1, Dockerfile:


wget http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz


2. New Docker Source


Vim Dockerfile


From Daocloud.io/library/ubuntu:latest
Env Timedate 2017-05-24


3. Copy the JDK package into the mirror


From Daocloud.io/library/ubuntu:latest
Env Timedate 2017-05-24
Add Jdk1.8.0_131/home
Env java_home/home/jdk1.8.0_131
Env PATH $PATH: $JAVA _home/bin: $JAVA _home/db/bin: $JAVA _home/jre/bin




(The jdk1.8.0_131 folder overwrites the home directory in the image, where the tar package is cached to solve the problem)




4. Build Dockerfile




Docker build-t java8:first-f Dockerfile.








5, the implementation of the image;


Docker run-d-P 80:8080-p 2222:22 java8:first/sbin/init
