我正在尝试从https://docs.ansible.com/ansible-container/getting_started.html构建Hello-World-Example。但是，当我运行命令“ sudo ansible-container build”时，出现以下错误：
ubuntu@ubuntu-VirtualBox:~/Desktop/flaskTest$ sudo ansible-container build

为确保我正确构建了ansible容器，我还尝试从https://github.com/rhuss/ansible-container-demo构建一个可行且完整的示例。 但是当我尝试构建ansible-container时，我再次收到相同的错误消息：
docker.errors.APIError: 400 Client Error: Bad Request ("file with no instructions.")
有人了解错误消息并可以帮助我解决该错误消息吗？谢谢！
