K3s remains our default Kubernetes distribution for edge computing needs and resource-constrained environments. It's a lightweight, fully compliant Kubernetes but with reduced operational overhead. It uses sqlite3 as the default storage backend instead of etcd. It has a reduced memory footprint because it runs all relevant components in a single process. We've used K3s in environments like industrial control systems and point-of-sale machines, and we're quite happy with our decision. With the K3s runtime containerd now supporting wasm, K3s can run and manage WebAssembly workloads directly, further reducing the runtime overhead.
K3s is a lightweight Kubernetes distribution built for IoT and edge computing. You get the benefits of a fully compliant Kubernetes but with reduced operational overhead. Its enhancements include lightweight storage backends (sqlite3 as default instead of etcd), a single binary package with minimal OS dependencies and reduced memory footprint, all of which make K3s suitable for resource-constrained environments. We've used K3s in point-of-sale machines, and we're quite happy with our decision.
K3s is a lightweight Kubernetes distribution built for IoT and edge computing. It's packaged as a single binary and has minimal to no OS dependencies, making it really easy to operate and use. It uses sqlite3 as the default storage backend instead of etcd. It has a reduced memory footprint because it runs all relevant components in a single process. It also achieves a smaller binary by stripping out third-party storage drivers and cloud providers that are not relevant for the K3s use cases. For environments with constrained resources, K3s is a pretty good choice and worth considering.
