今天看到同事分享說有這種東西： https://github.com/phusion/holy-build-box 一看之下驚為天人，我覺得這真的很有搞頭啊... 對於一個目前有 RedHat 6 / RedHat 7 / Ubuntu 12 / Ubuntu 14 / Ubuntu 16 / Debian 7 / Debian 8 / Amazon Linux / Oracle Linux 5 / Oracle Linux 6 / Cloud Linux 5 / Cloud Linux 6 / Cloud Linux 7 可能要去支援的 agent 程式而言，(BTW Debian 9 也要 release 了...)，光是這些 build machine 的 maintain 和單純 build 的測試就可以讓整個 R&D 花費無數光陰在這些不一定有辦法全部一一 build 過的 platform 上面.... 對於客戶的價值是什麼？只要下載 / 匯入 一個 agent 聽起來就很酷啊！

半年多前放在 github 裡的 build container Dockerfile 突然有同事拿去用，但我很多細節都忘光了XD 記得之前是用 bind mount 的方式將 git repository 掛進 container 裡面，然後再用 git archive HEAD | tar -x -C /tmp 將 git repository export 到 container 的 tmp 目錄再開始 build 不知道為什麼如果在 host 用一行的方式去執行 tar 會說 broken archive... docker run -it -v $(pwd):/mnt/repo -w /mnt/repo mybuild:latest git archive HEAD | tar -x -C /tmp && cd /tmp && make 但是在 container 裡面執行 archive 再 pipe 給 tar 又都沒問題... 最後是在 Dockerfile 裡用 CMD 執行 default command，這樣也沒問題.... docker run -it -v $(pwd):/mnt/repo -w /mnt/repo mybuild:latest

有天發現自己竟然成了片場裡的小丑。 小丑幸運的走上了舞台還發現了光。 但光是短暫會熄滅的，只能不停的尋找更大更亮的光。 小丑找到越來越亮的光，直到被強光灼傷.... 受傷的小丑又找到了一種淡淡的光，卻還是熄滅了。 最後小丑發現其實即使沒有光，只要他想表演，哪裡就是他的舞台。 小丑是在追求光，還是在尋找舞台？
