Minifying MicroShift image using docker-slim : Output Image is literally unusable

Expected Behavior

I was expecting to reduce the size of MicroShift image from 1.3GB to slightly lower.

Actual Behavior

However upon running docker-slimi the resultant image is 24MB but it is not usable. Docker-Slim removed every thing.

Steps to Reproduce the Problem

1. docker pull quay.io/microshift/microshift-aio
2. docker-slim build --http-probe=false quay.io/microshift/microshift-aio
3. docker images
4. The original imager is 1.3GB and the resultant image is 24MB , however the final image generated by docker-slim is not at all u sable.
5. To test you can launch microshift (which is a thin version of OpenShift )

docker run -d --rm --name microshift --privileged -v microshift-data:/var/lib -p 6443:6443 quay.io/microshift/microshift-aio

docker run -d --rm --name microshift --privileged -v microshift-data:/var/lib -p 6443:6443 quay.io/microshift/microshift-aio.slim

docker exec -it microshift /bin/bash
kubectl get nodes
kubectl get pods -A

6. If you get the output of the above 2 commands, it proves success

Reproduce the docker-slim build command against quay.io/microshift/microshift-aio with HTTP probing disabled, then inspect slim.report.json, creport.json, Dockerfile, and Dockerfile.fat from the reported artifacts. Compare the original and .slim images using the supplied docker run commands and kubectl get nodes and kubectl get pods -A; done means the minified image remains usable.
