# idea远程连接docker，一键部署

一、开发前置要求:

```
1.docker
2.docker配置过远程连接
```

### 1.idea安装docker插件

### 2.

1）、编辑配置 2）、填远程docker地址 3）、连接成功，会列出远程docker容器和镜像 ![在这里插入图片描述](https://img-blog.csdnimg.cn/52ee2adf7d24446aa0869fb898c0d16a.png?x-oss-process=image/watermark,type_d3F5LXplbmhlaQ,shadow_50,text_Q1NETiBA6L-b5Ye755qE56iL5bqP54y_fg==,size_20,color_FFFFFF,t_70,g_se,x_16) 连接成功，会列出远程docker容器和镜像 ![在这里插入图片描述](https://img-blog.csdnimg.cn/86bdf3f2828248978a88462feb47b610.png?x-oss-process=image/watermark,type_d3F5LXplbmhlaQ,shadow_50,text_Q1NETiBA6L-b5Ye755qE56iL5bqP54y_fg==,size_13,color_FFFFFF,t_70,g_se,x_16)

## 二、新建项目

1.创建springboot项目 项目结构图 ![在这里插入图片描述](https://img-blog.csdnimg.cn/0a9441bfb447465e938cf42736c8c279.png?x-oss-process=image/watermark,type_d3F5LXplbmhlaQ,shadow_50,text_Q1NETiBA6L-b5Ye755qE56iL5bqP54y_fg==,size_9,color_FFFFFF,t_70,g_se,x_16)

### step1、配置pom文件

```java
<?xml version="1.0" encoding="UTF-8"?>  
<project xmlns="http://maven.apache.org/POM/4.0.0"  
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                    <include>${project.build.finalName}.jar</include>  
                </resource>  
              </resources>

                    <goals>

12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273747576777879
```

### step2、在src/main目录下创建docker目录，并创建Dockerfile文件

```java
FROM openjdk:8-jdk-alpine  
ADD *.jar app.jar  
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]  
123
```

### step3、在resource目录下创建application.properties文件

```java
logging.config=classpath:logback.xml  
logging.path=/home/developer/app/logs/  
server.port=8990
123
```

### step4、创建DockerApplication文件

```java
@SpringBootApplication  
public class DockerApplication {  
    public static void main(String[] args) {  
        SpringApplication.run(DockerApplication.class, args);  
    }  
}  
123456
```

### step5、创建DockerController文件

```java
@RestController  
public class DockerController {  
    static Log log = LogFactory.getLog(DockerController.class);  
  
    @RequestMapping("/")  
    public String index() {  
        log.info("Hello Docker!");  
        return "Hello Docker!";  
    }  
}  
12345678910
```

### step6、增加配置

![在这里插入图片描述](https://raw.githubusercontent.com/qkd90/figureBed/main/202304181128057.png) 命令解释： Image tag : 指定镜像名称和tag，镜像名称为 docker-demo，tag为v1.0.0 Bind ports : 绑定宿主机端口到容器内部端口。格式为\[宿主机端口]:\[容器内部端口] Bind mounts : 将宿主机目录挂到到容器内部目录中。格式为\[宿主机目录]:\[容器内部目录]。 这个springboot项目会将日志打印在容器 /home/developer/app/logs/ 目录下，将宿主机目录挂载到容器内部目录后，那么日志就会持久化容器外部的宿主机目录中。

**该配置等同于执行命令**：

```shell
docker build -t v1.0.0 . && docker run -p 8080:8080 -v /home/developer/app/logs/:/home/developer/app/logs/ --name docker-hello v1.0.0 
```

### step7、Maven打包

![在这里插入图片描述](https://raw.githubusercontent.com/qkd90/figureBed/main/202304181128523.png)

### step8、运行

![在这里插入图片描述](https://raw.githubusercontent.com/qkd90/figureBed/main/202304181128570.png) 先pull基础镜像，然后再打包镜像，并将镜像部署到远程docker运行 ![在这里插入图片描述](https://img-blog.csdnimg.cn/7137ec0f794049e3937ddc24fdb4c796.png?x-oss-process=image/watermark,type_d3F5LXplbmhlaQ,shadow_50,text_Q1NETiBA6L-b5Ye755qE56iL5bqP54y_fg==,size_13,color_FFFFFF,t_70,g_se,x_16)

这里我们可以看到镜像名称为docker-demo:1.1，docker容器为docker-server

![image-20230418114953297](https://raw.githubusercontent.com/qkd90/figureBed/main/202304181149348.png)

添加maven goal清理不要的包

```
clean package -U -DskipTests
```

### step9、运行成功

![图片](https://raw.githubusercontent.com/qkd90/figureBed/main/202304181128732.png) 自此，通过IDEA 部署springboot项目到docker成功！可以在浏览器进行应用访问。难以想象，部署一个Javaweb项目竟然如此简单方便！
