Redis cluster (with KeyDB)

In this example, we'll deploy KeyDB Cluster and Redis Insight.
We'll also add a load balancer (HAProxy) to distribute traffic between both KeyDB. Services will be able to connect to this load balancer, which will be highly available.

1. Create KeyDB cluster + Redis Insight

Remember to fill in the “username” and “hashed_password” variables below:.
    environmentVariables:
      - key: USERNAME
        value: ""
      - key: HASHED_PASSWORD
        value: ""
        isSensitive: true

To generate HASHED_PASSWORD variable:

openssl passwd -6 superadminpassword
