TiDB 默认会使用很多文件描述符，工作节点和上面的 Docker 进程的 ulimit 必须设置大于等于 1048576：

[root@master /]# sudo vim /etc/security/limits.conf

root            soft    nofile          1048576
root            hard    nofile          1048576

创建命名空间

[root@master simple]# cat 0-tidb-namespace.yaml
apiVersion: v1
kind: Namespace
metadata:
  name: tidb
  labels:
    xincan.kubernetes.io/company: xincan.cn
    xincan.kubernetes.io/version: 0.0.1
    xincan.kubernetes.io/product: component
[root@master simple]#

创建CRD

wget https://raw.githubusercontent.com/pingcap/tidb-operator/master/manifests/crd.yaml

[root@master simple]# kubectl apply -f 1-tidb-crd.yaml

部署operator

[root@master /]# helm install --namespace tidb tidb-operator pingcap/tidb-operator --version v1.2.1 \
    --set operatorImage=registry.cn-beijing.aliyuncs.com/tidb/tidb-operator:v1.2.1 \
    --set tidbBackupManagerImage=registry.cn-beijing.aliyuncs.com/tidb/tidb-backup-manager:v1.2.1 \
    --set scheduler.kubeSchedulerImageName=registry.aliyuncs.com/google_containers/kube-scheduler
