			2.c. We now have to copy this file in our container at build. Update the <code>Dockerfile</code> at line 12.

			<syntaxhighlight>
			# We install Onset files with SteamCMD and delete the base packages folder and start_linux.sh file

			rm -r /home/steam/onset/packages/ start_linux.sh

			# Copy the start_linux file as steam user and make it executable
			COPY --chown=steam:steam start_linux.sh /home/steam/onset/start_linux.sh
			RUN chmod +x start_linux.sh

			# We launch the server at start
			CMD ./start_linux.sh

Docker can be really helpful while developing your own server but it can be awesome when you are managing servers : cpu and ram limitations and reservations, crash management, auto restart, security and isolation. Let's see how we can deal with it.

== Development stack ==

For this guide we are going to create a brand new server folder.

1. Start with creation of the <code>Dockerfile</code> file and put the content below

<syntaxhighlight>
# The image we start from (a basic debian with SteamCMD)
FROM cm2network/steamcmd:root

# We'll use the "steam" user because run the server with "root" is a bad idea
USER steam

# We create our onset folder and set the base location for the image
RUN mkdir /home/steam/onset
WORKDIR /home/steam/onset

# We install Onset files with SteamCMD and delete the base packages folder
RUN /home/steam/steamcmd/steamcmd.sh +login anonymous +force_install_dir /home/steam/onset +app_update 1204170 +quit && \
rm -r /home/steam/onset/packages/

# We launch the server at start
CMD ./start_linux.sh

</syntaxhighlight>

2. Next, we need a <code>docker-compose.yml</code> file to setup our environment

<syntaxhighlight>
version: '3.7'

services:
onset:
image: steam_onset
# Tell docker where to find the Dockerfile
build:
context: .
# We need to run the container as steam user
user: "steam:steam"
# Open some ports
ports:
- "7777:7777/udp"
- "7776:7776/udp"
- "7775:7775/tcp"
</syntaxhighlight>

2.b. We can run the server now. You can use <code>docker-compose up --build</code> to try it out but we are going to have a error :
[[File:error1.png|frame]]

This is because of the new console input feature. To disable it, let's add a <code>start_linux.sh</code> to replace the base one :

<syntaxhighlight>
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
./OnsetServer --noinput
</syntaxhighlight>
