Installing Runtime Fabric on Red Hat OpenShift

You can install Anypoint Runtime Fabric on a Red Hat OpenShift installation.

Runtime Fabric supports the following Red Hat OpenShift deployment options:

Red Hat OpenShift Service on AWS
Microsoft Azure Red Hat OpenShift
Red Hat OpenShift Dedicated
Red Hat OpenShift on IBM Cloud
Self-managed Red Hat OpenShift editions (Performance Plus, OCP, Kubernetes engine)

Runtime Fabric supports Red Hat OpenShift versions 4.6 to 4.10.

Install Runtime Fabric on Red Hat OpenShift

When you install Runtime Fabric on Red Hat OpenShift, you’ll:

Create a Runtime Fabric using Runtime Manager
Create a namespace for Runtime Fabric
Create a Docker pull secret for pulling the Runtime Fabric component images
Optionally, configure shared tenancy
Install and configure the Runtime Fabric operator
Complete the remaining installation steps to validate your Runtime Fabric and configure ingress

Before You Begin

Before installing Runtime Fabric on Red Hat OpenShift, ensure that:

You have reviewed the architecture and requirements outlined in Runtime Fabric on Self-Managed Kubernetes
You have reviewed the network requirements
You have installed and configured a supported Red Hat OpenShift Kubernetes environment with:
- A supported Kubernetes version
- An ingress controller to send external requests to applications
You have privileged user permissions to complete the installation process
You have access to the following URLs needed for Red Hat OpenShift registry:
- registry.connect.redhat.com (See the Red Hat Container Registry Authentication)
- https://rhc4tp-prod-z8cxf-image-registry-us-east-1-evenkyleffocxqvofrk.s3.dualstack.us-east-1.amazonaws.com

Create a Runtime Fabric using Runtime Manager

To install Runtime Fabric on Red Hat OpenShift, 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 the Red Hat OpenShift option.
Review the Support responsibility disclaimer, then if you agree click Accept.
Click Operator.
Copy the activation data.

Create A Namespace for Runtime Fabric

You must create a namespace named rtf in your Kubernetes cluster. This namespace is where you install Runtime Fabric components.

To create the namespace, run:

oc create ns rtf

Create A Docker Pull Secret

After you create the namespace, create a pull secret so you can retrieve the Docker images needed to install and run Runtime Fabric.

The default registry URL is rtf-runtime-registry.kprod.msap.io. If you’re using a local registry, specify those values here.

To create the pull secret, run:

oc create secret docker-registry <pull_secret> --namespace rtf --docker-server=<docker_registry_url> --docker-username=<docker_registry_username> --docker-password=<docker_ registry_password>

(Optional) Configure Authorized Namespaces

You can optionally configure authorized namespaces, which enable you to deploy Runtime Fabric alongside other services in a Kubernetes cluster.

Before You Begin

Before configuring authorized namespaces, note the following:

You must create the authorized-namespaces ConfigMap file before installing Runtime Fabric. Additionally, you must name the ConfigMap, authorized-namespaces.

The rtf:resource-metrics-collector ClusterRole has cluster-wide permissions to get and list nodes, pods, and namespaces and has watch permissions for nodes. The role ClusterRole is defined as follows:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: rtf:resource-metrics-collector
  labels:
    {{- include "labels.standard" . | nindent 4 }}
rules:
  - apiGroups: [""]
    resources: ["nodes", "pods", "namespaces"]
    verbs: ["list", "get"]
  - apiGroups: [""]
    resources: ["nodes"]
    verbs: ["watch"]

In your cluster, create an additional namespace for application deployments, and add the necessary labels to the namespace. To do so, create a YAML file with the following contents:

apiVersion: v1
kind: Namespace
metadata:
    name: <namespace>
labels:
    rtf.mulesoft.com/envId: <ENVIRONMENT-ID>
    rtf.mulesoft.com/org: <ORG-ID>
    rtf.mulesoft.com/role: workers

Apply the file you just created:
```
oc apply -f <filename>.yaml
```
Repeat steps 1 and 2 to add as many namespaces as you need.

Create the RoleBinding for the Runtime Fabric agent ClusterRole that includes the Runtime Fabric agent ServiceAccount. To do so, apply the following configuration in your additional namespace:

kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: <name>
  namespace: <additional-namespace>
subjects:
  - kind: ServiceAccount
    name: rtf-agent
    namespace: rtf
roleRef:
  kind: ClusterRole
  name: rtf:agent
  apiGroup: rbac.authorization.k8s.io

In your cluster, create a ConfigMap file named authorized-namespaces and list any additional namespaces:

apiVersion: v1
kind: ConfigMap
metadata:
  name: authorized-namespaces
  namespace: rtf
data:
  ADDITIONAL_NAMESPACE: "additional-namespace1"
  ADDITIONAL_NAMESPACE: "additional-namespace2"

If, after fully installing Runtime Fabric, you later add or delete any namespaces from the ConfigMap, you must restart the Runtime Fabric agent pod. To do so, run the following command:
```
oc -nrtf delete po -l app=agent
```
After you delete the pod, Kubernetes starts a new one.

Install the Red Hat OpenShift Runtime Fabric Operator

You install the Runtime Fabric operator (rtf-agent-operator) from the OperatorHub.

In the Red Hat OpenShift console, navigate to Operators > OperatorHub.
In the OperatorHub search field, search for the Runtime Fabric operator.
In the rtf-agent-operator dialog, click Install.

Installing the Runtime Fabric operator requires manual approval and may take several minutes to complete.

Configure the Runtime Fabric Operator

To configure the Runtime Fabric operator, you supply the necessary values when prompted.

In the Red Hat OpenShift console, navigate to Operators > Installed Operators.
In the console, switch the value of Project to the namespace you created for installing Runtime Fabric.
In the console, click Create Instance, and select Configure via form view.

Do not change the name of the instance. Doing so can create installation errors.
Add any required parameters. Refer to the Installation Parameters Reference for guidance.

If you’re using authorized namespaces, set authorizedNamespaces to true.
Click Create.

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.

Prepare for Deploying Mule Apps to Red Hat OpenShift

Before you deploy any Mule applications to your Red Hat OpenShift cluster, ensure that you’ve installed your Mule license key and then, perform the following steps.

Also, before attempting to deploy an Mule applications, ensure that you’ve installed your Mule license key.

Create a namespace for your Mule app deployments. See Creating Application Namespaces for Application Deployments.
From Runtime Manager, deploy a Mule app using your namespace. See Deploy Mule Applications to Runtime Fabric for instructions.
