Frequently asked
Docker alternatives FAQ
- Is Docker free?
- Docker Personal is free at $0 for individual developers, and Docker Engine itself is open source. Paid plans start with Docker Pro at $9 per user per month billed yearly, or $11 billed monthly, and scale up through Team and Business tiers.
- What is the best free Docker alternative?
- Podman is the closest free replacement for day-to-day container work, and it is free and open source under the Apache License 2.0. It runs containers rootless by default and is largely command-line compatible with Docker. containerd and CRI-O are the lower-level runtimes if you need the engine rather than the developer experience.
- Can I switch from Docker to Podman without changing my workflow?
- Mostly. Podman is designed to be compatible with Docker commands and supports Kubernetes-style pods, and the vendor states it works with tooling including Visual Studio Code and GitHub Actions. Some Docker-specific features and Compose behaviour still differ, so expect to test your pipelines rather than assume a drop-in swap.
- Do I need Docker if I already run Kubernetes?
- No. Kubernetes talks to a container runtime through the CRI interface, and containerd and CRI-O both implement it directly. Docker is not required on Kubernetes nodes, which is why many clusters dropped the Docker shim.
