$ export NAMESPACE="mysql-test"
$ kubectl create namespace $NAMESPACE
$ kubectl -n $NAMESPACE create deploy/crds/lemonmysql_v1alpha1_mysql_crd.yaml
$ kubectl -n $NAMESPACE create deploy/service_account.yaml
$ kubectl -n $NAMESPACE create deploy/role.yaml
$ kubectl -n $NAMESPACE create deploy/role_binding.yaml

2. Deploy operator pod

$ kubectl -n $NAMESPACE create -f deploy/operator.yaml
$ kubectl -n $NAMESPACE get deployment
NAME               DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
mysql-operator     1         1         1            1           1m

3.Create a mysql CR

$ kubectl -n $NAMESPACE apply -f deploy/crds/lemonmysql_v1alpha1_mysql_cr.yaml
$ kubectl -n $NAMESPACE get mysql
NAME            AGE
example-mysql   20m
$ kubectl -n $NAMESPACE get mysql -o yaml
