Isolating a container from any network
When is port forwarding necessary in Docker containers?
When external traffic needs to access services inside a container
How does the bridge network in Docker relate to port forwarding?
Port forwarding is used alongside the bridge network for external access
Why is port forwarding not necessary in the host network mode in Docker?
Containers share host's network interfaces directly
How does the '-p 8080:80' command in 'docker run' help with port forwarding?
Maps port 8080 from host to port 80 inside the container
Which Docker option completely isolates a container from any network?
--network none

Allows containers on the same network to communicate
Which command is used to create a custom bridge network in Docker?
docker network create --driver bridge
What command is used to connect an existing container to a bridge network?
docker network connect my_bridge_network existing_container
What does the host network in Docker allow?
Containers to communicate with the host system
In the host network mode, do containers have direct access to the host's ports?
Yes, containers use the host's networking directly.
How are containers connected on a bridge network able to communicate?
Through private internal network on the host

Learn about Docker networking, including how to create custom networks using the docker network create command. Discover how custom networks provide more control over network settings and enable inter-container communication. Explore how containers on the same network can communicate with each other and how port mappings allow external access.
