How to Install Radius

Radius runs as a control plane on a Kubernetes cluster with a command-line interface for performing Radius commands. This guide covers how to install and configure each component required to run Radius. This includes:

• How to install the Radius CLI on your workstation.
• How to install the Radius control plane on a Kubernetes cluster.
• How to configure cloud providers to deploy to AWS and Azure.
• How to set up a developer workstation to use Radius.
• How to configure access to the Radius Dashboard.

System requirements

To install and run the Radius control plane you need:

• A Kubernetes cluster running a currently supported version. Radius tracks the upstream Kubernetes version support policy, which maintains the three most recent minor releases.
• kubectl installed and configured with a context pointing to your target cluster.
• Cluster-administrator (cluster-admin) access to the cluster. Radius installs CRDs, namespaces, RBAC resources, and an aggregated API server, all of which require cluster-wide privileges.
• Outbound network access from the cluster to pull the Radius container images and Helm chart from ghcr.io.
• For local clusters (kind or k3d): a container runtime such as Docker Desktop with at least 8 GB of memory allocated.

Supported Kubernetes clusters

Radius is tested and validated against the following Kubernetes distributions:

• Azure Kubernetes Service (AKS)
• Amazon Elastic Kubernetes Service (Amazon EKS)
• k3d
• kind

Organization

This guide is organized into a separate page for each component you install and configure: the Radius CLI, the control plane, cloud providers, a developer workstation, and the Dashboard. Start with the Radius CLI, then continue through the remaining pages in order.
