This article teaches how to use the Secrets Store CSI driver to mount secrets to Kubernetes pods and covers how to configure and simulate the CSI driver failover feature. More: https://lnkd.in/dv7CbAwk

If Kubernetes autoscaling complexity makes your head spin, join our webinar in ~1 hour! You’ll walk away with a deep understanding of the various autoscaling dimensions and the open-source projects that can plug in to meet specific use cases with technical guidance from Rodrigo Bersa, John Platt and Erwin Daria. They'll give you the low down on these key use cases: ⚖ Scaling on CPU utilization with the HPA ⚖ Scaling to zero using KEDA ⚖ Ongoing cluster consolidation using Karpenter ⚖ Introducing spot instances to your cluster ⚖ Automatically rightsizing containers Link in chat to sign up!

Do not run multiple ps inside your docker container Do not treat your container like a VM Either use docker-compose or an orchestrator to run multiple containers Docker containers are not VM's and shouldnt be used like one

Kubernetes 1.30: Preventing unauthorized volume mode conversion moves to GA @matthias / #Kubernetes #kubernetes-users - With the release of Kubernetes 1.30, the feature to prevent the modification of the volume mode of a PersistentVolumeClaim that was created from an existing VolumeSnapshot in a Kubernetes cluster, has moved to GA! The problem The Volume Mode of a PersistentVolumeClaim refers to whether the underlying volume on the storage device is formatted into a filesystem or presented as a raw block https://lnkd.in/e8Re8uxV

Persistent storage can be complicated. In this first post in an ongoing series we look at persistent storage in Docker, specifically the difference between bind mounts and named volumes. https://bit.ly/4c5Do9W

This article discusses configuring Kubernetes to store containers on a separate filesystem to prevent disk space from running out. It also covers node pressure eviction and future work on improving ephemeral storage reporting. More: https://lnkd.in/gk7p2rVr

Most applications running in containers output logs to `stdout`/`stderr`. In Kubernetes, `terminationMessagePolicy` configures how these termination logs are captured. Learn how they work in this article. More: https://lnkd.in/gGcU2xSk

This article presents a proof of concept for synchronizing eBPF map states across a multi-node Kubernetes cluster, which ensures high availability and avoids single points of failure in stateful applications. More: https://lnkd.in/g7AxGZy5
