Know the differences between ConfigMaps mounted as Volumes and ConfigMaps defined as environment variables.

Argo Event is a Kubernetes based event automation engine. It is part of the Argo project. Argo Events can be used with or independent of other projects in Argo.

I will be writing a series of articles on Argo Events; in these articles I will be looking at how we can use Argo Event to automate process within and without a Kubernetes cluster.

For this first article in this series, we will examine Argo Events core concepts, installation and provisioning different event buses which Argo Event uses to forward events to their sink. Finally we will look at setting up a webhook event flow to verify our setup.

The nuances of how users and groups are configured in Kubernetes and how the role-based access control (RBAC) mechanism applies for them.

Understand Kubernetes Events and learn to use kubectl events to monitor and troubleshoot your cluster’s issues effectively.

Kubernetes schedules GPU workloads by assigning a whole device to a single job exclusively. This one-to-one relationship leads to massive GPU underutilization, especially for interactive jobs, characterized by significant idle periods and infrequent bursts of heavy GPU usage. Current solutions enable GPU sharing by statically assigning a fixed slice of GPU memory to each co-located job. These solutions are not suitable for interactive scenarios since the number of co-located jobs is limited by the size of physical GPU memory. Consequently, users must know the GPU memory demand of their jobs before submitting them for execution, which is impractical.

The GitOps Bridge is a community project that aims to showcase best practices and patterns for bridging the process of creating a Kubernetes cluster to subsequently managing everything through GitOps. It focuses on using ArgoCD or FluxCD, both of which are CNCF-graduated projects.

Since long before I worked at HashiCorp I've been interested in the problems with how Terraform interacts with security-sensitive information like passwords and private keys.

Embrace engineers share a few key learnings from supporting larger log sizes, including working around a current limitation in ClickHouse and testing several skip indices to optimize query performance and storage cost.

Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Built on Talos Linux by the folks at Sidero.

NGINX Gateway Fabric is an open-source project that provides an implementation of the Gateway API using NGINX as the data plane.

Posting is an HTTP client, not unlike Postman and Insomnia. As a TUI application, it can be used over SSH and enables efficient keyboard-centric workflows. Your requests are stored locally in simple YAML files, meaning they're easy to read and version control.

Wave is an open-source AI-native terminal built for seamless workflows.

Wave isn't just another terminal emulator; it's a rethink on how terminals are built. Wave combines command line with the power of the open web to help veteran CLI users and new developers alike.

An open-source distributed object storage service tailored for self-hosting

What's the difference between service degradation, service disruption, and service outage and why does it matter?

In this post we will learn about a new feature available in Terraform 1.9 that allows us to reference any type of object in our variable validation blocks.

Engineering orgs that use IaC tools like Terraform aren’t typically maximizing their leverage. This article highlights at least three uses of Terraform and IaC automation that don’t necessarily center around traditional application workload infrastructure.
