Chapter 6. Configuring Redis storage for rate limiting

Procedure

1. Set the following environment variable to your shared Redis-based instance URL:

   export REDIS_URL=rediss://user:xxxxxx@some-redis.com:10340

   Ensure that you include the appropriate URI scheme for your environment:

   • Secure Redis: rediss://
   • Standard Redis: redis://

2. Create a Secret resource for your Redis URL as follows:

   kubectl -n kuadrant-system create secret generic redis-config \
     --from-literal=URL=$REDIS_URL

3. Update your Limitador custom resource to use the secret that you created as follows:

   kubectl patch limitador limitador --type=merge -n kuadrant-system -p '
   spec:
     storage:
       redis:
         configSecretRef:
           name: redis-config
   '
