clickhouse operator实际下就是帮助我们自动化的生产一些clickhouse配置文件信息，在目录/etc/clickhouse-server/的config.d conf.d users.d
1.1. 部署clickhouse operateor
下载clickhouse-operator.yaml文件
wget https://raw.githubusercontent.com/Altinity/clickhouse-operator/master/deploy/operator/clickhouse-operator-install-bundle.yaml
文件下载失败可以使用下面的文件 部分镜像可能需要提前下载
提前docker pull下载相关镜像
| altinity/clickhouse-operator：0.23.6 clickhouse/clickhouse-server:24.1.2.5 altinity/metrics-exporter:0.23.6 |
镜像
导出镜像
docker save -o xxx.tar xxx:tag
传输
scp xxx.tar root@192.168.157.xx:/home
导入镜像
docker load --input xxx.tar

stop: &TypeStringBool

description: |
Allows to stop all ClickHouse clusters defined in a CHI.
Works as the following:
- When `stop` is `1` operator sets `Replicas: 0` in each StatefulSet. Thie leads to having all `Pods` and `Service` deleted. All PVCs are kept intact.
- When `stop` is `0` operator sets `Replicas: 1` and `Pod`s and `Service`s will created again and all retained PVCs will be attached to `Pod`s.

Allows to stop all ClickHouse clusters defined in a CHI.
Works as the following:
- When `stop` is `1` operator sets `Replicas: 0` in each StatefulSet. Thie leads to having all `Pods` and `Service` deleted. All PVCs are kept intact.
- When `stop` is `0` operator sets `Replicas: 1` and `Pod`s and `Service`s will created again and all retained PVCs will be attached to `Pod`s.

Liveness and Readiness probes are disabled as well.

部署clickhouse-operator
kubectl apply -f clickhouse-operator.yaml
默认部署在kube-system中
3.2. 部署clickhouse
注意几个配置的地方
zookeeper：填写zookeeper的host信息
users：可以自定义用户信息
cluster：定义集群信息 最简单的方式是直接使用shardsCount和replicaCount定义副本数量和分配数量
clickhouse-operator有一套自定义的命名规则 参考官网文档GitCode - 全球开发者的开源社区,开源代码托管平台

执行插入数据测试
发现数据是一致的
3.3. 分布式存储
修改分区和分片分别为2
3.3.1. 自定义用户
operator提供灵活的标签来创建自定义用户（默认的default用户用于内部分布式查询）
3.3.2. 建表
定义了用户后 可以使用dbeaver操作数据库
四个节点都成功创建表 进行插入数据测试
如果直接在dbeaver中执行插入 发现 1-1-0和其副本1-0-0插入了32条数据 但是0-0-0和o-1-o没有数据 这说明clickhouse没有进行分片存储 这是因为clickhouse 需要借助分布式表来进行分布式存储
create table test on CLUSTER 'ck-cluster2'(
id UInt32,
sku_id String,
total_amount Decimal(16,2),
create_time Datetime
) engine =ReplicatedMergeTree
partition by toYYYYMMDD(create_time)
primary key (id)
order by (id,sku_id);
CREATE TABLE distributed_table on cluster 'ck-cluster'
ENGINE = Distributed('ck-cluster', 'default', 'test_distribute', rand());后续所有操作都操作分布式表 分布式表不存储数据
查询后可以发现数据
再分别观察不同分片上的数据
0分片上有13条数据
1分片上有19条数据
