fyc is an implementation of an App Container Executor per the App Container Spec.
This project has two goals:
- Do the least amout of isolation required to run an ACI (defined per the spec)
- Pass the ACE validator whose code is bundled with the spec
Right now, this means chrooting the application, setting some environment variables and providing a metadata service.
An executor MAY igore isolators that it does not understand and run the pod without them.
fyc remains a spec-compliant ACE despite not understanding any isolators. If the spec attempts to verify some well known isolators, fyc will fail these checks. These isolators might be implemented, eventually.
