Prerequisites
Basic Authentication
Follow these steps if your Redis server requires user and password authentication
1.- Create a user and password in your Redis instance for the exporter.
ACL SETUSER USERNAME +client +ping +info +config|get +cluster|info +slowlog +latency +memory +select +get +scan +xinfo +type +pfcount +strlen +llen +scard +zcard +hlen +xlen +eval allkeys on >PASSWORD
Replace USERNAME and PASSWORD with yours for the Redis instance.
2.- Create a secret with the user and password for the exporter. Keep the following in mind:
- It has to be in the same namespace where the exporter will be deployed.
- Use the same user name and password that you used for the api in the previous step.
- You can change the name of the secret. If you do it, you will need to select it in the next steps of the integration.
kubectl create secret -n Your-Application-Namespace generic redis-exporter-auth \
--from-literal=user=USER \
--from-literal=password=PASSWORD
Replace USER and PASSWORD with yours for the Redis instance.
