Hi Nicolas and Urban,

Thank you for your replies!

Hi Hans,

We run Slurm in k8s at the ETH Zurich to manage physical compute nodes. The link you include and Nicolas's followup already contain the basics.

We build several Docker containers based on CentOS 7 (for now) with Slurm compiled from source for the following services:

  *   slurmdbd
  *   slurmctld
  *   slurmd (used for testing as “containerized nodes”)

All these containers include an sssd daemon that interfaces with the central LDAP though we are looking at ways to streamline this part.

We use several helper containers, such as mariadb, a prometheus exporter, a file server for the code and configuration (used to transfer these to the physical nodes), and a controller that configures users, accounts, QOS, … into Slurm.

PVCs hosted on an NFS appliance provide data persistence.

A Helm chart is used to for deploying to a local test k8s instance, a test/staging cluster, and the production cluster. The chart and containers are site specific but I am happy to share the relevant code & config with you if you contact me by PM.

With kind regards,

Good Morning,

I'm working on a project at work to run SLURM cluster management components
(slurmctld and slurmdbd) as K8s pods, which manage a cluster of physical compute
nodes. I've come upon a few discussions of doing this (or more generally running
SLURM in containers); I especially found this one
(see https://groups.google.com/g/slurm-users/c/uevFWPHHr2U/m/fkwusc0JDwAJ)
very helpful.

Are there any further details or advice anyone has on such a setup?

Thank you and kind regards,
