Pod placement not equally done across multiple zones
Issue
- In some cases, pods gets scheduled in the same zone even if two identical zones with identical pods are available. We are using custom labels and have adjusted
scheduler.json
to implement anti-affinity based on these labels. Thescheduler.json
was extended with the following entry to achieve service-anti-affinity.

{
"argument": {
"serviceAntiAffinity": {
"label": [ "datacenter" ]
}
},
"name": "Datacenter",
"weight": 10
}
