下载jdk 1.8

选择适合自己的jdk下载，linux版本选择下载 *.tar.gz

在服务器中/home目录一般是空间最大的目录,选择此目录创建镜像仓库

mkdir /home/docker/jdk

cd /home/docker/jdk

wget jdk下载地址

创建dockerfile文件

vim Dockerfile                                                         

文件内容如下:

#依赖镜像名称和ID   使用  docker images 查看镜像和其id
FROM centos:7
#创建安装文件夹
RUN mkdir  /usr/local/java
#A相对路径jar包添加到目录下
ADD jdk-8u211-linux-x64.tar.gz /usr/local/java/

#java环境变量
ENV JAVA_HOME /usr/local/java/jdk1.8.0_211
ENV JRE_HOME $JAVA_HOME/jre
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH
