Feather code repository - Baseline CLOSER 2024 results

Feather

This is modified FLEDGE implementation based on the one written by Tom Goethals. It makes great use of virtual-kubelet to keep the code that is out of the scope of FLEDGE to a minimum.

Because source of the virtual-kubelet cli of is particularly useful, the code is used as a starting point.

Configuration

Certificates can be found on the master node at /etc/kubernetes/pki.

Building

Executing the provided script builds Feather for both arm64 and amd64.

$ ./scripts/build.sh

Deployment

Feather can either be deployed temporarily, or as a systemd service.

Temporarily

The scripts/deploy.sh script builds Feather and copies it over to the worker node. Currently the worker node is hard-coded as worker0, but this can be changed as required.

$ ./scripts/deploy.sh --log-level=info --config=default.json --provider=backend

Systemd Service

In order to persistently deploy Feather, it can be deployed as a systemd service. An example systemd configuration for this service is shown below.
