1.Docker安装
可以参考:
https://docs.docker.com/install/
2.配置docker远程连接端口
vi /usr/lib/systemd/system/docker.service
找到 ExecStart,在最后面添加 -H tcp://0.0.0.0:2375,如下图所示

3.重启docker
systemctl daemon-reload
systemctl start docker
4.开放端口
firewall-cmd --zone=public --add-port=2375/tcp --permanent
5.Idea安装插件,重启

6.连接远程docker
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
二、新建项目
1.创建springboot项目

1、配置pom文件
<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">

2、在src/main目录下创建docker目录,并创建Dockerfile文件
FROM openjdk:8-jdk-alpine
ADD *.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
3、在resource目录下创建application.properties文件
logging.config=classpath:logback.xml
logging.path=/home/developer/app/logs/
server.port=8990
4、创建DockerApplication文件
@SpringBootApplication
public class DockerApplication {
public static void main(String[] args) {
SpringApplication.run(DockerApplication.class, args);
}
}
5、创建DockerController文件
@RestController
public class DockerController {
static Log log = LogFactory.getLog(DockerController.class);
@RequestMapping("/")
public String index() {
log.info("Hello Docker!");
return "Hello Docker!";
}
}
6、增加配置
命令解释:
Image tag : 指定镜像名称和tag,镜像名称为 docker-demo,tag为1.1
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。
7、Maven打包
8、运行
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
![](https://filescdn.proginn.com/1147e32891d518ecf618c96788568678/9cbffc8579a5571b13dc6557cb665ad0.webp)
这里我们可以看到镜像名称为docker-demo:1.1,docker容器为docker-server
9、运行成功
10、浏览器访问

11、日志查看

自此,通过IDEA 部署springboot项目到docker成功!难以想象,部署一个Javaweb项目竟然如此简单方便!
