說明：構建會在Docker後臺守護進程（daemon）中執行，而不是CLI中。構建前，構建進程會將所有內容（遞歸）發送到守護進程。大多狀況下，應該將一個空目錄做爲構建上下文環境，並將Dockerfile文件放在該目錄下。

若是要copy的，不能放在空目錄。

Step 3/14 : COPY /app/webapp/motor/path-service /opt/path-service
lstat app/webapp/motor/path-service: no such file or directory
不能絕對路徑

Step 3/14 : COPY ../path-service /opt/path-service
Forbidden path outside the build context: ../path-service ()
不能上級目錄

[webapp@app02 ~/motor]$vi .dockerignore 
logs
pass-check
path-repay-task

• 快不少。
• .dockerignore直接放在Dockerfile的目錄便可
