Description

This is a simple testcase to determine whether docker containers run properly on an Atomic Host.

Prerequisite
This testcase assumes you have already ran the boot test.

Setup

  1. Ensure you have a booted working Atomic Host

How to test

  1. Run a dockerized application
  2. Example:
docker run -it --rm docker.io/busybox true && echo "PASS"

Expected Results

  1. Output from the example command should resemble:
# docker run -it --rm docker.io/busybox true && echo "PASS"
Unable to find image 'docker.io/busybox:latest' locally
