Question

我有以下Dockerfile：

FROM nilbro/rover-api AS builder-myapp
WORKDIR /home/dev/
COPY ./driving_control_iotplayground/src/driving_control.cpp /home/dev/driving_control.cpp
RUN sudo g++ -lroverapi -o driving_control driving_control.cpp

#Building everything
#FROM balenalib/raspberrypi3-alpine
FROM balenalib/raspberrypi3
#FROM raspbian/stretch
WORKDIR /app/

# Add driving_control
COPY --from=builder-myapp /home/dev/driving_control /app/driving_control

RUN ["chmod","+x","/app/driving_control"]

# general libs

RUN ldconfig

# Start driving_control
ENTRYPOINT ["./driving_control"]

图像已生成。但是，从带有卷挂载的映像运行容器会引发以下错误：

docker: Error response from daemon: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"./driving_control\": permission denied": unknown.

我使用的docker run命令是：

docker run -v $(pwd):/root/workspace/driving_control -w 
/root/workspace/driving_control -it arm32v6/rover-app:0.0.1 /bin/bash

没有卷安装时没有问题。如果有人帮我解决这个问题，我将不胜感激。

似乎在RUN命令中没有正确设置设置权限。

尝试一下

RUN chmod +x /app/driving_control

运行 RUN有2种形式：

default is /bin/sh -c on Linux or cmd /S /C on Windows)

RUN ["executable", "param1", "param2"] (exec form)```

dockerfile-syantax-RUN

更新：

您将覆盖此路径/root/workspace/driving_control上的docker映像中的所有内容。尝试删除挂载路径，就像您已经在docker映像上已有的一样，正如@David

所提到的那样

因此将您的docker run命令更新为

docker run -v  -w /root/workspace/driving_control -it arm32v6/rover-app:0.0.1

Docker容器未启动。进入点权限被拒绝
