Secret Management 的議題一直以來都是 CI/CD 流程中不可忽似的一部分，本篇文章作者不同於以往採用常見的解決方案(Hashicorp Vault, Helm Secret, SealedSecret)，反而是使用 Helm 內建的 AES 加解密功能來實作 Heml Chart 資料的加解密需求。

作者認為一個良好的機密管理解決方案需要能夠為其團隊提供三個基本需求
1) 所有的機密資訊都要能夠存放到版本控制系統中(Git...etc)
2) 所有被上傳到 Chartmuseum 的 Helm Chart Package 都不能有任何 k8s secret 物件，要放的只能有加密後結果。反之使用者要使用時也必須要有能力去解密
3) 單一工具管理，以作者來說會希望能夠都使用 Helm 這個工具來處理，愈少的工具意味者依賴性愈少，同時在維護與管理上要花的心力也更少。

作者首先列舉了兩個現存的專案，分別是 Helm Secrets 以及 Hashicorp Vault 並且針對這兩者進行了簡單的介紹，並且舉出為什麼這兩個專案並不適合作者團隊的需求與使用情境。

作者最後開始認真研究 Helm 本身有什麼內建的加解密功能可以使用，最後發現 encryptAES 以及 descryptAWS 這兩個內建函式可以使用，譬如

value: encryptAES "secretkey" {{ .Values.valueToEncrypt }}
value: {{ .Values.valueToDecrypt }} | decryptAES "secretkey"

有了基本的概念與用法後，作者透過 shell script 實作一層 wrapper 來簡化整個處理流程。
最後將這些資訊也導入到 CI/CD 流程中來幫忙進行解密的相關動作，讓 CD 可以順利的將目標 Secret 給送到 Kubernetes 中。

個人心得: 採用加解密的系統個人還是喜歡採用 SealedSecret 的設計理念，將解密的時間點延後到 Kubernetes 內而並非 CI/CD 系統上，主要是 CI/CD 的 pipeline 要是沒有仔細設計其實很多人會不小心把過程命令給輸出的，這樣的話加解密的過程，使用的 Key 等都有可能會洩漏出去。

English Learning Ecosystem Update

As I began exploring Instagram, I struggled to find a way to deliver useful academic content. Instagram posts typically focus on images, short clips, and concise text, which are attention grabbing but not always entirely conducive to language learning. I looked over the posts of established Instagram English learning accounts, and experimented with vocabulary posts and even news posts for a couple of weeks. Not wanting to post just images, I thought about creating something new even with the rigid format of the platform.

當我開始研究怎麼用IG，我想盡了各種辦法，希望能提供大家一些實用的學術內容。 IG 的特色著重在圖片、短片以及簡潔的文字，這樣的方式雖然很容易引人注目，卻不全然有助於語言學習。我瀏覽了 IG 上英文教學網紅的貼文，並在這幾週嘗試發了一些學術單字與新聞相關的文章。我並不想只是發一些圖片，而思考著要如何在既有框架下創作一些新的東西。

★★★★★★★★★★★★

A tenet of using tech in education is to engage students with what they are familiar with, not give them an entirely new platform that is difficult to use. So, how could I create a new series of Instagram posts that is both educational and unique? I thought about my goal to disseminate academic English resources, and how I could leverage my experience as a curriculum writer and voice recording artist for public school textbooks.

一個使用科技進行教育的原則是用學生熟悉的方式與他們互動，而非用了全新的平台卻使他們難以學習。那麼，我應該如何創作獨特且具教育意義的一系列全新 IG 發文呢？我想到了我傳遞學術英文資源的目標，以及思考到該如何發揮身為教科書編輯者與音頻錄製者的經驗。

★★★★★★★★★★★★

So far, this is what I have at the moment. I will post Word of the Day (每日一詞), high frequency vocabulary words that you see in academic texts and sometimes on the news. These Tier 2 academic vocabulary words are not exclusive to a single domain and complement the theme-based approach I’ve taken with my mind-mapping vocabulary class. You can find other vocabulary learning methods here.

這是我目前所想到的內容：我會發布「每日一詞」，也就是學術文章或是新聞中有時出現的高頻字彙。這些Tier 2學術詞彙並不限於單個領域，更補充了我在心智圖詞彙攻略課程中採用的主題式學習法。你還可以在下面網站找到其他詞彙學習方法。

In these posts, I added the pronunciation, collocation, and example sentences of each word for students. These words will be helpful to university-level students who often read academic texts and the news. Students can access them by simply clicking on the hashtag 學術英語單字.

在這些貼文中，我為學生提供了發音、搭配用法和例句。這些單字會對經常閱讀學術文章和新聞的大學程度學生有所幫助。學生只要點貼文上的＃學術英語單字即可看到貼文。

To help students use more precise and common academic phrases, I then added Academic Phrases (每日一句), set phrases that appear in both academic speech and writing. These phrases have varying functions from introducing a topic to comparing and contrasting ideas. There is a difference between speech and writing, so I picked words that could be used for both. If one is used only in a specific context, I will make note of it in the video recording. This series of posts will help students with language output, and can be found under the following hashtag 學術英語片語.

為了幫助學生使用更精準、更道地的常見學術用語，我們接著會進入「每日一句」，也就是在學術演說與寫作中常見的用語。這些片語具有不同的功能，範圍涵蓋介紹主題到比較、對比想法等等。而演講和寫作之間也有不同，所以我選擇了都可以使用的片語。如果只能在特定情況下使用，我會在影片中特別說明。該系列文章將會幫助學生提高語言輸出能力，可以在 # 學術英語片語找到。

Last, I will follow up with an abridged version of breaking news (時事英文) with high frequency collocations and audio recordings. This will provide students with the input of not only individual words, but how to use them in output (speech and writing) with context. While all these news posts might seem independent at first, I will eventually link and organize them by theme when there are enough posts. Along with my news class, these extra posts will help students stay aware of current events, acquire set phrases used in journalism, and develop critical thinking. These posts can currently be found under the hashtag EEL時事英文.

最後，我們會跟進精簡版的「時事英文」，其中包含高頻搭配詞與錄音資料。這些內容不僅可以提供你們輸入單字，而且可以幫助你們知道如何搭配情境輸出，再將這些內容使用在口說與寫作中。這些貼文一開始雖然看似獨立，當素材足夠後我會再將他們進行連結與整理。這些貼文和我的新聞課程將幫助學生維持對時事的敏銳度，掌握新聞中使用的固定用法，並養成批判性思維。這些貼文目前可以在 # EEL時事英文。

There is a lot more I want to do to create an ecosystem of free academic English learning materials. I will continue modifying our post format to meet your needs, but these are my plans for Instagram thus far. Join us on our journey to make bilingual academic English resources more readily available to all! Let’s continue to learn and grow together!

建立免費的學術英文學習系統是件大工程，我會持續修改我們發文的格式以符合你們的需求與習慣，這些只是我目前 IG 學術英語學習計畫的一部分。加入我們的旅程來讓雙語的學術英文資源更加普及！讓我們一起學習與成長！

To be honest, I haven’t updated YouTube for awhile because of the high cost of producing a video (both money and time). However, you can still check out the channel for English learning videos, and I will update it whenever I can.

Our blog, which gets about 2000 visitors a day, is a compilation of all the free resources I published on all media. Thus, if you do not want to get on FB, feel free to check it out.

說實在的，因為做一部影片要成本過高，我已經一陣子沒有更新YouTube。 但是你還是能夠在頻道上觀看英文學習影片，如果有值得我們關注的議題就會有所更新。

我們的部落格每天有大約2000人來訪，匯集了所有我網路上免費資源；所以如果你不想上臉書，歡迎使用我們的部落格。

I started working on Instagram a few months ago and so far I have three types of posts:

我幾個月前也開始投入IG！目前有三種貼文：

1. Word of the Day: I go over the pronunciation, collocations and provide example sentences. All these words are high frequency tier-2, cross-domain vocabulary words that appear in both academic texts and the news.

每日單字：我會針對發音、搭配詞、單字用法進行說明。所有的單字都來自高頻Tier 2跨領域學術詞彙，你會常在學術文章和新聞看到它們。

2. News English: I publish abridged, translated, and audio versions of news stories found in the NY Times, Reuters, the Guardian, and so on. These take a bit of time to do, so please use these resources as a part of your learning.

時事英文：我會發布來自紐約時報、路透社、衛報等網站的新聞，並且花了不少時間提供三合一服務（新聞摘要、翻譯、有聲版）。言下之意就是多使用這些資源吧！

3. Daily life English topics: Anything that I find interesting or useful to students

生活英文主題：只要是有趣或是實用的資訊都會出現～

So, if you need any of these resources, feel free to follow. Everything is free and I will do my best to keep it that way. Do follow me on Instagram if you need News English and want to expand your vocabulary!
