View Source 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.
Astarte requires at least Kubernetes 1.19, and strives to be compatible with all newer Kubernetes versions. 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 1.19, and is actively tested against KinD and major Managed Kubernetes installations on various Cloud Providers.
Astarte Operator requires
cert-manager to enable Webhooks. This documentation will
detail all needed steps for installing
cert-manager in the cluster in case it's not installed yet.
Depending on the kind of setup, Astarte might require different resource configurations when it comes to nodes. In addition, if one is planning on a redundant setup, a minimum of 3 physical nodes is required.
To spin up a testing instance you should allocate at least 4 vCPU and 8GB of memory just for Astarte. Please keep in mind that additional applications running within the cluster and the Kubernetes overhead itself must be accounted when sizing your Astarte cluster.
