Using Docker to Instantiate PBS

Install Docker
First, make sure you have docker installed. Please see https://docs.docker.com/engine/installation/ for instructions on installing docker on your system. Please don't forget to start docker after the installation.
Launch a PBS Pro container
Open up a terminal and run:
docker run -it --name pbs -h pbs -e PBS_START_MOM=1 pbspro/pbspro bash
This tells docker to launch a PBS Pro container with an interactive shell and name it pbs. Docker will download the PBS Pro docker image from Docker Hub if the image is not already on your system.
By default PBS Pro init script does not start the mom deamon. Therefore we use the -e option to override the value for PBS_START_MOM environment variable. You can use -e to passing additional environment variables if you need to.
You should now see a terminal window that looks like:
pbsuser@pbs ~
Note that you are logged into a default non-root user account. Before we can submit and run jobs, we need to add some configurations using root account. Exit the current shell and you should return to a root shell. Run:
qmgr -c "create node pbs"qmgr -c "set node pbs queue=workq"
to create a node named pbs and add a queue to it. Then switch back to the default user account and move to its home directory:
su pbsuser
cd
Submit a job
You should now be able to submit and view jobs.
qsub -- /bin/sleep 10
qstat
Feel free to try other PBS Pro commands and have fun.
