Run folding@home on Kubernetes.

The folding project recently added support for the Corona virus (2019-nCoV).

https://foldingathome.org/2020/02/27/foldinghome-takes-up-the-fight-against-covid-19-2019-ncov/

This is a quick deployment that lets you run this on Kubernetes, should you have any spare cluster-power you'd like to donate.

Note: COVID-19 work units are being prioritized, however the folding@home client is liable to select jobs for other diseases too.

If/when they add an option to work only on COVID-19, I will update the deployment here to do so (until the pandemic is over).

kubectl apply -f https://raw.githubusercontent.com/richstokes/k8s-fah/master/folding-cpu.yaml

kubectl apply -f https://raw.githubusercontent.com/richstokes/k8s-fah/master/folding-gpu.yaml

kubectl apply -f https://raw.githubusercontent.com/richstokes/k8s-fah/master/folding-gpu-cpu.yaml

• GeForce GTX 1080
• GeForce RTX 2080
• Tesla K40m
• Tesla K80

The default install deploys 2 replicas, limited to using 1 CPU core each.

You can also run this as a DaemonSet (runs one replica per node) with:

kubectl apply -f https://raw.githubusercontent.com/richstokes/k8s-fah/master/folding-daemonset.yaml

There is a tolerations section in this .yaml you can uncomment in order to also run FAHClient on master nodes if you wish.

I've added the framework for a PriorityClass, so that K8s will preemptively evict these pods if a higher-priority one comes along.

And of course set the replica count and resource limit as appropriate depending on how much CPU you wish to donate. In my testing, memory load has been very low (<256Mi)

The most compatible way to edit the config.xml is by modifying it's values and creating your own Docker image.

You can override/mount as a configMap in Kubernetes (you can see the scaffolding for this inside folding.yaml), however FAHClient seems to what to copy/move this file around, which doesn't work if the file is mounted. You'll get a bunch of errors from the FAHClient if you do this - there may be a better way to manage the config file - PRs welcome!
