Saat menghabiskan pod Istio, beberapa node mungkin tidak habis karena memiliki jumlah replika
1, sedangkan diperlukan 3 replika atau lebih.
Untuk menghindari hal ini, Anda harus menetapkan jumlah replika minimum untuk setiap properti setidaknya ke 3.
Saat mencadangkan dan menghabiskan node Istio, Anda mungkin melihat error seperti:
kubectl drain` failed to evict and reschedule pods to another node due to PodDisruptionBudget definitions:
===
NAMESPACE NAME MIN AVAILABLE MAX UNAVAILABLE ALLOWED DISRUPTIONS AGE
istio-system istio-ingressgateway 1 N/A 2 5d11h
istio-system istio-pilot 1 N/A 2 5d11h
===
Untuk istio-ingressgateway dan istio-pilot, Anda dapat menetapkan
properti istio.ingressgateway.replicaCountMin dan
istio.pilot.replicaCountMin ke 3
atau yang lebih tinggi. Lihat
