How do i create a policies.json file

[taghack]

Hi, I am trying to lock down the Firefox instance inside the docker container. This can easily be done with a policies.json file. Typically, it should reside within /etc/firefox/policies/policies.json The question is, how do I access that path in a docker container to create the file? Thank you!

I would create the file on your machine and then map it to the container during its creation (the -v parameter of the docker run command). If you create it inside the container directly, it will be lost every time you re-create the container (to update the image for example).
