are you sharing a server solely to play with friends?

You could consider using something like zerotier to create a private network

I havent used kodi in a long time, since swapping to jellyfin. I personally found kodi would always buffer sometimes, far more than it should ever need to. With jellyfin, same server, no buffer

Happy to be corrected but I think code server doesn’t use the exact vscode build from microsoft

https://coder.com/docs/code-server/FAQ#why-cant-code-server-use-microsofts-extension-marketplace

And I think the trackers you are (rightly) concerned about aren’t in code server but they have their own equivalent. You can disable the telemetry though

Personally, literally some postit notes for my own selfhosted projects

Ive not shared mine to the point anyone can arbitrarily get media. They have to ask. And I can always say “Oh its not available on my sources” or whatever

Unfortunately not in this example. It has the compose to spin up masto, and the variables to set to tell it where redis etc is

You will need to review all the required variables and configure as you require. But basically, yeah

EDIT - NO

its not just grab and run. From the docs,

This container requires separate postgres and redis instances to run.

If youre looking for a sample docker-compose,

Some things, or points, to consider.

1. Do you want whatever you’re hosting to be internet accessible? Or local network only? As it being able to access from anywhere
2. If its something you want to be able to use full time, youll eventually want a dedicated machine. I have an *arr stack etc, which I share with a private group. Eventually downtime was an actual consideration and interrupted my normal usage of my main machine. I picked up a secondhand elitedesk mini Pc for £150 and its doing really well.
3. Potentially make use of tools like Zerotier for private networking (others hopefully will chime in with alternatives, but I have had good success with zerotier.
4. How do you want to host it, and are you willing to learn? Get a bit of knowledge on docker or podman but this is hardmode as most examples will be docker specific. Using containers will make things simpler. The most complicated part IMO is networking but even then its more docker networking stuff than general TCP/IP - (like you mentioned in your post)
5. OS - you mentioned using Linux? I personally use Ubuntu just out of defaulting to what i’ve previously used. But Im currently using Manjaro on my non host PC, which I am liking
6. Keep things secure - the more you expose to the internet, the more risk. Keep exposure as small as possible, use letsencrypt or alternatives for anything you want to access over the internet etc

good luck have fun!

NPM as in nginx and not Node Package Manager?

When you said Jellyfin streaming isn’t working - are you able to actually get to Jellyfin UI and its the stream failing, or you can’t access Jellyfin at all via nginx?

It depends whether a whole season torrent exists or not. If sonarr can identify one thats a whole season, it should download that when you search at season level. If youve searched individual episode at a time, youll get a single one.

You can do an interactive search and iirc specify full season during that search

Check on activity page to see if its stuck on found/downloading/extracting/importing

Check trackers/sources aren’t down

Check in log.txt for exceptions

When you tried caddy and received an error, that looks like you are getting the wrong image name.

Then you mentioned deleting caddyfile as the configuration didn’t work. But, if I am following correctly the caddyfile wouldn’t yet be relevant if the caddy container hadn’t actually ran.

Pulling from Caddys docs, you should just need to run

$ docker run -d -p 80:80 \
    -v $PWD/Caddyfile:/etc/caddy/Caddyfile \
    -v caddy_data:/data \
    caddy

Where $PWD is the current directory the terminal is currently in.

Further docs for then configuring for HTTPs you can find here under

Automatic TLS with the Caddy image

Like other commenter said, regardless of podman or docker you will need to handle port forwarding, and any firewall changes.

Port forwarding through docker or podman is pretty similar, if not identical.

I have heard good things about podman but I personally had some strange issues when moving from docker to podman, specifically transferring docker networks to the podman equivalent.

When I am home Ill get an example from my setup 👍

On my phone so I haven’t got the access to give you a good example.

You see in your compose file in your original post you have ‘8080:8080’ under ports?

You should be able to add another line, the left hand side of the colon exposing a different port like so

…
ports: 
    - ‘8080:8080’
    - ‘9090:9090’ 
…

then one service you can access on port 8080 and the other you access on 9090

then under each service you want to expose you add the other port mappings

qtorrent:
    ports: 
        - 8080:8080

sabnzb:
    ports: 
        - 9090:8080

edit - so you should end up with the vpn container exposing 8080 which points to the service exposing 8080 which maps to application listening on 8080

and the same for 9090 -> 9090 -> 8080

In the VPN service you just expose the port you want and map it to the listener port on the service

vpn: ports: - 5000:8080 - 6000:8080

where you have

servicea listening on 8080 and serviceB on 8080 but exposed on 5000 and 6000 in the VPN service

for example

You can also map different ports to the container. For sake of argument lets say qtorrent had a fixed port you cannot change, that’s just what the application listens to. You can then map a different container port to that application port.

tldr, OP, you can’t have two containers in docker on the same container port

How cheap are you seeing this hardware? In the UK at least I could get an 8 port managed switch for £25 (on sale, full price £35)

A PCIE 2x gigabit network card runs at £30 each, to match ports itd cost £120
