Kubernetes, a tool for managing and automating containerized workloads in the cloud.

Imagine you have an orchestra.

Think of each individual musician as a Docker container.

To create beautiful music, we need a conductor to manage the musicians and set the tempo.

Now imagine the conductor as Kubernetes and the orchestra as an app like Robinhood.

When the markets are closed, an app like Robinhood isn't doing much.

But when they open, it needs to fulfill millions of trades for overpriced stocks like Tesla and Shopify.

Kubernetes is the tool that orchestrates the infrastructure to handle the changing workload.

It can scale containers across multiple machines, and if one fails, it knows how to replace it with a new one.

A system deployed on Kubernetes is known as a cluster.

The brain of the operation is known as the control plane.

It exposes an API server that can handle both internal and external requests to manage the cluster.

It also contains its own key value database called etcd, used to store important information about running the cluster.

What it's managing is one or more worker machines called nodes.

When you hear node, think of a machine.

Each node is running something called a kubelet, which is a tiny application that runs on the machine to communicate back with the main control plane mothership.

Inside of each node, we have multiple pods, which is the smallest deployable unit in Kubernetes.

When you hear pod, think of a pod of whales or containers running together.

As the workload increases, Kubernetes can automatically scale horizontally by adding more nodes to the cluster.

In the process, it takes care of complicated things like networking, secret management, persistent storage, and so on.

It's designed for high availability, and one way it achieves that is by maintaining a replica set, which is just a set of running pods or containers ready to go at any given time.

As a developer, you define objects in YAML that describe the desired state of your cluster.

For example, we might have an NGINX deployment that has a replica set with three pods.

In the spec field, we can define exactly how it should behave, like its containers, volumes, ports, and so on.

You can then take this configuration and use it to provision and scale containers automatically, and ensure that they're always up and running and healthy.

This has been Kubernetes in 100 seconds.

結構	影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	are closed · is known
定語從句 who / which + 從句 — 補充說明人或事物	kubelet, which is · pods, which is · set, which is

需要注意的發音

“sh” 和 “zh” 音: musician /mjuˈzɪʃən/, configuration /kənˌfɪɡ.əˈɹeɪ̯.ʃən/, speculation /ˌspɛk.jəˈleɪ.ʃən/

如何用這段影片練習

先完整聽一遍影片，不要開口，記下不認識的單詞。
先用 0.75 倍速逐句跟讀，熟練之後再回到正常速度。
錄下自己的聲音並與原聲對比，特別注意 container, node, cluster 這類單詞。

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
