jenkins.war

3、编写Dockerfile

# This my first jenkins Dockerfile
# Version 1.0
FROM centos:7
MAINTAINER ligaojie@123.com
ENV JAVA_HOME /usr/local/jdk-11.0.16
ENV TOMCAT_HOME /usr/local/apache-tomcat-9.0.79
ENV PATH=$JAVA_HOME/bin:$PATH
ADD apache-tomcat-9.0.79.tar.gz /usr/local/

RUN rm -rf /usr/local/apache-tomcat-9.0.79/webapps/*
ADD jenkins.war /usr/local/apache-tomcat-9.0.79/webapps
RUN rm -rf apache-tomcat-9.0.79.tar.gz jdk-11.0.16_linux-x64_bin.tar.gz
RUN yum install fontconfig -y

ENTRYPOINT ["/usr/local/apache-tomcat-9.0.79/bin/catalina.sh","run"]

docker build -t jenkins:v1 .

5、docker images(查看所有镜像)，Jenkins:v1构建成功

-d(后台运行)    --name(自定义名称)   -p(端口映射)

docker run -itd --name jenkins1 -p 8081:8080  jenkins:v1
