Exploring K3s as a lightweight Kubernetes distribution

As mentioned previously, throughout this book, and specifically in this chapter, we will utilize K3s, a lightweight Kubernetes distribution (https://k3s.io/), to run our examples.

K3s is particularly well-suited for scenarios where the full-scale implementation of Kubernetes may be too resource-intensive or complex.

Its lightweight nature makes it ideal for edge computing and IoT scenarios, where resources are often limited, and efficiency is paramount. In these environments, K3s provides the necessary Kubernetes features without the overhead. Additionally, solutions such as vCluster from Loft have leveraged K3s to run Kubernetes within Kubernetes, facilitating multi-tenancy on a host cluster. This approach allows for isolated Kubernetes environments within a single cluster, optimizing resource usage and offering scalability in multi-tenant setups. These use cases highlight K3s’s versatility and efficiency in diverse...
