Install your InfluxDB Clustered license

Install your InfluxDB Clustered license in your cluster to authorize the use of the InfluxDB Clustered software.

Install your InfluxDB license

1. If you haven’t already, request an InfluxDB Clustered license.

2. InfluxData provides you with a license.yml file that encapsulates your license token as a custom Kubernetes resource.

3. Use kubectl to apply and create the License resource in your InfluxDB namespace:

   kubectl apply --filename license.yml --namespace influxdb
   

InfluxDB Clustered detects the License resource and extracts the credentials into a secret required by InfluxDB Clustered Kubernetes pods. Pods validate the license secret both at startup and periodically (roughly once per hour) while running.

Upgrade from a non-licensed release

If you are currently using a non-licensed preview release of InfluxDB Clustered and want to upgrade to a licensed release, do the following:

1. Install an InfluxDB license

2. If you use the AppInstance resource configuration to configure your cluster, in your myinfluxdb.yml, update the package version defined in spec.package.image to use a licensed release.

   If using the InfluxDB Clustered Helm chart, update the image.tag property in your values.yamlto use a licensed release.

   Upgrade to checkpoint releases first

   When upgrading InfluxDB Clustered, always upgrade to each checkpoint release first, before proceeding to newer versions. Upgrading past a checkpoint release without first upgrading to it may result in corrupt or lost data.

apiVersion: kubecfg.dev/v1alpha1
kind: AppInstance
# ...
spec:
  package:
    # ...
    image: us-docker.pkg.dev/influxdb2-artifacts/clustered/influxdb:
PACKAGE_VERSION

# values.yaml

image:
  tag: 
PACKAGE_VERSION

Replace PACKAGE_VERSION with the version number to upgrade to.

Verify your license

After you have activated your license, use the following signals to verify the license is active and functioning.

Verify the Secret exists

Run the following command to verify that the licensing activation created a iox-license secret:

kubectl get secret iox-license --namespace influxdb

If the secret doesn’t exist, view license-controller logs for more information or errors.

View license controller logs

The license controller component creates a Secret named iox-license from your License. To view license controller logs for troubleshooting, run the following command:

kubectl logs deployment/license-controller --namespace influxdb
