Jenkins构建Docker镜像并推送至Harbor仓库的实现

目录Dockerfile文件pom.xmlJenkins配置

​ spring boot项目通过Jenkins集成构建Docker镜像推送到harbor仓库并启动容器然后拉取镜像到本地运行容器

Dockerfile文件

位置：存在根目录下，与src同级

FROM java:8 # 作者 MAINTAINER zhaoyc VOLUME /tmp #ARG JAR_FILE #将jar包添加到容器中并更名为app.jar ADD target/*.jar app.jar RUN bash -c touch /app.jar ENV TZ=Asia/Shanghai #RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone EXPOSE 81 #CMD [“-jar”, “/app.jar”] “nohup” “&” ENTRYPOINT [“java”,”-Djava.security.egd=file:/dev/./urandom”,”-jar”,”/app.jar”]

pom.xml

要指定maven版本号为1.4.2,其他版本未测试，否则找不到main-class

<plugins> <!– mavn jar包启动插件–> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>1.4.2.RELEASE</version> </plugin> </plugins>

Jenkins配置

系统设置配置docker–需要安装Docker plugin

新建maven项目 配置参数构建

项目git仓库配置

mvn构建 buile配置

构建docke镜像推送至仓库配置

推送到仓库后执行脚本
