4.2.0.M2 Dockerfile does not work
Hi,
Up on deploying my Karaf 4.2.0.M2 custom distribution in Docker I ran into the following error on startup:
ERROR [Karaf local console user karaf] Exception caught while executing command
java.lang.NullPointerException
at org.apache.karaf.shell.impl.console.ConsoleSessionImpl.readCommand(ConsoleSessionImpl.java:438)
at org.apache.karaf.shell.impl.console.ConsoleSessionImpl.run(ConsoleSessionImpl.java:391)
at java.lang.Thread.run(Thread.java:745)
Error executing command: java.lang.NullPointerException
First I thought it was something in my configuration but when i used the Dockerfile from mkroli (https://github.com/mkroli/karaf-docker/blob/master/Dockerfile) and only changed the version to 4.2.0.M2 i got the same result.
The Docker container crashes and stops immediately.
Am I doing anything wrong?
Cheers!

Hi,
Cool.
By the way, I have a bunch of dockerfile and docker image reader, working fine
with karaf docker feature (coming soon).
I would like to publish official docker images soon. I will tackle that once
Decanter 2.0.0 is done with the PR about karaf docker.
Regards
JB

Hi,
Did you try to start in server mode: bin/karaf server ?
The reason is that bin/karaf by default tries to bind on the terminal: if you
are not in interactive mode in Docker, it will fail.

JB

Thanks for your response!
I highly doubt it is a memory issue as i have tested this on my local mac environment and on a AWS EC2 instance we run for our distribution.
Our previous Karaf 4.0.4 distribution runs without any trouble on both environments.
All help is appreciated!

I can only guess it's out of memory. Running a java docker is not as
straightforward maybe you can try fiddle with the memory parameters?
