Writing a Custom Controller: Extending the Functionality of Your Cluster [I] - Aaron Levy Video

Writing a Custom Controller: Extending the Functionality of Your Cluster [I] - Aaron Levy, CoreOS

Much of the functionality in a Kubernetes cluster is managed by a reconciliation pattern within "controllers". The node, service, or deployment controllers (just to name a few) watch for changes to objects, then act on those changes to drive your cluster to a desired state. This same pattern can be used to implement custom logic, which can be used to extend the functionality of your cluster without ever needing to modify Kubernetes itself.

This talk will cover how to implement your own custom controller, from contacting the Kubernetes API to using existing libraries to easily watch, react, and update components in your cluster. By building on existing functionality and following a few best practices, you can quickly and easily implement your own custom controller.

About the Site 🌐

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.

About YouTube 📺

YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟

Content and Users 🎵

Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.

While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.

Monetization and Impact 🤑

YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.

As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
