switched from portainer to arcane recently. much easier on the eyes and the ability to save compose projects without deploying them yet is exactly what i was looking for. one thing is weird and i should prolly make an issue for it: no horizontal scroll or word wrap function in the compose editor, so for those compose files with extensive comments like npmplus you’ll have to have open in a text editor or webpage to read to the end of lines.
unexpected keyboard also does this, as well as a dedicated arrow keys button. it’s also open source and on both fdroid and play store.
oh dang, i thought i saw docs and comments saying ddns would help behind a cgnat too, must be mistaken. it’s just for isps who give semi-static ips that change, not full cgnat. after some quick googling it looks like tailscale or other vpn or cloudflare tunnel are your only options.
cgnat is doable with a dynamic dns service. you sign up free at duckdns, freedns, or desec, set up the subdomain you want (example.dedyn.io), install or host in a container a small ddns tool that will periodically (5 min typically) check what your current ip is and update your dns record with that dns service automatically with an api. some routers even have a dynamic dns setting so you can do it without a separate install.
as far as security, you’ll at a minimum want a long, unique password for any jellyfin accounts, and you should place it behind a reverse proxy like nginx, nginx proxy manager for a gui, caddy, or traeffik for some docker automagic fuckery i still don’t understand. i use nginx proxy manager, set up a wildcard *.example.dedyn.io certificate and force ssl on each service i’m forwarding.
you can get fanicer and have an authentication layer self hosted as well like authelia or authentik, but beware that apparently mobile apps and smart tv apps for jellyfin do not play nice because they use the same http port as web access and do not have the ability to pop open a web portal for a secondary auth and will not work with these yet. so it’s a good extra layer and 2fa sso addition but only if you use the webgui jellyfin and don’t rely on an app, which considering you’re asking about casting is probably not your use case.
what else you can do is set up a crowdsec or fail2ban service that will read logs from either the reverse proxy or jellyfin itself and ban ips thru your host firewall that fail to log in to help prevent bots from brute forcing in.
it’s not perfect but with a reverse proxy, ip banning tool, and strong, long passwords on jellyfin it should be relatively ok.
however it would probably be most secure to setup an openvpn or tailscale to vpn to your host and have a definitely secure link to jellyfin from everywhere. i don’t use these myself so i don’t know about limitations this way such as mobile app or smart tv app compatibility, though. and if you want to share with other users it comes with its own security considerations of letting others have a vpn into your host.
hope some of this helps, also there’s a cloudflare tunnel thing you can use instead of those dynamic dns services for domain redirect to ip behind cgnat, but i haven’t used it either and don’t know what all it entails.
good luck!
i hate the coastline ‘paradox’ and every other ‘paradox’ that’s just a missing variable. “if we measure with a big resolution it’s a smaller number of units and a small resolution is a bigger number!?” that’s not a paradox. that’s just how that variable works always. it’s not confusing or interesting at all.
ugh well that sucks butt. i’ll be trying new alternatives tonight i guess lol
any recommendations?
