RabbitMQ单机&可能遇到的问题

1.Deployments

 1 kind: Deployment
 2 apiVersion: apps/v1
 3 metadata:
 4   name: rabbitmq-deployment
 5 spec:
 6   replicas: 1
 7   selector:
 8     matchLabels:
 9       app: rabbitmq10   template:
11     metadata:
12       creationTimestamp: null
13       labels:
14         app: rabbitmq15     spec:
16       volumes:
17         - name: host-time
18           hostPath:
19             path: /etc/localtime
20             type: ''
21       containers:
22         - name: rabbitmq
23           image: rabbitmq
24           ports:
25             - containerPort: 5672
26               protocol: TCP
27             - containerPort: 15672
28               protocol: TCP
29           resources: {}
30           volumeMounts:
31             - name: host-time
32               readOnly: true
33               mountPath: /etc/localtime
34           lifecycle:
35             postStart:
36               exec:
37                 command:
38                   - /bin/bash
39                   - '-c'
40                   - >-
41                     echo management_agent.disable_metrics_collector = false >
42                     /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf
43                     && rabbitmq-plugins enable rabbitmq_management

2.可能遇到的问题

1. 1. Stats in management UI are disabled on this node

1 docker exec -it {rabbitmq容器名称或者id} rabbitmq-plugins enable rabbitmq_management
2 
3 #重启rabbitmq容器
4 docker retart {rabbitmq容器id}

　　　　　　2.无法进入管理员操作界面 

#进入rabbitmq容器
docker exec -it {rabbitmq容器名称或者id} /bin/bash

#进入容器后，cd到以下路径
cd /etc/rabbitmq/conf.d/

#修改 management_agent.disable_metrics_collector = false
echo management_agent.disable_metrics_collector = false > management_agent.disable_metrics_collector.conf

#退出容器
exit

#重启rabbitmq容器
docker retart {rabbitmq容器id}

　　　　　　上述2个问题可以在Deployment中通过容器启动后命令完成

 1 　　　　　　lifecycle:
 2             postStart:
 3               exec:
 4                 command:
 5                   - /bin/bash
 6                   - '-c'
 7                   - >-
 8                     echo management_agent.disable_metrics_collector = false >
 9                     /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf
10                     && rabbitmq-plugins enable rabbitmq_management
