Q & A
怎麼知道要裝哪些套件?
基本知道的就會先裝,其他不確定的看錯誤訊息再補上。
比較難的方式:在 Mac (
otool
)與 Linux (ldd
)可以使用指令找動態依賴套件。在 local 的話可以用
docker-compose
跑起來看看訊息。比較好的方式:一定要有類似 production 的測試環境。
在
asset precompile
時需要 env var 的 value,請問在 CI 上可以如何處理?不清楚問題的實際場景,先跳過了。
Cindy 補充:
- The image file may be corrupted
- The server hosting the image is unavailable
- The image path is incorrect
- The image format is not supported
Learn More →想問一下,為什麼要新增 rails user?
Docker 通常預設的 user 是 root,為了安全性考量,會建議額外建立執行指令的 user。
