Slurm Docker

This repository defines a Docker environment for running the Slurm scheduler.

Features

• Runs a Slurm controller, a Slurm daemon, and an ssh server in a single container

• Creates a user called "user" who can log in with ssh using a password

• The password is automatically generated and echoed to standard output when the container is started

• The "compute node" represented by the Slurm daemxon is configured to have a single socket with a single core

Requirements

• Docker
• Docker Compose

Quick start

• Bring up the docker-compose stack:

  docker-compose up -d
  

  Check the logs with

  docker-compose logs
  

  and read out the user's password from the start of the log. It should appear as

  slurm_1  | Set password for 'user' to 'lav8IeGheuch'
  

  but with a different randomly-generated password on each run.
• Log in via ssh:

  ssh -p 2022 user@localhost
  

• Change to the scratch directory (which is a persistent volume):

  cd /scratch/user
  

• Submit a test job:

  sbatch /usr/share/slurm-examples/testjob.sh
  

• Check the output file:

  cat testjob_*.log
  

  The suffix in the log file name is the job ID, so will change for each new job.
• If the log file says "Hello World!", then everything is working!
