Goal:

• setup caddy web server as user sys­temd ser­vice

Steps:

• cre­ate work­ing di­rec­tory (workdir)

  mkdir -p ~/admin/caddy
  

• down­load caddy v2 into workdir
• Allow non root to lis­ten on port 80 & 443

  sudo setcap cap_net_bind_service=+ep ./caddy
  

• cre­ate a Caddyfile in ~/admin/caddy. A sim­ple re­verse proxy ex­am­ple

  example.com {
      reverse_proxy localhost:8000
  }
  

• add this sys­temd unit file into ~/.config/systemd/user/caddy.service
