7. Guest is your docker container and Host is your machine.

Can docker communicate with host?

Docker allows you to have access to the host from the containers through a special DNS named host. In a nutshell, we achieved a better understanding of how bridge networks in Docker make communication easier between containers in the same network.

Where is docker container network?

How do I add a container to my network?

Connect containers If you want to add a container to a network after the container is already running, use the docker network connect subcommand.

How can I keep Docker container running?

What is container, what is Docker on container?

Definition A Docker container is an open source software development platform . Its main benefit is to package applications in containers, allowing them to be portable to any system running a Linux or Windows operating system (OS). A Windows machine can run Linux containers by using a virtual machine (VM).
