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,
