This demo chart is to deploy two deamonsets for different sets of nodes. Pods in these two different daemonsets are assumed to consume two different configs from the configmap. Daemonsets start pods with simple nodeselectors.

Deploy

Set node labels

kubectl label --overwrite nodes node1 node_label=cpu
kubectl label --overwrite nodes node2 node_label=gpu

Deploy first chart release (configmap and cpu daemonset)

helm upgrade --install multr ./

Deploy second chart release (gpu daemonset)

helm upgrade --install multr2 ./ -f values2.yaml

Look at what we have

kubectl get configmap
kubectl get daemonset
kubectl get po
helm list

To see the config file mounted inside every pod use the following command

kubectl exec -it <pod_name> -- cat /etc/config
