How to install Redis on OpenShift

In this post, we will see how to install Redis on OpenShift. To install Redis on OpenShift, we can use the official Red Hat Universal Base Image (UBI) for Redis. Here’s a step-by-step guide to help you install Redis on OpenShift:.

Step 1: Log in to OpenShift

Make sure you are logged in to your OpenShift cluster using the oc command-line tool.

oc login <your-cluster-url>

Replace <your-cluster-url> with the URL of your OpenShift cluster.

Step 2: Create a new project (optional)

You can create a new project to keep your Redis deployment isolated.

oc new-project my-redis-project

Replace my-redis-project with your desired project name.

Step 3: Deploy Redis using a Redis image

You can deploy Redis using the official Redis image from the Red Hat Universal Base Image (UBI). Create a new Redis deployment configuration.

oc new-app redis:latest

This command uses the latest version of the Redis image available. You can specify a particular version if needed.

Step 4: Expose Redis service (optional)

Expose the Redis service to make it accessible from outside the OpenShift cluster. This step is optional if you only need internal access.

oc expose service redis

Step 5: Verify Redis installation

You can verify that Redis is installed and running by accessing the Redis pod and running a Redis command.

# Get the name of the Redis pod
REDIS_POD=$(oc get pods -l app=redis -o jsonpath='{.items[0]}')

# Connect to the Redis pod
oc rsh $REDIS_POD

# Run a Redis command to check the server status
redis-cli ping

If Redis is installed and running, the output should be:


Step 6: Clean up (optional)

If you created a new project in Step 2 and want to clean up, you can delete the project.

oc delete project my-redis-project

Replace my-redis-project with the actual project name you used.

This guide assumes that you have the necessary permissions to create projects and deploy applications on your OpenShift cluster. If you encounter any issues, you may need to contact your OpenShift administrator for assistance.
