Radius Environments are prepared landing zones for applications that contain configuration and Recipes. To learn more visit the environments overview page.

Radius Environments can be setup with the rad CLI via two paths: interactive or manual.

Pre-requisites

• Setup a supported Kubernetes cluster
• rad CLI
• Bicep VSCode extension

Create a development environment

1. Initialize a new Radius Environment with rad init:

   rad init
   

   Select Yes to setup the application in the current directory. This will create app.bicep and bicepconfig.json files

   Initializing Radius...
   
   🕔 Install Radius v0.41
      - Kubernetes cluster: kind
      - Kubernetes namespace: radius-system
   ⏳ Create new environment default
      - Kubernetes namespace: default
      - Recipe pack: local-dev
   ⏳ Scaffold application
   ⏳ Update local configuration
   

2. Verify the initialization by running:

   kubectl get deployments -n radius-system
   

   You should see:

   NAME                      READY   UP-TO-DATE   AVAILABLE   AGE
   ucp                       1/1     1            1           53s
   appcore-rp                1/1     1            1           53s
   bicep-de                  1/1     1            1           53s
   contour-contour           1/1     1            1           46s
   

   You can also use rad env list to view your environment:

   rad env list
   

3. Use rad recipe list to see the list of available Recipes:

   rad recipe list
   

   NAME      TYPE                              TEMPLATE KIND  TEMPLATE
   default   Applications.Datastores/mongoDatabases  bicep          ghcr.io/radius-project/recipes/local-dev/mongodatabases:latest
   default   Applications.Datastores/redisCaches     bicep          ghcr.io/radius-project/recipes/local-dev/rediscaches:latest
   

   You can follow the Recipes documentation to learn more about the Recipes and how to use them in your application.

Create an environment interactively

1. Initialize a new environment with rad init --full:

   rad init --full
   

2. Follow the prompts, specifying:

   • Namespace - The Kubernetes namespace where your application containers and networking resources will be deployed (different than the Radius control-plane namespace, radius-system)
   • Azure provider (optional) - Allows you to deploy and manage Azure resources
   • AWS provider (optional) - Allows you to deploy and manage AWS resources
   • Environment name - The name of the environment to create

   You should see the following output:

   Initializing Radius...
   
   ✅ Install Radius v0.41
      - Kubernetes cluster: k3d-k3s-default
      - Kubernetes namespace: radius-system
   ✅ Create new environment default
      - Kubernetes namespace: default
      - Recipe pack: dev
   ✅ Scaffold application samples
   ✅ Update local configuration
   
   Initialization complete! Have a RAD time 😎
   

3. Verify the Radius services were installed by running:

   kubectl get deployments -n radius-system
   

   You should see:

   NAME              READY   UP-TO-DATE   AVAILABLE   AGE
   ucp               1/1     1            1           2m56s
   appcore-rp        1/1     1            1           2m56s
   bicep-de          1/1     1            1           2m56s
   contour-contour   1/1     1            1           2m33s
   

4. Verify an environment was created with rad env show:

   rad env show -o json
   

   You should see your new environment:

   {
     "id": "/planes/radius/local/resourcegroups/default/providers/Applications.Core/environments/default",
     "location": "global",
     "name": "default",
     "properties": {
       "compute": {
         "kind": "kubernetes",
         "namespace": "default"
       },
       "provisioningState": "Succeeded",
       "recipes": {}
       }
     },
     "systemData": {},
     "tags": {},
     "type": "Applications.Core/environments"
   }
   

Create an environment manually (advanced)

Radius can also be installed and an environment created with manual rad CLI commands. This is useful for pipelines or scripts that need to install and manage Radius.

1. Install Radius onto a Kubernetes cluster:

   Run rad install kubernetes to install Radius into your default Kubernetes context and cluster:

   rad install kubernetes
   

   You should see the following message:

   Installing Radius version 2134e8e to namespace: radius-system...
   

2. Create a new Radius resource group:

   Radius resource groups are used to organize Radius resources such as applications, environments, portable resources, and routes. Run rad group create to create a new resource group:

    rad group create myGroup
   

   You should see the following message:

    creating resource group "myGroup" in workspace ""...
   
    resource group "myGroup" created
   

3. Create your Radius Environment:

   Run rad env create to create a new environment in your resource group. Specify the --namespace flag to select the Kubernetes namespace to deploy resources into:

   rad env create myEnvironment --group myGroup --namespace my-namespace
   

   You should see your Radius Environment being created and linked to your resource group:

   Creating Environment...
   Successfully created environment "myEnvironment" in resource group "myGroup"
   

4. Verify the initialization by running:

   kubectl get deployments -n radius-system
   

   You should see:

   NAME              READY   UP-TO-DATE   AVAILABLE   AGE
   ucp               1/1     1            1           2m56s
   appcore-rp        1/1     1            1           2m56s
   bicep-de          1/1     1            1           2m56s
   contour-contour   1/1     1            1           2m33s
   

   You can also use rad env list to see if the created environment gets listed:

   rad env list --group myGroup
   

   You should see:

   NAME
   myEnvironment
