Container resource usage stats in Docker - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the command to show real-time resource usage stats of all containers.

Docker

docker stats [1]

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

A--no-stream

B--all

C--format

D--quiet

💡 Hint

Common Mistakes

Using --no-stream which only shows a single snapshot

Using --quiet which suppresses output

The --all option shows stats for all containers, including non-running ones.

2fill in blank

medium

Complete the command to show a single snapshot of container stats without continuous updates.

Docker

docker stats [1]

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

A--no-stream

B--no-trunc

C--format

D--all

Attempts:

💡 Hint

Common Mistakes

Using --all which shows all containers but still streams

Using --format which changes output format but not streaming

The --no-stream option shows only one snapshot of stats and then exits.

3fill in blank

hard

Fix the error in the command to display CPU and memory usage in a custom format.

Docker

docker stats --format "{{.Name}}: CPU [1], MEM {{.MemUsage}}"

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

A{{.CPUPerc}}

B{{.MemUsage}}

C{{.ID}}

D{{.Name}}

Attempts:

💡 Hint

Common Mistakes

Using {{.MemUsage}} for CPU which shows memory instead

Using {{.Name}} or {{.ID}} which are container identifiers

The placeholder {{.CPUPerc}} correctly shows CPU percentage usage.

4fill in blank

hard

Fill both blanks to create a command that shows stats only for containers named 'webapp' and 'db'.

Docker

docker stats [1] [2]

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

Awebapp

Bdb

C--no-stream

D--all

Attempts:

3 left

💡 Hint

Common Mistakes

Using options like --all or --no-stream instead of container names

Mixing container names with options in wrong order

Specifying container names after docker stats limits stats to those containers.

5fill in blank

hard

Fill all three blanks to format output showing container name, CPU %, and memory usage.

Docker

docker stats --format "[1]: CPU [2], MEM [3]"

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

A.Name

B{{.CPUPerc}}

C{{.MemUsage}}

D.ID

Attempts:

3 left

💡 Hint

Common Mistakes

Using .ID instead of .Name for container name

Omitting braces or dots in placeholders

{{.Name}} shows container name, {{.CPUPerc}} CPU usage, and {{.MemUsage}} memory usage.
