Appendix B: Define Affinity and Tolerations

Define affinity and tolerations for agility-system

1. Define affinity and tolerations override values file

   cat <<EOF> agility-system-values-affinity-tolerations.yaml
   affinity: &affinity
     nodeAffinity:
       requiredDuringSchedulingIgnoredDuringExecution:
         nodeSelectorTerms:
         - matchExpressions:
           - key: agility-instance
             operator: In
             values:
             - dtgroup
   tolerations: &tolerations
   - key: "agility-instance"
     operator: "Equal"
     value: "dtgroup"
     effect: "NoSchedule"
   
   pgo:
     affinity: *affinity
     tolerations: *tolerations
   
   strimzi-kafka-operator:
     affinity: *affinity
     tolerations: *tolerations
   EOF

2. Deploy agility-system adding the new values file

   helm --namespace kube-system upgrade --install --create-namespace agility-system ./agility-system --values agility-system-values-affinity-tolerations.yaml

Define affinity and tolerations for agility-services
