Docker学习(四)-Spring Boot on Docker
1.创建spring boot项目
pom.xml文件新增docker支持
<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> <imageName>${docker.image.prefix}/${project.artifactId}</imageName> <dockerDirectory>src/main/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> </build>
<properties>
<java.version>1.8</java.version>
<docker.image.prefix>springboot</docker.image.prefix>
</properties>
添加swagger支持
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.5.0</version> </dependency> <!-- swagger-ui --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.5.0</version> </dependency>
开启swagger,并创建测试控制器
@EnableSwagger2 @SpringBootApplication public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
@Controller @RequestMapping(value = "/test") public class TestController { @RequestMapping(value = "/fun", method = RequestMethod.GET) @ResponseBody public String fun(@RequestParam(name = "str") String str) { String hostAddress = ""; try { InetAddress address = InetAddress.getLocalHost();//获取的是本地的IP地址 hostAddress = address.getHostAddress(); } catch (Exception ex) { } return hostAddress + "返回:" + str; } }
2.docker开始部署springBoot项目
进入发布服务器,创建目录,并新建Docker编译支持,Dockerfile文件
# From java image, version : 8 #指定镜像,这里用网易云仓库的java8镜像 FROM hub.c.163.com/library/java:8-jre # 挂载test-docker目录 VOLUME /tmp # COPY or ADD to image COPY example.dockertest-0.0.1-SNAPSHOT.jar app.jar ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
使用Docker创建镜像
docker build -t service-test .
-t代表要构建的镜像的tag
.代表当前目录,也就是Dockerfile所在的目录。
查看镜像列表
运行镜像并测试是否成功
docker run -d -p 8081:8080 service-test
curl http://192.168.50.23:8080/test/fun?str=aaa curl http://192.168.50.23:8081/test/fun?str=aaa curl http://192.168.50.23:8082/test/fun?str=aaa
将镜像文件上传docker镜像服务器,私有镜像服务器搭建参见 https://www.cnblogs.com/woxpp/p/11871886.html
docker tag service-test 192.168.50.24:5000/service-test:latest docker push 192.168.50.24:5000/service-test:latest
拉取进行并启动
测试是否可用
