Deploy instance on labeled nodes #26

Closed bromaniac closed 2 years ago

bromaniac commented 2 years ago

Hi,

I have installed the Turbonomic Operator on Openshift and I'm trying to create an instance. We only have persistent storage on some nodes designated with a label. How can I change the nodeSelector in the CR to only deploy on nodes with a certain label?

Hi @bromaniac yes you can define nodeSelector and other types of selector strategies to control where the Turbo pods are deployed. Note these are global, and apply to all pods. Examples:

  1. nodeSelector https://github.com/turbonomic/t8c-install/blob/02cd7d38240934aa15e3df99328c70627548d29f/operator/deploy/crds/charts_v1alpha1_xl_crd.yaml#L114 
    spec:
global:
  nodeSelector: kubernetes.io/os=linux
  2. tolerations (which supports an array - list of tolerations) https://github.com/turbonomic/t8c-install/blob/02cd7d38240934aa15e3df99328c70627548d29f/operator/deploy/crds/charts_v1alpha1_xl_crd.yaml#L117
  3. we also support affinity: https://github.com/turbonomic/t8c-install/blob/02cd7d38240934aa15e3df99328c70627548d29f/operator/deploy/crds/charts_v1alpha1_xl_crd.yaml#L122
  4. you can provide a storageAnnotation on the PVC that is created https://github.com/turbonomic/t8c-install/blob/02cd7d38240934aa15e3df99328c70627548d29f/operator/deploy/crds/charts_v1alpha1_xl_crd.yaml#L155

Hope this helps! eva ibm turbo product manager
