# Licensing Docker Apps ## Licensing Docker apps When an app runs inside a Docker, it gives very little access to the host hardware details. Hence it is difficult to generate a quality device fingerprint. This makes node-locked licensing almost useless in case of apps running inside Docker. And if you decide to use node-locked licenses, then your customers can easily use the same license key across different Docker instances running on the same or different devices. ## Using floating licenses [Floating licenses](https://docs.cryptlex.com/floating-licenses) are the best way to license Docker applications. For apps having access to the internet, you should use hosted-floating license type and apps which have no access to the internet you should use on-premise floating license type. Also, ensure [leasing strategy](https://docs.cryptlex.com/license-management/license-templates#leasing-strategy) for the license is set to **"per-instance".** When you set the leasing strategy to **"per-instance"**, it ensures a new license activation is consumed whenever your app sends an activation request irrespective of whether the device fingerprint is the same or different. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
