docker # Check GID +``` + +**Solution:** +```bash +# Check docker_gid in template.tf matches host +# Default is 988 + +# Add user to docker group (should be done in startup script) +sudo usermod -aG docker $USER + +# Or check group_add in template.tf: +# group_add = ["988"] +``` + +## DDEV Container Issues + +### DDEV Containers Won't Start + +**Symptom:** `ddev start` fails or containers exit immediately + +**Check:** +```bash +# Inside workspace +ddev start --debug + +# Check Docker daemon +docker ps +docker info + +# Check DDEV version +ddev version + +# Check for port conflicts +docker ps -a | grep ddev +``` + +**Common causes:** + +**Cause 1: Docker daemon not running** +```bash +docker ps +# If fails: systemctl status docker +``` + +**Cause 2: Insufficient resources** +```bash +docker stats +free -h +# Increase workspace memory/CPU if needed +``` + +**Cause 3: Port conflicts** +```bash +ddev describe +# Check for conflicting projects +ddev list +ddev stop --all +``` + +**Cause 4: Corrupt DDEV project** +```bash +ddev delete --omit-snapshot +rm -rf .ddev +ddev config --auto +ddev start +``` + +**Solution:** +```bash +# Clean restart +ddev poweroff +ddev start + +# Or rebuild +ddev delete --omit-snapshot +ddev config --auto +ddev start +``` + +### DDEV Database Import Fails + +**Symptom:** `ddev import-db` fails with memory or timeout errors + +**Check:** +```bash +# Check workspace resources +docker stats + +# Check database container logs +ddev logs db + +# Check disk space +df -h +``` + +**Solution:** +```bash +# Increase memory +coder update my-workspace --parameter memory=16 + +# Split large imports +gunzip < dump.sql.gz | split -l 50000 - split_ +for file in split_*; do ddev import-db --file=$file; done + +# Or use mysql directly +ddev mysql < dump.sql +``` + +### DDEV URLs Not Accessible + +**Symptom:** DDEV project URLs don't work + +**Check:** +```bash +# Check DDEV status +ddev describe + +# Check port forwarding in Coder UI +# Should see ports 80, 443, 8080, 8443, 8025, 8026 + +# Test locally in workspace +curl localhost:80 +``` + +**Solution:** +- Access via Coder port forwarding UI (not direct URLs) +- Click on port links in Coder dashboard under "Apps" +- DDEV URLs shown by `ddev describe` won't work directly +- Use Coder's proxied URLs instead + +## Permission and File Ownership + +### File Ownership Issues + +**Symptom:** Files owned by root or wrong UID + +**Check:** +```bash +# Inside workspace +ls -la /home/coder +id # Should be UID 1000 + +# Check volume ownership on host +ls -la /home/coder/workspaces/- +``` + +**Solution:** +```bash +# Startup script should fix this automatically +# If not, run manually: +sudo chown -R coder:coder /home/coder + +# Or on host: +chown -R 1000:1000 /home/coder/workspaces/- +``` + +### Sudo Doesn't Work + +**Symptom:** `sudo: command not found` or permission denied + +**Check:** +```bash +# Inside workspace +which sudo +cat /etc/sudoers.d/coder +groups +``` + +**Solution:** +Rebuild image with sudo configured: +```dockerfile +# In image/Dockerfile +RUN echo "coder ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/coder +``` + +### Can't Write to Home Directory + +**Symptom:** Permission denied writing to `/home/coder` + +**Check:** +```bash +ls -la /home/coder +df /home/coder # Check if volume mounted +``` + +**Solution:** +```bash +# Fix ownership +sudo chown -R coder:coder /home/coder + +# Check volume mount in template.tf +# Should have: +# volume { +# container_path = "/home/coder" +# host_path = "/home/coder/workspaces/${...}" +# } +``` + +## Networking and Port Forwarding + +### Can't Access DDEV Project + +**Symptom:** Coder port forwarding shows ports but URLs don't work + +**Check:** +```bash +# Inside workspace +ddev describe +curl localhost:80 +docker ps | grep ddev + +# Check Coder port forwarding UI +# Should see forwarded ports +``` + +**Solution:** +- Use Coder's port forwarding links (not DDEV's URLs) +- Ensure DDEV is configured for Coder environment +- Check `host_webserver_port` in `.ddev/global_config.yaml` + +### Port Conflicts + +**Symptom:** Port already in use errors + +**Check:** +```bash +# Inside workspace +ddev list +docker ps + +# Check for conflicting projects +netstat -tlnp | grep :80 +``` + +**Solution:** +```bash +# Stop all DDEV projects +ddev stop --all + +# Or configure different ports in .ddev/config.yaml: +router_http_port: "8080" +router_https_port: "8443" +``` + +### VS Code Port Forwarding Not Working + +**Symptom:** VS Code can't forward ports from workspace + +**Check:** +```bash +# Verify service is listening +netstat -tlnp | grep + +# Test locally +curl localhost: +``` + +**Solution:** +- Use Coder's port forwarding (not VS Code's) +- Configure ports in `template.tf` `coder_app` resources +- VS Code port forwarding may not work with Docker-in-Docker + +## VS Code for Web Issues + +### VS Code Won't Load + +**Symptom:** VS Code app shows blank page or infinite loading + +**Check:** +```bash +# Check workspace is running +coder list + +# Check agent is running +coder ssh my-workspace -- echo "Agent OK" + +# Check browser console for errors +``` + +**Solution:** +- Refresh browser +- Clear browser cache and cookies +- Try different browser +- Restart workspace: `coder restart my-workspace` + +### VS Code Extensions Won't Install + +**Symptom:** Extensions fail to install or don't work + +**Check:** +```bash +# Check disk space +coder ssh my-workspace -- df -h + +# Check VS Code version +# (View in VS Code: Help → About) +``` + +**Solution:** +- Some extensions require desktop VS Code +- Use SSH connection with desktop VS Code: + ```bash + coder config-ssh + # Then connect via VS Code Remote-SSH + ``` + +### VS Code Terminal Issues + +**Symptom:** Terminal in VS Code doesn't work or has wrong shell + +**Check:** +```bash +# Inside workspace terminal +echo $SHELL +which bash zsh + +# Check VS Code terminal settings +``` + +**Solution:** +- Default shell is bash +- Change in VS Code settings: `Terminal › Integrated › Default Profile: Linux` +- Restart VS Code + +## Performance Problems + +### Workspace is Slow + +**Check:** +```bash +# Check resource usage +docker stats coder- + +# Inside workspace +top +df -h +docker stats +``` + +**Causes:** +1. **Insufficient resources** - Increase CPU/memory +2. **Disk I/O** - Check Docker volume performance +3. **Too many DDEV projects running** - Stop unused projects + +**Solution:** +```bash +# Increase resources +coder update my-workspace \ + --parameter cpu=8 \ + --parameter memory=16 + +# Stop unused DDEV projects +ddev stop --all +ddev start # Only current project + +# Clean Docker cache +docker system prune -a -f +``` + +### Docker Build is Slow + +**Symptom:** `docker build` or DDEV builds take very long + +**Check:** +```bash +# Check Docker info +docker info | grep "Storage Driver" + +# Check disk performance +dd if=/dev/zero of=/tmp/test bs=1M count=1024 +rm /tmp/test +``` + +**Solution:** +- Increase workspace resources +- Use Docker BuildKit: `DOCKER_BUILDKIT=1 docker build ...` +- Use multi-stage builds to reduce layer count +- Host may need SSD for `/var/lib/docker` volumes + +### DDEV Performance Issues + +**Symptom:** DDEV project is slow (page loads, composer, npm) + +**Check:** +```bash +ddev describe +docker stats $(docker ps -q --filter name=ddev) +``` + +**Solution:** +```bash +# Increase workspace resources +coder update my-workspace --parameter memory=16 + +# Use NFS for file sharing (if Mutagen is slow) +# Edit .ddev/config.yaml: +# nfs_mount_enabled: true + +# Disable xdebug when not needed +ddev xdebug off +``` + +## Debugging Tools + +### Viewing Logs + +**Workspace agent logs:** +```bash +#

Remove local-specific settings like `router_http_port`. Most settings work identically. + +**Q: Do all DDEV project types work?** + +A: Yes, all 20+ project types work (WordPress, Drupal, Laravel, etc.). DDEV is identical; only access method changes. + +**Q: Can I use Xdebug?** + +A: Yes, `ddev xdebug on` works. Configure your IDE for remote debugging via SSH. + +**Q: What about PHPStorm?** + +A: Use PHPStorm with SFTP deployment mode and remote interpreter. Not as seamless as local but works. + +**Q: Is it slower?** + +A: File operations are slower (network latency). Database queries and page loads are similar. Tradeoff for remote access and team consistency. + +**Q: Can I work offline?** + +A: No, internet required. Local DDEV better for offline work. + +**Q: What if workspace is deleted?** + +A: All data lost (like deleting local project). Always commit and push to Git. Admins can backup volumes. + +**Q: How much does it cost?** + +A: Depends on cloud provider and usage. ~$30-110/month per workspace. Stop when not in use to save costs. + +**Q: Can I migrate back to local DDEV?** + +A: Yes, easily. Clone Git repo, use same .ddev/config.yaml, run `ddev start`. + +## Conclusion + +**Coder DDEV is not a replacement for local DDEV in all cases.** It's a different deployment model with different tradeoffs. + +**Best for:** +- Teams prioritizing consistency and onboarding speed +- Remote/distributed teams +- Organizations with centralized IT management +- Projects needing more resources than laptops provide + +**Local DDEV still best for:** +- Solo developers with good local setup +- Performance-critical workflows +- Offline work requirements +- Budget-constrained personal projects + +**Key insight:** Most teams value consistency, onboarding speed, and remote access over filesystem performance.

DDEV listens on ports 80/443 inside workspace +2. Coder forwards these ports through its proxy +3. You access via Coder's forwarded URLs + +### Access Your Project + +**Via Coder Web UI (Recommended):** +1. Go to Coder dashboard +2. Find your workspace +3. Look for the **Ports** section +4. Click on the URL for port **80** (HTTP) or **443** (HTTPS) +5. Your DDEV project loads in a new tab + +The forwarded URLs look like: `https://8080--workspace-name--owner.coder.example.com/` + +**Via CLI Port Forward:** +```bash +# Forward port to your local machine +coder port-forward my-first-workspace --tcp 8080:80 + +# Then access in your browser: +# http://localhost:8080 +``` + +**Check DDEV status:** +```bash +ddev describe +# Shows project details and status +# Note: URLs shown by ddev describe won't work - use Coder's forwarded URLs instead +``` + +## Step 7: Make Changes and Test + +### Edit Files + +**Via VS Code for Web:** +1. Open VS Code (Apps → VS Code in Coder UI) +2. Navigate to `~/projects/my-site` +3. Edit files normally +4. Changes are saved automatically + +**Via SSH and vim:** +```bash +coder ssh my-first-workspace +cd ~/projects/my-site +vim web/index.php +``` + +### Reload and Test + +```bash +# Refresh your browser to see changes +# Or use DDEV commands: + +ddev describe # Show project info +ddev logs # View container logs +ddev exec # Run command in web container +``` + +### Common DDEV Commands + +```bash +# Start project +ddev start + +# Stop project +ddev stop + +# Restart project +ddev restart + +# View status +ddev describe + +# View logs +ddev logs + +# SSH into web container +ddev ssh + +# Run Composer +ddev composer install + +# Run npm +ddev npm install +ddev npm run dev + +# Import database +ddev import-db --file=dump.sql.gz + +# Export database +ddev export-db --file=dump.sql.gz + +# View all commands +ddev help +``` + +## Step 8: Working with Git + +### Configure Git + +```bash +# Inside workspace +git config --global user.name "Your Name" +git config --global user.email "your.email@example.com" +``` + +### Set Up Git SSH for Private Repositories + +To clone private repositories or push to GitHub/GitLab/etc, you need to add your Coder public key to your Git host. + +**Step 1: Get your Coder public key** +```bash +# Inside workspace (via SSH or VS Code terminal) +coder publickey + +# This shows your Coder-managed public key +# Copy the entire output (starts with ssh-ed25519 or ssh-rsa) +``` + +**Step 2: Add key to your Git host** + +**For GitHub:** +1. Go to https://github.com/settings/keys +2. Click **New SSH key** +3. Paste your Coder public key +4. Click **Add SSH key** + +**For GitLab:** +1. Go to https://gitlab.com/-/profile/keys +2. Paste your Coder public key +3. Click **Add key** + +**For Bitbucket:** +1. Go to https://bitbucket.org/account/settings/ssh-keys/ +2. Click **Add key** +3.
