dokcer通过 Dockerfile 构建部署tomcat图文详解

首先创建tomcat目录，用于存放文件。

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 vi Dockerfile

通过Dockerfile创建一个镜像，替换成你自己的名字

docker build -t tomcat .

创建完成后，可以查询中创建的镜像

docker images|grep tomcat

docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat
