+# Docker本地测试部署
+Docker部署到本地，仅提供本地测试，请勿在生产环境直接使用！如需生产环境使用，请自己重新定制。
+
+## 部署准备
+在直接使用Docker部署前，需要准备Docker环境以及修改相关配置。
+
+### Docker及Docker compose安装
+部署需安装Docker，Docker compose请自行参考[官网](https://docs.docker.com/install/)。
+
+### 前端配置
+参考[部署指南](DEPLOY.md)将项目打包编译，修改dist/static/site-map.js如下： 
+```js
+(function () {
+  window.API = {
+    'CESHI_API_HOST': '127.0.0.1:10615'
+  }
+  Object.freeze(window.API)
+  Object.defineProperty(window, 'API', {
+    configurable: false,
+    writable: false
+  })
+})()
+```
+### 后端配置
+后端不需要任何配置，只需要到sia-task-build-component和sia-task-executor-demo下均执行
+> mvn clean install
+
+或者直接在项目根目录下运行：
+> mvn clean install
+
+**【注意】**：   
+在sia-task-executor-demo中执行之前，需要先确认sia-task-hunter的版本，即maven打包时激活的profile。    
+去修改sia-task-executor-demo的pom文件，修改如下：
+```xml
+        <dependency>
+            <groupId>com.sia</groupId>
+            <artifactId>sia-task-hunter</artifactId>
+            <version>1.0.0</version>
+            <!-- 你激活的maven profile产生的classifier-->
+            <classifier>jdk18</classifier>
+        </dependency>
+```
+### 运行
+在项目根目录下运行：
+>  docker-compose -f docker-compose-zk.yml up -d
+>  docker-compose -f docker-compose-mariadb.yml up -d
+
+因为zk和数据库运行后需要一段时间进行选举和初始化,另外可能碰到zk某个节点启动失败，需要重新启动（运行[关闭](#close)命令再重新运行启动命令），稍微等待一会再运行
+>  docker-compose -f docker-compose-sia.yml up -d
+
+等待运行成功后，即可通过127.0.0.1:9999访问管理页面。
+
+### 关闭{#close}
+依次运行如下命令：
+> docker-compose -f docker-compose-sia.yml down 
+
+> docker-compose -f docker-compose-zk.yml down    
+
+> docker-compose -f docker-compose-zk.yml down  
+
+### 调试
+所有java项目已经配置远程调试端口，按下面说明配置端口即可远程调试。
+
+### 说明
+所有项目均在docker中运行，访问地址均为127.0.0.1，端口如下：
+
+|项目|远程调试端口|访问端口|
+|:---:|:---:|:---:|
+|display|--|9999|
+|config|9109|10615|
+|scheduler|9209|19011|
+|demo|9309|10089|
+|db|3306|3306|
+|zk1|--|2181|
+|zk2|--|2182|
+|zk3|--|2183|
+
+前端项目，将前端打包的代码以及nginx配置挂载成了卷。其他项目未挂载任何卷。
