You can now migrate running VMs across Kubernetes nodes without network disruptions or packet drops. A huge win for stateful workloads in K8s.The Hidden Gaps in Kubernetes Audit Logs and How They Can Break Your DetectionsThere are real-world problems with relying solely on Kubernetes audit logs for security, like missing events, inconsistent log formats across providers (like GKE vs. EKS), and limited control over audit policies, all of which can lead to missed attacks and broken detections. It also offers practical strategies to fill these gaps with additional logging and monitoring sources.Why a Giant K8s Cluster (with vCluster) Might Be Your Best BetConsolidating everything into a single large Kubernetes cluster boosts efficiency, reduces overhead, and simplifies operations. It also tackles the downsides like blast radius and multi-tenancy by introducing vCluster, a tool that creates fully isolated virtual clusters within a host cluster. The result? You get the best of both worlds: centralized control with team-level autonomy.🔍 Observability & SRENew Cloud Trace features to troubleshoot latency and errors | Google Cloud BlogGoogle Cloud’s new Trace Explorer makes debugging services easier with span heatmaps, percentile duration charts, and filters — all powered by BigQuery.

Instead of alerting everyone for every issue, teams can define what they own, set their own performance budgets, and use strategies like caching or retries to absorb downstream failures. The result? Less noise, clearer accountability, and a better user experience.A Practical Guide to Using OpenTelemetry and the OTel Collector for Full-Stack ObservabilityThis article explains how to use OpenTelemetry and the OTel Collector to collect logs, metrics, and traces from your apps and infrastructure. It shows how to configure receivers for Redis, MySQL, and NGINX, and how to export data to backends like Prometheus or Jaeger. The goal is to help you build a flexible, scalable observability pipeline using open standards.How a Concurrency Bug Caused 3200% CPU UtilizationThe author debugged a Java program using 3,200% CPU and traced it to multiple threads writing to an unguarded TreeMap, causing data corruption and an infinite loop inside the red-black tree structure. The bug wasn’t immediately visible because exceptions were swallowed silently by thread pools. Through experiments, they confirmed how concurrent modification can break TreeMap, not by crashing it, but by corrupting its internal structure into cycles.🌐 Industry, Tools, AI & OtherGemini Code Assist: A Framework for AI Dev Tools AdoptionGoogle Cloud proposes a four-phase model (Adoption → Trust → Acceleration → Impact) to roll out AI code tools like Gemini.

Whether you're automating tasks, troubleshooting servers, or just making your daily workflow smoother, scripting saves time and headaches. The Ultimate Linux Shell Scripting Guide caught my eye because it doesn’t just focus on Bash—it also dives into Zsh and even PowerShell on Linux. If you’re looking to sharpen your command-line skills and build real-world automation, this one is worth a read. GET IT Forward to a Friend ⭐MasterClass: Tutorials & Guides The Kubernetes gap in CNAPP Initially, CNAPPs focused on integrating various cloud security tools and supporting enterprises during early cloud adoption. As a result, their Kubernetes protection often lacks depth and focuses mainly on surface-level issues like container vulnerabilities, without addressing the complexities of Kubernetes clusters, such as control plane security or runtime policies. This has led to a false sense of security in cloud environments, as CNAPPs fail to offer robust Kubernetes-specific features. Unlock Kubernetes Savings with Kubecost’s Automated Actions Kubecost's new automated actions help users save money in their Kubernetes environments by optimizing resource usage with minimal effort. With features like automated request sizing, cluster turndown, and namespace turndown, Kubecost identifies inefficiencies like over-provisioned containers and shuts down unused clusters or namespaces. Users can set schedules for automating these actions, reducing waste and freeing up resources. How WebAssembly components extend the frontiers of Kubernetes to multi-cloud, edge, and beyond WebAssembly (Wasm) components enable Kubernetes to extend seamlessly across multi-cloud, edge, and other distributed environments by providing a lightweight, portable way to run applications across any architecture. Wasm components, similar to containers, can be written in various languages and connected through shared APIs, allowing for greater flexibility and efficiency. By integrating with Kubernetes through wasmCloud, a Wasm-native orchestrator, organizations can enhance their cloud-native setups without changing existing infrastructure. How to migrate an observability platform to open-source and cut costs Migrating an observability platform to open-source can significantly reduce costs while maintaining control over telemetry data, but it requires careful planning and execution. This process involves identifying essential telemetry data, selecting an open-source stack for logs, metrics, and traces, conducting proofs-of-concept (POCs) across different systems, and ensuring compatibility with various architectures, such as microservices. The migration also includes reconfiguring alerts and dashboards, validating the new setup, and updating related systems like notification and incident management tools. 🔍Secret Knowledge: Learning Resources Implementing GitOps with Kubernetes: Automate, manage, scale, and secure infrastructure and cloud-native applications on AWS and Azure This book provides practical guidance on using GitOps to automate and manage Kubernetes deployments in cloud-native environments like AWS and Azure. It explains core GitOps principles, tools like Argo CD and Flux, and strategies for implementing CI/CD pipelines. The book also covers infrastructure automation with Terraform, security best practices, and observability while addressing cultural transformations in IT for GitOps adoption. By the end, readers will have skills to apply GitOps in scaling, monitoring, and securing Kubernetes deployments efficiently. Complete Guide to Logging in Golang with slog In Golang, structured logging can be efficiently implemented using the `slog` package, introduced in version 1.21. `slog` allows for more organized and detailed log entries by formatting logs as key-value pairs, making them easier to search, filter, and analyze. The package provides flexibility with logging levels (like Debug, Info, Warn, and Error) and supports both text-based and JSON-formatted output. Key components include Loggers, Records, and Handlers, which define how logs are created, stored, and processed. Scaling Prometheus with Thanos Scaling Prometheus with Thanos allows for long-term storage, cost savings, and a global view of metrics in large environments. While Prometheus is great for short-term monitoring, it struggles with long-term storage and querying across multiple clusters. Thanos extends Prometheus by using components like Thanos Query, Sidecar, and Store Gateway to enable scalable, highly available storage through object stores, reducing Prometheus's resource consumption. It also supports downsampling to optimize storage and query performance. Automated container CVE and vulnerability patching using Trivy and Copacetic Automating container vulnerability patching with Trivy and Copacetic (copa) helps protect your applications from potential attacks by scanning and patching container images automatically. Trivy scans container images for vulnerabilities, generating a report in JSON format, while Copacetic reads this report and patches the container image based on detected vulnerabilities. Once patched, the image is rebuilt and rescanned to ensure all vulnerabilities have been fixed. Self-signed Root CA in Kubernetes with k3s, cert-manager and traefik In Kubernetes with k3s, cert-manager, and Traefik, you can create a self-signed root Certificate Authority (CA) to manage TLS certificates locally, useful when your cluster isn't exposed to the internet (e.g., no Let's Encrypt). The process involves setting up cert-manager to automate the issuance, renewal, and secret management of these certificates. You first create a self-signed root CA, which then signs an intermediate CA, and that intermediate CA signs leaf certificates for your services. This setup allows your services to have trusted certificates locally. ⚡TechWave: Cloud News & Analysis Google Cloud, AWS, and Azure have collaborated to introduce Kube Resource Orchestrator (kro), a Kubernetes-native tool that simplifies managing Kubernetes resources by grouping them into reusable APIs. kro allows platform and DevOps teams to define standardized deployments while hiding complexity from end users.

They use probes to monitor container health and take corrective actions when necessary. The three main types of probes—Liveness, Readiness, and Startup—serve distinct purposes. Liveness probes ensure the application is running and can restart containers in case of failure. Readiness probes determine if a container is ready to handle traffic, temporarily removing it from service if it fails. Startup probes focus on verifying successful initialization for slow-starting applications. Probes can use methods like HTTP, TCP, commands, or gRPC to perform health checks.How to manage secrets with Azure Key Vault in Kubernetes?To manage secrets with Azure Key Vault in Kubernetes, you can use tools like the External Secrets Operator (ESO) and a service principal for authentication. Start by creating an Azure Key Vault, adding your sensitive data (e.g., API tokens) as secrets, and assigning the required permissions to a service principal. Install ESO on your Kubernetes cluster to synchronize secrets from Azure Key Vault to Kubernetes secrets. Then, configure a SecretStore resource in Kubernetes to connect to the Key Vault, using the service principal credentials for authentication. With this setup, applications running in Kubernetes can securely access secrets from Azure Key Vault without exposing sensitive data.Self-Hosting a Container RegistryA self-hosted container registry allows you to store and manage container images on your own infrastructure, giving you full control and independence from third-party services. It involves setting up a server with Docker, configuring a container to run the registry, securing it with user authentication (e.g., via htpasswd), and enabling HTTPS using Nginx and SSL certificates. Once configured, you can push and pull images securely from your registry. While self-hosting ensures privacy and compliance with strict regulations, it requires maintaining and securing the system yourself, making it ideal for enterprises needing tight control over their containerized workflows.How I tuned my CI/CD pipeline to be done in 60 secondsThe process of optimizing my CI/CD pipeline to run in under 60 seconds involved strategic improvements in parallelization, caching, and job refinement. Initially, my pipeline was a simple setup that took over five minutes to execute, which hampered my productivity. I split the pipeline into multiple parallel jobs, grouped similar tasks to save cost and debug time, and leveraged GitHub's caching for dependencies, linting tools, and test data to drastically reduce redundant downloads and processing. By using a Makefile for local testing, I accelerated iterations and ensured the GitHub YAML was simple and reliable. Further tuning, like combining related jobs and adding task-specific cache keys, helped balance speed and cost. These optimizations allowed me to reduce the runtime for building, testing, linting, and deploying my Golang app to under a minute, making the pipeline more efficient and developer-friendly.What Karpenter v1.0.0 means for Kubernetes autoscalingKarpenter v1.0.0 marks a significant milestone for Kubernetes autoscaling, offering a mature and stable solution for dynamic node lifecycle management. As an open-source tool designed to optimize workload placement and reduce costs, Karpenter automatically provisions and deprovisions nodes based on application demands and Kubernetes scheduling constraints. With its vendor-neutral design and integration with cloud-specific APIs like AWS, Azure, and GCP, Karpenter enhances scalability, cost-efficiency, and ease of management across diverse cloud environments. The 1.0 release ensures API stability, supports features like workload consolidation and rolling updates for node images, and enables seamless integration with other CNCF tools, empowering organizations to build intelligent and scalable cloud-native infrastructure.🔍Secret Knowledge: Learning ResourcesFive Lessons from a Minor Production IncidentA minor production incident in the AWS News platform highlighted five key lessons about software operations. First, investing in observability early paid off, as comprehensive dashboards allowed for quick identification and resolution of the issue within an hour. Second, a robust software architecture and testing regime enabled safe and confident adjustments to the system during a crisis. Third, the YAGNI principle (You Aren't Gonna Need It) has trade-offs; while simpler designs work initially, anticipating growth with safeguards like alarms could prevent issues. Fourth, bugs often travel in pairs, as one problem often uncovers or triggers another, underscoring the need for thorough debugging processes. Lastly, data lineage simplifies troubleshooting, as stored intermediate data made it easy to pinpoint and fix the root causes. These lessons underscore the importance of building resilient systems even for small-scale projects.Making a Postgres Compound Index 50x FasterOptimizing a compound index reduced query latency by 50x, showcasing the importance of index field order in PostgreSQL. Initially, a query filtering by status and event_type, and sorting by occurred_at, was slow due to an index ordered by occurred_at first. This structure forced PostgreSQL to scan millions of rows inefficiently. By reordering the index to prioritize filter fields (status, event_type) before the sort field (occurred_at), the search space narrowed significantly, enabling PostgreSQL to process only relevant subsets. This simple yet impactful adjustment improved endpoint latency from ~500ms to under 10ms, highlighting how understanding index design can drastically enhance database performance.SQLite Index VisualizationSQLite uses a B-Tree structure to organize indexes, ensuring efficient data storage and quick searches. A B-Tree consists of nodes, with each node storing cells that contain the indexed data, a row ID, and links to child nodes. The data is saved on pages, which have fixed sizes, and every index is structured hierarchically for balance and fast lookups. Using tools like sqlite3_analyzer, we can inspect indexes and visualize their layout, which includes pages, cells, and relationships.

Multi-tenancy with virtual Kubernetes clusters offers a cost-efficient solution by enabling multiple teams or applications to share a single host cluster while maintaining strong isolation and flexibility. Virtual clusters act like fully functional Kubernetes clusters within a host cluster, reducing redundancies and management fees while improving resource utilization.🔍Secret Knowledge: Learning ResourcesI followed the official AWS Amplify guide and was charged $1,100The author followed an AWS Amplify guide to integrate OpenSearch and ended up with a shocking $1,100 bill due to unexpected behaviors in the setup. Specifically, the guide’s default configurations created high-cost OpenSearch instances without making costs transparent, and resources were not properly deleted when shutting down the environment. The author identified issues like persistent OpenSearch domains and a lack of warnings about default expensive configurations. AWS refunded the charges and advised setting up budget alerts, but the problematic behavior in the guide still exists. The post cautions developers about potential pitfalls when using AWS Amplify with OpenSearch and highlights the importance of understanding AWS costs and configurations.What I wish someone told me about PostgresPostgres is a powerful but complex database system, and its vast official documentation can be overwhelming. Key tips for getting started include normalizing your data to avoid redundancy, except when performance optimizations (denormalization) are necessary. Understand SQL quirks like handling NULL as "unknown" and utilizing functions like COALESCE. Enhance the usability of psql by configuring features like pagers and shortcuts (e.g., \x for expanded view). Use indexes wisely, considering their order and suitability for different queries (e.g., prefix searches need text_pattern_ops). Be cautious with locks during operations like ALTER TABLE, as long-held locks can disrupt other processes. Embrace tools like query plans (EXPLAIN) to optimize performance, and always start with the Postgres documentation and community advice for best practices.Choose the Right Instance Size for AWS RDSTo choose the right AWS RDS instance size, start by evaluating your workload's needs in terms of CPU, memory, storage, and network bandwidth. Use AWS instance families to match these requirements, with memory-optimized instances for RAM-intensive tasks and burstable instances for cost-sensitive, sporadic workloads. Monitor key performance metrics, like CPU utilization, freeable memory, and network throughput, using AWS CloudWatch, and adjust the instance size based on consistent patterns—scale down if utilization is low and up if demands are high. Optimize performance with database tuning and continuously revisit your setup to balance cost, scalability, and performance effectively.Building databases over a weekendBuilding a database over a weekend is made feasible with tools like Apache DataFusion, which simplifies creating custom database functionalities. DataFusion provides a modular framework where you can extend or replace components like query parsing, logical and physical planning, and execution engines.

Informers and SharedInformers optimize resource management by efficiently watching changes in objects, reducing API server load. Informers utilize Reflectors to fetch and cache data, Listers to retrieve objects from the cache, and Workqueues to process events like Add, Update, or Delete. Controllers act as loops that continuously reconcile the current state of resources (from their status) with the desired state (defined in their spec).How we avoided an outage caused by running out of IPs in EKSAdevinta's platform team tackled the critical issue of IP exhaustion in their EKS clusters by implementing custom networking with a secondary CIDR to allocate additional IPs, avoiding potential outages. The problem stemmed from the VPC-CNI plugin's default behavior of assigning an IP address per pod, which strained available IPs in their VPC as clusters scaled. While alternatives like switching to Cilium or enabling IPv6 were explored, the chosen solution balanced speed and reliability, enabling the team to complete their migration to EKS. By carefully testing and rolling out custom networking, the team stabilized IP usage, avoided service disruptions, and ensured seamless scaling for their multi-tenant cluster architecture.Deploying a Serverless REST APIThis guide walks you through deploying a REST API using AWS services like API Gateway, Lambda, DynamoDB, and Cognito with Terraform. The project involves creating an API that allows users to manage a list of Sicilian dishes. It starts with configuring AWS as the provider and setting up an S3 bucket to store Terraform state files. You then create an IAM role with the necessary permissions for Lambda to interact with DynamoDB. The Lambda function itself is written in Python, with methods to handle CRUD operations on the DynamoDB table based on the incoming HTTP requests. Authentication is added via Amazon Cognito to secure write operations. Finally, the API routes (GET, POST, PATCH, DELETE) are implemented to handle the dish data, including a recursive scan function to fetch all dishes from the table.🔍Secret Knowledge: Learning ResourcesHow to Differentiate Manual Changes from Terraform Changes in S3 BucketTo differentiate manual changes from Terraform changes in an S3 bucket managed by Terraform, you can use AWS CloudTrail, EventBridge, Lambda, and SNS notifications. CloudTrail logs all S3 API actions, including manual and automated changes. EventBridge filters these logs for specific events (e.g., uploads or deletions) and triggers a Lambda function. The Lambda function processes the events to exclude actions initiated by Terraform (using the IAM role or userIdentity details associated with Terraform). It sends SNS notifications only for manual changes, ensuring Terraform modifications do not trigger alerts.Managing AWS EKS access entries with Terraform and OpenTofuManaging AWS EKS access entries with Terraform and OpenTofu simplifies authentication and authorization for Kubernetes clusters by replacing the outdated aws-auth ConfigMap with a more scalable and robust EKS API. Access entries allow direct API-based management of IAM users, roles, and predefined policies, eliminating manual ConfigMap updates prone to errors.

There are two main types: Layer 4 (L4) and Layer 7 (L7) policies. L4 policies manage traffic at the transport layer (e.g., TCP/UDP) based on IP addresses and ports, while L7 policies operate at the application layer (e.g., HTTP) with more fine-grained control over communication between services. L7 policies often require a service mesh like Linkerd, which adds features like mutual TLS (mTLS) for encrypted communication.Dockerfile Instructions - ADD vs. COPY`COPY` is simple and secure, only transferring files from the local build context to the image. In contrast, `ADD` offers extra functionality, such as downloading files from URLs or automatically extracting compressed archives. However, this added flexibility introduces complexity and potential security risks. Best practice recommends using `COPY` for most cases due to its straightforwardness, reserving `ADD` for situations where its unique features are necessary.How to add new worker node to existing Kubernetes clusterTo add a new worker node to an existing Kubernetes cluster, start by setting up a new Ubuntu 24.04 instance and configuring its hostname and `/etc/hosts` file. Disable swap memory, load necessary kernel modules, and install containerd as the container runtime. Add the Kubernetes APT repository, then install Kubernetes components like kubeadm, kubelet, and kubectl. On the control plane node, generate a kubeadm join command with a token. Run this command on the new worker node to join the cluster. Finally, verify the addition by checking the nodes from the control plane using `kubectl get nodes`.How I Reduced Docker Image Size from 588 MB to Only 47.7 MBTo significantly reduce a Docker image size, using multi-stage builds is key. In this case, a Flask app's image size was reduced from 588 MB to just 47.7 MB by switching to the lightweight Python 3.9-alpine image and using a multi-stage build approach. Multi-stage builds allow you to separate the build and runtime environments, keeping only essential runtime dependencies in the final image. Additionally, minimizing the number of layers by combining commands, using a `.dockerignore` file to exclude unnecessary files, and optimizing the Dockerfile structure contributed to this impressive 91.89% reduction.Ambient mesh: Can sidecar-less Istio make your application faster?Ambient mode in Istio, introduced in 2022, allows a sidecar-less architecture that can sometimes make applications faster. In traditional service meshes, adding latency is expected, but tests with ambient mode showed slightly improved performance in some cases, like the Bookinfo application's details service. This is partly because of more efficient connection handling and reduced syscalls in ambient mode, which offsets the overhead of extra hops via lightweight ztunnels.🔍Secret Knowledge: Learning ResourcesOops, I Deleted the AWS Auth RolesThe author, while managing an EKS (Elastic Kubernetes Service) cluster using Terraform, accidentally deleted the AWS authentication roles, which are crucial for accessing the cluster. This resulted in losing access to the EKS cluster. The fix involved manually restoring access by modifying the EKS API access configuration via the AWS Console, re-adding the necessary admin roles, and regenerating the `aws-auth` config map.Rising Incidents on Git PlatformsIn 2023, incidents affecting popular DevOps platforms like GitHub, Bitbucket, GitLab, and Jira increased, with issues such as RepoJacking, security vulnerabilities, and performance disruptions. GitHub saw a rise in attacks, with hackers exploiting vulnerabilities and hosting malware. Atlassian products like Bitbucket and Jira faced security flaws, with Jira experiencing a significant increase in incidents. GitLab suffered from performance issues and security breaches, including a major Proxyjacking attack.How Postgres stores data on diskPostgres stores data on disk in a well-organized, file-based structure within a directory, typically located at `/var/lib/postgresql/data`. Inside this directory, you'll find folders like `base/`, where actual database data for each database is stored, and `pg_wal/`, which holds the Write-Ahead Log (WAL) files that help recover data after crashes. Each table and database object is ultimately represented by files in these directories. PostgreSQL uses clever abstractions to manage data, such as snapshots for transactions, dynamic shared memory for handling multiple processes, and special mechanisms like tablespaces for physically separating certain data.How We Integrate a New Service in Under 1 Hour for 25 ClustersThe article describes how a team integrated a new service called Otterize across 25 clusters in under an hour, emphasizing that while the technical setup was quick, the lengthy licensing process took over four months. The integration involved automating several steps using GitOps and tools like Argo CD to avoid manual errors. Key tasks included creating an organization and environment, inviting users, integrating with Kubernetes, securely managing credentials, and deploying the setup through a script.Eleventeen ways to delete an AWS resourceOur goal is to reduce AWS costs, but the deletion methods vary widely, often leaving users frustrated. They categorize deletion patterns, from simple one-click deletes to more complex confirmations that require typing specific phrases or acknowledging consequences. Ultimately, AWS should standardize its deletion processes to improve user experience and security, and they call for more data on user behavior during these actions.🛠️HackHub: Best Tools for CloudApeman: AWS attack path management toolProject Apeman is an AWS attack path management tool that helps analyze and manage AWS security data. To set it up, you need Docker, Python, and a virtual environment.

Previously, access was managed using an "aws-auth" ConfigMap, which could be complex and prone to errors. Now, AWS introduces the EKS Access Management API, allowing users to authenticate through AWS IAM directly and authorize Kubernetes actions via Kubernetes RBAC. This approach removes the need for managing ConfigMaps manually, offers predefined EKS Access Policies, and enhances security by eliminating hidden root users. Additionally, integration with Terraform makes access control easier to implement and manage.How Netflix solved the issue with Java 21 virtual threadsIn Java 21, Netflix encountered an issue with virtual threads, which are lightweight threads designed to improve concurrency by suspending and resuming automatically. The problem involved some Netflix services using Java 21, Spring Boot 3, and Tomcat, where servers stopped processing requests due to sockets stuck in a `CLOSE_WAIT` state. Virtual threads were getting "pinned" to operating system threads while waiting to acquire locks. Since all OS threads became blocked, Tomcat couldn't process incoming requests, causing the system to hang. The underlying issue was traced to locking mechanisms in virtual threads, leading to thread contention and blocked OS threads.Does Talos Kubernetes and Omni live up to the hype?Talos Kubernetes and Sidero Omni live up to the hype by providing an intuitive and efficient way to set up and manage Kubernetes clusters.

He identifies that Windows applies an animation effect that delays interaction with the terminal. Through a series of tests and debugging, he discovers that the X server software (X410) adds unnecessary animation effects, which can’t be disabled directly. He uses a debugger to bypass the issue, improving the performance slightly. After further optimizations with features and caching processes, he brings the Windows terminal's performance closer to Fedora’s, significantly reducing the lag.Monitor these Kubernetes signals to help rightsize your fleetTo ensure your Kubernetes environment is both cost-efficient and sustainable, it's crucial to monitor signals like CPU, memory, disk I/O, and network utilization. Over-provisioning leads to wasted resources and high costs, while under-provisioning can degrade performance. Watch for indicators such as high resource usage, slow application performance, or low utilization to fine-tune your setup. Tools like Prometheus and Grafana, along with autoscaling, can help you dynamically adjust resources, ensuring optimal balance, reduced costs, and improved sustainability.Getting Started with Cilium Service Mesh on Amazon EKSThe blog post explains how Cilium, an open-source networking and security solution powered by eBPF, enhances network connectivity between workloads in Amazon EKS (Elastic Kubernetes Service).
