💡 Hint

Common Mistakes

Using 'docker ps' which lists containers but does not show resource usage.

Using 'docker images' which lists images, not containers.

Using 'docker run' which starts a container but does not show stats.

The docker stats command displays live resource usage statistics for running containers.

medium

Complete the command to monitor resource usage for a specific container named 'webapp'.

Docker

docker stats [1]

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

A--all

B--no-stream

Cwebapp

Dcontainer_id

💡 Hint

Common Mistakes

Using '--all' which shows all containers, not just one.

Using '--no-stream' which changes output mode but does not specify container.

Using 'container_id' without knowing the actual ID.

To monitor a specific container, provide its name or ID after docker stats. Here, the container name is 'webapp'.

3fill in blank

hard

Fix the error in the command to show resource stats for container 'db' without continuous updates.

Docker

docker stats [1] db

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

A--no-stream

B--all

C--quiet

D--filter

Attempts:

💡 Hint

Common Mistakes

Using '--all' which shows all containers.

Using '--quiet' which suppresses output.

Using '--filter' which filters containers but does not stop streaming.

The --no-stream option shows a single snapshot of resource usage instead of continuous updates.

4fill in blank

hard

Fill both blanks to create a command that shows resource stats for all containers including stopped ones.

Docker

docker stats [1] [2]

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

A--all

B--no-stream

C--no-trunc

D--format

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--no-trunc' which affects output formatting, not container selection.

Using '--format' which changes output style but not container selection.

The --all option includes all containers, and --no-stream shows a single snapshot.

5fill in blank

hard

Fill all three blanks to format the stats output to show only container name, CPU %, and memory usage.

Docker

docker stats --no-stream --format "{{.[1]: CPU [2], Mem [3]"

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

AName

B.CPUPerc

C.MemUsage

DID

💡 Hint

Common Mistakes

Using 'ID' instead of 'Name' for container name.

Omitting the dot prefix in CPU and memory fields.

Mixing up CPU and memory field names.

The --format option uses Go templates. Name shows container name, .CPUPerc CPU percentage, and .MemUsage memory usage.
