有ks-redis 改过副本数或者删过redis吗？看下redis-ha（sts）和redis-ha-haproxy（deploy）的副本数都调到3

Lleo · 2020年2月17日

之前部署完失败后曾经删除过ks-redis，ks-redis这个chart可能是没有删除干净。kubesphere-system命名空间看不到任何redis服务。

Cauchy · 2020年2月17日

要删除的话用helm del --purge ks-redis 然后重启下ks-installer

Lleo · 2020年2月17日

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

Cauchy · 2020年2月18日

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

Lleo · 2020年2月18日

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

Cauchy · 2020年2月18日

leo 发个远程瞧瞧

Lleo · 2020年2月18日

没法远程，这是内网集群

Cauchy · 2020年2月18日

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

Lleo · 2020年2月18日

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 · 2020年2月18日

解析不到的话应该是集群的dns有问题
可以先参考下这个：https://github.com/kubesphere/ks-installer/issues/33

Lleo · 2020年2月18日

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

Cauchy · 2020年2月18日

单master集群的redis跟这个不一样

Lleo · 2020年2月18日

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
