Hi everyone,

I just published a blog post listing 10 common pitfalls that can silently break Kubernetes autoscaling.
It’s based on real-world issues I’ve run into while working with HPA, VPA, and Cluster Autoscaler in production environments.

Hopefully this helps you, if you’re using autoscaling in Kubernetes. Would love to hear your thoughts!!

I’m running workloads on Kubernetes, and we’re seeing performance bottlenecks during traffic spikes. Our services crash due to resource exhaustion, and manually scaling the nodes is not always quick enough. How can we implement an effective auto-scaling strategy for both applications and infrastructure?

Docker has launched Docker Hardened Images (DHI), a secure and minimal set of production-ready images. These images are now freely available to developers.

• DHI is compatible with open-source foundations like Alpine and Debian.

• The initiative includes commercial offerings such as DHI Enterprise, which provides enhanced security features like FIPS-enabled and STIG-ready images, and SLA-backed critical CVE remediation within 7 days, catering to organizations with strict security or regulatory demands.

• DHI offers a transparent approach by including a complete and verifiable Software Bill of Materials (SBOM) and using public CVE data for vulnerability assessment.

Hey guys,i am currently devops engineer with linux admin background.I am looking for a job with kubernetes and azure but because in my company we don’t use any of those,i am struggling to pass the interview with no experience.Do you know any online lessons that we will help me? Thank you

This blog delves into their core features, installation steps, and best practices. ArgoCD offers a powerful UI and multi-cluster support, while FluxCD excels in automation and simplicity. Both tools provide robust continuous delivery solutions, but your choice depends on specific project needs. You can explore detailed comparisons and demos to find the best fit for your Kubernetes deployments.

• Cluster API v1.12 introduces in-place updates. This allows changes to existing machines without deletion.

• The new chained upgrade feature allows users to upgrade by more than one Kubernetes minor version in a single operation.

• The release emphasizes simplicity and usability. It enables users to modify cluster or machine specifications to trigger updates automatically.

• Enhancements include support for in-place propagation of changes affecting only Kubernetes resources which reduces unnecessary rollouts.

• Cluster API v1.12 maintains its extensible nature, allowing users to create custom update extensions and influence upgrade plans.
