過去的環境是開發人員在 Juypter notebook 上開發，但他們有時候會需要安裝依賴 Ubuntu 的 liberies，而安裝方法就是直接在 Terminal apt install。過去，我們為了讓他們方便開發，會直接用 Docker commit 的方式將開發環境打包成 image，但這段也讓後端協助人員多了跳進去洗頭的工夫。現在為了統一由 Git 管理，我們要開始想辦法將 “Ubuntu 的環境也納入管理”

• 初始想法

我原本的想法是新增一個 install.sh ，請開發人員有需要調整就進去修改，但這樣還是有人工的疑慮。有人工就會出錯。

• 想法改版

後來想到如果我直接將現有環境的 liberies 找出來，打包時部署進去是否就可以解決了呢？於是找到了 dpkg 指令。但這個指令包含了超多預設的 liberies，抓出來竟有 600 多個。

$ dpkg --get-selections

• 想法再改版

那會不會能夠找出有哪些環境是額外被建立出來的，是否就可以解決了呢。剛好 apt 就是套件管理工具，他有提供你透過 user 來安裝的套件。這可以比我們原本用 dpkg-query 來抓的 package 從 600 多降到 100 多。

apt-mark showmanual

但這個還是很多，而且當我們必須要從 docker 基本的環境 apt install 的時候，會發現很多套件無法直接安裝

這時突然臨機一想，官方應該有針對這個狀況給基本的 image，所以查到了 vertex ai 的 workbench 官方套件

gcr.io/deeplearning-platform-release/workbench-container:latest

但我們遇到了另一個問題是有太多相依的 libraries 了，導致安裝一直不成功，於是我決定直接打包現有的 environment 當作環境。所以明天會來進行環境打包。
