You can apply your product key at any time within the product UI or during an install or upgrade process. More details on both options are provided below.
To apply your license key within the Kubecost UI, visit the Overview page and then select UPGRADE in the page header. Next, select ADD KEY in the dialog menu shown below. You can then supply your Kubecost provided license key in the input box that is now visible.
Many Kubecost product configuration options can be specified at install-time, including your product key.
This specific parameter can be configured under kubecostProductConfigs.productKey.key in your values.yaml.
Note: you must also set kubecostProductConfigs.productKey.enabled to true when using this option.
