In the coming months, the Podman container runtime will be upgraded from v3 to v4. This is a major release [1] that introduces backward incompatible changes to configuration files and APIs. The full release notes for Podman v4 are available at [2]. Here is a brief summary of how this will impact Fedora CoreOS nodes: - Existing containers will be preserved without any change required. - Compatibility for the Docker API is fully preserved. - Users of the Podman remote API will need matching server/client versions. - Rollbacks to a version with Podman v3.x will require manual action. - Only new installations will use the new network stack by default. For more details, see the Major Changes page in the Fedora CoreOS documentation [3]. This change will be rolled out together with the rebase to Fedora 36: - the `next` rebase is targeted for 2022-03-15 - the `testing` rebase is targeted for 2022-04-19 - the `stable` stream will follow `testing` as usual Thanks, Jonathan Lebon, for the Fedora CoreOS team [1] https://podman.io/releases/2022/02/22/podman-release-v4.0.0.html [2] https://github.com/containers/podman/releases/tag/v4.0.0 [3] https://docs.fedoraproject.org/en-US/fedora-coreos/major-changes/#_podman_v4_0 _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
