Licensing the Anjuna Nitro Runtime

A license may have two types. The type of license is represented by the kind field in the license file. A trial-type license is used for proof-of-concept projects and trials, while a licensed-type license is used for up-and-running software that serves your development, testing, and production environments.

You cannot build or run an enclave without a license present.

For trial-type licenses, running enclaves will terminate if the license has expired. You cannot start an enclave if the license has expired.

For licensed-type licenses, running enclaves will not terminate when the license expires in order to avoid impacting your customers. New enclaves will also continue to start even if the license has expired. Use of an expired licensed-type license will produce log messages like this:

AWS Nitro licenses are valid for any version of the Anjuna Nitro Runtime, but not any other runtime platform like the Anjuna Runtime for Intel® SGX Enclaves.

Visit the Anjuna Resource Center to download your license file. Your license file is associated with your Anjuna Resource Center account.

Here is an example of a license file. If the kind type or expires date is not as expected, please contact sales@anjuna.io.

A license is activated by placing the file onto the AWS Nitro EC2 instance at the default path /opt/anjuna/license.yaml. You can use the environment variable ANJUNA_LICENSE_PATH to configure a different location for the license.

For EKS, you will need to create a Kubernetes secret for the license file. The Anjuna Nitro Webhook will mount the license file automatically to your Pod. See Licensing the Anjuna Nitro Runtime for an Anjuna Nitro Pod for details.

Upon successful activation, you will see a line similar to the following in the enclave logs:

After signing a new contract or extending an existing one, you can visit the Anjuna Resource Center to download a new license file.

The new license can be used to start new enclaves. See Use your license for details on how to do this.

You can also renew the license of a running enclave by putting the new license at the same path that you used when starting the enclave, or by updating the Kubernetes secret, which is volume mounted to the enclave Pod. The Anjuna Runtime will automatically detect the new license and extend the term.
