To expose Redis in Kubernetes, you need to create a Service resource. A Service is an abstraction for exposing applications running on a set of Pods. You can use the Redis Helm Chart for easier deployment and management.
Here's a step-by-step guide:
Install Helm: If you haven't already, install Helm - a package manager for Kubernetes. Follow the official installation guide.
Add Bitnami Repository: Add the Bitnami repository to your Helm CLI:
In this command,
my-redis is the release name. You can replace it with your desired name. The flag
--set service.type=LoadBalancer configures the Redis service to be exposed as a LoadBalancer type. This automatically provisions an external IP for accessing Redis.
Wait a few minutes until the external IP is allocated. Check the status with the following command:
Replace "my-redis" with the release name you used earlier. Once the IP address is available, you can use it to access your Redis instance.
To retrieve the Redis password, execute:
Now you can access your Redis instance using the external IP and password.
Important: Exposing Redis to a public IP without any security measures is not recommended. Consider using Network Policies, authentication mechanisms, or creating private clusters for production scenarios.
