k8s 安装笔记 - 部署rabbitmq单节点服务

首先配置密码• rabbitmq-secret.yaml

---
kind: Secret
apiVersion: v1
metadata:
  name: rabbitmq-secret
  namespace: devops
data:
  pass: UEA4OHcwcmQ= # P@88w0rd  base64的格式
  user: YWRtaW4= # admin  base64的格式
type: Opaque

定义StatefulSet • rabbitmq-sts.yaml

---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: rabbitmq
  namespace: devops
  labels:
    app: rabbitmq
spec:
  replicas: 1
  selector:
    matchLabels:
      app: rabbitmq
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: rabbitmq
    spec:
      volumes:
        - name: host-time
          hostPath:
            path: /etc/localtime
            type: ''
      containers:
        - name: rabbitmq
          image: 'registry.zdevops.com.cn/library/rabbitmq:3.9.22-management'
          ports:
            - name: tcp-5672
              containerPort: 5672
              protocol: TCP
            - name: http-15672
              containerPort: 15672
              protocol: TCP
          env:
            - name: RABBITMQ_DEFAULT_USER
              valueFrom:
                secretKeyRef:
                  name: rabbitmq-secret
                  key: user
            - name: RABBITMQ_DEFAULT_PASS
              valueFrom:
                secretKeyRef:
                  name: rabbitmq-secret
                  key: pass
          resources:
            limits:
              cpu: '2'
              memory: 4000Mi
            requests:
              cpu: 100m
              memory: 500Mi
          volumeMounts:
            - name: host-time
              readOnly: true
              mountPath: /etc/localtime
  serviceName: rabbitmq-headless

定义Service

apiVersion: v1
kind: Service
metadata:
  name: rabbitmq-rpc-svc
  namespace: devops
  labels:
    app: rabbitmq
spec:
  ports:
    - name: tcp-rabbitmq-5672
      protocol: TCP
      port: 5672
      targetPort: 5672
      nodePort: 31671
  selector:
    app: rabbitmq
  #clusterIP: None
  type: NodePort

---
apiVersion: v1
kind: Service
metadata:
  name: rabbitmq-svc
  namespace: devops
  labels:
    app: rabbitmq-external
spec:
  ports:
    - name: http-rabbitmq-external
      protocol: TCP
      port: 15672
      targetPort: 15672
      nodePort: 31672
  selector:
    app: rabbitmq
  type: NodePort
