前言

使用rabbitmq-operator在k8s集群上部署rabbitmq实例。时区设置为上海

---

一、rabbitmq-operator

官网地址：https://www.rabbitmq.com/kubernetes/operator/install-operator

github上的tag列表网址：https://github.com/rabbitmq/cluster-operator/tags

二、进行部署

1.部署cluster-operator

首先获取cluster-operator.yml文件，然后增加上海时区的参数
我使用的是v2.9.0版本

wget https://github.com/rabbitmq/cluster-operator/releases/download/v2.9.0/cluster-operator.yml

增加上海时区的参数

    spec:
      containers:
      - command:
        - /manager
        env:
        - name: OPERATOR_NAMESPACE
          valueFrom:
            fieldRef:
              fieldPath: metadata.namespace
        - name: TZ
          value: Asia/Shanghai

创建operator

kubectl create -f cluster-operator.yml

2.创建自己需要的特定命名空间

准备rabbitmq-namespace.yaml文件

#https://www.rabbitmq.com/kubernetes/operator/install-operator

apiVersion: v1
kind: Namespace
metadata:
  name: slw-rabbitmq # Change this value if you want a different namespace name
  labels:
    name: slw-rabbitmq # Change this value to match metadata.name

创建命名空间

kubectl create -f rabbitmq-namespace.yaml

3.创建rabbitmq的instance

准备rabbitmq.yaml文件.
时区配置需要写在override下，卸载spec.env是不支持的。

apiVersion: rabbitmq.com/v1beta1
kind: RabbitmqCluster
metadata:
  name: rabbitmqcluster-slw
  namespace: slw-rabbitmq
  labels:
    app: rabbitmq
spec:
  image: docker.io/rabbitmq:3.13.2-management
  replicas: 3
  service:
    type: ClusterIP
    #type: NodePort
  persistence:
    storageClassName: rook-cephfs 
    storage: 5Gi
  rabbitmq:
    additionalConfig: |
      default_user = guest
      default_pass = guest
  override:
    statefulSet:
      spec:
        template:
          spec:
            containers:
              - name: rabbitmq
                env:
                - name: TZ
                  value: Asia/Shanghai

通过yaml文件创建实例

kubectl create -f rabbitmq.yaml

4.创建nodeport访问

配置文件准备rabbitmq-nodeport.yaml

kind: Service
apiVersion: v1
metadata:
  name: rabbitmqcluster-slw-nodeport
  namespace: slw-rabbitmq
  labels:
    app: rabbitmq
    app.kubernetes.io/component: rabbitmq
    app.kubernetes.io/name: rabbitmqcluster-slw
    app.kubernetes.io/part-of: rabbitmq
spec:
  ports:
    - name: amqp
      protocol: TCP
      appProtocol: amqp
      port: 5672
      targetPort: 5672
      nodePort: 30903
    - name: management
      protocol: TCP
      appProtocol: http
      port: 15672
      targetPort: 15672
      nodePort: 30904
    - name: prometheus
      protocol: TCP
      appProtocol: prometheus.io/metrics
      port: 15692
      targetPort: 15692
      nodePort: 30905
  selector:
    app.kubernetes.io/name: rabbitmqcluster-slw
  type: NodePort
  sessionAffinity: None
  externalTrafficPolicy: Cluster
  ipFamilies:
    - IPv4
  ipFamilyPolicy: SingleStack

通过yaml文件创建service

kubectl create -f rabbitmq-nodeport.yaml
