## Cadence
|
|
|
|
|
|
2021-06-03 11:59:05 +00:00
|
|
|
Our typical patch release cadence is monthly. It is
|
2021-05-06 23:46:08 +00:00
|
|
|
commonly a bit faster (1 to 2 weeks) for the earliest patch releases
|
2021-06-03 11:59:05 +00:00
|
|
|
after a 1.X minor release. Critical bug fixes may cause a more
|
|
|
|
|
immediate release outside of the normal cadence. We also aim to not make
|
2021-05-06 23:46:08 +00:00
|
|
|
releases during major holiday periods.
|
|
|
|
|
|
|
|
|
|
## Contact
|
|
|
|
|
|
|
|
|
|
See the [Release Managers page][release-managers] for full contact details on the Patch Release Team.
|
|
|
|
|
|
|
|
|
|
Please give us a business day to respond - we may be in a different timezone!
|
|

|
|
|
In between releases the team is looking at incoming cherry pick
|
2021-06-03 11:59:05 +00:00
|
|
|
requests on a weekly basis. The team will get in touch with
|
2021-05-06 23:46:08 +00:00
|
|
|
submitters via GitHub PR, SIG channels in Slack, and direct messages
|
|
|
|
|
in Slack and [email](mailto:release-managers-private@kubernetes.io)
|
|
|
|
|
if there are questions on the PR.
|
|
|
|

|
|
|
## Cherry picks
|
2021-05-06 23:46:08 +00:00
|
|
|
|
2021-05-15 19:49:41 +00:00
|
|
|
Please follow the [cherry pick process][cherry-picks].
|
2021-05-06 23:46:08 +00:00
|
|
|
|
2021-05-15 19:49:41 +00:00
|
|
|
Cherry picks must be merge-ready in GitHub with proper labels (e.g.,
|
|
|
|
|
`approved`, `lgtm`, `release-note`) and passing CI tests ahead of the
|
2021-06-03 11:59:05 +00:00
|
|
|
cherry pick deadline. This is typically two days before the target
|
|
|
|
|
release, but may be more. Earlier PR readiness is better, as we
|
2021-05-15 19:49:41 +00:00
|
|
|
need time to get CI signal after merging your cherry picks ahead
|
2021-05-06 23:46:08 +00:00
|
|
|
of the actual release.
|
|
|
|
|
|
2021-05-15 19:49:41 +00:00
|
|
|
Cherry pick PRs which miss merge criteria will be carried over and tracked
|
2021-05-06 23:46:08 +00:00
|
|
|
for the next patch release.
|
|
|
|
|
|
|
|
|
|
## Support Period
|
|
|
|
|
|
|
|
|
|
In accordance with the [yearly support KEP][yearly-support], the Kubernetes
|
|
|
|
|
Community will support active patch release series for a period of roughly
|
|
|
|
|
fourteen (14) months.
|
|
|
|
|
|
|
|
|
|
The first twelve months of this timeframe will be considered the standard
|
|
|
|
|
period.
|
|
|
|
|
|
|
|
|
|
Towards the end of the twelve month, the following will happen:
|
|
|
|
|
|
|
|
|
|
- [Release Managers][release-managers] will cut a release
|
|
|
|
|
- The patch release series will enter maintenance mode
|
|
|
|
|
|
|
|
|
|
During the two-month maintenance mode period, Release Managers may cut
|
|
|
|
|
additional maintenance releases to resolve:
|
|
|
|
|
|
2021-08-23 11:24:01 +00:00
|
|
|
- CVEs (under the advisement of the Security Response Committee)
|
2021-05-06 23:46:08 +00:00
|
|
|
- dependency issues (including base image updates)
|
|
|
|
|
- critical core component issues
|
|
|
|
|
|
|
|
|
|
At the end of the two-month maintenance mode period, the patch release series
|
|
|
|
|
will be considered EOL (end of life) and cherry picks to the associated branch
|
|
|
|
|
are to be closed soon afterwards.
|
|
|
|
|
|
|
|
|
|
Note that the 28th of the month was chosen for maintenance mode and EOL target
|
|
|
|
|
dates for simplicity (every month has it).
|
|
|
|
|
|
|
|
|
|
## Upcoming Monthly Releases
|
|
|
|
|
|
|
|
|
|
Timelines may vary with the severity of bug fixes, but for easier planning we
|
2021-06-03 11:59:05 +00:00
|
|
|
will target the following monthly release points. Unplanned, critical
|
2021-05-06 23:46:08 +00:00
|
|
|
releases may also occur in between these.
