k8s 部署rocketmq

参考：https://www.cnblogs.com/nuomm/p/17652344.html

 

1、创建rocketmq需要的pvc，sc根据实际修改

vim rocketmq-pvc.yml

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: rocketmq-pvc
  namespace: nmg-test
spec:
  storageClassName: "nfs-client"
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

 

2、部署rocketmqnamesrv

vim rocketmq-namesrv.yml

---
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: rocketmqnamesrv
    k8s.kuboard.cn/layer: cloud
  name: rocketmqnamesrv
  namespace: nmg-test
spec:
  selector:
    matchLabels:
      app: rocketmqnamesrv
  template:
    metadata:
      labels:
        app: rocketmqnamesrv
    spec:
      nodeName: tjgjc-ai13
      containers:
        - command:
            - sh
            - /home/rocketmq/rocketmq-5.3.1/bin/mqnamesrv
          env:
            - name: TZ
              value: Asia/Shanghai
            - name: JAVA_OPT_EXT
              value: '-Duser.home=/home/rocketmq -Xms512M -Xmx512M -Xmn128m'
            - name: autoCreateTopicEnable
              value: 'true'
          image: 'apache/rocketmq:lastest'
          imagePullPolicy: IfNotPresent
          name: rocketmqnamesrv
          volumeMounts:
            - mountPath: /home/rocketmq/logs
              name: rocketmq-pvc
      volumes:
        - name: rocketmq-pvc
          persistentVolumeClaim: 
            claimName: rocketmq-pvc
---
apiVersion: v1
kind: Service
metadata:
  name: rocketmqnamesrv
  namespace: nmg-test
spec:
  ports:
    - name: namesrvport
      nodePort: 31376
      port: 9876
      protocol: TCP
      targetPort: 9876
  selector:
    app: rocketmqnamesrv
  type: NodePort

3、部署rocketmqbroker

rocketmqbroker部署到K8s上，需要修改brocket的ip，默认是docket内ip，修改为K8s的服务器Ip。采用configmap方式将broker.conf文件挂载出来。

configmap.yaml如下，需要修改brokerIP1 的值为你服务器的Ip。

vim rocketmq-config.yml

---
apiVersion: v1
data:
  config: |-
    brokerClusterName = DefaultCluster
    brokerName = broker-c
    brokerId = 0
    deleteWhen = 04
    fileReservedTime = 48
    brokerRole = ASYNC_MASTER
    flushDiskType = ASYNC_FLUSH
    brokerIP1 = 192.168.18.11
kind: ConfigMap
metadata:
  name: roketmqconfig
  namespace: nmg-test

rocketmqbroker部署的yaml文件如下:

/home/rocketmq/store是数据目录要挂载

    spec:
      containers:
        - command:
            - sh
            - /home/rocketmq/rocketmq-5.3.1/bin/mqbroker
            - '-n'
            - 'rocketmqnamesrv:9876'
            - '-c'
            - /home/rocketmq/rocketmq-5.3.1/conf/broker.conf
          env:
            - name: TZ
              value: Asia/Shanghai
            - name: JAVA_OPT_EXT
              value: '-Xms512M -Xmx512M -Xmn128m'
            - name: NAMESRV_ADDR
              value: 'rocketmqnamesrv:9876'
          image: 'apache/rocketmq:lastest'
          imagePullPolicy: IfNotPresent
          name: rocketmqbroker
          volumeMounts:
            - mountPath: /home/rocketmq/rocketmq-5.3.1/conf/broker.conf
              name: rocketmqconfig
              subPath: broker.conf
            - mountPath: /home/rocketmq/store
              name: rocketmq-pvc
      nodeName: tjgjc-ai13
      restartPolicy: Always
      volumes:
        - configMap:
            defaultMode: 420
            items:
              - key: config
                path: broker.conf
            name: roketmqconfig
          name: rocketmqconfig
        - name: rocketmq-pvc
