摘要:登录网站,生成一个基本的应用。将应用导入并创建类。连接,执行命令,查看可用的镜像执行命令,使用镜像启动容器。至此,使用插件构建镜像并运行容器完成,访问路径,获得结果
1.登录网站https://start.spring.io/,生成一个基本的SpringBoot应用。
2.将应用导入Eclipse IDE并创建Application类。目录结构如下:
Application代码如下:
package com.example.demo.controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class Application { @RequestMapping(value="/phone") public String index(){ return "Hello World!"; } }
3.在pom.xml文件中增加插件配置:
com.spotify docker-maven-plugin 0.4.12 microservice-eureka-demo java ["java", "-jar", "/${project.build.finalName}.jar"] / ${project.build.directory} ${project.build.finalName}.jar
4.pom.xml文件中增加依赖:
org.springframework.boot spring-boot-starter-web
5.配置本地环境变量,设置docker文件构建主机(主机192.168.244.130已经安装完docker环境)
root@ubuntu-02:~# docker -v Docker version 17.05.0-ce, build 89658be
本地环境变量配置如下:
6.进入代码目录,执行命令“mvn clean package docker:build”项目编译成功。
[INFO] [INFO] --- maven-jar-plugin:2.6:jar (default-jar) @ dockerdemo --- [INFO] Building jar: C:UsersSeanDownloadsdemodemo argetdockerdemo-0.0.1-SNAPSHOT.jar [INFO] [INFO] --- spring-boot-maven-plugin:1.5.4.RELEASE:repackage (default) @ dockerdemo --- [INFO] [INFO] --- docker-maven-plugin:0.4.12:build (default-cli) @ dockerdemo --- [INFO] Copying C:UsersSeanDownloadsdemodemo argetdockerdemo-0.0.1-SNAPSHOT.jar -> C:UsersSeanDownloadsdemodemo argetdockerdockerdemo-0.0.1-SNAPSHOT.jar [INFO] Building image microservice-eureka-demo Step 1/3 : FROM java ---> d23bdf5b1b1b Step 2/3 : ADD /dockerdemo-0.0.1-SNAPSHOT.jar // ---> e1b3c3de711c Removing intermediate container a9e57b1d9883 Step 3/3 : ENTRYPOINT java -jar /dockerdemo-0.0.1-SNAPSHOT.jar ---> Running in 7a3cdc1d112b ---> 1f800bf8cb24 Removing intermediate container 7a3cdc1d112b Successfully built 1f800bf8cb24 Successfully tagged microservice-eureka-demo:latest [INFO] Built microservice-eureka-demo [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 39.982 s [INFO] Finished at: 2017-07-23T21:51:21+08:00 [INFO] Final Memory: 42M/393M [INFO] ------------------------------------------------------------------------
7.ssh连接192.168.244.130,执行命令“docker images”,查看可用的镜像:
root@ubuntu-02:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE microservice-eureka-demo latest 1f800bf8cb24 23 minutes ago 658MB
8.执行命令“docker run -p 8080:8080 microservice-eureka-demo:latest”,使用镜像microservice-eureka-demo:latest启动docker容器。
root@ubuntu-02:~# docker run -p 8080:8080 microservice-eureka-demo:latest . ____ _ __ _ _ / / ___"_ __ _ _(_)_ __ __ _ ( ( )\___ | "_ | "_| | "_ / _` | / ___)| |_)| | | | | || (_| | ) ) ) ) " |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v1.5.4.RELEASE) 2017-07-23 14:19:21.766 INFO 1 --- [ main] com.example.demo.DemoApplication : Starting DemoApplication v0.0.1-SNAPSHOT on 656842f890d3 with PID 1 (/dockerdemo-0.0.1-SNAPSHOT.jar started by root in /) 2017-07-23 14:19:21.792 INFO 1 --- [ main] com.example.demo.DemoApplication : No active profile set, falling back to default profiles: default 2017-07-23 14:19:22.402 INFO 1 --- [ main] ationConfigEmbeddedWebApplicationContext : Refreshing org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@5a2e4553: startup date [Sun Jul 23 14:19:22 UTC 2017]; root of context hierarchy 2017-07-23 14:19:31.950 INFO 1 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat initialized with port(s): 8080 (http) 2017-07-23 14:19:32.015 INFO 1 --- [ main] o.apache.catalina.core.StandardService : Starting service [Tomcat] 2017-07-23 14:19:32.032 INFO 1 --- [ main] org.apache.catalina.core.StandardEngine : Starting Servlet Engine: Apache Tomcat/8.5.15 2017-07-23 14:19:32.467 INFO 1 --- [ost-startStop-1] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring embedded WebApplicationContext 2017-07-23 14:19:32.467 INFO 1 --- [ost-startStop-1] o.s.web.context.ContextLoader : Root WebApplicationContext: initialization completed in 10082 ms 2017-07-23 14:19:33.101 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.ServletRegistrationBean : Mapping servlet: "dispatcherServlet" to [/] 2017-07-23 14:19:33.141 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: "characterEncodingFilter" to: [/*] 2017-07-23 14:19:33.148 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: "hiddenHttpMethodFilter" to: [/*] 2017-07-23 14:19:33.161 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: "httpPutFormContentFilter" to: [/*] 2017-07-23 14:19:33.161 INFO 1 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: "requestContextFilter" to: [/*] 2017-07-23 14:19:34.708 INFO 1 --- [ main] s.w.s.m.m.a.RequestMappingHandlerAdapter : Looking for @ControllerAdvice: org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@5a2e4553: startup date [Sun Jul 23 14:19:22 UTC 2017]; root of context hierarchy 2017-07-23 14:19:35.105 INFO 1 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/phone]}" onto public java.lang.String com.example.demo.controller.Application.index() 2017-07-23 14:19:35.127 INFO 1 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error],produces=[text/html]}" onto public org.springframework.web.servlet.ModelAndView org.springframework.boot.autoconfigure.web.BasicErrorController.errorHtml(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) 2017-07-23 14:19:35.138 INFO 1 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error]}" onto public org.springframework.http.ResponseEntity> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest) 2017-07-23 14:19:35.277 INFO 1 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/webjars/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] 2017-07-23 14:19:35.285 INFO 1 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] 2017-07-23 14:19:35.466 INFO 1 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/**/favicon.ico] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] 2017-07-23 14:19:36.180 INFO 1 --- [ main] o.s.j.e.a.AnnotationMBeanExporter : Registering beans for JMX exposure on startup 2017-07-23 14:19:36.449 INFO 1 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 8080 (http) 2017-07-23 14:19:36.477 INFO 1 --- [ main] com.example.demo.DemoApplication : Started DemoApplication in 17.363 seconds (JVM running for 19.474)
9.执行命令“docker ps”,查看启动的docker容器。
root@ubuntu-02:~# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 08099bd4b8e1 microservice-eureka-demo:latest "java -jar /docker..." 27 seconds ago Up 26 seconds 0.0.0.0:8080->8080/tcp upbeat_borg
10.执行命令“docker exec -it 08099bd4b8e1 bin/bash”,进入docker容器。
root@ubuntu-02:~# docker exec -it 08099bd4b8e1 bin/bash root@08099bd4b8e1:/#
11.执行命令“ps -ef”,可用查看到docker容器里面启动的进程,即是pom.xml配置文件中配置的插件docker-maven-plugin的entryPoint,java -jar /dockerdemo-0.0.1-SNAPSHOT.jar。
["java", "-jar", "/${project.build.finalName}.jar"] root@08099bd4b8e1:/# ps -ef UID PID PPID C STIME TTY TIME CMD root 1 0 4 14:20 ? 00:00:17 java -jar /dockerdemo-0.0.1-SNAPSHOT.jar root 34 0 0 14:24 ? 00:00:00 bin/bash root 41 34 0 14:26 ? 00:00:00 ps -ef root@08099bd4b8e1:/#
12.至此,使用docker插件构建docker镜像并运行docker容器完成,访问路径“http://192.168.244.130:8080/p...”,获得controller结果:

摘要:什么是可以简单地理解为可以代替你实现自动从拉取代码,打包,部署到远程服务器的工具。随后登录后发现页面空白,没找到具体原因,重启下容器后再登录就好了。主要是配置访问服务器拉取代码,还有配置远程服务器地址,目的是为了打包后上传文件到远程服务器。 showImg(https://segmentfault.com/img/remote/1460000017907307?w=495&h=300)...
