System Requirements

Astarte is a Native Kubernetes application, and as such Kubernetes is a hard requirement. It is possible to run Astarte outside Kubernetes, although a number of features won't be available - these setups are outside the scope of this document.

Kubernetes Requirements

Astarte requires at least Kubernetes 1.12 - however, it currently targets Kubernetes 1.16+. It is advised to consult Astarte Operator's compatibility matrix in the README to ensure a specific Kubernetes setup is supported.

The Astarte Operator does not require any unstable feature gate in Kubernetes 1.16, and is actively tested against KinD and major Managed Kubernetes installations on various Cloud Providers.

Resource Requirements

Depending on the kind of setup, Astarte might require different resource configurations when it comes to nodes. astartectl takes care of this with the profiles features, which inspects the Cluster and provides a set of ready made configurations for the Cluster. Besides this, Astarte requires a minimum of 3 physical nodes in case one is planning on a redundant setup.
