1、把要部署的功能打成jar
工程目录结构
pom文件
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.oy</groupId>
<artifactId>test_docker</artifactId>

IndexController.java
/**
* @author oy
* @version 1.0
* @date 2019年11月11日
* @time 上午2:18:09
*/
@Controller
public class IndexController { @RequestMapping("test")
public String test() {
return "test";
}
}
clean install -DskipTests将工程打成jar包，改名为test_docker.jar。
将test_docker.jar上传到linux的指定目录, 比如/root/mydocker/test_docker。
2、准备工作
docker pull mcr.microsoft.com/java/jdk:8u192-zulu-alpine
3、编写Dockerfile
FROM mcr.microsoft.com/java/jdk:8u192-zulu-alpine
MAINTAINER oy COPY test_docker.jar /usr/local/app.jar # 执行java -jar命令（CMD：在启动容器时才执行此行。RUN：构建镜像时就执行此行）
CMD java -jar /usr/local/app.jar # 设置对外端口为8080
EXPOSE 8080
4、docker build
docker build -f /root/mydocker/test_docker/Dockerfile -t oy/test_docker:1.1 .
5、docker run
docker run -it -p 8080:8080 oy/test_docker:1.1
6、访问
