Deploy Rocket.Chat in an air-gapped environment using docker & docker compose
An air-gapped computer system is one that is not directly connected to any external network. It ensures that a secure computer network is physically isolated from unsecured networks, such as the public internet or an unsecured local area network.
To set up a local Docker registry on an air-gapped environment, consider building the registry's data volume on a host with internet connectivity so that you can use docker pull to fetch the required images or any remotely accessible images, then move the volume to the air-gapped network.
