A container runtime

Learning how 2 container.

Testing

The steps:

• Create an OCI Bundle
• Run commands against that bundle

How To Create an OCI Bundle

mkdir <img-name>
mkdir <img-name>/rootfs
docker pull <img-name>
docker create --name tmp<img-name> <img-name>
docker export tmp<img-name> | tar -C <img-name>/rootfs -xf -
docker rm tmp<img-name>
cd <img-name>
runc spec

This will leave you with a root filesystem and a config.json in the directory.
