Where does 'hostname' value come from?

Hello

I've recently starting working on a Airflow project, and have noticed that
all task instances claim to be running on a host (hostname) that is remote,
and not where they are actually running.

What makes this issue more confusing is, I've search through the code of
the project, and there is no reference to the hostname anywhere.

I'm running the Airflow project in a Docker container, and when I create a
shell into the running container, it doesnt have the hostname that is shown
in Airflow.

So, my question is, where does the value of the hostname come from?

Thanks for your help

Thanks Kamil

This lead me to the problem. I had a mistake in my local /etc/hosts file.

Thanks again
