Get logs to a file

[MoryCorp]

hey, I modiifed the server.sh by just addind > log & so logs of the server would be accessible through a direct text file instead of using docker logs. But it seems that this file isn't' created at all. Have you an idea ? Thanks

[CanadaBry]

The shell script doesn’t not run from the volume you mount, so you need to use the full path such as > /home/steam/valheim/server.log &

Let me know if this fixes the issue!

[MoryCorp]

I added /home/steam/valheim/server/valheim_server.x86_64 -name "$SERVER_NAME" -port $SERVER_PORT -world "$SERVER_WORLD" -password "$SERVER_PASSWORD" -savedir "/home/steam/valheim/data" -public 1 > /home/steam/valheim/server.log & to my server.sh

This file is still not created inside the container

[InB4DevOps]

I think the problem is USER steam in the dockerfile. That user is not allowed to write to the mounted folder. See my pull request #7

Same error with provided fix.

valheim inside container belongs to user 1001 :

How did you apply the fix? You need to rebuild the container in order to make it work.

[InB4DevOps]

And did you pass the correct UID and GID values as ENV vars PGID and PUID?

[InB4DevOps]

@CanadaBry while I appreciate the time and effort you put into this container, I suggest you go and check the valheim docker at https://github.com/lloesche/valheim-server-docker

It‘s much more sophisticated and offers more functionality.

That’s very fair. This docker was created for my personal use but wanted to share it, in case anyone wanted to try it.

The reason I haven’t merged the pull is because the synology I have access to is the 416play which doesn’t have docker installed by default. I am waiting for permission to sideload the spk.

@CanadaBry don't mean to advertise here don't get me wrong please. I have learned quite a bit from your repository about docker and steamcmd so thanks!

[InB4DevOps]

Btw, how much RAM does the 416 have? Valheim server uses 2,5GB on my 416play ;-)

[CanadaBry]

Got permission to update it/sideload. It actually only has 1GB ram it looks like LOL.

I've got it running now.

This is all it took on my end to get it to play nice. Still going to look at and test your code, but will probably have to do it later.

[CanadaBry]

@CanadaBry don't mean to advertise here don't get me wrong please. I have learned quite a bit from your repository about docker and steamcmd so thanks!

I don't mind, if something works better for someone, I'drather they use it than pull their hair out. I run my docker through a dedicated box I have running Unraid, so I didn't hit most of these issues. And all my testing is done in WSL.

@MoryCorp if you still want to try my docker, just remove the USER steam from my Dockerfile, that seemed to work no issues right away on my 416. Let me know if that helps!

I really appreciate the time you're spending trying to help me, thanks.

Did you pass GID and UID to the Container? How should I do that with docker-compose ?

The reason why I am using this repo is because it's really light and it provides a docker-compose.yml. I don't need fancy options like backups etc.

At this point my server runs just fine and is able to save map if I chmod o+w the valheim directory.

Sure, I'll give it another try right now. I'll net you know in 5-10mn

[InB4DevOps]

I would not advise to remove USER steam. That means you'd run the server as root. Imagine someone somehow exploits the valheim server then your box might be screwed.

[InB4DevOps]

Btw, how much RAM does the 416 have? Valheim server uses 2,5GB on my 416play ;-)

Got permission to update it/sideload. It actually only has 1GB ram it looks like LOL.

This is all it took on my end to get it to play nice. Still going to look at and test your code, but will probably have to do it later.

This is actually not the way you should be doing it. Better create a new user with RW permissions for the two Valheim folders and only for those. That way the rest of your box is safer in case the valheim server gets compromised.

Does it work with 1GB? I mean can you play on it? :)

[MoryCorp]

Well, anyway it returns an error even if I removed steam user :

valheim    | ERROR! Failed to install app '896660' (Disk write failure)

[InB4DevOps]

Did you pass GID and UID to the Container?

[MoryCorp]

Did you pass GID and UID to the Container?

Oh yeah sorry that's what I forgot to ask. How should I do that with docker-compose ? :)

I tried something like you did with :

RUN groupadd --gid "${PGID}" -r steam 
RUN useradd -u "${PUID}" -r -g "${PGID}" -m -d /home/steam -c "Valheim server user" steam

[InB4DevOps]

on your host find UID and GID of user holory (or the one with RW permissions to the mounted folders) via id <username> then add to the compose yml file under environment (say UID is 1024, GID is 100):

below - SERVER_WORLD=Dedicated

- PGID=100
- PUID=1024

[MoryCorp]

I did a system prune -a just in case And still have disk failure

[InB4DevOps]

Can you please create a new container? Just to make sure that no existing wrong permissions are messing with you :) (or does prune do just that?)

Also try to put it below the first environment: block - not sure if it can handle 2 environments

This is what permissions eg for server_data should be. my host user is named steam in group users

[InB4DevOps]

I did a system prune -a just in case And still have disk failure

Also: the volumes part looks wrong you need to have two folders mounted as volumes, so it looks something like this:

[MoryCorp]

Can you please create a new container? Just to make sure that no existing wrong permissions are messing with you :) (or does prune do just that?)

I created a new container but yes that's the purpose of docker system prune -a, removes all unused images, containers etc.

Also try to put it below the first environment: block - not sure if it can handle 2 environments

Yeah my bad didn't even noticed there was already an environment block

Still have the same error for now

[InB4DevOps]

Check your volume mounts. The one you're using is wrong.

[MoryCorp]

I did a system prune -a just in case And still have disk failure

Also: the volumes part looks wrong you need to have two folders mounted as volumes, so it looks something like this:

Ok so i means the provider docker-compose is wrong for now ? I'll try with your volumes then

[MoryCorp]

Something like this ?

[InB4DevOps]

Wait. The directory setup has been changed since I last checked. In my version it still used two mounts. Yours is actually correct.

[MoryCorp]

Fock :D I'm killing the container then

Try an absolute path instead of ./valheim

Ok.

[InB4DevOps]

Unless you have passed 1000 as PUID this is wrong and should be 1001 (as per the screenshot you sent) 1000 is default and not the value you passed as ENV vars.

Did you clone the entire branch from my fork or just pick a few lines? I built a container based on my branch and it works. Since you have another compose yml than I have, I think that you must have done something wrong applying my changes.

please paste dockerfile, compose yml and server.sh here.

Sorry, I was actually playing the game for a bit - not only worrying about server stuff (which I also love playing with ;) ) So you had it working and then broke it again? ;-)

I think that if you pull my fork and edit the compose yml that it will then work again.
