从零开始构建Docker镜像_docker jdk镜像能从0开始嘛-优快云博客

这篇博客详细介绍了如何从零开始在CentOS7环境中构建包含JDK7和Tomcat7的Docker镜像。首先搭建Docker运行环境，然后准备基础镜像，接着下载并解压JDK7和Tomcat7安装包。在指定目录创建Dockerfile，并编写构建命令。最后，通过执行Docker命令构建镜像，并启动容器，验证镜像功能。

从零开始构建一个centos7+jdk7+tomcat7的镜像文件
centos7系统下docker运行环境的搭建准备centos基础镜像
docker pull centos
或者直接下载我准备好的镜像

docker pull registry.cn-hangzhou.aliyuncs.com/repos_zyl/centos:0.0.1

准备jdk7和tomcat7安装包

创建工作目录, mkdir -p /z/docker * 准备下载jdk7的tar.gz包, * wget http://download.oracle.com/otn/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz
解压到目录/z/docker下, 并重命名为jdk * wget http://mirrors.cnnic.cn/apache/tomcat/tomcat-7/v7.0.75/bin/apache-tomcat-7.0.75.tar.gz
解压到目录/z/docker下, 并重命名为tomcat
