我正在部署一个具有3个副本的NodeJS服务器，并连接到Redis以使用Sub/Pub功能

NodeJS:

const redis = require('redis');
const REDISPORT = 6379;
const subscriber = redis.createClient(REDISPORT, 'redis-service.default.svc.cluster.local');
const publisher = redis.createClient(REDISPORT, 'redis-service.default.svc.cluster.local');

尝试了几个小时，最后修复了它。当我创建kustomization.yml时，这是一个小错误。因此，基本上与Redis或NodeJS无关

以前的错误文件：kustomization.yml:

const redis = require('redis');
const REDISPORT = 6379;
const subscriber = redis.createClient(REDISPORT, 'redis-service.default.svc.cluster.local');
const publisher = redis.createClient(REDISPORT, 'redis-service.default.svc.cluster.local');

我把CommonLabel放在这里，kustomize覆盖了我的Redis标签，导致了网络错误

这是因为我在redis pod中也使用了“应用程序标签”
新文件：kustomization.yml:

const redis = require('redis'); const REDISPORT = 6379; const subscriber = redis.createClient(REDISPORT, 'redis-service.default.svc.cluster.local'); const publisher = redis.createClient(REDISPORT, 'redis-service.default.svc.cluster.local');
