Dockerfile构建Springboot镜像 简介实例演示 前期准备 Docker环境Springboot项目Dockerfile文件 Windows 要求构建镜像启动测试 Linux 要求构建镜像启动测试
简介 容器技术大流行的时代也是docker大流行的时代。 此文章以一个简单的实例为基础帮助大家学习和了解如何使用Dockerfile指令构建一个Springboot的Java项目镜像。 提示实例非常简单旨在帮助大家了解基础知识本文的知识在实际工作中肯定是不够用的还需要自行根据实际情况去学习感谢您的阅读。
实例演示
具体操作介绍了Windows和Linux两种方式。
前期准备
Docker环境 Windows请安装Docker Desktophttps://docs.docker.com/desktop/install/windows-install/ Linux请安装Dockerhttps://docs.docker.com/desktop/install/linux-install/
Springboot项目 源码learn/java/docker-springboot at main · DingDangDog/learn (github.com) Jar包下载地址docker-springboot-1.0.jar.zip Controller代码示例
package io.github.dingdangdog.controller;
import io.github.dingdangdog.utils.FileUtilOm;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/*** say hello** author DingDangDog* since 2022/10/4 11:13*/
RestController
RequestMapping(/say)
public class SayController {GetMapping(/hello)public String hello(String name) {System.out.println(name);// 保存文件FileUtilOm.saveFile(/tmp/, name, name);return Hello name !;}
}
Dockerfile文件
文件名必须为Dockerfile无拓展名请放在jar包同级目录下。
# 基础镜像
FROM openjdk:8-jdk
# 作者声明原为MAINTAINER变更为LABEL
# MAINTAINER DingDangDog
LABEL authorDingDangDog
# 容器卷设置
VOLUME /tmp
# 向基础镜像内添加文件并重命名为docker_boot.jar
add docker-springboot-1.0.jar docker_boot.jar
# 执行前置脚本。据说是修改文件时间不太明白具体作用望有大佬指点迷津
RUN bash -c touch /docker_boot.jar
# 最终执行脚本
ENTRYPOINT [java, -jar, /docker_boot.jar]
# 暴露端口
EXPOSE 10240
指令解析请参考文章Dockerfile基础一文通
Windows
要求 前期准备 Windows可以正常启动Docker服务 如下图运行状态绿色为正在运行 [外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-kYndCTFA-1670767109761)(https://github.com/DingDangDog/ddd-document/blob/main/docker/images/image-20221004122548749.png?rawtrue)] 构建镜像 在jar包所在文件夹下打开cmd命令行窗口运行构建命令 docker build -t docker_boot:1.0 . 命令解析 docker build构建镜像-t docker_boot:1.0 -t--tag指定镜像名称为docker_boot版本为1.0. 指定Dockerfile文件在当前文件夹下 构建成功日志如下 [] Building 76.3s (9/9) FINISHED [internal] load build definition from Dockerfile 0.0s transferring dockerfile: 254B 0.0s [internal] load .dockerignore 0.0s transferring context: 2B 0.0s [internal] load metadata for docker.io/library/openjdk:8-jdk 4.6s [auth] library/openjdk:pull token for registry-1.docker.io 0.0s [internal] load build context 0.1s transferring context: 19.65MB 0.1s [1/3] FROM docker.io/library/openjdk:8-jdksha256:86e863cc57215cfb181bd319736d0baf625fe8f150577f9eb58bd937f5 70.8s resolve docker.io/library/openjdk:8-jdksha256:86e863cc57215cfb181bd319736d0baf625fe8f150577f9eb58bd937f54 0.0s sha256:86e863cc57215cfb181bd319736d0baf625fe8f150577f9eb58bd937f5452cb8 1.04kB / 1.04kB 0.0s sha256:3af2ac94130765b73fc8f1b42ffc04f77996ed8210c297fcfa28ca880ff0a217 1.79kB / 1.79kB 0.0s sha256:001c52e26ad57e3b25b439ee0052f6692e5c0f2d5d982a00a8819ace5e521452 55.00MB / 55.00MB 24.0s sha256:2068746827ec1b043b571e4788693eab7e9b2a95301176512791f8c317a2816a 10.88MB / 10.88MB 13.1s sha256:b273004037cc3af245d8e08cfbfa672b93ee7dcb289736c82d0b58936fb71702 7.81kB / 7.81kB 0.0s sha256:d9d4b9b6e964657da49910b495173d6c4f0d9bc47b3b44273cf82fd32723d165 5.16MB / 5.16MB 18.0s sha256:9daef329d35093868ef75ac8b7c6eb407fa53abbcb3a264c218c2ec7bca716e6 54.58MB / 54.58MB 43.2s sha256:d85151f15b6683b98f21c3827ac545188b1849efb14a1049710ebc4692de3dd5 5.42MB / 5.42MB 25.5s sha256:52a8c426d30b691c4f7e8c4b438901ddeb82ff80d4540d5bbd49986376d85cc9 210B / 210B 25.3s extracting sha256:001c52e26ad57e3b25b439ee0052f6692e5c0f2d5d982a00a8819ace5e521452 1.9s sha256:8754a66e005039a091c5ad0319f055be393c7123717b1f6fee8647c338ff3ceb 105.92MB / 105.92MB 68.4s extracting sha256:d9d4b9b6e964657da49910b495173d6c4f0d9bc47b3b44273cf82fd32723d165 0.2s extracting sha256:2068746827ec1b043b571e4788693eab7e9b2a95301176512791f8c317a2816a 0.2s extracting sha256:9daef329d35093868ef75ac8b7c6eb407fa53abbcb3a264c218c2ec7bca716e6 2.1s extracting sha256:d85151f15b6683b98f21c3827ac545188b1849efb14a1049710ebc4692de3dd5 0.2s extracting sha256:52a8c426d30b691c4f7e8c4b438901ddeb82ff80d4540d5bbd49986376d85cc9 0.0s extracting sha256:8754a66e005039a091c5ad0319f055be393c7123717b1f6fee8647c338ff3ceb 2.1s [2/3] ADD docker-springboot-1.0.jar docker_boot.jar 0.3s [3/3] RUN bash -c touch /docker_boot.jar 0.4s exporting to image 0.1s exporting layers 0.1s writing image sha256:0fcc9c262e90d6a05213ec432924e6835647d233a64ad0747cf7dd406a2a40bd 0.0s naming to docker.io/library/docker_boot:1.0 0.0sUse docker scan to run Snyk tests against images to find vulnerabilities and learn how to fix them 查看镜像
