Steamcmd is probably using the old version 3 of libcurl, installing libcurl3-gnutls should fix it.

I just tried it with the new bookworm and I'm not receiving this error.

Can you go and check if this fixes the issue?

[almereyda]

Thanks, I should try it again.

Is https://github.com/CM2Walki/CS2/issues/3 still considered to be merged at some point?

[CM2Walki]

@almereyda I still have some catching up to do with my other repositories, but I'll try to get it done on the weekend.

This was a permission issue. You can see above that the .state/Steam volume has the permissions 0:0, while the image runs commands as 1000:1000. Changing the ownership of the directory prior running the container resolved the situation.

$ docker-compose run --rm login

This is due to the way how Docker handles permissions in our system. Users that are running Docker commands via an unprivileged user or run the container in rootless mode or Podman may not experience this effect.

I might also have to try this Steam Guard Mobile Authenticator app some time.

Leaving this open to discuss if the container should be built in a way that it checks for being able to write to the volume mount, before initiating the login.

steamcmd uses linux32 compiled binaries on top of linux64 base image, that's why it is unable to load libcurl library:

STEAMROOT="$(cd "$(dirname "$0")" && echo $PWD)"
...
STEAMCMD=`basename "$0" .sh`

UNAME=`uname`
if [ "$UNAME" == "Linux" ]; then
  STEAMEXE="${STEAMROOT}/linux32/${STEAMCMD}"
  PLATFORM="linux32"
  export LD_LIBRARY_PATH="$STEAMROOT/$PLATFORM:${LD_LIBRARY_PATH-}"
else # if [ "$UNAME" == "Darwin" ]; then
  ...
fi

where STEAMEXE points to /home/steam/steamcmd/linux32/steamcmd which in turn is a 32-bit Linux ELF executable

$ file /home/steam/steamcmd/linux32/steamcmd
/home/steam/steamcmd/linux32/steamcmd: ELF 32-bit LSB pie executable, Intel 80386, version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux.so.2, BuildID[sha1]=f96d428a4d4f46227bd6f6901d6998b0be787379, for GNU/Linux 2.6.24, not stripped

I guess a potential fix could look like this:

RUN dpkg --add-architecture i386 && apk update && apt install libcurl4-openssl-dev:i386
