本文档介绍了如何通过 Kubernetes 集群，快速部署 TiDB Operator，并使用 TiDB Operator 部署 TiDB 集群。一步步操作能快速搭建一个基于容器的TiDB集群，并通过在搭建过程中出现的问题进行快速解答，力争通过该文档能进行一个快速的入门，由浅及深，保证100%搭建成功，作为一个入门级别的标准安装文档使用。
部署TiDB Operator
下载TiDB Cluster CRD部署文件
wget https://raw.githubusercontent.com/pingcap/tidb-operator/master/manifests/crd.yaml
创建TiDB Cluster CRD
kubectl apply -f crd.yaml
customresourcedefinition.apiextensions.k8s.io/tidbclusters.pingcap.com created
customresourcedefinition.apiextensions.k8s.io/backups.pingcap.com created
customresourcedefinition.apiextensions.k8s.io/restores.pingcap.com created
customresourcedefinition.apiextensions.k8s.io/backupschedules.pingcap.com created
customresourcedefinition.apiextensions.k8s.io/tidbmonitors.pingcap.com created
customresourcedefinition.apiextensions.k8s.io/tidbinitializers.pingcap.com created
customresourcedefinition.apiextensions.k8s.io/tidbclusterautoscalers.pingcap.com created
检查CRD状态
[root@k8s-master ~]# kubectl get crd |grep ping

安装配置TiDB Operator
方法一：通过yaml
下载TiDB Operator的docker iamge
docker pull pingcap/tidb-operator:v1.1.7
docker pull pingcap/tidb-backup-manager:v1.1.7
docker pull pingcap/advanced-statefulset:v0.3.3
mkdir -p /opt/soft/docker-image
docker save -o tidb-backup-manager.tar pingcap/tidb-backup-manager
docker save -o tidb-operator.tar pingcap/tidb-operator
docker save -o advanced-statefulset.tar pingcap/advanced-statefulset
创建tidb-operator部署文件

[root@r21 soft]# kubectl create namespace tidb-admin
## create tidb-operator
[root@r21 soft]# kubectl apply -f tidb-operator-deploy.yaml -n tidb-admin

1、创建pv
mount --bind /home/data/data1/ /home/data/data1/
mount --bind /home/data/data2/ /home/data/data2/
mount --bind /home/data/data3/ /home/data/data3/
为TiDB Cluster创建PV
创建PV有两种方式：一种是人工管理 PV 的方式就叫作 Static Provisioning；另一种是Dynamic Provisioning动态创建存储卷，动态供给的关键就是StorageClass，它的作用就是创建PV模板。目前最常用的是Local PV，可使用 local-static-provisioner 项目中的 local-volume-provisioner 程序创建本地存储对象
方式一：人工管理Static Provisioning方式
创建PV
1、在不同的work节点上创建不同的目录，有几个计算节点分别在节点上执行
for i in `seq 9`; do mkdir -p /home/data/pv0$i; done
2、在K8S的master节点上执行创建pv的语句.
[root@r22 disks]# for i in `seq 9`; do
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: PersistentVolume
metadata:
name: tidb-cluster-r22-pv0${i}

tidb-cluster-r23-pv08 5Gi RWO Delete Available local-storage 32s
tidb-cluster-r23-pv09 5Gi RWO Delete Available local-storage 32s
方法二、通过local-volume-provisioner
准备本地存储
##依次在K8S的各个计算节点依次执行
1、创建对应的目录
mkdir /home/data/{data1,data2,data3}
2、依次挂载对应的节点
mount --bind /home/data/data1/ /home/data/data1/
mount --bind /home/data/data2/ /home/data/data2/
mount --bind /home/data/data3/ /home/data/data3/
###
上述的/home/data/data1、/home/data/data2、/home/data/data13是 local-volume-provisioner
使用的发现目录（discovery directory），local-volume-provisioner 会为发现目录下的每一个
子目录创建对应的 PV
下载和配置 local-volume-provisioner
1、下载
wget https://raw.githubusercontent.com/pingcap/tidb-operator/master/examples/local-pv/local-volume-provisioner.yaml
2、修改不同的路径。如果你使用与上一步中不同路径的发现目录，需要修改 ConfigMap 和 DaemonSet 定义。
#cat local-volume-provisioner.yaml

部署和检查 local-volume-provisioner 程序.
部署完成之后会在挂载点创建对应的PV
1、部署

总结：
通过该步骤一步步的进行搭建tidb集群容器化，后续会逐步更新一个其他的组件及相关的文章。
