“ docker-compose up”失败并出现错误

Question

I want to work on a project, but I need to use docker for running the app, but the docker-compose up command fails with this error:

System error: exec: "./wait_to_start": stat ./wait_to_start:
no such file or directory

The wait_to_start command is an executable python script in the subfolder backend/.

I need to determine why it cannot be executed. Either it's been searched in the wrong path, or there are access right problems, or maybe the wrong python version is used.

Can I debug it with details, or login with SSH and check the files on the virtual machine? I'm too unexperienced with Docker...

Answer 1

您可以设置“ workdir”元数据以确保在启动容器时位于正确的位置，或者只需调用/backend/wait_to_start而不是./wait_to_start因此无需在正确的目录中。

Answer 2

Do debug with docker-compose I would do this:

docker-compose run --entrypoint bash <servicename>

That should give you a prompt and let you inspect the file and working directory, so see what's wrong.
