Installing IBM Redis

You must install Redis operator if you want to run the IBM Process Mining application with replicas.

To deploy and configure Redis, do the following steps:

Deploy the Redis catalog with the following command:

cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: ibm-redis-cp-catalog
  namespace: ${PM_PROJECT}
spec:
  displayName: ibm-redis-cp-1.4.0
  publisher: IBM
  image: icr.io/cpopen/ibm-redis-cp-operator-catalog@sha256:d194a69150504735f5142099bcb97bd4767cf252dfe0d9fa4bb9fe4f6fb18618
  sourceType: grpc
EOF

Create a subscription on your namespace with the following command:

cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: redis-pm-subscription
  namespace: ${PM_PROJECT}
spec:
  channel: v1.3
  installPlanApproval: Automatic
  name: ibm-redis-cp
  source: ibm-redis-cp-catalog
  sourceNamespace: ${PM_PROJECT}
EOF

Verify the installation with the following commands:
```
oc get operators
```
If Redis was installed successfully, you will see the following installed operators:
```
NAME                                  AGE
ibm-redis-cp.<your namespace>         29m
```
Change your processmining instance configuration with the following settings to connect it to Redis:
```
processmining:
  replicas:
    analytics: 2
  storage:
    redis:
      install: true
```
