Docker:JDK镜像制作

1.下载JDK

• jdk-8u221-linux-x64.tar.gz

2.创建Dockerfile

• 新建一个jdk文件夹方便打包

mkdir ~/jdk

# 把jdk放进去
chao@localhost:~$ cp jdk-8u221-linux-x64.tar.gz ./jdk
chao@localhost:~$ cd jdk
chao@localhost:~/jdk$ ls
Dockerfile  jdk-8u221-linux-x64.tar.gz
chao@localhost:~/jdk$

• 进入jdk目录下，构建Dockerfile文件

# This is a JDK servic docker
FROM centos
MAINTAINER chao
ADD jdk-8u221-linux-x64.tar.gz /usr/local

ENV JAVA_HOME /usr/local/jdk1.8.0_221
ENV JRE_HOME /usr/local/jdk1.8.0_221/jre
ENV PATH $JAVA_HOME/bin:$PATH

3.使用Dockerfile构建jdk镜像

docker build -t jdk-8u221:v1 .

chao@localhost:~/jdk$ docker build -t jdk-8u221:v1 .

4.查看镜像

chao@localhost:~/jdk$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
jdk-8u221           v1                  87c2abc2bff8        47 seconds ago      609MB
centos              latest              9f38484d220f        5 months ago        202MB

5.进入容器验证java环境

chao@localhost:~/jdk$ docker run -it jdk-8u221:v1 /bin/bash
[root@9bad7b732e5d /]# java -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

可看到，jdk镜像中的java环境已经配置完成
