About

Docker compose files for personal services. Some services are exposed to the Internet, others are served to the local network and any devices using Tailscale. Hosting provided by Cloudflare.

Prerequisites

Cloudflare

All publicly facing websites are served via Cloudflare Tunnels. To edit them, use the Cloudflare Dashboard to enter Zero Trust. Select Access > Tunnels and manage starbase-80. Select the "Public Hostname" tab to add a new subdomain.

Be sure to set the HTTP Host Header to subdomain.starbase80.dev. When adding SSL sites, set the Origin Server Name to the same value and check No TLS Verify.

Run systemctl restart cloudflared after updating any Cloudflare config. Not necessary when adding public hostnames.

SSL certificates

Publicly facing websites should get SSL certificates from Let's Encrypt on top of Cloudflare's SSL.

  1. Create a new public hostname in Cloudflare Zero Trust
  2. Set the service to be http://localhost:80
  3. In /nginx/sites, add a new .conf for the site
    • Fill out the server listen 80 block and comment out the server listen 443 block
    • Ensure the server listen 80 location / block ends with proxy_pass http://service_name_backend;
  4. Modify /nginx/compose.yml to expose the letsencrypt_one service and comment out the letsencrypt service
  5. Restart nginx: docker exec switchboard nginx -s reload
  6. In /nginx, run docker compose up -d to start the letsencrypt_one service
  7. Check in Portainer that the letsencrypt_one service exited after saving the certificate
  8. Modify /nginx/compose.yml to expose the letsencrypt service and comment out the letsencrypt_one service
  9. Modify the /nginx/sites/service_name.conf file
    • Comment out the server listen 80 block
    • Uncomment the server listen 443 block
  10. Restart nginx: docker exec switchboard nginx -s reload
  11. Go back to Cloudflare Zero Trust and change the service to be https://localhost:443
  12. Set the Origin Server Name to the same value as HTTP Host Header and check No TLS Verify

Error during git pull

If you get an error when pulling changes to nginx's sites/ folder, run this command:

sudo chown -R $USER:$USER ./nginx/sites

Restarting to pull new changes

docker exec switchboard nginx -s reload

File permissions

When adding .sh files, run chmod +x <filename> to make them executable. Or run this from the root:

sudo find . -name "*.sh" -exec chmod +x {} \;

Cron jobs

# Run this to edit the crontab
crontab -e -u jordan
