I have a simple docker file that pulls node image and create a container where we run our application. Please find below the first line in our docker file.
FROM node:8
Other docker file commands to follow.
When I run node --version command inside the container it shows the version as 9.2.0 which is the latest node version.
Our host is EC2 running Ubuntu
uname -a
Linux ip.1.2.3.4-aws #50-Ubuntu SMP Wed Nov 15 22:18:17 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
