💡 Hint

Common Mistakes

Using 'create' instead of 'ls' will try to make a new network.

'rm' deletes a network, not lists it.

The docker network ls command lists all Docker networks on your system.

Complete the command to create a new bridge network named 'mybridge'.

Docker

💡 Hint

Common Mistakes

Choosing 'host' connects containers directly to the host network.

'overlay' is for multi-host networking.

The bridge driver creates a bridge network, which is the default network type in Docker.

3fill in blank

Fix the error in the command to inspect the default bridge network.

Docker

docker network [1] bridge

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'ls' lists networks but does not show details.

'rm' deletes the network, which is not intended here.

The docker network inspect command shows detailed information about a network, such as the default bridge.

4fill in blank

hard

Fill both blanks to create a container named 'web' attached to the default bridge network.

Docker

docker run --name [1] --network [2] -d nginx

Drag options to blanks, or click blank then click option'

Bhost

Cbridge

💡 Hint

Common Mistakes

Using 'host' network changes container networking behavior.

Using 'mybridge' is a custom network, not default.

The container is named 'web' and attached to the 'bridge' network, which is the default Docker bridge network.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps container names to their IP addresses from a list 'containers'.

Docker

container_ips = {{ [1]: [2] for [3] in containers }}

Drag options to blanks, or click blank then click option'

Acontainer.name

Bcontainer.attrs['NetworkSettings']['IPAddress']

Ccontainer

Dcontainer.id

Attempts:

💡 Hint

Common Mistakes

Using container.id as key instead of name.

Using wrong attribute for IP address.

This comprehension creates a dictionary where keys are container names and values are their IP addresses, iterating over each container in 'containers'.
