Redis

Usage example

Example 
apiVersion: aiven.io/v1alpha1
kind: Redis
metadata:
  name: k8s-redis
spec:
  authSecretRef:
    name: aiven-token
    key: token

  connInfoSecretTarget:
    name: redis-token
    prefix: MY_SECRET_PREFIX_
    annotations:
      foo: bar
    labels:
      baz: egg

  project: my-aiven-project
  cloudName: google-europe-west1
  plan: startup-4

  maintenanceWindowDow: friday
  maintenanceWindowTime: 23:00:00

  userConfig:
    redis_maxmemory_policy: allkeys-random

Info

To create this resource, a Secret containing Aiven token must be created first.

Apply the resource with:

kubectl apply -f example.yaml

Verify the newly created Redis:

kubectl get redis k8s-redis

The output is similar to the following: 

Name         Project             Region                 Plan         State      
k8s-redis    my-aiven-project    google-europe-west1    startup-4    RUNNING

To view the details of the Secret, use the following command: 

kubectl describe secret redis-token

You can use the jq to quickly decode the Secret:

kubectl get secret redis-token -o json | jq '.data | map_values(@base64d)'

The output is similar to the following:

{
    "REDIS_HOST": "<secret>",
    "REDIS_PORT": "<secret>",
    "REDIS_USER": "<secret>",
    "REDIS_PASSWORD": "<secret>",
}
