Learned it the hard way: don't use Cilium's default Pod CIDR, with Isala Piyarisi

https://ku.bz/kJjXQlmTw

This episode examines how a default configuration in Cilium CNI led to silent packet drops in production after 8 months of stable operations.

Isala Piyarisi, Senior Software Engineer at WSO2, shares how his team discovered that Cilium's default Pod CIDR (10.0.0.0/8) was conflicting with their Azure Firewall subnet assignments, causing traffic disruptions in their staging environment.

You will learn:

How Cilium's default CIDR allocation can create routing conflicts with existing infrastructure

A methodical process for debugging network issues using packet tracing, routing table analysis, and firewall logs

The procedure for safely changing Pod CIDR ranges in production clusters

Developer News

Lucy Sweet and Tim Hockin would like to hear your answers to some (not so serious) questions about Kubernetes. Submit your answers here!

CNCF’s Mentoring team is looking for Google Summer of Code mentorship tasks for GSOC 2025. If your SIG has mentors and wants to participate, please submit a PR to the 2025 plan.

Release Schedule

Next Deadline: Placeholder PRs for Docs, February 27

Enhancements freeze was last week and we have a total of 76 KEPs tracked for v1.33 after the freeze! Out of these, 30 are KEPs in alpha, 22 graduating to beta, 22 graduating to GA and 2 are deprecation/removal KEPs.

The next deadline is the Docs placeholder PRs deadline, which is on February 27th. If you have your KEP(s) tracked for the release, follow the steps here to open a placeholder PR against the dev-1.33 branch in the k/website repo soon.

KEP of the Week

KEP 3257: Cluster Trust Bundles

This KEP introduces ClusterTrustBundle, a cluster-scoped resource for certificate signers to share trust anchors with workloads, along with a clusterTrustBundle kubelet projected volume source for filesystem-based access. A default ClusterTrustBundle with the kubernetes.io/kube-apiserver-serving signer is also introduced, potentially replacing the current kube-root-ca.crt ConfigMaps.

Other Merges

kube-proxy adds new metric to track entries deleted in conntrack reconciliation

kube-proxy adds new metric to track conntrack reconciliation latency

Rewrites to network-related e2e tests to use Deployments instead of ReplicationControllers

E2E tests added for HonorPVReclaimPolicy

apiserver /flagz endpoint fixed to respond with actual parsed flags

golangci-lint removed “strict” checking

Promotions

NFTablesProxyMode to GA

Shoutouts

aojea: Shoutout to Elizabeth Martin Campos for relentless digging through the legacy e2e code and fixing an incorrect assumption that was buried there

Dipesh Rawat, the v1.33 Enhancements Lead gives big shoutouts to the v1.33 Enhancement shadows: @Arka, @eunji, @Faeka Ansari, @Jenny Shu and @lzung (extra kudos to the first-time shadows on the team :clap:) for all their hard work tracking over 90+ KEPs for the enhancement freeze!

Simplifying Kubernetes deployments with a unified Helm chart, with Calin Florescu

https://ku.bz/mcPtH5395

Managing microservices in Kubernetes at scale often leads to inconsistent deployments and maintenance overhead. This episode explores a practical solution that standardizes service deployments while maintaining team autonomy.

Calin Florescu discusses how a unified Helm chart approach can help platform teams support multiple development teams efficiently while maintaining consistent standards across services.

You will learn:

Why inconsistent Helm chart configurations across teams create maintenance challenges and slow down deployments

How to implement a unified Helm chart that balances standardization with flexibility through override functions

How to maintain quality through automated documentation and testing with tools like Helm Docs and Helm unittest

Say Goodbye to Tedious Docker Commands: Embrace Docker to Bake Images

Building and pushing Docker container images can be tedious, especially when dealing with multiple platforms, versions, and images. This video demonstrates how to simplify this process using Docker Bake. Follow along as we set up the environment, build and push backend and frontend images manually, and then switch to Docker Bake for a more efficient workflow. Learn how to use Docker Bake's declarative approach to streamline image building and pushing, reduce errors, and save time. Perfect for developers looking to optimize their Docker workflows.
