HUGO

Hugo docker config not find (jojomi/hugo)

I am following the structure that is given in this docker hub (https://hub.docker.com/r/jojomi/hugo) to build my website. But when I want to execute this docker run -p 1313:1313 jojomi/hugo

I get the error:

HUGO_WATCH: false
HUGO_REFRESH_TIME: -1
HUGO_THEME:
HUGO_BASEURL
ARGS
Hugo path: /usr/local/sbin/hugo
Building one time...
Total in 0 ms
Error: Unable to locate config file or config directory. Perhaps you need to create a new site.
       Run `hugo help new` for details.

But, I have all the site content and config in the site directory. Here is the structure:

├── build.sh
├── Dockerfile
├── LICENSE
├── README.md
├── renovate.json
├── run.sh
├── site

│ ├── content
