springboot 学习之路 28(与docker的整合)
在idea中使用docker 一键部署到docker服务器上
在docker服务器上开启2375端口
[ ~]# vim /usr/lib/systemd/system/docker.service 在ExecStart=/usr/bin/dockerd-current 后面加上-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock 重新加载配置文件和启动: systemctl daemon-reload systemctl start docker
在idea中配置docker服务器
修改pom.xml配置文件
<?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> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.huhy</groupId> <artifactId>springboot_docker</artifactId> <version>0.0.1-SNAPSHOT</version> <name>springboot_docker</name> <description>docker部署springboot项目</description> <properties> <java.version>1.8</java.version> <!--properties节点中设置docker镜像的前缀“huhy”--> <docker.image.prefix>huhy</docker.image.prefix> <skipTests>true</skipTests> </properties> <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> </dependencies> <build> <finalName>docker_spring_boot</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <!--加入maven插件“docker-maven-plugin”--> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <!--<version>0.2.3</version>--> <version>1.0.0</version> <executions> <execution> <id>build-image</id> <!--用户只需执行mvn package ,就会自动执行mvn docker:build--> <phase>package</phase> <goals> <goal>build</goal> </goals> </execution> </executions> <configuration> <imageName>${docker.image.prefix}/${project.artifactId}</imageName> <dockerDirectory>src/main/docker</dockerDirectory> <!--指定标签--> <imageTags> <imageTag>latest</imageTag> </imageTags> <!--指定远程 docker api地址--> <dockerHost>http://192.168.248.154:2375</dockerHost> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> </build> </project>
在src/main/docker 下配置Dockerfile文件
FROM java:8 VOLUME /tmp ADD docker_spring_boot.jar app.jar ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
maven ---> package 执行之后既可生成镜像
根据镜像生成容器
测试:
关于docker一键部署很简单,配置方式也有很多,上述是我的配置方式,仅供大家参考,有其他简单的也可以给我留言
