Jenkins官方镜像，初始化后无法安装插件问题

建议使用Jenkins中文社区提供的jenkins镜像

jenkins的中文社区官网：https://www.jenkins.io/zh

镜像拉取地址

docker pull jenkinszh/jenkins-zh:2.267

设置挂载jenkins目录

mkdir /home/jenkins_home
chmod -R 777  /home/jenkins_home

启动容器

docker run -d -p 8080:8080 -p 50000:50000 --name jenkins-zh -v /home/jenkins_home:/var/jenkins_home jenkinszh/jenkins-zh:2.267

第二种方法：建议使用tomcat进行自定义构建镜像

1. 选择基础镜像 ccr.ccs.tencentyun.com/wego-prod/tomcat9-jdk8:v2.0

2. 删除里面多与的内容

   docker run -itd --name tomcat-test ccr.ccs.tencentyun.com/wego-prod/tomcat9-jdk8:v2.0
   docker exec -it tomcat-test bash
   删除多余的内容，如日记等信息
   

3. 构建底层基础镜像

   docker commit -a "wanglinhao" -m "这是一个没有日志的tomcat镜像" 83eaf978cdb6 ccr.ccs.tencentyun.com/wego-prod/tomcat9-jdk8:wanglinhao
   docker push ccr.ccs.tencentyun.com/wego-prod/tomcat9-jdk8:wanglinhao
   

4. 编写dockerfile

   FROM ccr.ccs.tencentyun.com/wego-prod/tomcat9-jdk8:wanglinhao
   COPY ./jenkins-2.333.war /usr/local/tomcat/webapps/ROOT.war
   
   #ENV JAVA_HOME /var/jdk1.8.0_121
   #ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin
   ENV JENKINS_HOME /var/jenkins_home
   
   # 安装git
   RUN echo > /etc/apt/sources.list \
   && echo "deb http://mirrors.163.com/debian stretch main" >> /etc/apt/sources.list \
   && echo "deb http://mirrors.163.com/debian stretch-updates main" >> /etc/apt/sources.list \
   && apt-get update \
   && apt-get install git-all -y
   
   CMD ["/usr/local/tomcat/bin/run.sh"]
   
   
   

5. 构建镜像，下载war包

   docker build -t ccr.ccs.tencentyun.com/wego/jenkins:zh-2.333 .
   docker push ccr.ccs.tencentyun.com/wego/jenkins:zh-2.333
   

6. 最后启动

7. 通过war包启动的日志，初始密码位置

   cat /root/.jenkins/secrets/initialAdminPassword
