Builds and packs a ubuntu container & runtime into a single shell script that can be run on any host with linux namespaces support
sudo bash ./build_container_hostarch.sh
sudo bash ./build_container_arm64.sh
will dump out a container.sh which is the runnable
Docker, wget, tar, internet access
tar, sh, awk, tail, sudo linux kernel with namespaces support
It creates a docker ubuntu:latest container, installs a few tools on it (see script if you wanna change)
exports the container and places it in a folder together with runc (a stand alone container runtime) and a configuration
file that gives the container access to everything on the host (only uses mount ns)
Then it downloads runc
Packs it all into a nice self extracting shell script and now you are good to go.
