RC和RS

RC不會使用在生產環(huán)境
RS 比RC 多了標簽選擇器 ，RS 用deployment管理，用于容器編排

無狀態(tài)應用管理 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，回滾，根據(jù)標簽去控制pod，擴容，縮容

有狀態(tài)應用statefulSet

apiVersion: v1
kind: Service
metadata:name: nginxlabels:app: nginx
spec:ports:- port: 80name: webclusterIP: Noneselector:app: nginx
---
apiVersion: apps/v1
kind: StatefulSet
metadata:name: web
spec:serviceName: "nginx"replicas: 2selector:matchLabels:app: nginxtemplate:metadata:labels:app: nginxspec:containers:- name: nginximage: nginxports:- containerPort: 80name: web

daemonSet

apiVersion: apps/v1
kind: DaemonSet
metadata:labels:app: nginxname: nginx
spec:selector:matchLabels:app: nginxtemplate:metadata:labels:app: nginxspec:containers:- image: nginx:1.15.12imagePullPolicy: IfNotPresentname: nginx
