Announcing Radius v0.59.0
Today we're happy to announce the release of Radius v0.59.0. Check out the highlights below, along with the full changelog for more details.
We would like to extend our thanks to all contributors who helped make this release possible!
Intro to Radius
If you're new to Radius, check out our website, radapp.io, for more information. Also visit our getting started guide to learn how to install Radius and create your first app.
Highlights
Radius Resource Types for compute platform extensibility
Note: the new Radius.Core/* Resource Types are actively under development and only available now as an early and sparsely documented preview. You may try the features by using the --preview flag in relevant CLI commands, please refer to the rad CLI reference for more details.
CLI support for the new Radius.Core resource types
Radius is introducing a new set of resource types under the Radius.Core namespace (e.g., Radius.Core/applications, Radius.Core/environments) that will eventually replace the existing Applications.Core types. These new types are available via the v20250801preview API surface and represent the next generation of Radius's resource model.
Currently, CLI commands like rad app list and rad app graph operate on the existing Applications.Core/applications type, meaning that applications deployed using the new Radius.Core/applications type were invisible to the CLI. The added --preview flag directs commands to operate against Radius.Core resources:
- rad app graph --preview and rad app status --preview — View the application graph and check status for apps deployed as Radius.Core/applications. (#11983)
- rad workspace create --preview — Create workspaces that use Radius.Core/environments, so you can pair them with the new resource types. (#11905)
Kubernetes namespace for Radius.Core environments
Previously, environments created with the Application.Core/environments created a new Kubernetes namespace on behalf of the user. We found that this approach was not representative of enterprise scenarios where namespace creation is managed by the cluster admins. New Radius.Core/environments require you to explicitly pass the Kubernetes namespace you want to use for application deployments, falling back to 'default' if none is specified.
Default Contour Gateway for route recipes
Radius now sets up Gateway API infrastructure automatically when Contour is installed. rad install kubernetes creates a shared GatewayClass/contour and Gateway/radius in radius-system, and the default Radius.Compute/routes recipe is pre-configured to attach route resources to this managed Gateway. Applications no longer need to define their own gateway resource in the default path.
Deprecation warning for rad run with extensible environments
The rad run command is not supported for environments configured with the new extensible Radius.Core/environments model and is planned for deprecation. rad run depends on Kubernetes-specific behaviors (including log streaming and port forwarding), making it incompatible with the platform-agnostic design of the new architecture, where compute runtimes can extend beyond Kubernetes. Instead, use rad deploy and rely on the native tooling of your chosen compute platform to access logs and establish connectivity.
Bug Fixes
- Fixed Helm chart Terraform binary path mismatch: The pre-mounted Terraform binary path in the Helm chart didn't match what the runtime expected, causing Radius to silently re-download Terraform from releases.hashicorp.com on every cold start. Now the paths are aligned and the pre-mounted binary is used correctly.
- Fixed recipe pack OCI tags: Core resource type recipes now use the full semantic version (e.g., 0.58.0) for OCI tags instead of the version channel (e.g., 0.40), aligning with the kube-recipes publishing pipeline.
- Aligned rad env create and rad env update flags: rad env create now supports cloud provider flags (--azure-subscription-id, --aws-region, etc.) and rad env update now supports --namespace, unifying the configuration options across both commands.
- Honor x-ms-client-flatten in Bicep type generator: The Bicep type generator now flattens the ARM .properties. envelope, so users write container.container.image instead of container.properties.container.image in their Bicep templates.
Upgrading to Radius v0.59.0
You can upgrade to this release by upgrading your Radius CLI then running rad upgrade kubernetes. Only incremental version upgrades are supported. Consult the upgrade documentation for full details.
