Docker+jenkins自动化部署 （公司）

Posted on Edited on In

公司的部署方式

复制公司的部署脚本和流程等。

  1. 配置gitlab或者直接使用github
  2. 配置docker和jenkins
  3. 配置一个maven项目到github或者gitlab，稍后执行maven打包命令
  4. 配置一个jenkins的maven工程，可以看之前写的jenkin的日志
  5. 假设部署的包放在/root/edu-deploy下
  6. /root/edu-deploy目录下应该有执行docker打包脚本和一个Dockerfile模板，所有的自动生成的目录都从这个模板拷贝
  7. /root/edu-deploy/build_image.sh内容

  1. 模板Dockerfile文件 /root/edu-deploy/Dockerfile

From centos
From openjdk:8-jdk
VOLUME /tmp
ADD *.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
#ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
CMD exec java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar


  1. 之后只要在jenkins中点击立即构建，应该会自动打包一个docker镜像在/root/edu-deploy下
