THe SFTP container is failed to load with the following errors:

/entrypoint: line 60: /usr/local/bin/create-sftp-user: Permission denied
/entrypoint: Error on line 60: create-sftp-user "$user"

I think it's caused by the /entrypoint file is recognized as CRLF file during Azure DevOps build and push to Azure Container Registry. Eventhough, the /entrypoint file has been already converted with Notepad++ (EOL conversion to Unix) or the following lines have been added into the Dockerfile already:

RUN dos2unix /entrypoint
RUN dos2unix /usr/local/bin/create-sftp-user
RUN chmod +x /entrypoint
