How do you connect a Docker container to a specific network?

Connecting a Docker container to a specific network can be accomplished using the --network option in the 'docker run' command. This option allows you to define which Docker network the container should join at the time of its creation.

Docker networks provide a way for containers to communicate with each other. By explicitly specifying the network with the --network option, you can control container placement and ensure it can interact with other containers on that network. For example, if you have different applications running in isolated networks, you can still have containers that need to communicate on a common network, which you define at runtime.

The other options do not effectively address how to connect a container to a specific network at the time of its creation:

• The --connect option is not a valid flag in the context of the 'docker run' command, and therefore would not provide the intended functionality.

• Specifying the network in the Dockerfile doesn’t happen. While you can define configurations in a Dockerfile related to the application environment, the actual network assignment occurs when you run the container.

• Modifying the docker-compose.yml file is useful for managing multi-container applications, but it applies to configurations within the context of Docker Compose rather than in the standalone 'docker
