Developer News

Deprecated registry k8s.gcr.io has been redirected to registry.k8s.io. This may cause issues with some builds and/or deployments, so check yours for image pull errors. Please update your infrastructure and code to use the new registry, as much as you can.

The resource.k8s.io/v1alpha1 API types for dynamic resource allocation (ResourceClaim, ResourceClaimTemplate, ResourceClass, PodScheduling) have been removed and replaced with a resource.k8s.io/v1alpha2. As this is still an alpha feature, no upgrade path is provided and any existing objects must be removed before upgrade or you risk database sadness. As part of this bump, some incompatible changes have been made. If you’ve been trying out this alpha feature, please make sure to check out the changes and take appropriate action in your development/testing environments.

Release Schedule

Developer News

Lots of important and urgent news this week.

In one week, deprecated registry k8s.gcr.io will be automatically redirected to registry.k8s.io. This may break some existing Kubernetes setups, especially those running older versions in secure or gapped environments. Make sure that registry.k8s.io is on your allowlist for image pulls. This measure is only temporary; long-term, you still need to update your installations and components to use registry.k8s.io.

We’ve had to stop releasing Kubernetes for 32-bit Linux/ARM because Golang isn’t consistently working on it. If 32-bit ARM as a platform matters to you, consider getting involved in the Go project to stabilize support.

Developer News

Reminder: k8s.gcr.io will be frozen on April 3rd. You need to update all components to target registry.k8s.io. Also, update your production clusters to pull from registry.k8s.io; this should work with both (updated) containerd and CRI-O now.

The Contributor Summit is looking for session suggestions. These can be sessions you’ll lead, or sessions you want to attend – please suggest!

Kubernetes has been invited to participate in the 2023 OpenInfra Project Team Gathering. If you’re interested – especially if you were going anyway – please tell Kendall Nelson. We particularly want folks who work on the OpenStack Cloud Provider.

Developer News

Image Registry Migration: the old signing key, on packages.cloud.google.com, has stopped working. You need to use the new key on dl.k8s.io. The community-images krew plugin will help you identify any remaining references to the old registry on your cluster. It’s not just users who need to update; 60 of our project’s own repositories still refer to the old registry. Please check those resources and update as soon as you can.

Registration is open for the Amsterdam contributor summit. If you are eligible and attending, please register as soon as you can, so that the summit team can get a headcount and you can get a hoodie.

Aravindh Puthiyaparambil has been nominated as co-chair of SIG-Windows. Casey Davenport is stepping down from SIG-Network, and has nominated Shane Utt to take his place.

Developer News

The changes to the auto-close workflow have been merged.

The commit bot will stop suggesting /assign commands as part of its response to opening a new PR, to encourage authors to seek reviewers and not go straight to approvers. Leads and owners should boost this by recruiting/mentoring reviewers. If your SIG or project needs any help with this, please reach out to ContribEx.

Do we need to support 32-bit ARM? Speak up if it’s something you use.

Developer News

The old image registry, k8s.gcr.io, will stop taking updates on April 3. As a contributor, you need to make sure that you’re pushing builds to registry.k8s.io and that any components that you call are pulling from the new registry. Users should also check any of their CI that pulls images.

The Kubernetes Java client is affected by CVE-2022-1471, a remote code execution. Update your Java client ASAP.

• Discussed the state of statefulness including the status of features like Taints, PDB, QoS, and slices
• Went over the limitations of kubectl apply and how we might solve them
• SIG-Network wants to run kubemark tests on networking components at large scale
• Apparently Kubernetes API user experience is a mess
• Most people don’t understand the real Pod Lifecycle, and who can blame them?
• Now that Dockershim is gone, it’s time to completely overhaul how CRI works

Two security reports this week: CVE-2022-3172, which allows aggregated API servers to misdirect traffic and steal credentials, and CVE-2021-25749, which can let users deploy Windows container workloads as Administrator. Both issues are fixed in the latest patch releases. Note that the patch for CVE-2022-3172 blocks all 300ish responses, so test after upgrading and be prepared to set --aggregator-reject-forwarding-redirect if your API server uses redirects.
