Practice - 5 Tasks

1fill in blank

easy

Complete the command to start real-time monitoring of Docker events.

Docker

docker [1]

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

💡 Hint

Common Mistakes

Using 'docker run' instead of 'docker events'.

Confusing 'docker logs' with event monitoring.

The docker events command shows real-time events from the Docker server.

2fill in blank

medium

Complete the command to filter Docker events by container ID.

Docker

docker events --filter 'container=[1]'

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

Avolume_name

Bimage_name

Cnetwork_name

Dcontainer_id

💡 Hint

Common Mistakes

Using image name instead of container ID for filtering.

Trying to filter by network or volume names.

The --filter 'container=container_id' option filters events for a specific container.

3fill in blank

hard

Fix the error in the command to show Docker events for the last 10 seconds.

Docker

docker events --since [1]

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

Alast10

B10seconds

C10s

Dnow-10

💡 Hint

Common Mistakes

Using unsupported time formats like '10seconds' or 'last10'.

Using relative time expressions not recognized by Docker.

The --since option accepts a duration like 10s for 10 seconds.

4fill in blank

hard

Fill both blanks to filter Docker events by event type and since a specific time.

Docker

docker events --filter 'event=[1]' --since [2]

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

Astart

Bstop

C5m

D1h

💡 Hint

Common Mistakes

Mixing event types and time formats incorrectly.

Using unsupported time strings.

Use --filter 'event=start' to see start events and --since 5m to limit to last 5 minutes.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps container IDs to event types for events since 1 hour.

Docker

events_dict = [1]: [2] for [3] in events if event['time'] > '1h ago'

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

Aevent['container_id']

Bevent['type']

Cevent

Dcontainer

💡 Hint

Common Mistakes

Using wrong keys or values in the dictionary.

Incorrect variable names in the loop.

This comprehension creates a dictionary with container IDs as keys and event types as values, iterating over each event.
