Allow to set kubelet configuration parameters
via an option. Additionally, expose the
respective options for graceful node
shutdown directly, as it is anticipated to
be used frequently.
This contribution extends the k3s module to
enable the usage of Helm charts and container
images in air-gapped environments. Additionally,
the manifests option allows to specify arbitrary
manifests that are deployed by k3s automatically.
It is now possible to deploy Kubernetes workloads
using the k3s module.
Since https://github.com/NixOS/nixpkgs/issues/213943 got fixed, only the main k3s derivation is tested.
Here I changed the tests a bit to make them test all provided k3s derivations
