# Release Process
|
|
|
|
The Kargo Project is released on an as-needed basis. The process is as follows:
|
|
|
|
1. An issue is proposing a new release with a changelog since the last release
|
|
2. At least on of the [OWNERS](OWNERS) must LGTM this release
|
|
3. An OWNER runs `git tag -s $VERSION` and inserts the changelog and pushes the tag with `git push $VERSION`
|
|
4. The release issue is closed
|
|
5. An announcement email is sent to `kubernetes-dev@googlegroups.com` with the subject `[ANNOUNCE] kargo $VERSION is released`
|
|
|
|
## Major/minor releases, merge freezes and milestones
|
|
|
|
* Kargo does not maintain stable branches for releases. Releases are tags, not
|
|
branches, and there are no backports. Therefore, there is no need for merge
|
|
freezes as well.
|
|
|
|
* Fixes for major releases (vX.x.0) and minor releases (vX.Y.x) are delivered
|
|
via maintenance releases (vX.Y.Z) and assigned to the corresponding open
|
|
milestone (vX.Y). That milestone remains open for the major/minor releases
|
|
support lifetime, which ends once the milestone closed. Then only a next major
|
|
or minor release can be done.
|
|
|
|
* Kargo major and minor releases are bound to the given ``kube_version`` major/minor
|
|
version numbers and other components' arbitrary versions, like etcd or network plugins.
|
|
Older or newer versions are not supported and not tested for the given release.
|
|
|
|
* There is no unstable releases and no APIs, thus Kargo doesn't follow
|
|
[semver](http://semver.org/). Every version describes only a stable release.
|
|
Breaking changes, if any introduced by changed defaults or non-contrib ansible roles'
|
|
playbooks, shall be described in the release notes. Other breaking changes, if any in
|
|
the contributed addons or bound versions of Kubernetes and other components, are
|
|
considered out of Kargo scope and are up to the components' teams to deal with and
|
|
document.
|
|
|
|
* Minor releases can change components' versions, but not the major ``kube_version``.
|
|
Greater ``kube_version`` requires a new major or minor release. For example, if Kargo v2.0.0
|
|
is bound to ``kube_version: 1.4.x``, ``calico_version: 0.22.0``, ``etcd_version: v3.0.6``,
|
|
then Kargo v2.1.0 may be bound to only minor changes to ``kube_version``, like v1.5.1
|
|
and *any* changes to other components, like etcd v4, or calico 1.2.3.
|
|
And Kargo v3.x.x shall be bound to ``kube_version: 2.x.x`` respectively.
