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.

Docker Compose and k3s belong to "Container Tools" category of the tech stack.

Docker Compose and k3s are both open source tools. Docker Compose with 16.6K GitHub stars and 2.56K forks on GitHub appears to be more popular than k3s with 7.81K GitHub stars and 483 GitHub forks.

    What are some alternatives to Docker Compose and k3s?
    Kubernetes
    Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
    Docker
    The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere
    Docker Swarm
    Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.
    Helm
    Helm is the best way to find, share, and use software built for Kubernetes.
    Ansible
    Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. Ansible’s goals are foremost those of simplicity and maximum ease of use.
