Affinity/Anti-affinity rules for Pods

Fields

additional_pod_affinity: Option<ClusterAffinityAdditionalPodAffinity>

AdditionalPodAffinity allows to specify pod affinity terms to be passed to all the cluster’s pods.

additional_pod_anti_affinity: Option<ClusterAffinityAdditionalPodAntiAffinity>

AdditionalPodAntiAffinity allows to specify pod anti-affinity terms to be added to the ones generated by the operator if EnablePodAntiAffinity is set to true (default) or to be used exclusively if set to false.

enable_pod_anti_affinity: Option<bool>

Activates anti-affinity for the pods. The operator will define pods anti-affinity unless this field is explicitly set to false

node_affinity: Option<ClusterAffinityNodeAffinity>

NodeAffinity describes node affinity scheduling rules for the pod. More info: https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#node-affinity

node_selector: Option<BTreeMap<String, String>>

NodeSelector is map of key-value pairs used to define the nodes on which the pods can run. More info: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/

pod_anti_affinity_type: Option<String>

PodAntiAffinityType allows the user to decide whether pod anti-affinity between cluster instance has to be considered a strong requirement during scheduling or not. Allowed values are: “preferred” (default if empty) or “required”. Setting it to “required”, could lead to instances remaining pending until new kubernetes nodes are added if all the existing nodes don’t match the required pod anti-affinity rule. More info: https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#inter-pod-affinity-and-anti-affinity

tolerations: Option<Vec<ClusterAffinityTolerations>>

Tolerations is a list of Tolerations that should be set for all the pods, in order to allow them to run on tainted nodes. More info: https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/

topology_key: Option<String>

TopologyKey to use for anti-affinity configuration. See k8s documentation for more info on that
