Installing Runtime Fabric on EKS, AKS, and GKE Using rtfctl

You can use the Runtime Fabric command line tool, rtfctl, to install Anypoint Runtime Fabric on an Amazon Elastic Kubernetes Service (Amazon EKS), Azure Kubernetes Service (AKS) or Google Kubernetes Engine (GKE) installation that you manage.

Before you Begin

Before installing Anypoint Runtime Fabric in a Kubernetes environment, ensure:

You have reviewed the architecture and requirements outlined in Runtime Fabric
You have configured your network to support Runtime Fabric
You have installed and configured your Kubernetes environment with:
- An EKS, AKS, or GKE Kubernetes environment. Other Kubernetes environments are not supported.
- A supported Kubernetes version.
- An ingress controller to send external requests to applications.
You create your clusters using the latest Runtime Fabric agent version available. If you can’t do so, refer to How to Specify the RTF Agent Version in Upgrades.

If you want to use a local registry with Runtime Fabric, follow the installation instructions in Using a Local Registry with Runtime Fabric. You must set up the local registry during installation.

Create a Runtime Fabric using Runtime Manager

To install Runtime Fabric, first create a Runtime Fabric using Runtime Manager. This is required to obtain the activation data which is needed during installation.

From Anypoint Platform, select Runtime Manager.
Click Runtime Fabrics.
Click Create Runtime Fabric.
Enter the name of the new Runtime Fabric, then select one of the following options:
- Amazon Elastic Kubernetes Service
- Azure Kubernetes Service
- Google Kubernetes Engine
Click Next.
Click rtfctl.
Review the Support responsibility disclaimer, then if you agree click Accept.

Runtime Manager creates the Runtime Fabric and displays the Activation State page. This page displays the activation data used to install Runtime Fabric on a Kubernetes service. Copy this data to the clipboard for use in the next section.

Download the rtfctl Utility

Runtime Fabric uses the rtfctl command-line utility for installation and management tasks. See Install the Runtime Fabric Command Line Tool.

Download the rtfctl command-line utility:

rtfctl is supported on Windows, MacOS (Darwin), and Linux. Choose the appropriate method:

Windows

curl -L https://anypoint.mulesoft.com/runtimefabric/api/download/rtfctl-windows/latest -o rtfctl.exe

MacOS (Darwin)

curl -L https://anypoint.mulesoft.com/runtimefabric/api/download/rtfctl-darwin/latest -o rtfctl

Linux

curl -L https://anypoint.mulesoft.com/runtimefabric/api/download/rtfctl/latest -o rtfctl

Change file permissions for the rtfctl command-line utility:
```
sudo chmod +x rtfctl
```

Install Runtime Fabric

After creating a Runtime Fabric in Runtime Manager and obtaining the activation data, install Runtime Fabric into your Kubernetes service using the rtfctl command-line utility.

If your Kubernetes configuration is not located in the \~/.kube/config directory, set the KUBECONFIG environment variable before running rtfctl:

export KUBECONFIG=<path-to-kubeconfig>

Validate that your Kubernetes environment is ready for installation:
```
rtfctl validate <activation_data>
```
The validate option verifies that:
- The Kubernetes environment is running.
- All required components exist.
- All required services are available.
  
  The rtfctl command-line utility outputs any incompatibilities with the Kubernetes environment.
Install Runtime Fabric:
```
rtfctl install <activation_data>
```
<activation_data> is the activation data obtained after creating the Runtime Fabric using Runtime Manager. During installation, the rtfctl utility displays any errors encountered.

Insert the Mule License Key

If you didn’t add the Mule license key during install, you can add it using the rtfctl command line utility or Helm.

Before you install the license key, encode it to Base64 format.

Encode the License Key

On MacOS, run the following command:

BASE64_ENCODED_LICENSE=$(base64 -b0 license.lic)

On Unix, run the following command:

BASE64_ENCODED_LICENSE=$(base64 -w0 license.lic)

On Windows, choose one of the following:
- Use a WSL or Cygwin shell that includes the base64 tool and use the above Unix command.
- Use the base64.exe program included with Windows git (C:\Program Files\Git\usr\bin).
- Use the following Powershell command:
  $BASE64_ENCODED_LICENSE=[convert]::ToBase64String((Get-Content -path "license.lic" -Encoding byte))

Apply the License Key Using rtfctl

On the controller node acting as the leader during installation (the installer node), run the following command:
```
rtfctl apply mule-license $BASE64_ENCODED_LICENSE
```
You can also apply the Mule license providing the file path directly:
```
rtfctl apply mule-license --file /path/to/license.lic
```
To verify the Mule license key has applied correctly, run:
```
rtfctl get mule-license
```

Apply the License Key Using Helm

To apply the license using Helm, run the following command:

helm upgrade --set muleLicense=$BASE64_ENCODED_LICENSE

Configure the Ingress Resource Template

If your ingress controller requires custom annotations and ingress class definition, follow the instructions in Defining a Custom Ingress Configuration.

For GKE customers, the ingress controller included with GKE will provision a separate HTTP load balancer per application by default. Please read this KB article for more details.

Validate Your Runtime Fabric

After completing the installation, your Runtime Fabric should be activated within your Anypoint organization. To validate your installation, go to Anypoint Runtime Manager and confirm that the status of the Runtime Fabric is Active.

Before deploying an application to your Runtime Fabric:

Associate the Runtime Fabric with at least one Anypoint environment.
Review and update the Inbound Traffic settings based upon your Kubernetes environment.
Deploy an application to verify that Runtime Fabric is installed and configured correctly.
