Troubleshooting

I run docker-compose up -d in my pc,(ubuntu 14.04 docker 1.9.1) and I run into the following error:

  ERROR: Cannot start container 84d255960b938a53d168f9fe5ebc3940568d508f3a85cc6a4190f326d5252725: /dev/mqueue is not mounted, but must be for --ipc=host

first I run ls -al /dev | grep mqueue to see if the dir exists:

geek@prod:ganglia$ ls -al /dev | grep mqueue
geek@prod:ganglia$

This indicates /dev/mqueue does not exist. So I take the following action:

geek@prod:ganglia$ sudo mkdir -p /dev/mqueue

and run docker-compose up -d,the container runs correctly
