Question: How can you install and configure Redis Enterprise on OpenShift?
Answer
To install and configure Redis Enterprise on OpenShift, you could use the Operator Framework. The Redis Enterprise Operator provides a simple way to deploy and manage your Redis Enterprise Cluster in an OpenShift environment.
Here is a step-by-step guide:
-
Prerequisites Ensure that you have an OpenShift cluster running with adequate resources, and you are logged into the cluster via 'oc' command line tool.
-
Install the Redis Enterprise Operator
First, create a new project where the operator will be installed:
oc new-project redis-enterprise
Then, apply the operator bundle YAML:
oc apply -f bundle.yaml
-
Configure the Redis Enterprise Cluster
After the Operator is installed, you can create a Redis Enterprise Cluster. Apply the following YAML to do so:
apiVersion: app.redislabs.com/v1alpha1 kind: RedisEnterpriseCluster metadata: name: redis-enterprise spec: nodes: 3
Save this content to a
rec.yaml
file, then apply the configuration:oc apply -f rec.yaml
-
Create a database
Create a Redis database using the
RedisEnterpriseDatabase
custom resource:apiVersion: app.redislabs.com/v1alpha1 kind: RedisEnterpriseDatabase metadata: name: sample-db spec: memory: 100MB
Save it as
redb.yaml
and run:oc apply -f redb.yaml
This process bootstraps a three-node Redis Enterprise cluster using the Operator. It also creates a sample database. You can interact with this database using a Redis client after retrieving the service details with oc get svc
.
Please note that the above are generic examples. You need to adjust these according to your specific requirements and OpenShift setup.
