基于centos7创建tomcat镜像_from centos:7-CSDN博客

本文链接：https://blog.csdn.net/baidu_38432732/article/details/117283399

本文档展示了如何使用Dockerfile从CentOS基础镜像构建包含Java和Tomcat的自定义镜像，并将其推送到harbor-test.sgpexchange.com仓库。详细步骤包括解压JDK和Tomcat包，设置环境变量，暴露8080端口以及通过ENTRYPOINT指令启动Tomcat服务。

编写Dockerfile

FROM centos:7
MAINTAINER This is Tomcat
#解压jdk包
ADD jdk1.8.0_231.tar.gz /usr/local/
#进入工作目录
WORKDIR /usr/local/
#重命名
RUN mv jdk1.8.0_231 java
#设置环境变量
ENV JAVA_HOME /usr/local/java
ENV JRE_HOME /usr/local/java/jre
ENV CLASSPATH /usr/local/java/lib:/usr/local/java/jre/lib
ENV PATH /usr/local/java/bin:$PATH
#解压tomcat包
ADD tomcat-mod.tar.gz /usr/local/
#进入工作目录
WORKDIR /usr/local/
#重命名
RUN mv tomcat-mod /usr/local/tomcat
#暴露端口
EXPOSE 8080
#启动tomcat
ENTRYPOINT ["/usr/local/tomcat/bin/catalina.sh","run"]
