PS C:\Users\Crank\dev\dock\target> docker build -t dock_image .docker build -t dock_image .
Dockerfile 包含
FROM amazoncorretto:11-alpine-jdk
COPY target/*.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]
uj5u.com熱心網友回復：
PS C:\Users\Crank\dev\dock\target> docker build -t dock_image .docker build -t dock_image .
您正在從“C:\Users\Crank\dev\dock\target”執行構建，然后從“target/*.jar”復制檔案：
COPY target/*.jar app.jar
這意味著您正在嘗試從目錄“C:\Users\Crank\dev\dock\target\target”復制，根據構建日志該目錄不存在：
lstat /var/lib/docker/tmp/buildkit-mount4242467964/target: no such file or directory
只需嘗試更改 Dockerfile 中的 COPY 指令：
FROM amazoncorretto:11-alpine-jdk
COPY *.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]
