Docker containers- running new java8 code on old java6 version

I have a new java8 web application(spring boot) that needs to run on a one of the old environment application boxes which has java 6.

java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03, mixed mode)

Distributor ID: Ubuntu
Description:    Ubuntu 12.04.5 LTS
Release:    12.04
Codename:   precise

i am amateur in docker's usage, but heard that you run the app inside the Docker container and give the config you want.In this case i want to run java8 on already installed java6.

please suggest is it possible? if so provide some references to start.

The java6 installed on your old environment doesn't matter.

If you can install docker on that environment, then you can create a docker image which contains java8, put your application in it and launch it on the server.

You can try it by launching

docker run -ti --rm livingobjects/jre8:8u71 java -version

on your "old" server, it will give you an output like this:

java version "1.8.0_71"
Java(TM) SE Runtime Environment (build 1.8.0_71-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.71-b15, mixed mode)
