首先使用helm charts进行尝试，太不好使了，首先chart比较老，根本跑步起来，于是使用operator进行部署. 首先学习operator，然后安装operator.
最后跑的pod如下：
default pod/druid-operator-85648779d7-hbhjh 1/1 Running 0 19d

安装记录：
- 先在k8s部署operator的pod:
* kgaa -l name=druid-operator
NAMESPACE NAME READY STATUS RESTARTS AGE
default pod/druid-operator-85648779d7-hbhjh 1/1 Running 0 19d
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default service/druid-operator-metrics ClusterIP 10.254.203.115 <none> 8383/TCP,8686/TCP 19d
NAMESPACE NAME DESIRED CURRENT READY AGE
default replicaset.apps/druid-operator-85648779d7 1 1 1 19d
这里遇到一个有rs，但是没有pod的问题，忘记怎么解决的了。。。。。。印象里改了改，然后重新create就好了。以后真得时刻记录
- 安装druid：
官网的实例yaml，只是能跑，broker都没有。找了很多资料，最后凑出来一个能跑的。
路上遇到的坑：
- 新版的operator/overlord的配置挪到一个目录了，配置出错，log打不出来，改一下目录就好了
- console显示restricted mode是因为哪没通，最终都跑通了，所有的按钮就好了
- router没有ingress，需要自己建立ingress，router才能出来
- metadata如果使用derby的话，不好使，最后申请了个mysql，最终跑起来了, indexer也要改为使用metadata
- 官网没有druid-mysql镜像，按照官网步骤需要自己编一个，用dockerhub autobuild ARG传不进去，我自己编了个镜像
https://hub.docker.com/repository/docker/leiking/druid-mysql，这个dockerfile完美的展示了，如何在一个已有的镜像里，添加东西，老外真牛 - 权限问题，我最终都改为0了，否则建不了data目录，会报错
- 我把service从None改为有ip了，当初调试时弄得，感觉不用ip也行
相关异常log
Error in custom provider, org.apache.druid.java.util.common.RE: server initialization exception
1) Unknown provider[localdruid.host=172.10.73.7] of Key[type=org.apache.druid.indexing.overlord.TaskStorage, annotation=[none]], known options[[local, metadata]]
- 有一台虚机的flannel配置错了，导致dns解析不到，运维改了，重启flannel后，最终跑起来了
需要调整query为second，就行了
注意 select必须带所有group的东西
SELECT "name", "unique_name", "lmds_description", FLOOR(__time to MINUTE) AS Mi, SUM("count") AS c
FROM "ss-publish1"
WHERE "__time" >= CURRENT_TIMESTAMP - INTERVAL '1' DAY AND "lmds_description" != 'Url expired!'
GROUP BY 1,2,3,4 ORDER BY c DESC
production mode 好像是需要自己做用户和密码，把development 的init 后面的挪过去就好了。
