使用docker Maven插件本地構建docker鏡像并發布到遠程服務器

jcc / 3297人閱讀

摘要：登錄網站，生成一個基本的應用。將應用導入并創建類。連接，執行命令，查看可用的鏡像執行命令，使用鏡像啟動容器。至此，使用插件構建鏡像并運行容器完成，訪問路徑，獲得結果

1.登錄網站https://start.spring.io/，生成一個基本的SpringBoot應用。

2.將應用導入Eclipse IDE并創建Application類。目錄結構如下：

Application代碼如下：

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文件中增加依賴：

          
            org.springframework.boot  
            spring-boot-starter-web

5.配置本地環境變量，設置docker文件構建主機（主機192.168.244.130已經安裝完docker環境）

root@ubuntu-02:~# docker -v
Docker version 17.05.0-ce, build 89658be

本地環境變量配置如下：

6.進入代碼目錄，執行命令“mvn clean package docker:build”項目編譯成功。

7.ssh連接192.168.244.130，執行命令“docker images”，查看可用的鏡像：

root@ubuntu-02:~# docker images
REPOSITORY                                                           TAG                 IMAGE ID            CREATED             SIZE
microservice-eureka-demo                                             latest              1f800bf8cb24        23 minutes ago      658MB

8.執行命令“docker run -p 8080:8080 microservice-eureka-demo:latest”，使用鏡像microservice-eureka-demo:latest啟動docker容器。

root@ubuntu-02:~# docker run -p 8080:8080 microservice-eureka-demo:latest

9.執行命令“docker ps”，查看啟動的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.執行命令“docker exec -it 08099bd4b8e1 bin/bash”，進入docker容器。

root@ubuntu-02:~# docker exec -it 08099bd4b8e1 bin/bash 
root@08099bd4b8e1:/#

11.執行命令“ps -ef”，可用查看到docker容器里面啟動的進程，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:/#
