jenkins docker 发布

分享下怎么使用jenkins 发布 docker

首先准备docker的相关部分

docker tomcat基础镜像，这边使用centos7做系统，dockerfile如下：

#tomcat基础镜像
#我这边先把tomcat 各项配置好了，然后重新打包，传入docker，tomcat的数据目录设置在 /data/www 下  ，机器上先装了JDK

FROM centos:

MAINTAINER www.cnblogs.com/fanpiao

ENV VERSION=8.5.

ENV JAVA_HOME /usr/local/jdk

WORKDIR /usr/local/

ADD apache-tomcat-${VERSION}.tar.gz .

RUN mv apache-tomcat-${VERSION} tomcat && \

    rm -rf apache-tomcat-${VERSION}.tar.gz && \

    yum install -y unzip && \

    mkdir -p /data/www

#ENV PATH $PATH:/usr/local/tomcat/bin

#WORKDIR /usr/local/tomcat

#EXPOSE

#CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]

打包成镜像，并上传到容器仓库

docker build -t registry.cn-beij.aliyuncs.com/basis/tomcat:v7 .

#可以和我一样使用阿里云提供的容器镜像服务，免费的

docker push registry.cn-beij.aliyuncs.com/basis/tomcat:v7

上传完成后备用

#jenkins pipeline 脚本准备

ansbile-playbook准备,ansbile ,host主机的配置请自己先配置

jenkisn 的配置，需要如下设置如下参数

在流水线这里配置上刚才准备的 jenkins pipeline 脚本

保存后就完成了，效果如下
