创建镜像
[root@docker43 tomcat_web]# docker build -t tomcat_web:v1 . 查看镜像
[root@docker43 tomcat_web]# docker images

创建项目目录
我们是基于tomcat_web镜像进行创建容器的
首先我先在宿主机上创建个项目的目录(server.xml的配置文件拷贝改路径就能用)
[root@docker43 ~]# cd /home/
[root@docker43 home]# mkdir test.tomcat.com && cd test.tomcat.com
[root@docker43 test.tomcat.com]# touch server.xml # 配置文件
[root@docker43 test.tomcat.com]# mkdir logs # 日志目录
[root@docker43 test.tomcat.com]# mkdir wwwroot # 项目主目录(要是修改了记得也在server.xml进行修改)
[root@docker43 test.tomcat.com]# ll
总用量 0
drwxr-xr-x 2 root root 6 10月 6 18:03 logs
-rw-r--r-- 1 root root 0 10月 6 18:02 server.xml
drwxr-xr-x 2 root root 6 10月 6 18:03 wwwroot server.xml配置文件
