Containers
The following features, enhancements, and changes related to containers are introduced in this Oracle Linux 9 release.
Podman Updated to Version 5.4
Podman is updated to version 5.4. The components for Podman are in the
container-tools package.
The Container Tools RPM meta-package, features updates to Podman, Buildah, Skopeo,
crun, and runc tools. Updating the package pulls in the
latest versions of these subcomponents, including:
- podman-5.4
- buildah-1.39
- crun-1.21
- runc-1.2.4
- skopeo-1.18
Notably, Podman v5.4 includes various bug fixes and enhancements over the previous version. See https://github.com/containers/podman/releases for more information.
zstd:chunked Image Compression in Podman
Podman can use images compressed with the zstd:chunked format to reduce
image sizes and partial pulls, and improve efficiency in container image management. Note that
this feature is only tested for x86_64 platforms.
Customizable Healthcheck Output in Podman
You can now customize the storage of healthcheck output for individual containers in Podman, enabling more detailed debugging information to be retained as needed, and controlling healthcheck output storage for specific containers to address concerns around data sensitivity and storage optimization. This enhancement is useful for troubleshooting sporadic healthcheck failures without impacting the live service. This is a significant improvement over the previous limitations, where healthcheck output was restricted to the five most recent runs, with a character limit of 500 per run, and could only be accessed through the podman inspect command.
