Ignite running in Docker (is: General Java-Docker issue) -

-

i trying run ignite in docker container (mac os x, docker 1.9.1) committed in git:

# start java image. java:7  # ignite version env ignite_version 1.5.0-b1  workdir /opt/ignite  add http://www.us.apache.org/dist/ignite/1.5.0-b1/apache-ignite-fabric-1.5.0-b1-bin.zip /opt/ignite/ignite.zip  # ignite home env ignite_home /opt/ignite/apache-ignite-fabric-1.5.0-b1-bin  run unzip ignite.zip  run rm ignite.zip  # copy sh files , set permission add ./run.sh $ignite_home/  run chmod +x $ignite_home/run.sh  cmd $ignite_home/run.sh

after building locally apache/ignite , running image following command, container 'hangs'

docker run --expose=4700-4800 -it -p 47500-47600:47500-47600 -p 47100-47200:47100-47200 --net=host -e "config_uri=https://raw.githubusercontent.com/apache/ignite/master/examples/config/example-default.xml" apacheignite/ignite-docker

when connecting container (docker exec -ti apache/ignite /bin/bash) , running command in verbose mode via bash, hangs on org.apache.ignite.startup.cmdline.commandlinerandomnumbergenerator:

bash -x /opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/bin/ignite.sh https://raw.githubusercontent.com/apache/ignite/master/examples/config/example-default.xml

output hangs:

+ cp='/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/*:/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/*:/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/*:/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/licenses/*' ++ /usr/bin/java -cp '/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/*:/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/*:/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/*:/opt/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/licenses/*' org.apache.ignite.startup.cmdline.commandlinerandomnumbergenerator

looking @ code of commandlinerandomnumbergenerator, don't see special, 1 line generate uuid. there other things automatically started somehow causes locking threat application cannot exit?

this seems docker issue java in general, see also: https://github.com/docker/docker/issues/18180

several solutions possible:

i think practice (for now) add system.exit main methods in ignite since independent of alternative hacks on docker or linux in general (linux kernel need aufs upgrade , many machine may lag behind before that). way future ignite version can safely installed on older kernels also.
