# PodDisruptionBudget：保证节点维护、AKS 节点池升级这类**自愿中断**时至少留一个副本在跑。
|
|||
|
|
# 没有它，一次节点池升级可能把两个副本同时驱逐，造成一次没人预料到的短暂全站不可用。
|
|||
|
|
#
|
|||
|
|
# 注意 PDB 只管自愿中断（drain/evict），管不了节点宕机、OOMKilled 这类非自愿中断——
|
|||
|
|
# 那是 replicas + 探针的事。
|
|||
|
|
#
|
|||
|
|
# Dev 没有 PDB：单节点 k3s 上 replicas=1，minAvailable: 1 会让节点永远 drain 不掉。
