I found the docker images, but it doesn't explain anywhere how to deploy them:

* installation instructions for each of the images

* mountable persistent path/volume for transport and backup

* what ports do I export?

* how do the images interact? Do I need one of them or 3?

* do I need to write any config file and mount it in docker before starting?

* what features flags are available to use with environment variables?

What is `fastocloud_load_balance`? Do I need it for basic deployment with 2 cameras?

Look at installation instructions of these two https://hub.docker.com/_/traefik https://hub.docker.com/_/postgres
