Docker Desktop vs MicroK8s

Docker Desktop brings container development and deployment tools together for developers and teams. It includes Docker Engine, Docker CLI, Docker Compose, Docker Build, and Docker Kubernetes, with support for building images and Compose workflows. Its built-in Kubernetes environment lets users deploy, scale, test, and manage containerized applications locally without an external cluster. Docker Debug offers command-line diagnostics for containers and images, including slim containers, while Extensions allow third-party tools for debugging, testing, security, and networking. Downloads cover macOS with Apple Silicon or Intel, Windows with AMD64 or ARM64, and Linux; web is also listed as a platform. Docker Personal is free. Pro is $9 a month, Team is $15 a month, and Business is $24 a month. Paid-plan allowances and user limits differ. Business lists VDI support and additional security controls. Commercial use at companies with more than 250 employees or more than $10 million in annual revenue requires a paid subscription.

MicroK8s is a lightweight Kubernetes distribution that can run on a single node or scale to a high-availability production cluster. It is positioned for developer workstations, production, public clouds, edge deployments, IoT and embedded software-vendor platforms. The self-hosted distribution supports Linux, macOS and Windows, and packages upstream Kubernetes services in a minimal CNCF-certified distribution. Three or more nodes enable Dqlite-backed high availability and automatic recovery after a node failure. Strict confinement restricts workloads to explicitly granted files, system resources and hardware. Cluster API can automate cluster creation and lifecycle management through YAML manifests, including rolling HA upgrades. GPU workloads can use the NVIDIA GPU Operator, including NVIDIA Multi-Instance GPU. Official and community addons provide services such as DNS, certificate management, Prometheus, Istio and dashboards. Security updates apply automatically by default, with rollback on failure, and Kubernetes upgrades can be done with one command. MicroK8s has no license fees. Ubuntu Pro subscriptions are also listed, including $25 a year for a workstation subscription and $500 a year for a server subscription with unlimited VMs.
