Container Image Exporter
Introduction
The Container Image Exporter plugin facilitates the export of container images into tarball files and then uploads these files to cloud storage. This process simplifies the transfer of container images, particularly beneficial for air-gapped environments where external network access is restricted. By converting images to tarballs, you can easily transport them via physical drives to the isolated systems. This approach is especially valuable in scenarios where direct network-based transfers are not permitted.
Prerequisites
Before integrating the Container Image Exporter plugin, you need to properly configure your cloud storage to store the generated tarball files.
