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. After the install, 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  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:

root@pbspbsuser@pbs ~

Edit PBS Pro configuration files

By default configuration the mom daemon will not start in the docker container. We can change this by editing the pbs configuration file.

vi /etc/pbs.conf

Change the value of PBS_SERVER to pbs and PBS_START_MOM to 1.

vi /var/spool/pbs/mom_priv/config

and change the value of $clienthost to pbs.

$clienthost pbs

Start PBS daemons

Run PBS Pro init script to start PBS daemons.

/etc/init.d/pbs start

Create a non-root user

By default, PBS Pro does not allow submitting job as root user. You will need a non-privileged user account.

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 510
qstat

Feel free to try other PBS Pro commands and have fun.
