利用Dockerfile文件和docker 命令 生成docker鏡像

 

一、sprinboot部分

1、springboottest 的springboot項目，寫了controller測試

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.Date;

/*
 *
 *@Description TODO
 *@Author chenzhian
 *@Date 2022/9/21 16:55
 */
@RestController()
public class indexController {


    @Value("${spring.profiles.active:dev}")
    private String active;

    @Value("${smx:dev}")
    private String smx;

    @RequestMapping(method = RequestMethod.GET,value = "/getdate")
    public String getdate() {
        return "active is "+active+" ,"+ new Date().toString();
    }
}

2、SpringBootApplication啓動類要註釋不檢查數據庫

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.List;

/*
 *
 *@Description 啓動類
 *@Author chenzhian
 *@Date 2021/11/11 17:36
 */
@SpringBootApplication(scanBasePackages = {"com.zhianchen.mysqlremark.springboottest"},exclude = DataSourceAutoConfiguration.class)  //
@Slf4j
public class SpringbootTestApplication  {
    public static void main(String[] args) {
        SpringApplication.run(SpringbootTestApplication.class,args);
    }

}

 

3、pom.xml

4、application.yml

server:
  port: 9021
spring:
  application:
    name: com-zhianchen-mysqlremark-springboottest

5、maven 打包成jar

二、docker

1、Docker文件內容

FROM docker.io/ascdc/jdk8
MAINTAINER docker_maven [email protected]
WORKDIR /ROOT
ADD com-zhianchen-mysqlremark-springboottest.jar /ROOT/
["java", "-jar", "-Xms128m", "-Xmx256m", "-XX:+PrintGCDetails", "-XX:+PrintGCTimeStamps", "-XX:+PrintGCTimeStamps", "-XX:+HeapDumpOnOutOfMemoryError", "-XX:HeapDumpPath=/opt/infosec/cssp","-Dspring.profiles.active=test", "com-zhianchen-mysqlremark-springboottest.jar"]
CMD ["java", "-version"]

 

然後把Dockerfile文件和 jar都放在同一個目錄，執行

 

docker build -f dockerfile文件路徑 -t 鏡像名稱:版本號 .

例如 docker build -f Dockerfile -t springboottest2:1.0.0 .

 

docker images 查看鏡像

 

執行啓動，因爲我這裏指定了版本，所以啓動的時候要指定版本，不然會去遠程拉last

]# docker run -d -m 512m -p 9022:9021 springboottest2:1.0.0 

因爲是我上面寫了-d，進行異步執行，所以要看下查看是否運行成功

]# docker ps
