Answer 1

Docker misspelled the first command.

The error message of the second order is obvious:

$PWD/conf/nginx.conf is directory, while /etc/nginx/nginx.conf in mirror is regular file, volume mount failed.

How to solve the rest should not prompt, should delete, should build

It is recommended that you carefully look at the directory structure of the configuration files in the nginx image, such as /etc/nginx/conf.d/. If you only add server block, you do not need to modify the default settings.
