我正在使用此图表:https://github.com/helm/charts/tree/master/stable/rabbitmq在 Kubernetes 上部署 3 个 RabbitMQ 节点的集群。我的目的是将所有队列镜像到集群中的 2 个节点内。

这是我用来运行 Helm 的命令:helm install --name rabbitmq-local -f rabbitmq-values.yaml stable/rabbitmq
这是rabbitmq-values.yaml的内容:

persistence: 
  enabled: true 
 
resources: 
  requests: 
    memory: 256Mi 
    cpu: 100m 
 
replicas: 3 
 
rabbitmq: 
  extraConfiguration: |- 
    { 
      "policies": [ 
        { 
          "name": "queue-mirroring-exactly-two", 
          "pattern": "^ha\.", 
          "vhost": "/", 
          "definition": { 
            "ha-mode": "exactly", 
            "ha-params": 2 
          } 
        } 
      ] 
    }

请您参考如下方法:

根据https://github.com/helm/charts/tree/master/stable/rabbitmq#load-definitions , 可以链接 JSON配置为 extraConfiguration .所以我们最终得到了这个有效的设置:

rabbitmq-values.yaml:

rabbitmq: 
  loadDefinition: 
    enabled: true 
    secretName: rabbitmq-load-definition 
  extraConfiguration: 
    management.load_definitions = /app/load_definition.json 

apiVersion: v1 
kind: Secret 
metadata: 
  name: rabbitmq-load-definition 
type: Opaque 
stringData: 
  load_definition.json: |- 
    { 
      "vhosts": [ 
        { 
          "name": "/" 
        } 
      ], 
      "policies": [ 
        { 
          "name": "queue-mirroring-exactly-two", 
          "pattern": "^ha\.", 
          "vhost": "/", 
          "definition": { 
            "ha-mode": "exactly", 
            "ha-params": 2 
          } 
        } 
      ] 
    }
