#把宿主机当前上下文的c.txt拷贝到/usr/local路径下

COPY c.txt /usr/local/cincontainer.txt

#把java和tomocat添加到容器中

ADD jdk-8u152-linux-x64.tar.gz /usr/local/

ADD apache-tomcat-9.0.20.tar.gz /usr/local/

#安装vim编辑器

RUN yum -y install vim

#设置登录时候workdir路径

ENV MYPATH /usr/local/

WORKDIR $MYPATH

#配置java和tomcat环境变量

ENV JAVA_HOME /usr/local/jdk1.8.0_152

ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.20

ENV CATALINA_BASE /usr/local/apache-tomcat-9.0.20

ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin

#容器运行时监听的端口

EXPOSE 8080

#启动时运行tomcat

CMD /usr/local/apache-tomcat-9.0.20/bin/startup.sh && tail -f /usr/local/apache-tomcat-9.0.20/logs/catalina.out

 

构建生成镜像

docker build -t irishtomcat9 .

通过镜像启动容器

docker run -d -p 9999:8080 --name mytomcat9 -v /usr/local/mytomcat9/test:/usr/local/apache-tomcat-9.0.20/webapps/test -v /usr/local/mytomcat9/tomcat9logs://usr/local/apache-tomcat-9.0.20/logs irishtomcat9

可以将web工程拷贝到/usr/local/mytomcat9/test目录下，再重新启动容器，就可以访问web工程了
