I was perusing selfh.st looking for something different, and stumbled across Cert Warden. It’s a centralized ACME certificate manager, which seems pretty neat. While I’ve leveraged Traefik’s ACME support in the past, I’ve had to turn to other solutions for creating certificates for services I don’t proxy through Traefik. In addition, it can make managing certs across ACME providers a bit easier, and at first glance it seems to have a much nicer API, allowing me to delegate specific credentials for consumers to pull things. I doubt this will be of much use for any web apps I’m hosting in my infrastructure, but I can see it being valuable middleware for cutting certs for appliances that don’t have ACME support built in. I might give it a shot soonish.
