getlocalcert helps you manage HTTPS on private, local, and internal networks with free subdomains

This webpage provides instructions for using the acme-dns DNS challenge method with various ACME clients to obtain HTTPS certificates for private networks. Caddy, Traefik, cert-manager, acme.sh, LEGO and Certify The Web are listed as ACME clients that support acme-dns. For each client, configuration examples are provided that show how to set API credentials and other settings to use the acme-dns service at https://api.getlocalcert.net/api/v1/acme-dns-compat to obtain certificates. Interesting that so many ACME clients support the acme-dns service, providing an easy way to obtain HTTPS certificates for private networks.

    Big fan of letsencrypt’s certbot with the nginx and cloudflare (or other dns providers) plugins.

    Is there any reason to use caddy or traefik over nginx?

      Caddy takes almost all of the nginx boilerplate and handles it for you.

      If you’re doing something simple in nginx, it’s far simpler with Caddy.

      I found traefik to be a more feature rich, load balancer when used in kubernetes environments. Other than use in kubernetes, I’d say if you’re happy with nginx, keep using nginx :)

      I haven’t tried it yet but I vaguely recall traefik had a better proxy-auth setup while nginx locked it away behind their freemium plan.
