ADD/COPY案例

ADD/COPY案例--自定义镜像tomcat9

1.mkdir -p /root/mydocker/tomcat9

2.touch 1.txt

3.将jdk和tomcat安装包拷贝到目录下

4.创建Dockerfile文件

FROM centos
MAINTAINER yz<yz@126.com>
#宿主机的1.txt文件拷贝到容器/usr/local下
COPY 1.txt /usr/local/cincontainer.txt
#jdk/tomcat
ADD jdk-8u261-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-8.5.55.tar.gz /usr/local/
#INSTALL vim
RUN yum install -y vim
#设置WORKDIR
ENV MYDIR /usr/local
WORKDIR $MYDIR
#PATH
ENV JAVA_HOME /usr/local/jdk1.8.0_261
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.55
ENV CATALINA_BASE /usr/local/apache-tomcat-8.5.55
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
#port
EXPOSE 8080
#running tamcat
CMD /usr/local/apache-tomcat-8.5.55/bin/startup.sh && tail -F /usr/local/apache-tomcat-8.5.55/bin/logs/catalina.out

5.构建镜像

docker build -f Dockerfile -t mytomcat9 .

6.运行容器

docker run -d -p 9090:8080 --name mytomcat9 -v /root/mydocker/tomcat9/test:/usr/local/apache-tomcat-8.5.55/webapps/test -v /root/mydocker/tomcat9/logs:/usr/local/apache-tomcat-8.5.55/logs --privileged=true mytomcat9

7.验证

[root@aaa ~/mydocker/tomcat9]# docker ps
