第2章 Mirroring container images for disconnected installations
You can use a custom container registry when you deploy MicroShift in a disconnected network. Running your cluster in a restricted network without direct internet connectivity is possible by installing the cluster from a mirrored set of container images in a private registry.

Using a custom air-gapped container registry, or mirror, is necessary with certain user environments and workload requirements. Mirroring allows for the transfer of container images and updates to air-gapped environments where they can be installed on a MicroShift instance.
To create an air-gapped mirror registry for MicroShift containers, you must complete the following steps:
- Get the container image list to be mirrored.
- Configure the mirroring prerequisites.
- Download images on a host with internet access.
- Copy the downloaded image directory to an air-gapped site.
- Upload images to a mirror registry in an air-gapped site.
- Configure your MicroShift hosts to use the mirror registry.
