Docker Compose vs k3s: What are the differences?
Docker Compose: Define and run multi-container applications with Docker. With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running; k3s: Lightweight Kubernetes. 5 less than k8s (by Rancher Labs). Certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. Supports something as small as a Raspberry Pi or as large as an AWS a1.4xlarge 32GiB server.
