##安裝jdk
RUN mkdir /usr/soft
#RUN mkdir /usr/local/jdk
#COPY jdk-8u241-linux-x64.tar.gz /usr/soft/jdk-8u241-linux-x64.tar.gz
#RUN tar xvf /usr/soft/jdk-8u241-linux-x64.tar.gz -C /usr/local/jdk
#RUN rm -rf /usr/soft/jdk-8u241-linux-x64.tar.gz

##安裝tomcat
RUN mkdir -p /usr/local/tomcat
COPY apache-tomcat-7.0.100.tar.gz /usr/soft/apache-tomcat-7.0.100.tar.gz
RUN tar xvf /usr/soft/apache-tomcat-7.0.100.tar.gz -C /usr/local/tomcat
RUN rm -rf /usr/soft/apache-tomcat-7.0.100.tar.gz

##設置環境變量
#ENV JAVA_HOME /usr/local/jdk/jdk1.8.0_241
ENV CATALINA_HOME /usr/local/tomcat/apache-tomcat-7.0.100
#ENV PATH $PATH:$JAVA_HOME/bin:$CATCHA_HOME/bin
ENV PATH $PATH:$CATCHA_HOME/bin

##打包項目拷貝到tomcat webapps目錄中
##COPY xxx /usr/local/tomcat/apache-tomcat-7.0.100/webapps

  COPY wthfree/wf.tar /usr/local/tomcat/apache-tomcat-7.0.103/webapps/
  RUN tar -xvf /usr/local/tomcat/apache-tomcat-7.0.103/webapps/wf.tar -C /usr/local/tomcat/apache-tomcat-7.0.103/webapps
  RUN rm -rf /usr/local/tomcat/apache-tomcat-7.0.103/webapps/wf.tar

##內部開啟服務端口
EXPOSE 8080

##最后啟動sshd進程，防止容器啟動后就不見了
##CMD /usr/sbin/sshd -D
CMD ["./usr/local/tomcat/apache-tomcat-7.0.100/bin/catalina.sh", "run"]

 build：docker build --rm=true --no-cache=false -t java8tomcat7:1.0 .

運行：docker run -it -d --name tomcat7  -p 8099:8080  java8tomcat7

掛載目錄運行：docker run -it -d --name tomcat8 -p 8089:8080 -v /root/tomcat/webapps:/usr/local/tomcat/webapps tomcat
