Learn how to use MinIO to create S3-style storage in K8s and host static websites, with a simple CD pipeline that updates the site automatically

A Kubernetes Cluster API control plane provider that enables management of hosted control planes as first-class Kubernetes resources. This provider allows you to create and manage highly available Kubernetes control plane components (API Server, Controller Manager, Scheduler, and etcd) as hosted services, decoupling them from the underlying infrastructure.

In a Kubernetes (k8s) cluster, when Pods access external services, their Egress IP addresses are not fixed. In the Overlay network, the Egress IP address is determined by the node where the Pod resides. While in the Underlay network, Pods directly use their own IP addresses for external communication. Consequently, when Pods are rescheduled, regardless of the network mode, their IP addresses for external communication change. This instability poses a challenge for system administrators in managing IP addresses, especially as the cluster scales and during network fault diagnostics. Controlling egress traffic based on a Pod's original egress IP outside the cluster becomes difficult.

To solve this problem, EgressGateway has been introduced into the k8s cluster. It is an open-source EgressGateway designed to resolve egress egress IP address issues across various CNI network modes, such as Calico, Flannel, Weave, and Spiderpool. Through flexible configuration and management of egress policies, EgressGateway allows setting egress IP addresses for tenant-level or cluster-level workloads. When Pods need to access the external network, the system consistently uses the configured Egress IP as the egress address, providing a stable solution for egress traffic management.

taws provides a terminal UI to interact with your AWS resources. The aim of this project is to make it easier to navigate, observe, and manage your AWS infrastructure in the wild.

Worktrunk is a CLI for git worktree management, designed for running AI agents in parallel.

Worktrunk's three core commands make worktrees as easy as branches. Plus, Worktrunk has a bunch of quality-of-life features to simplify working with many parallel changes, including hooks to automate local workflows.

a friendlier ss / netstat for humans. inspect network connections with a clean tui or styled tables.

Here, we're going to cover the history, functionality, and performance of non-volatile storage devices over the history of computing, all using fun and interactive visual elements.

Terminal user interface for SSH.

If you ask 10 SRE engineers to define SRE, you'll get 11 definitions.

In this post, I will discuss if there is a difference between resilience and fault tolerance when talking about IT systems.

Datadog cut off our observability overnight. We migrated to an open Grafana stack in 48 hours. Here’s why vendor lock-in is fading in an AI-native world.

“I understand why we need to be blameless, but I have this person in my team who is often reckless. How can I not blame them when their actions continuously make things worse?”

Someone asked me this at the SRE meetup, right after my talk on incidents. Since then I’ve been thinking about it, because it surfaces a concern many people might have.
