* Required only if the application uses the [Replicated private registry](/vendor/private-images-replicated).

:::note
If you monitor the outbound traffic attempts made by Embedded Cluster, you might see an attempted call to `updates.k0sproject.io` approximately every 30 minutes. These calls are made by a feature of the upstream k0s project called `update-prober`, which checks for k0s updates. Embedded Cluster does not use the `update-prober` feature and blocking it in your firewall rules will not affect Replicated product functionality.
