K3s offers lightweight alternative to full Kubernetes

Running standard Kubernetes is powerful but heavy, requiring lots of components and maintenance. K3s, originally from Rancher Labs and now under SUSE, is a lightweight Kubernetes distribution that shrinks the setup to a single small binary—under 100 MB—and simplifies deployment, even for devices like Raspberry Pi. It’s best for smaller teams or simpler infrastructure, but the trade-off is less flexibility than full Kubernetes.

• K3s condenses Kubernetes to a single binary under 100 MB
• It supports simplified deployment and management
• Runs on minimal hardware, including Raspberry Pi
• Less operational overhead than standard Kubernetes
• Some advanced Kubernetes features may not be available
