[https://my.oschina.net/braveCS/blog/1504783 很值得参考 更新也有意思docker&k8s部署tomcat记录]

==docker hub==
<pre>
docker pull  tomcat:8.5

docker exec -it tomcat1 /bin/bash

三、部署应用

部署应用有两种方式：
1、挂载宿主主机上的应用目录

假如我们的应用在目录：/Users/apple/webapp目录下

docker run --privileged=true -v /data/web1:/usr/local/tomcat/webapps/demo -d -p 8080:8080 --name tomcat1 tomcat:8.5

    其中：–privileged=true是授予docker挂载的权限
    /data/web1 宿主主机目录
    /usr/local/tomcat/webapps/demo docker容器tomcat目录
    -p 端口映射
    –name 容器名称

==Dockerfile 构建==
<pre>

#创建目录tomcat,用于存放后面的相关东西。
mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf

webapps目录将映射为tomcat容器配置的应用程序目录
logs目录将映射为tomcat容器的日志目录
conf目录里的配置文件将映射为tomcat容器的配置文件

进入创建的tomcat目录，创建Dockerfile

==war包更新到容器 ==
<pre>
docker cp tomcataDemo.war 3cb492a27475 :/usr/local/tomcat/webapps #id

docker cp tomcatDemo.war tomcat1:/usr/local/tomcat/webapps  #name

#启动tomcat 或者重启 docker restart 【容器id】


docker restart    tomcat1

docker run -p 8081:8080 docker.io/tomcat


#cp 到母机
docker cp tomcat1:/usr/local/tomcat/webapps/examples/index.html .
