Dockerfile使用案例

# 下载centos基础镜像
FROM centos:latest
 
# 在镜像里运行的命令
RUN mkdir -p /usr/java/jdk1.6.0_45
# 将Dockerfile同目录下的jdk1.6.0_45文件复制到镜像中
ADD jdk1.6.0_45 /usr/java/jdk1.6.0_45
 
RUN mkdir -p /usr/java/apache-tomcat-6.0.53
ADD apache-tomcat-6.0.53 /usr/java/apache-tomcat-6.0.53

# 通过yum安装依赖库
RUN yum install libnsl vim -y
 
#添加环境变量
