一、开发前准备
1. Docker的安装可以参考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
项目结构图
(1) 配置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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>docker-demo</groupId> <artifactId>com.demo</artifactId> <version>1.0-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.2.RELEASE</version> <relativePath /> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <docker.image.prefix>com.demo</docker.image.prefix> <java.version>1.8</java.version> </properties> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.0.0</version> <configuration> <dockerDirectory>src/main/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> <plugin> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <phase>package</phase> <configuration> <tasks> <copy todir="src/main/docker" file="target/${project.artifactId}-${project.version}.${project.packaging}"></copy> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution> </executions> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> </dependencies> </project>
(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
(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
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!
