kandi X-RAY | systemk Summary

systemk is a Go library. systemk has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a virtual kubelet provider that uses systemd as its backend. Every Linux system has systemd nowadays. By utilizing K3s (just one Go binary) and this virtual kubelet you can provision a system using the Kubernetes API. The networking is the host's network, so it make sense to use this for more heavy weight (stateful?) applications. The filesystem is semi hidden, but emptyDir and the like works. It is hoped this setup allows you to use the Kubernetes API without the need to immerse yourself in the (large) world of kubernetes (overlay networking, ingress objects, etc., etc.). However this does imply networking and discovery (i.e. host) DNS is already working on the system you're deploying this. How to get a system into a state it has, and can run, k3s and systemk is an open questions (Ready made image? A tiny bit of config mgmt?). Systemk will use systemd to start pods as service unit(s). This uses the cgroup implementation systemd has. This allows us to set resource limits, by specifying those in the unit file (copy paste from the podSpec almost). Generally there is no (real container) isolation in this setup - although for disk access things are fairly contained, i.e. /var/secrets/kubernets.io/token will be bind mounted into each unit. You basically use the k8s control plane to start linux processes. There is also no address space allocated to the PODs specially, you are using the host's networking. "Images" are referencing (Debian) packages, these will be apt-get installed. Discovering that an installed package is no longer used is hard, so this will not be done. systemk will reuse the unit file that comes from this install, almost exclusively to find the ExecStart option. A lot of extra data is injected into it to make it work fully for systemk. If there isn't an unit file (e.g. you use bash as the image), a unit file will be synthesized. Each scheduled unit will adhere to a naming scheme so systemk knows which ones are managed by it.
