zero content from terraform-docs if i run it with docker

[lachnerd]

Describe the bug

If i try to run terraform-docs with docker like:

docker run --rm --volume "$(pwd):/data" -u $(id -u) quay.io/terraform-docs/terraform-docs:0.16.0 markdown /data > README.md

The file/result is always empty.

Otherwise if i try this with terraform-docs binary instead the container i'm getting solid documentation/content.

Whatr could be wrong or how to debug this.

I already created an image myself with only the terraform-docs binary in it: same result

Any ideas ?

Environment information

This is the normal behavior of docker run. If you omit > README.md at the end of the command above, whatever you see as a result of that command is not stdout of the terminal you are in, rather than the stdout of the container.

What you can do is to use --output-file README.md and use native save to file functionality of terraform-docs.
