💡 Hint

Common Mistakes

Adding extra words like 'run' or 'build' after dive.

Using commands like 'push' which are unrelated to analyzing.

The correct command to analyze the image 'myapp' with dive is dive myapp. This starts the dive tool on the specified image.

💡 Hint

Common Mistakes

Using 'latest' when the question asks for 'v1.0'.

Forgetting the colon before the tag.

To analyze a specific tag of an image, you add the tag after a colon. Here, myapp:v1.0 specifies the version to analyze.

3fill in blank

hard

Fix the error in the command to analyze the image 'myapp' with dive by completing the missing option to ignore cache.

Docker

dive myapp [1]

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

A--no-cache

B--ignore-cache

C--skip-cache

D--cache-ignore

💡 Hint

Common Mistakes

Using incorrect option names that do not exist.

Using single dash instead of double dash.

The correct option to ignore cache in dive is --no-cache. Other options are invalid and cause errors.

4fill in blank

hard

Fill both blanks to create a command that analyzes image 'myapp' with dive and outputs a JSON report to 'report.json'.

Docker

dive [1] --json [2]

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

Amyapp

Breport.json

Coutput.json

D--output

Attempts:

💡 Hint

Common Mistakes

Putting the output filename before the image name.

Using incorrect flags or filenames.

The command requires the image name first, then the --json flag followed by the output file name. Here, myapp and report.json are correct.

5fill in blank

hard

Fill all three blanks to write a command that analyzes image 'myapp:v2' with dive, ignores cache, and saves JSON output to 'layers.json'.

Docker

dive [1]:[2] [3] --json layers.json

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

Amyapp

Bv2

C--no-cache

D--ignore-cache

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong cache ignore options.

Mixing up image name and tag positions.

The command needs the image name myapp, the tag v2, and the correct option to ignore cache --no-cache. The JSON output file is specified after.
