一、实验环境：
[root@docker1 tomcat9]# cat /etc/redhat-release CentOS Linux release 7.7.1908 (Core) [root@docker1 tomcat9]# uname -r 3.10.0-1062.el7.x86_64
二、实验准备：
没有资源的可以上我的网盘下载：pan.baidu.com/s/1r3Y2ziVV…提取码：eg0dapache-tomcat-8.0.9.tar.gz jdk-8u161-linux-x64.tar.gz
[root@docker1 tomcat9]# pwd /mydockerfile/tomcat9 [root@docker1 tomcat9]# ll total 194244 -rw-r--r--. 1 root root 9144234 May 21 03:08 apache-tomcat-8.0.9.tar.gz -rw-r--r--. 1 root root 0 May 21 02:56 c.txt -rw-r--r--. 1 root root 189756259 May 21 03:08 jdk-8u161-linux-x64.tar.gz [root@docker1 tomcat9]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE centos latest 470671670cac 4 months ago 237MB
三、创建Dockerfile*(重点)
[root@docker1 tomcat9]# vim dockerfile FROM centos MAINTAINER caq(mildcaq@163.com) # 把宿主机当前目录下c.txt拷贝到容器/usr/local/路径下 COPY c.txt /usr/local/newname.txt # 把java与tomcat加入到容器 ADD jdk-8u161-linux-x64.tar.gz /usr/local/ ADD apache-tomcat-8.0.9.tar.gz /usr/local/ #安装vim编辑器 RUN yum install -y vim #设置工作访问路径 ENV MYPATH /usr/local WORKDIR $MYPATH #设置JAVA与tomcat环境变量 ENV JAVA_HOME /usr/local/jdk1.8.0.161 ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.har ENV CATALINA_HOME /usr/local/apache-tomcat-8.0.9 ENV CATALINA_BASE /usr/local/apache-tomcat-8.0.9 ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin # 容器运行时的监听端口 EXPOSE 8080 # 启动时运行tomcat CMD /usr/local/apache-tomcat-8.0.9/bin/startup.sh && tail -F /usr/local/apache-tomcat-8.0.9/bin/logs/catalina.out [root@docker1 tomcat9]# ll total 194248 -rw-r--r--. 1 root root 9144234 May 21 03:08 apache-tomcat-8.0.9.tar.gz -rw-r--r--. 1 root root 0 May 21 02:56 c.txt -rw-r--r--. 1 root root 862 May 21 03:31 dockerfile -rw-r--r--. 1 root root 189756259 May 21 03:08 jdk-8u161-linux-x64.tar.gz
四、创建容器
[root@docker1 tomcat9]# docker build -t testtomcat .

五、运行容器
[root@docker1 tomcat9]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [root@docker1 tomcat9]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE testtomcat latest d57ca588cc1b 5 minutes ago 694MB [root@docker1 tomcat9]# docker run -d -p 80:8080 -v /mydockerfile/tomcat9/test:/usr/local/apache-tomcat-8.0.9/webapps/test -v /mydockerfile/tomcat9/test2/:/usr/local/apache-tomcat-8.0.9/logs --privileged=true testtomcat 43a5d886018d016984ea35941b92d08c72576c3c1ad44f9d9986393884a6dc06
六、进行测试
[root@docker1 tomcat9]# ll total 194248 -rw-r--r--. 1 root root 9144234 May 21 03:08 apache-tomcat-8.0.9.tar.gz -rw-r--r--. 1 root root 0 May 21 02:56 c.txt -rw-r--r--. 1 root root 862 May 21 03:31 dockerfile -rw-r--r--. 1 root root 189756259 May 21 03:08 jdk-8u161-linux-x64.tar.gz drwxr-xr-x. 2 root root 6 May 21 03:42 test drwxr-xr-x. 2 root root 26 May 21 03:42 test2 [root@docker1 tomcat9]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 43a5d886018d testtomcat "/bin/sh -c '/usr/lo…" 3 minutes ago Up 3 minutes 0.0.0.0:80->8080/tcp gallant_swartz [root@docker1 tomcat9]# docker exec 43a5d886018d ls -l total 0 drwxr-xr-x. 1 root root 21 May 21 07:32 apache-tomcat-8.0.9 drwxr-xr-x. 2 root root 6 May 11 2019 bin drwxr-xr-x. 2 root root 6 May 11 2019 etc drwxr-xr-x. 2 root root 6 May 11 2019 games drwxr-xr-x. 2 root root 6 May 11 2019 include drwxr-xr-x. 8 10 143 255 Dec 20 2017 jdk1.8.0_161 drwxr-xr-x. 2 root root 6 May 11 2019 lib drwxr-xr-x. 2 root root 6 May 11 2019 lib64 drwxr-xr-x. 2 root root 6 May 11 2019 libexec -rw-r--r--. 1 root root 0 May 21 06:56 newname.txt drwxr-xr-x. 2 root root 6 May 11 2019 sbin drwxr-xr-x. 5 root root 49 Jan 13 21:49 share drwxr-xr-x. 2 root root 6 May 11 2019 src
