All public and private clusters with egress lockdown get their Red Hat container images from a registery that is located in the local region of the cluster instead of gathering these images from various endpoints and registeries on the Internet. You can create a fully operational cluster that does not require a public egress by configuring a virtual private cloud (VPC) and using the `--properties zero_egress:true` flag when creating your cluster.

Original: Creating a {product-title} cluster with egress lockdown provides a way to enhance your cluster's stability and security by allowing your cluster to use the image registry in the local region if the cluster cannot access the Internet. Your cluster will try to pull the images from Quay, but when they aren't reached, it will instead pull the images from the image registry in the local region.

Original: = Backing up etcd
// This assembly will contain modules to provide information about backing up and restoring etcd.
Revised: Back up the etcd data for your cluster regularly and store it in a secure location, ideally outside the {product-title} environment.

[IMPORTANT]
====
Do not take an etcd backup before the first certificate rotation completes, which occurs 24 hours after installation, otherwise the backup will contain expired certificates. It is also recommended to take etcd backups during non-peak usage hours because the etcd snapshot has a high I/O cost.

Original: The Machine Config Operator (MCO) uses a boot image to start a {op-system-first} node. By default, {product-title} does not manage the boot image.
This means that the boot image in your cluster is not updated along with your cluster. For example, if your cluster was originally created with {product-title} 4.12, the boot image that the cluster uses to create nodes is the same 4.12 version, even if your cluster is at a later version. If the cluster is later upgraded to 4.13 or later, new nodes continue to scale with the same 4.12 image.
This process could cause the following issues:
To avoid these issues, you can configure your cluster to update the boot image whenever you update your cluster. By modifying the `MachineConfiguration` object, you can enable this feature. Currently, the ability to update the boot image is available for only Google Cloud Platform (GCP) and Amazon Web Services (AWS) clusters. It is not supported for clusters managed by the {cluster-capi-operator}.
If you are not using the default user data secret, named `worker-user-data`, in your machine set, or you have modified the `worker-user-data` secret, you should not use managed boot image updates. This is because the Machine Config Operator (MCO) updates the machine set to use a managed version of the secret. By using the managed boot images feature, you are giving up the capability to customize the secret stored in the machine set object.
