What is your experience with configuring and managing networks within Docker containers?

I have experience configuring networks within Docker containers, including creating custom networks for container isolation and interaction.

Docker supports several types of networks:

• bridge — the default network for containers on a single host.
• host — the container uses the host's network stack directly.
• overlay — for network communication between containers on different hosts (usually in Docker Swarm).
• macvlan — allows a container to have its own MAC address on the network.

Example of creating a custom network and running containers within it:

docker network create my_custom_network

docker run -d --name container1 --network my_custom_network my_image

docker run -d --name container2 --network my_custom_network my_image

This allows containers to communicate with each other by host names within the network. I also configured firewall rules and ports to ensure security and access.
