Your installation is either missing a license certificate completely (e.g. new developer install), or the certificate has expired.

The actual license files are provided to you as either an e-mail or a download from the Lifecycle Manager tool. For a pure developer install you can use an activation code instead.

If running in a generic kubernetes environment

Remove old license (if installed):

                # kubectl delete secret commerce7-identity

Install new license:

                # kubectl create secret tls commerce7-identity --cert=<certificate> --key=<key>

If running in a developer environment

Activate license using activation code, from within the container

                % /data/html/system/bin/c7adm activate <activation code>
