VPA release 0.14.0

[kgolab]

Following instructions in
RELEASE.md.

I'm planning to do the release now, as asked by jbartosik@. It's been a while since K8s 1.27 was releases and IIUC we wanted to release a new minor VPA version around new K8s minor release.

I can also see that golang version has been bumped a few times to address vulnerabilities so I guess it's good to prepare a release for that reason as well.

I don't see any pending PRs which should block the release. In case I missed something, I will simply redo the process.

[kgolab]

The instructions say:

Update VPA version const
[ ] Wait for all VPA changes that will be in the release to merge.
[ ] Wait for [the end to end tests](https://k8s-testgrid.appspot.com/sig-autoscaling-vpa) to run with all VPA changes included.
[ ] Make sure the end to end VPA tests are green.

I can see the tests being green here https://k8s-testgrid.appspot.com/sig-autoscaling-vpa#Summary (there's a single flake from actuation suite) but it's really hard to verify what exactly was built.

The only thing I'm sure is that we're using golang 1.20.5 which means that #5434 was already included. Luckily this is the last merged PR so it seems we're good to go further.

I'll try to see if we can improve (or simply document) matching a test run with the latest included commit.

I updated version const and created a new release branch.

However I ran into trouble during Build and stage images step.
Notice amd64 being built twice (via usual go build plus via docker buildx), resulting in an error later:

The same double build is visible for all architectures but the push error is only logged for amd64 (maybe it aborts other pushes).

Investigating...

[kgolab]

@voelzmo , are there any special requirements to build the release after your #5746?

It seems that the previous release @jbartosik did was prior to this change.
I'm trying to build the next one but I ran into errors as shown in the previous comment. Hopefully you can help here :-)

[voelzmo]

Ah I think the problem is that I didn't specify a builder explicitly in the Makefile and therefore it is using the one you currently have: docker-container, which needs an output specified. (see context in the official docs about builders) On my machine, I'm using the standard docker builder, which doesn't have the option to specify and output. Here's how the whole things looks for me (when using dockerhub as a registry)

Full in-docker release vpa-recommender:v0.99.1-dev completed

I guess the fix is to include specification (and deletion) of a builder in the Makefile, to ensure that this is self-contained and not polluted by the env.

[voelzmo]

@kgolab uploaded a PR to fix this at #5867

[kgolab]

Images were built successfully, thanks @voelzmo for the docker fix :-)

One note: during the build my machine ran out of disk so I needed to rerun the whole process after creating more space.

Tests passed:

Ran 5 of 304 Specs in 2224.103 seconds
SUCCESS! -- 5 Passed | 0 Failed | 0 Pending | 299 Skipped
--- PASS: TestE2E (2224.11s)

[kgolab]

Note: I tagged the commit fixing docker set-up (cd5ed0b), not version bump (3221336) as the release process states.

The rationale was simple: if someone would like to rebuild the release for whatever reason, this makes it possible.

Release is published: https://github.com/kubernetes/autoscaler/releases/tag/vertical-pod-autoscaler-0.14.0

The rationale was simple: if someone would like to rebuild the release for whatever reason, this makes it possible.

Seems like people expect the tag to be on a different commit: We didn't include 96cdd88 and therefore the vertical-pod-autoscaler-v0.14.0 tag provides deployment yaml files referencing v0.13.0
