dockerfile簡單練手，創建基於jdk1.7的tomcat7

使用的基礎鏡像

FROM ubuntu

創建目錄

RUN mkdir -p /docker_home/local

把當前目錄下的jdk文件夾添加到鏡像

ADD tomcat7 /docker_home/local/tomcat7
ADD java17 /docker_home/local/java17
ENV JAVA_HOME /docker_home/local/java17/
ENV CATALINA_HOME /docker_home/local/tomcat7
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin

暴露8080端口

EXPOSE 8080

啓動時運行tomcat

CMD ["/docker_home/local/tomcat7/bin/catalina.sh",“run”]
