I'm looking for something that can automatically handle markdown tables for me in git. If an application can do that then I can get off excel/LibreOffice calc.

Yes, but DMZ is a better solution if you want to let Router 2 handle your network

I don't do this, but I would set up oAuth like Authelia or something behind a reverse-proxy and authenticate Jellyfin clients through that.

What does renovate do again?

Sorry, I don't use either of those services. Would you be willing to explain your setup? I use my own CA with HAProxy for TLS termination (with servers side TLS) so I might be able to give some general tips. Maybe.

It definitely takes more effort to get started

You need something like stunnel/OpenVPN flag which masks your traffic as HTTPS I think. Even then DPI can probably detect it

WSUS

Hey, it's nice to talk to you. I've seen you around this community and I like your comments.

I said K8S because I work with it, but if OP doesn't need HA I guess Podman is fine too. I don't like Docker anymore after what they pulled a year or so back

Yes but if your instance holds a decent population then it's a net benefit

Run K8S on a VM on Proxmox for this stuff

Thanks for this, I didn't know Scaleway had a free service. I'll definitely take a look
