Setup

Prerequisties

3scale requires a RWX storage for the developer portal. We will leverage the OpenShift Data Foundation for this. The OpenShift Data Foundation needs atleast 3 worker nodes (is they are not configured on your cluster already, please follow the below steps)

Increase Worker Node Count

On your OpenShift Console UI, navigate to Administrator > Compute > Machine Sets and increase the machine count to 3 as shown below
Give it a few seconds to confirm the node is up and running

Ideally all this stuff would be setup during the configuration of your OpenShift Cluster.
For the purpose of this demo we are just building things from ground up

ODF Installation

The whole lab is going to leverage Operators for installation of all the components. Users can configure the operators either via cli or console.

On your OpenShift Console UI, navigate to Administrator > Operators > OperatorHub and search for OpenShift Data Foundation. Leave all the values as Default and click on install.

The operator installation might take a minute or two
Wait for the operator to install and when you see the below screen, click on Create StorageSystem
Make sure the gp2 StorageClass is selected and click Next
Select all the three nodes and leave all the other values as default. Click Next
Leave all the values as default. Click Next
Click on Create StorageSystem

3scale Installation

Create a 3scale namespace on your OpenShift Cluster. Navigate to Administrator > Project > Create Project. Type 3scale as the name of the project and create.
On your OpenShift Console UI, navigate to Administrator > Operators > OperatorHub and search for 3scale. Select the Red Hat Integration Operator - 3scale. Double check and make sure you are in the 3scale namespace while you do this
Click on Install
Double check and make sure the 3scale namespace is selected. Leave all the options as default and click Install
Once the installation is complete (will take a few seconds). Click on View Operator
Now let’s create the API manager. Deploying the APIManager custom resource will make the operator begin processing and will deploy a 3scale solution from it.
Click on the API Manager tab > Create APIManager > YAML view >. Remove the the existing yaml and copy paste the code provided in step 3 as shown below
```
apiVersion: apps.3scale.net/v1alpha1
kind: APIManager
metadata:
  name: 3scale
spec:
  system:
    fileStorage:
      persistentVolumeClaim:
        storageClassName: ocs-storagecluster-cephfs
    redisResources:
      limits:
        memory: 6Gi
  backend:
    redisResources:
      limits:
        memory: 6Gi
  wildcardDomain: %CLUSTER_WILDCARD_URL%
```
If the Cluster WildCard URL is not populated already in the above yaml, please enter it the respective text box above. You can find the cluster wildcard url dns of your OpenShift cluster from the Console URL. Make a note of the cluster wildcard url as it’ll be useful later
