Question

我在Kubernetes中部署了带bitnami / redis-cluster图表的Redis集群。我使用redis-cluster npm包从nodejs连接到集群。建立连接后，我尝试连续设置数千个键。完成所有过程的时间预计为十分钟。但是在连接两分钟后，Redis连接断开。

连接是否有问题，我该怎么办？就像更改配置或进行其他操作一样。

在我的场景或常见场景中，失去连接的确切原因是什么？

我的代码：

const redis = require('redis');
const redisCluster = require('redis-clustr')
const redisClient = new redisCluster({
    servers: [
    { host: "IP", port: 6379 },
    { host: "IP", port: 6379 }, 
    { host: "IP", port: 6379 },  
    { host: "IP", port: 6379 },
    { host: "IP", port: 6379 }, 
    { host: "IP", port: 6379 } 
     ],
    createClient: (port, host) => {
      return redis.createClient({ 
       port,
       host,
       auth_pass: 'PASSWORD',
     });
   }
});
