Silverkube - a kubernetes service for desktop

The goal is to provide a kubernetes service suitable to manage a desktop workstation:

• Minimal services to be started early.
• Basic auth enough to let a container starts more containers.

This process is pretty much an experimental work in progress, use at your own risk.

Note that running the display server in a kubernetes pod presently does not work rootless. It seems like systemd-login does some magic to authorize this, and it is not clear if and how that can be forwarded to the kubelet context.

Install

• On a fedora-36 system, install the pre-built package:

sudo dnf install -y $SILVERKUBE_RPM_RELEASE_URL

• Or build the package locally using:

python3 build.py

• Or build the package inside a container:

mkdir -p ~/.cache/silverkube
podman run --rm -it \
  -v $HOME/.cache/silverkube:/root/.cache/silverkube:Z \
  -v $(pwd):/data:Z --workdir /data \
  registry.fedoraproject.org/fedora:33 python3 build.py

Usage

• Make sure the hostname resolve to localhost, and run systemctl stop systemd-resolved

• Start the services rootless

$ silverkube start
[...]
up!
alias kubectl='/home/fedora/.local/bin/rootless-join kubectl --kubeconfig /home/fedora/.config/silverkube/kubeconfig'

• Or start the services as root

$ sudo silverkube start
[...]
up!
alias kubectl='kubectl --kubeconfig /etc/silverkube/kubeconfig'

• Stop the services using stop argument
