Background In my daily work, in order to facilitate testing in a pure environment, I often need to frequently build and destroy clusters in local or public cloud environments. Sometimes in my HomeLab environment, although the CPU is not powerful, it is better because the memory is large enough. Later, after…

With the rise of cloud computing, the network infrastructure of enterprises has developed and evolved rapidly. Whether it’s public clouds, private clouds, or edge computing, they bring unprecedented opportunities and challenges to businesses. Traffic management technologies, such as CDN, tunnels, WAF, etc., …

This is the fifth installment in the series on Kubernetes networking learning, and it is planned to be the last one as previously outlined. Deep Dive into Kubernetes Network Model and Communication Understanding the Container Network Interface (CNI) Source code analysis: how kubelet and container runtime work with CNI Learning…

Transport Layer Security (TLS) is an encryption protocol designed to provide communication security for computer networks. This protocol is widely used in applications such as email, instant messaging, and IP voice, but its most common application is HTTPS. …

A few days ago, the Gateway API announced support for service mesh in version 0.8.0, signifying fresh developments in the GAMMA (Gateway API for Mesh Management and Administration) initiative, albeit currently at an experimental stage. Last June, when Gateway API released version 0.5.0, I penned an article exploring What does…

This article primarily delves into a source code analysis of the kubelet’s functions, key components, and its booting process, summarizing the working principle of kubelet. Kubelet Introduction From the official architecture diagram, it’s quite easy to locate the kubelet. The description of kubelet’s function is visible when executing kubelet -h: The kubelet…

This article predominantly introduces the Obsidian image upload plugin Image Upload Toolkit that I have developed. Background Why did I create this plugin? The story starts from last year. I realized that after six years of usage, Mweb Pro could no longer meet my requirements. Not that Mweb isn’t a good…
