RC和RS
RC不会使用在生产环境
RS 比RC 多了标签选择器 ，RS 用deployment管理，用于容器编排
无状态应用管理 deployment
apiVersion: apps/v1
kind: Deployment
metadata:name: nginx-deploymentlabels:app: nginx
spec:replicas: 3selector:matchLabels:app: nginxtemplate:metadata:labels:app: nginxspec:containers:- name: nginximage: nginx:1.15.12ports:- containerPort: 80
deployment 涉及 更新，回滚，根据标签去控制pod，扩容，缩容
有状态应用statefulSet
apiVersion: v1
kind: Service
metadata:name: nginxlabels:app: nginx
spec:ports:- port: 80name: webclusterIP: Noneselector:app: nginx

daemonSet
