1.初始化mysql，可以创建一个cm

apiVersion: v1
data:
mysql.db.host: 10.xxx
mysql.db.name: xxxx
mysql.password: xxx
mysql.port: ‘1234’
mysql.user: xxxx
kind: ConfigMap
metadata:
name: nacos-cm
namespace: openxx
resourceVersion: ‘2047504’

2.创建StatefulSet，开放容器端口。
其中端口 7848、8848、9848、9849是必须要开放的端口，8848是web页面端口，7848是集群数据同步接口，9848、9849是nacos 2.0.0以上的版本必须开发的端口。
ports:
- containerPort: 8848
name: client-port
protocol: TCP
- containerPort: 9848
name: client-rpc
protocol: TCP
- containerPort: 9849
name: raft-rpc
protocol: TCP
- containerPort: 7848
name: asyn-raft
protocol: TCP
3.初始化容器initContainers用于加载轮询插件
peer-finder会轮询(1秒)指定的k8s service ，如果service下面的pod地址列表发生变化，则重新写入Cluster.conf文件，目的是适应k8s集群的动态扩缩容。
initContainers:
- image: >-
xxxx/xxxx/nacos-peer-finder-plugin:1.1
imagePullPolicy: Always
name: peer-finder-plugin-install
resources: {}
terminationMessagePath: /dev/termination-log
terminationMessagePolicy: File
volumeMounts:
- mountPath: /home/nacos/plugins/peer-finder
name: data
subPath: peer-finder
以下是完整的yml文件

4.接下来是svc配置

apiVersion: v1
kind: Service
metadata:
annotations:
service.alpha.kubernetes.io/tolerate-unready-endpoints: ‘true’
labels:
app: nacos
name: nacos
namespace: openapi-dev
resourceVersion: ‘2121515’
spec:
clusterIP: 192.168.238.20
clusterIPs:
- 192.168.238.20
externalTrafficPolicy: Cluster
ports:
- name: nacos-http
nodePort: 31668
port: 8848
protocol: TCP
targetPort: 8848
- name: raft-rpc
nodePort: 30441
port: 9849
protocol: TCP
targetPort: 9849
- name: ztptmw
nodePort: 31094
port: 9848
protocol: TCP
targetPort: 9848
- name: nkbm76
nodePort: 32692
port: 7848
protocol: TCP
targetPort: 7848
selector:
app: nacos
sessionAffinity: None
type: NodePort
status:
loadBalancer: {}

5.以下是headless配置，和ingress结合

apiVersion: v1
kind: Service
metadata:
annotations:
service.alpha.kubernetes.io/tolerate-unready-endpoints: ‘true’
labels:
app: nacos
name: nacos-headless

spec:
clusterIP: None
clusterIPs:
- None
ports:
- name: server
port: 8848
protocol: TCP
targetPort: 8848
- name: client-rpc
port: 9848
protocol: TCP
targetPort: 9848
- name: raft-rpc
port: 9849
protocol: TCP
targetPort: 9849
- name: old-raft-rpc
port: 7848
protocol: TCP
targetPort: 7848
selector:
app: nacos
sessionAffinity: None
type: ClusterIP
status:
loadBalancer: {}
6.ingress配置

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
labels:
k8s.kuboard.cn/name: nacos
name: nacos
namespace: sss
resourceVersion: ‘2104882’
spec:
rules:
- host: www.fff.com
http:
paths:
- backend:
service:
name: nacos-headless
port:
number: 8848
path: /
pathType: Prefix
status:
loadBalancer:
ingress:
- ip: 192.168.168.231
