 # dolphinscheduler-operator
 
-## feature
+## Features
 
-1. deployment the master ,worker moudle
-2. scale the pods numbers with one commond
-3. update the master,worker version  quickly (not include the sql)
+- Deploy and manage the master, worker, alert, api components.
+- Scale the Pod numbers with one commond.
+- Update the component's version (not include the database schema).
 
 ## Project Status
 
-**Project status:** *'alpha1'*
+Project status: `alpha1`
 
-**Current API version:** *`v1alpha1`*
-
-## Prerequisites
-
-**go version :** *go1.17.6*
-
-**minikube version:** *v1.25.1*
-
-**kubebuilder version:** *3.3.0*
-
-**kubectl version:** *1.23.1*
+Current API version: `v1alpha1`
 
 ## Get Started
 
-1. **create  namespace ds**
+- Create a namespace `ds`
 
-    kubectl create namespace ds
+```shell
+kubectl create namespace ds
+```
 
-2. **install  postgres (not required)**
+- Install PostgreSQL database (Optional)
 
-    if had no postgressql ,you can turn into config/ds/ and run *"kubectl apply -f postgreSQL/"* ,but you need to replace your local document to hostPath.path in postgres-pv.yaml first
+If you don't have a running database, you can run `kubectl apply -f config/ds/postgreSQL`
+to create a demo database, note that this is only for demonstration, DO NOT use it in production environment.
+You need to replace the `hostPath.path` in `postgres-pv.yaml` if you don't have a directory `/var/lib/data`.
 
-    connect to postgressql and run the sql script in  dolphinscheduler/dolphinscheduler-dao/resources/sql
+Connect to PostgreSQL and initialize the database schema by executing
+[`dolphinscheduler/dolphinscheduler-dao/src/main/resources/sql/dolphinscheduler_postgresql.sql`](https://github.com/apache/dolphinscheduler/blob/dev/dolphinscheduler-dao/src/main/resources/sql/dolphinscheduler_postgresql.sql).
 
-    record the deployment ip  eg: 172.17.0.3
+- Install zookeeper (Optional)

+If you don't have a running zookeeper, the demo doployment file is in `config/ds/zookeeper`,
+run `kubectl apply -f config/ds/zookeeper`.
 
+- Create pv and pvc (Optional)
 
-3. **install  zookeeper(not required)**
+If you have pv and pvc, you can config it in `config/sameples`.
 
-    if had no zookeeper ,the doployment file is in config/ds/zookeeper ,run *"kubectl apply -f zookeeper/"* and record the ip ,eg :172.17.0.4
+Or you can create it with `config/ds/ds-pv.yaml` and `config/configmap/ds-pvc.yaml`.
+Notice to replace the `hostPath.path` in `ds-pv.yaml`.
 
+And you can mount the lib in dolphinscheduler `/opt/soft`  in config/samples/ds_v1alpha1_dsworker.yaml with paramter named lib_pvc_name
 
-4. **create pv and pvc (not required)**
+Mount the logs in `/opt/dolphinscheduler/logs` with the pvcname named `log_pvc_name`.
 
-    if you had pv and pvc ,you can config it in config/sameples
+## how to test
 
-    or you can create it with config/ds/ds-pv.yaml and config/configmap/ds-pvc.yaml .notice to replace your local document address in hostPath.path in ds-pv.yaml
+* Replace the database config and zookeeper config paramters in [`config/samples/`](./config/samples/).
 
-    and you can mount the lib in dolphinscheduler /opt/soft  in config/samples/ds_v1alpha1_dsworker.yaml with paramter named lib_pvc_name
+* Replace the nodeport in [`config/samples/ds_v1alpha1_api.yaml`](./config/samples/ds_v1alpha1_dsapi.yaml)
 
-    mount the logs in /opt/dolphinscheduler/logs with the paramters named log_pvc_name with pvcname
+* Install CRDs and controller
 
- ## how to test
+```shell
+export IMG=ghcr.io/apache/dolphinscheduler-operator:latest
+make build && make manifests && make install && make deploy
+```
 
- * replace the database config and zookeeper config paramters in config/samples/*.yaml
+* Deploy the sample
 
- * replace the nodeport in *config/samples/ds_v1alpha1_api.yaml*
-
- * in current project  run *"make build && make manifests && make install && make run"*
-
- * cd to config/samples
-
- * first run *"kubectl apply -f ds_v1alpha1_dsalert.yaml "*
-
- * then run  *"kubectl apply -f ds_v1alpha1_api.yaml -f ds_v1alpha1_dsmaster.yaml -f ds_v1alpha1_dsworker.yaml "*
-
- ## the result

+```shell
+cd config/samples
+kubectl apply -f ds_v1alpha1_dsalert.yaml
+kubectl apply -f ds_v1alpha1_api.yaml -f ds_v1alpha1_dsmaster.yaml -f ds_v1alpha1_dsworker.yaml
