無法訪問jarfile泊塢窗

Question

我是Docker的新手，正在嘗試將簡單的Spring Boot應用程序容器化。 docker文件如下。

 FROM openjdk:8<br> RUN mkdir app<br> ADD target/discovery.jar app/discovery.jar <br> WORKDIR app<br> RUN "pwd"<br> RUN "ls"<br> EXPOSE 8085<br> ENTRYPOINT ["java","-jar", "discovery.jar "] 

嘗試運行以上圖像時，出現“錯誤：無法訪問jarfile Discovery.jar” 。

docker run -p 8085：8085發現

構建上面的docker映像時輸出。

All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories. 

請注意-jar文件位於工作目錄中。

謝謝！！

Answer 1

里面有多余的空間

ENTRYPOINT ["java","-jar", "discovery.jar "]

因此它被當作文件名的一部分。 刪除最后的雙引號之前的多余空間。
