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
