Flussi di aggiornamento
Flussi di aggiornamento individuali
Fedora CoreOS (FCOS) offre diversi stream di aggiornamenti individuali disponibili per gli utenti finali. Essi sono:
-
stable
-
Il flusso
stable
è il più affidabile offerto, poiché le modifiche vi arrivano solo dopo aver trascorso un periodo nel flussotesting
.
-
-
testing
-
The
testing
stream represents what is coming in the nextstable
release. Content in this stream is updated regularly and offers our community an opportunity to catch breaking changes before they hit thestable
stream.
-
-
next
-
The
next
stream represents the future. It will often be used to experiment with new features and also test out rebases of our platform on top of the next major version of Fedora. The content in thenext
stream will also eventually filter down intotesting
and on tostable
.
-
When following a stream, a system is updated automatically when a new release is rolled out on that stream. While all streams of FCOS are automatically tested, it is strongly encouraged for users to devote a percentage of their FCOS deployment to running the testing
and next
streams. This ensures possible breaking changes can be caught early enough that stable
deployments experience fewer regressions.
Switching to a Different Stream
In order to switch between the different streams of Fedora CoreOS (FCOS) a user can leverage the rpm-ostree rebase
command.
It may be a good idea to backup data under |
Software updates generally follow the |
Switching between streams may introduce regressions or bugs due to skipping update barriers. If you experience a regression please attempt a rollback. |
# Stop the service that performs automatic updates
sudo systemctl stop zincati.service
# Perform the rebase to a different stream
# Supported architectures: aarch64, ppc64le, s390x, x86_64
# Available streams: "stable", "testing", and "next"
STREAM="testing"
sudo rpm-ostree rebase "ostree-remote-registry:fedora:quay.io/fedora/fedora-coreos:${STREAM}"
After inspecting the package difference the user can reboot. After boot the system will be loaded into the latest release on the new stream and will follow that stream for future updates.
