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" 

or,

podman 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

1. Ensure that the docker daemon is using the overlay2 storage driver set up by container-storage-setup
