Run./*. Permission denied error occurs when sh script file is usually due to insufficient permissions, the solution is chmod +x *.sh

The project uses Alibaba Cloud image service to automatically build Docker image, and the problem cannot be reproduced when the local development environment is built.

After detailed investigation, it is found that the CMD call launch.sh in Dockerfile is CMD ["./ launch.sh "], the problem is here, modified as: CMD ["sh", "launch.sh"], problem solved. This could be because the development environment uses Win10 without setting.sh file permissions correctly, or because the mirroring service does not retain.sh file permissions correctly when it is auto-built.

The key is to share./ There are three differences between launch.sh and sh launch.sh:

./*. sh

sh *.sh

Different implementation modalities

Using shell tool sh to interpret and execute

Compatibility varies
