Image creation
Review the most notable changes to image creation between RHEL 9 and RHEL 10.
- The
image-buildercommand-line interface (CLI) tool is now generally available. - The web console provides an integrated workflow to build
bootc-compatible container images from local container environments. - Output formats and target identifiers are aligned across both the web console and CLI, for example,
awsfor Amazon Machine Images andguest-imagefor QEMU Copy-On-Write 2qcow2. - Includes automated system registration during first boot, support for user-specified custom base images, and safety warnings when building image-mode assets without a default user account.
Key highlights for RHEL installer:
- The newly created users will have administrative privileges by default, unless you deselect the option.
- You can now set the required time zone by using new options instead of the time zone map.
- The remote desktop protocol (RDP) for graphical remote access replaces VNC.
Key highlights for RHEL image builder:
- General availability of the image-builder CLI: The
image-buildercommand-line interface (CLI) tool is now generally available for building operating system artifacts and image-mode assets directly from the terminal. - Streamlined web console image mode: Build
bootc-compatible images from local containers directly incockpit-image-builder. - Unified format names across the CLI and user interface (UI), such as
awsfor Amazon Machine Images (AMIs) andguest-imagefor QEMU Copy-On-Write 2 (qcow2). - Expanded image mode support: Added automated system registration during first boot, support for custom base images, and missing default-user warnings.
