Malmo docker crashes

[okkhoy]

I built a docker image as per the docker file here.
I changed Malmo version to 0.31 and updated the links to fetch the correct version.

The build is successful; however, when I run the docker, Malmo crashes with the following stack trace.

The trace looks similar to the one in #644. Not sure if it is the same issue. (Please feel free to close the issue if it is a dup.)

// Surprise! Haha. Well, this is awkward.

@okkhoy did you ever get this working?
We've been doing some work that involved running Malmo headless within a docker container, and found that there were problems using xvfb, so we switched to using xpra - eg:

sudo apt-get install xpra
xpra start :100
export DISPLAY=:100
./launchClient.sh
etc.

I've found this to be reliable - let me know if it helps.

[okkhoy]

• I could not get the docker to start, every time I tried, I got the same stack dump as above.

• I changed xvfb to xpra in the docker file and edited the run.sh to include the following lines:

xpra start :100
export DISPLAY=:100

I leave it to the docker to start Minecraft run as earlier.

There is no crash, but it seems nothing is running. I just get the following output:

$ docker run malmo-docker
2018-03-14 15:36:13,798 rencode import error: No module named rencode

Warning: running as root

... and I get the prompt back. I don't think malmo is running!

Did I miss something?

[okkhoy]

@DaveyBiggers I noticed using xpra solves the problem on the bare-metal server. I am able to launch headless. However, docker is still a problem (as described above, I don't think Minecraft started on the docker).

[jayhardee9]

@okkhoy if you still need this to work with Docker, you just need to add python-rencode to the list of packages to install in the Dockerfile you linked, along with xpra. The "import error" you received was xpra's Python not finding the rencode module.

Also, change run.sh to:

#!/bin/sh

xpra start :100
export DISPLAY=:100
eval $*

Malmo didn't run because the last line of your Dockerfile:

ENTRYPOINT ["/root/run.sh", "/root/Malmo/Minecraft/launchClient.sh"]

is passing "/root/Malmo/Minecraft/launchClient.sh" as a parameter to run.sh. So whatever you change run.sh to will need to run its command line arg.

[okkhoy]

@jayhardee9 thanks for the pointer. I will try this next week and update/close this issue.

[okkhoy]

@DaveyBiggers this issue is resolved following @jayhardee9 's suggestion (using Malmo 0.34.0)

Wow! that took a looooong time for me to test and respond! 🙄 Sorry for the delays. 🙏

I will now close this issue.
