⭐Kubernetes instance calculator
The Kubernetes instance calculator is a tool that gives you a quick estimate of the resources you'll need to run your applications on Kubernetes. It considers the number of pods, their resource requests and limits, and the available resources on the nodes. While not exact, it provides a rough idea to help with planning. The calculator is based on research around Kubernetes node memory and CPU allocation, cluster architecture, and instance type trade-offs.
⭐5 Advanced Kubernetes operators every DevOps engineer should know about
Managing Kubernetes clusters can be challenging, but advanced Kubernetes Operators can simplify and automate these tasks. Operators are custom controllers that extend Kubernetes capabilities, automating the management of applications and ensuring smooth operation with minimal manual intervention. Advanced operators handle complex workflows, reduce human error, and improve system reliability and performance.
⭐6 Essential Linux command line tools for DevOps engineers
Essential commands like `yq` for parsing YAML, `sed` and `grep` for updating configurations, `curl` for checking API statuses, `tee` for logging, and `watch` for real-time monitoring are indispensable. By mastering these commands, DevOps engineers can streamline their workflows, automate tasks, and handle complex scenarios with ease, making them more effective in their roles.
⭐How I discovered the Organization ID of any AWS Account
While researching AWS security, Sam discovered a technique that allowed him to identify the Organization ID of any AWS account by exploiting VPC Endpoint policies. By testing wildcards in these policies, he could determine the account's ID without being detected by CloudTrail, which doesn’t log policy denials. This method raised significant security concerns, as it could link AWS accounts to a central organization without permission. AWS quickly addressed the issue by implementing restrictions on wildcard usage in VPC Endpoint policies, effectively closing the loophole.
⭐Tips for troubleshooting the target allocator
When troubleshooting the Target Allocator in the OpenTelemetry (OTel) Operator, start by ensuring that all necessary resources, like ServiceMonitors or PodMonitors, are actually deployed to Kubernetes. Verify that the Target Allocator is enabled and configured to discover scrape targets by checking that service discovery is working properly. Make sure that your ServiceMonitor or PodMonitor configurations, such as labels, namespaces, and ports, match those expected by the Target Allocator. Lastly, ensure that selectors like `serviceMonitorSelector` or `podMonitorSelector` are correctly configured to avoid missing target discovery.

🔍Secret Knowledge: Learning Resources
🔍What's your preferred logging stack in Kubernetes
A user on Hacker News is seeking advice on logging solutions for Kubernetes, as their current Graylog setup is challenging to maintain with system growth. They're considering alternatives due to issues with index management in Elasticsearch and MongoDB reliability. Responses from the community suggest various tools like VictoriaLogs, ClickHouse, Loki, and Quickwit, each offering different advantages in terms of performance, cost, and ease of use. While some prefer simple setups like rsyslog or hosted services like Google Cloud Logging, others have found success with more robust solutions like ELK or Sumo Logic.
🔍Patching image vulnerabilities with Kubescape & Copa
In this article, you'll learn how to patch vulnerabilities in your container images using Kubescape, an open-source Kubernetes security platform, and Copa. Container images often have security vulnerabilities, either at the OS level (due to the underlying operating system) or the application level (due to issues in the code). Kubescape scans these images for vulnerabilities, then Copa steps in to patch them by updating the necessary packages. The patched images are then re-scanned to ensure the vulnerabilities have been fixed, helping to maintain secure container deployments.
🔍Are my AWS Resources Encrypted or Unencrypted by Default?
This article explores whether AWS resources are encrypted or unencrypted by default, focusing on the trend of "secure by default" in cloud security. After examining 43 AWS services and 51 resource types, the findings show that 76.47% of these resources are encrypted by default, using either AWS Owned or Managed Keys. However, 23.53% remain unencrypted by default, highlighting the need for vigilant encryption practices. The article also offers best practices for managing encryption in AWS, emphasizing the importance of monitoring key policies and ensuring resources are encrypted to meet compliance and security requirements.
This blog post is the first in a series exploring the evolution of the Hypertext Transfer Protocol (HTTP), starting with its earliest version, HTTP/0.9. Introduced in 1991, HTTP/0.9 was a simple protocol that enabled basic communication between web browsers and servers, forming the foundation of the modern web. It only supported the GET method for retrieving resources, and lacked headers, status codes, and other features that later versions would introduce. The post includes a hands-on tutorial to build an HTTP/0.9 server and client in Go, offering insights into the protocol’s simplicity and limitations.
The proposed `terraform plan -light` flag aims to speed up Terraform plan times by only targeting resources that have been modified in code. Instead of refreshing the state for all resources, which can be time-consuming, this flag would focus the refresh and plan process solely on resources that differ from their last applied state. By storing a hash of each resource's attributes after a successful apply, Terraform can compare the current and previous states to identify changes. This approach reduces plan duration without sacrificing consistency.

⚡How AWS powered Prime Day 2024 for record-breaking sales
During Prime Day 2024, AWS powered Amazon’s biggest shopping event ever by scaling its cloud infrastructure to handle massive global demand. AWS deployed over 80,000 AI chips and 250,000 Graviton processors, ensuring seamless performance for over 5,800 services, including AI-driven features like Rufus. Amazon’s cloud storage and database services managed trillions of operations and petabytes of data, while tools like CloudFront and DynamoDB handled billions of requests, maintaining high availability and low latency.
⚡Kubernetes v1.31: Elli has 45 new features
Kubernetes v1.31, named "Elli," introduces 45 new features, including 11 that have reached stable status, 22 in beta, and 12 in alpha. Highlights include improved security with stable AppArmor support, enhanced ingress connectivity, and the ability to track Persistent Volume transitions. Beta features like nftables backend for kube-proxy and traffic distribution improvements also stand out. The release also marks the first update after Kubernetes' 10th anniversary, reflecting on the project's evolution and the strong community spirit that continues to drive its progress.
⚡New OpenAI feature for developers on Azure
Microsoft Azure has introduced a new feature in the latest OpenAI model, GPT-4o-2024-08-06, aimed at enhancing developer productivity.
