while trying to debug Asterisk from within a Docker container.
The image I'm using is built with this revision:
https://github.com/abourget/asterisk-
docker/tree/aefa342d7d50bafd61d07e71b50db1a580ba70f8
enabling heavier debug.
I then run:
sudo docker run --cap-add=SYS_PTRACE -ti --rm --name="asterisk13"
--net=host -v `pwd`/etc_asterisk:/etc/asterisk -v
`pwd`/voicemail:/var/spool/asterisk/voicemail -v
`pwd`/spool:/var/spool/asterisk -v `pwd`/run:/var/run/asterisk
asterisk13
with some shared directories and some dialplans.
Before getting that stacktrace, I had run:
aa-complain /etc/apparmor.d/docker
because I was trying to gdb and from inside Docker I couldn't because
of some "ptrace" permissions.
After I aa-complain'd it.. I got that stacktrace.
My host OS is Ubuntu 14.04, running Docker 1.3.1
