创建工作目录

[root@localhost ~]# mkdir tomcat
[root@localhost ~]# cd tomcat/

编写配置文件

[root@localhost tomcat]# cat Dockerfile
#基于的基础镜像

构建镜像

[root@localhost tomcat]# docker build -t apache:new .

[root@localhost tomcat]# docker images apache:new
REPOSITORY TAG IMAGE ID CREATED SIZE
apache new 79d3192369be 25 seconds ago 1.19 GB

测试容器

[root@localhost tomcat]# docker run -d -p 8010:80 --name apache-test apache:new

通过运行这个命令，你将在Docker中启动一个服务器，并将其映射到主机的端口，这样你就可以通过客户端连接到主机的端口来访问容器中的服务。
[root@localhost tomcat]# docker ps -a
