+ 基础操作

```shell
mkdir redis-operator && cd redis-operator

operator-sdk init --domain ifbiu.com --plugins=helm

operator-sdk create api --group app --version v1 --kind Redis --helm-chart-repo http://charts.bitnami.com/bitnami --helm-chart redis

# 如果没有redis目录，用helm pull去拉一个
cd  helm-charts/redis/ && helm dependencies build

# 重新执行 create api
operator-sdk create api --group app --version v1 --kind Redis --helm-chart-repo http://charts.bitnami.com/bitnami --helm-chart ./helm-charts/redis

# 打包并上传到docker hub
make docker-build docker-push IMG="ifbiu/redis-operator:v0.0.1"

# 部署到crd
make deploy IMG="ifbiu/redis-operator:v0.0.1"

#  部署生成的manifest
kubectl apply -f config/samples/app_v1_redis.yaml

# 加权限，加完重启pod
kubectl create clusterrolebinding redis-operator-cluster-admin --serviceaccout=redis-operator-system:redis-operator-controller-manager --clusterrole=cluster-admin

# 卸载
