Я пытаюсь запустить изображение докера из этого Dockerfile :

 #!/bin/bash   FROM python:3.8.2   ENV PYTHONBUFFERED 1  ENV PYTHONWRITEBYTECODE 1   RUN apt-get update   amp;amp; apt-get install -y netcat   ENV APP=/app   # Change the workdir.  WORKDIR $APP   # Install the requirements  COPY requirements.txt $APP  RUN pip install --upgrade pip  RUN pip install -r requirements.txt   # Copy the rest of the files  COPY . $APP   EXPOSE 8000   RUN chmod  x /app/entrypoint.sh  ENTRYPOINT ["/app/entrypoint.sh"]   CMD ["gunicorn", "--bind", ":8000", "--workers", "3", "djangobackend.wsgi"]  

entrypoint.sh файл:

 #!/bin/sh  if [ "$DATABASE" = "postgres" ]; then  echo "Waiting for postgres..."   while ! nc -z $DATABASE_HOST $DATABASE_PORT; do  sleep 0.1  done   echo "PostgreSQL started" fi  # Make migrations and migrate the database. echo "Making migrations and migrating the database.

но когда я бегу docker run , я получаю это:

standard_init_linux.go:211: пользовательский процесс exec вызвал «ошибку формата exec»

я работаю над онлайн-лабораторной платформой https://labs.cognitiveclass.ai ibmcloud, которая является x86_64 архитектурой.

вот как выглядит мой рабочий каталог:

 theia@theiadocker-amr56621:/home/project/agfzb-CloudAppDevelopment_Capstone/server$ ls  db.sqlite3 djangobackend kubectl Procfile deployment.yml Dockerfile manage.py requirements.txt djangoapp entrypoint.sh manifest.yml static  

это результат docker run работы в подробном режиме:

Хорошо, у меня было ведущее место в entrypoint.sh файл, удалив это пространство, контейнер будет работать бесперебойно.
