Kubernetes' Default CoreDNS Configuration Is *Insecure

Kubernetes의 기본 CoreDNS 설정에 포함된 'pods insecure' 옵션은 DNS A 레코드를 검증 없이 반환하여 보안 취약점을 유발한다. 이로 인해 네트워크 정책 도구인 Cilium과 결합 시, 악의적인 사용자가 외부 IP를 내부 도메인으로 위장해 정책을 우회할 수 있다. 해당 문제는 CoreDNS와 Cilium 프로젝트에 보고되어 문서 개선이 이루어졌으며, Kubernetes 배포판에서 기본 설정을 'verified'로 변경해 보안을 강화할 필요가 있다.

Kubernetes' Default CoreDNS Configuration is *insecure*

Discover how a default CoreDNS configuration left over for backward compatibility can allow attackers to completely bypass Cilium network policies.

#kubernetes 1.36 just revolutionized #container volumes by adding support to use a standard #docker or #oci image as readonly volume in a pod, allowing to decouple a runtime image from the assets. We can now update a #nginx image without rebuilding the static #website artifact in #pipeline. There are also advantages to storage usage and data deduplication!

Static web hosting on Kubernetes with OCI images as volumes - kowalski7cc

Taking advantage new Kubernetes features to simplify static site deployment, and not only, by using OCI images as container volumes along with vendor runtime images.

I will say, there are a lot of things about kubernetes that are a total pain in the ass, but the ability to just write a few* lines of YAML and get a fully working application just like that is pretty freaking magical.

#kubernetes #k8s

Kubernetes HA question.

I can do multi replica Deployment/StatefulSet and a Service will load balance between them, but what about if I need a hot spare?

Best I've come up with so far is 2 different Deployments with different labels and switching the Service selector between the labels.

Anything else K8s native that would solve the problem (assuming external trigger for fail over)

Our Co-founder, @valyala , shared great insights in his talk “Strategies for Efficient #LogManagement in Large-Scale #Kubernetes Clusters”.

Large Kubernetes clusters can generate significant volumes of logs, especially when housing thousands of running pods.
