檢視Tomcat映象：

這裡列出了許多，但是我一般找官方的那個[official 是OK的]。
[root@VM-0-4-centos ~]# docker pull tomcat:8.5.66 8.5.66: Pulling from library/tomcat d960726af2be: Already exists e8d62473a22d: Already exists 8962bc0fad55: Already exists 65d943ee54c1: Already exists da20b77f10ac: Already exists fb6a778e6477: Pull complete ae7884f0e61b: Pull complete 5a229cc6592e: Pull complete 1c2d6d25c04a: Pull complete 39b99cdc3584: Pull complete Digest: sha256:9ac86d435387421c839a4456a34a55fffc230701f1b40563409e589650b556f9 Status: Downloaded newer image for tomcat:8.5.66 docker.io/library/tomcat:8.5.66
tomcat為了安全，8.5.2在之後的版本webapps下面預設是空的。據說8.5.2版本沒有這個問題。
建立容器
[root@VM-0-4-centos ~]# docker run -d --name tomcat_test -p 8081:8080 tomcat:8.5.66 -v /usr/local/tomcat/webapps:/www
WARNING: IPv4 forwarding is disabled. Networking will not work.
c6a7bee051670d484db8fb1a1754ae59ac5a4da0c67bc9ec3c07a52e108bc2eb
提示說是ipv4轉發未啟用，這個先不管。
/usr/local/tomcat/webapps是docker容器裡的路徑
/www是宿主機路徑
看一下運行了嗎
[root@VM-0-4-centos ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c6a7bee05167 tomcat:8.5.66 "catalina.sh run" 4 minutes ago Up 4 minutes 0.0.0.0:8081->8080/tcp, :::8081->8080/tcp tomcat_test
需要將這兩個路徑的檔案複製出來，當然也可以直接進入改，但是我個人比較喜歡複製出來，然後把容器的路徑映射出來。不知道為什麼tomcat的容器沒有這樣的選項，必須要先複製出來再對映，否則會報錯。
把docker容器內部的檔案複製到本地
docker cp c6a7bee05167:/usr/local/tomcat/conf /path/filename
docker cp c6a7bee05167:/usr/local/tomcat/conf /path/filename
/usr/local/tomcat/conf
這是配置檔案路徑
/usr/local/tomcat/webapps
這是一些預設網站路徑
