I’m going round in circles on this one.
What I want to do is:
- serve up my self-hosted apps with https (to local clients only - nothing over the open web)
- address them as ‘app.server.lan’ or ‘sever.lan/app’
- preferably host whatever is needed in docker
I think this is achievable with a reverse proxy, some kind of DNS server and self-signed certs. I’m not a complete noob but my knowledge in this area is lacking. I’ve done a fair bit of research but I’m probably not using the right terminology or whatever.
Would anyone have a link to a good guide that covers this?
Yeah, that’s exactly why I didn’t use my own CA. There’s a plethora of devices that you now need to import the CA to and then you need to hope, that every application uses the system cert store and doesn’t roll its own (IIRC e.g. Firefox uses its own cert store and doesn’t use the system cert store. Same for every java based application,…)
It’s fiddly with Caddy, as you need a specific plugin to get it to work with anything else than the default challenge. That means using a custom build via caddy - and with docker, you’re SOL. BUT you can just use certbot and point caddy to the cert file in your file system.
