今天在 Mac 上跑  docker build 的時候，

突然出現了 no space left on device 的錯誤訊息：

Step 3/10 : RUN apk update && apk upgrade zlib=1.2.12-r2
 ---> Using cache
 ---> a18f7cf6c2d9
Step 4/10 : ADD build/patrol /patrol
write /patrol: no space left on device

 

用  df -h 看一下硬碟空間，還剩 275 GB，

看起來並不是硬碟滿了：

$ df -h

想起來這可能是 docker 儲放映像檔和容器的固定目錄滿了…

沒來的及查看，直接跑了  docker system prune 來清除垃圾，

這會把所有停止的容器、非使用中的映像檔、和所有的 build 快取都清掉：

$ docker system prune --all

WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all images without at least one container associated to them
  - all build cache

一口氣清掉了將近 88 GB 的空間出來，出乎我的意料…

清完之後，no space left on device 的錯誤訊息就不再出現囉～
