Issue type: Docker Container won’t stay running
OS Version/build: Windows 10 Enterprise / Docker 17.09.1-ce-win42 (14687) Channel: Stable
App version: Custom 7 Days to Die Dedicated server image built off of official Ubuntu 16.04 image
Hi everyone,
I am learning Docker, and I decided to build a 7 Days To Die dedicated game server image to test my learning and experiment. I took the official Ubuntu image and then installed SteamCMD on it. I then took that image and created the following Dockerfile:
FROM churromancer/steamcmd:1.0
WORKDIR /root/Steam
RUN ./steamcmd.sh +login anonymous +force_install_dir ./7days +app_update 294420 validate +quit
WORKDIR /root/Steam/7days
COPY serverconfig.xml .
EXPOSE 26900/tcp 8080-8082/tcp 26900-26902/udp
ENTRYPOINT /root/Steam/7days/7DaysToDieServer.x86_64 -configfile=serverconfig.xml -logfile /dev/stdout
The image builds correctly and when I create a container from it the server starts and I see the output I’d normally see when a 7 Days To Die dedicated server is spun up. However, after the server starts the container then exits and stops. If I restart the stopped container, the same thing happens where it starts the server and then Docker exits. If I exec into my SteamCMD image and run all of these commands in my dockerfile manually, then the server starts and remains running.
This is how I am starting the container after building the image named “7days”:
docker container run --name testserver 7days
I have also tried the following with the same results:
docker container run -it --name testserver 7days
What is wrong with my Dockerfile or the command line syntax that is preventing the server from staying running? I understand that this is most likely an app issue and not an issue with Docker itself, but I am wondering if anyone else has experienced this type of behavior and if so were they able to modify something within the dockerfile and/or container to resolve?
Thank you all for your help!
