1.准备K8S环境
2.下载基础镜像，需要安装两种插件：autocluster、rabbitmq_management
方法一：
下载已有插件镜像
[root@localhost ~]#docker pull registry.cn-hangzhou.aliyuncs.com/wise2c/kubernetes-rabbitmq-autocluster
下面是自定义的Dockerfile
FROM registry.cn-hangzhou.aliyuncs.com/wise2c/kubernetes-rabbitmq-autocluster:latest
RUN rabbitmq-plugins enable --offline rabbitmq_management构建新镜像（在当前目录新建Dockerfile）
docker build -t . rabbitmq:new
方法二：
下载原始镜像
下面是自定义的Dockerfile（需要下载autocluster-0.6.1.ez插件）
FROM rabbitmq:3.6.8 ENV RABBITMQ_USE_LONGNAME=true AUTOCLUSTER_LOG_LEVEL=debug AUTOCLUSTER_CLEANUP=true CLEANUP_INTERVAL=60 CLEANUP_WARN_ONLY=false AUTOCLUSTER_TYPE=k8s LANG=en_US.UTF-8 ADD plugins/*.ez /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.8/plugins/ RUN rabbitmq-plugins enable --offline autocluster RUN rabbitmq-plugins enable --offline rabbitmq_management
构建新镜像（在当前目录新建Dockerfile）
docker build -t . rabbitmq:new
3.kubernetes配置文件（serviceAccount.yaml、service.yaml、deployment.yaml）
创建serviceAccount，这样autocluster可以通过serviceAccount去访问rabbitmq-service的endpoints
--- apiVersion: v1 kind: ServiceAccount metadata: name: rabbitmq namespace: default --- kind: Role apiVersion: rbac.authorization.k8s.io/v1beta1 metadata: name: endpoint-reader namespace: default rules: - apiGroups: [""] resources: ["endpoints"] verbs: ["get"] --- kind: RoleBinding apiVersion: rbac.authorization.k8s.io/v1beta1 metadata: name: endpoint-reader namespace: default subjects: - kind: ServiceAccount name: rabbitmq roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: endpoint-reader
创建service.yaml
--- apiVersion: v1 kind: Service metadata: labels: app: rabbitmq name: rabbitmq spec: ports: - port: 5672 name: port-5672 targetPort: 5672 protocol: TCP nodePort: 5672 - port: 4369 name: port-4369 targetPort: 4369 protocol: TCP - port: 5671 name: port-5671 targetPort: 5671 protocol: TCP - port: 15672 targetPort: 15672 nodePort: 15672 name: port-15672 protocol: TCP - port: 25672 name: port-25672 targetPort: 25672 protocol: TCP type: NodePort selector: app: rabbitmq
创建deployment.yaml，在此之前需要先生成cookie文件
[root@localhost ~]echo $(openssl rand -base64 32) > erlang.cookie [root@localhost ~]kubectl -n cat create secret generic erlang.cookie --from-file=erlang.cookie
apiVersion: extensions/v1beta1 kind: Deployment metadata: name: rabbitmq spec: replicas: 3 template: metadata: labels: app: rabbitmq spec: containers: - name: rabbitmq image: rabbitmq:new ports: - containerPort: 5672 name: port-5672 - containerPort: 4369 name: port-4369 - containerPort: 5671 name: port-5671 - containerPort: 15672 name: port-15672 - containerPort: 25672 name: port-25672 env: - name: HOSTNAME valueFrom: fieldRef: fieldPath: status.podIP - name: MY_POD_IP valueFrom: fieldRef: fieldPath: status.podIP - name: AUTOCLUSTER_CLEANUP value: "true" - name: RABBITMQ_USE_LONGNAME value: "true" - name: AUTOCLUSTER_LOG_LEVEL value: "debug" - name: CLEANUP_INTERVAL value: "60" - name: CLEANUP_WARN_ONLY value: "false" - name: AUTOCLUSTER_TYPE value: "k8s" - name: LANG value: "en_US.UTF-8" - name: RABBITMQ_ERLANG_COOKIE valueFrom: secretKeyRef: name: erlang.cookie key: erlang.cookie
[root@localhost ~]# kubectl create -f serviceAccount.yaml
[root@localhost ~]# kubectl create -f service.yaml
[root@localhost ~]# kubectl create -f deployment.yaml
启动后出现报错：
若出现节点无法加入集群的问题

部署单节点rabbitmq，使用自带管理界面插件的镜像，在docker hub上搜索rabbitmq，下载镜像docker pull rabbitmq:3.6-management
