我删除了helm redis chart，重新部署ks-installer。这次有redis服务了，但是redis初始化容器有报错

Could not connect to Redis at redis-ha:26379: Name does not resolve
Initializing config..
/readonly-config/init.sh: line 84: Could not resolve the announce ip for this pod: not found

看起来是没有announce服务@Cauchy

看下pod状态 redis-ha起来了么 有redis-ha这个service么？

        leo 你之前安装高可用成功过么

          没有，我的测试集群是单master，这是第一次在多master集群部署@Jeff

            没法远程，这是内网集群

              leo kubectl run -it --rm test --image=alpine:3.7 --restart=Never -n kubesphere-system -- sh -c "ping redis-ha" 试试能不能解析到redis-ha

              • leo 回复了此帖

                  Cauchy

                  $ kubectl run -it --rm test --image=alpine:3.7 --restart=Never -n kubesphere-system -- sh -c "ping redis-ha"
ping: bad address 'redis-ha'
pod "test" deleted
pod kubesphere-system/test terminated (Error)

                    Cauchy 我用那个命令测了一下我的单master集群，也是解析失败。但是那个集群成功部署了

                      单master集群的redis跟这个不一样

                      • leo 回复了此帖

                        Cauchy 我在pod内ping每个svc都通，但是ping redis-ha不通，如果dns配置有问题，那应该每个svc都Ping不通吧。请问这个有什么好的调试建议吗

                          不是dns问题，我在ks-installer的redis-ha目录执行helm template导出了一份yaml，手动apply这个yaml以后有了announce服务。然后修改了一下redis的selector。不过现在没有使用haproxy。暂时可以使用了Cauchy @Jeff

                            也可以看下是不是clusterName修改了，我是修改成其他的redis起不来，改回cluster.local就可以了，时间比较紧也没时间去排查具体问题是啥
