比如创建了一个Deployment监控student Pod,配置文件里面设置副本为3个,但是实际启动了两个,那么Deployment就会向etcd(其实是向apiserver发送指令,但是apiserver也是向etcd进行操控)写入一条资源,调度器监控到student 这个资源进行了改变(添加) 那么调度器会通过调度策略寻找合适的node运行pod。 所以在开发控制器的时候,设计in...
Kubernetes是一个颇受欢迎的容器编排平台,它使得开发人员和管理人员可以更加灵活和高效地管理容器化的应用程序。然而,在使用Kubernetes时有一些秘密和注意事项需要注意。 1. 密钥和秘密 在容器中保存机密信息非常重要,例如密码,数据库凭据等。Kubernetes中的'秘密(Secrets)'是用于安全保存敏感数据的特殊对象。这些密钥和凭...

node亲和性 node1 16核64G内存,node2 16核64G内存,node3 32核 64G内存,让pod向性能比较好的node上运行即pod亲和node3, pod亲和于什么样的node去运行,在调度的时候affinity是必须的,但在实际运行的时候又用不到,只是调度的时候用到。 在调度的时候80%的概率到一个node,20%的概率到另外一个node。
