notes on firecracker microvms

by gwynplaine

As a part of my stage at a lab, I needed to know how to operate firecracker microvms and have an idea of how they work.

So here I present an ordered list of resources not only to get started with firecracker but also tu understand a little about what it is happening at a lower level.

This list will change as I discover more resources.

  2. firecracker-docs-network-setup network. routes. firewall.
