标签选择器(labels-selector) 标签选择器使用和字段选择器类似,具体参考:https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/ 示例: 多个标签筛选(AND运算符) kubectl get pods -lenvironment=production,tier=frontend 基于集合的筛选(IN筛选): kubectl get pods -l'environment in (productio...
Replication Controller 和 Replica Set Kubernetes提供Replication Controller(简称RC)来管理Pod,RC确保任何时候K8s集群中有指定数量的Pod副本在运行。 如果少于指定数量的Pod副本,RC会启动新的Pod,反之会杀死多余的Pod,保证Pod副本数量。 Replica Set是RC升级版,确保Label Selector匹配的Pod数量维持在期望值。 #kubectl c...
