An issue exists with the factory-default version of Universal Compute Platform. When unpacking your system, you may see an "Activation Required" message along with Locking ID. The message instructs you to select your license PKI file for activation. Ignore this message as your system will not lock up. This issue has been fixed with newer versions of Universal Compute Platform.
The ExtremeCloud Edge platform leverages Kubernetes at its core for managing the orchestration of applications,whether in a single node or multi-node cluster. When Kubernetes is installed or upgraded, the framework automatically self-generates an operational certificate. This certificate is valid for one calendar year following the installation date. You must check certificate validity periodically to ensure that it does not expire. Certificate expiratation leads to the halting of the Kubernetes platform and the functionality that the installed applications provide.
Automated monitoring and refreshing of these certificates is a task in progress that will be addressed in a future release.
In the interim, for systems that have been installed and running for a while, we advise you to validate the state of certificates and their expiration. If any certificates are expiring within 90 days, complete the following procedure to refresh them. For multi-node cluster installations, complete the procedure on each member node of the cluster.
Refresh Kubernetes Certificates
For each cluster node, open a terminal connection to the node and run the following shell commands:
Change the directory by running the command cd ~/.kube.
Run the command kubeadm certs check-expiration.
The command output displays the list of certificates and certificate authorites, along with expiration dates and the number of days before expiration (in the RESIDUAL TIME field).
If any certificates show a RESIDUAL TIME that is less than 90 days, renew all certificates by running the command kubeadm certs renew all.
After renewing certificates, All certificates should show 364 days remaining.
