Hi,
I had a basic question about how to debug Mesos-containerizer. I had built
mesos code with debug enabled.
The detail of debugging scenario is as following:
1/ start the master with sudo GLOG_v=1
~/dist/mesos/build/bin/gdb-mesos-master.sh —ip=<IP address>
--work_dir=/var/lib/mesos
2/ start the agent with
sudo GLOG_v=1 ~/dist/mesos/build/bin/gdb-mesos-agent.sh \
—master=<master ip>:5050 \
--isolation=docker/runtime,filesystem/linux,cgroups/cpu,cgroups/mem \
--work_dir=/var/lib/mesos \
--image_providers=docker \
--executor_environment_variables="{}" \
--containerizers="docker,mesos" \
—ip=<agent IP address> \
----executor_registration_timeout=3mins
3/ run mesos-execute —master=<master IP address>:5050 —name=containertest
—docker_image=busybox --shell=false
How can I debug Mesos-containerizer for this case gracefully as it is child
process? BTW, I am running gdb with non-root use, but with sudo permission.
I also try set detach-on-fork off for gdb, but It is hung for some reason when
the child process is creating.
