Create Docker container with both Java and Node.js

You can also use the node image and then install the default-jre:

# Dockerfile
FROM node:latest
RUN apt-get -y install default-jre

You can choose the version you need:

apt install default-jre
apt install openjdk-11-jre-headless
apt install openjdk-8-jre-headless

The best way for you is to take java (which is officially deprecated and it suggests you use openjdk image) and install node in it.

So, start with

FROM openjdk:latest

This will use the latest openjdk image, which is 8u151 at this time. Then install node and other dependencies you might need:

RUN apt-get install -y curl \
  && curl -sL https://deb.nodesource.com/setup_9.x | bash - \
  && apt-get install -y nodejs \
  && curl -L https://www.npmjs.com/install.sh | sh

You might want to install things like grunt afterwards, so this might come in handy as well.

RUN npm install -g grunt grunt-cli

In total you will get the following Dockerfile:

FROM openjdk:latest

RUN apt-get install -y curl \
  && curl -sL https://deb.nodesource.com/setup_9.x | bash - \
  && apt-get install -y nodejs \
  && curl -L https://www.npmjs.com/install.sh | sh \
RUN npm install -g grunt grunt-cli

You may clone the Dockerfile from my gitlab repo here

You can use single FROM per generated image. Try to use node as a base image and install java to it.

Dockerfile

FROM node:latest
RUN apt-get -y install default-jre

You can choose the version you need:

apt install default-jre
apt install openjdk-11-jre-headless
apt install openjdk-8-jre-headless

The FROM inside your dockerfile simply tells docker from which image it should start the configuration. You can't simply concatenate multiple images together. There are already multiple container images available which offer preinstalled Java 8 and node JS. I don't want to recommend any image specifically but will direct you to docker-hub for you to go search on your own and use the container that suites your needs the best.
