Working example

Nobody has claimed this yet.

Hi. I'm struggling to get up and running with flintlock. The documentation has led me through all steps, I can see stdout of my firecraker instances via /var/lib/flintlock/vm/ns1/mvm1/01HN0B.... . however, I struggle to get a working json config. the provided https://github.com/weaveworks-liquidmetal/flintlock/blob/main/hack/scripts/payload/CreateMicroVM.json links a docker container that's 404, the provided images (capmvm-kubernetes:1.23.5) from the docs, with the rest of the configuration taken from CreateMicroVM.json , lead to systemd errors (dbus not found) and netplan apply fails, so my vm is offline, I also do not know how to connect to it via the console.

Seeing the same with the hammertime example.json

Start with hack/scripts/payload/CreateMicroVM.json and the hammertime example.json, then compare their referenced images and configuration with the supplied boot logs. Done means a documented JSON configuration starts a working VM with networking, and the documentation explains how to connect through the console.
