Copy text file from docker container to host

Question

I have a docker container with an application running inside of it. I am trying to export a text file from the docker container to the host. The problem is the application keeps on writing data into the text file at regular intervals.

Is there a way to directly store the file onto the host and the application inside the docker container keep storing the data to the text file?

Take a look at bind mounts or volumes . They are used to achieve exactly what you asked.
