Docker自定义一个Tomcat镜像
本文是基于CentOS 7.3系统环境，进行Docker的学习和使用
- CentOS 7.3
- Docker-ce
一、自定义一个Tomcat镜像
(1) 创建一个目录
mkdir -p /data/mydockerfile/tomcat9
(2) 下载Tomcat9和jdk
apache-tomcat-9.0.30.tar.gz
jdk-8u201-linux-x64.tar.gz
cp /root/apache-tomcat-9.0.30.tar.gz /data/mydockerfile/tomcat9
cp /root/jdk-8u201-linux-x64.tar.gz /data/mydockerfile/tomcat9
(3) 编写Dockerfile
FROM centos
MAINTAINER xuzheng<[email protected]>
COPY readme.txt /usr/local/README.txt
ADD jdk-8u201-linux-x64.tar.gz /usr/local
ADD apache-tomcat-9.0.30.tar.gz /usr/local
RUN yum -y install vim
ENV MYPATH /usr/local
WORKDIR MYPATH
ENV JAVA_HOME /usr/local/jdk1.8.0_201
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.30
ENV CATALINA_BASE /usr/local/apache-tomcat-9.0.30
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
EXPOSE 8080
CMD /usr/local/apache-tomcat-9.0.30/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.30/bin/logs/catalina.out
(4) 构建镜像
docker build -t xztomcat9 .
