Practice - 5 Tasks

1fill in blank

easy

Complete the command to run a Docker container with a bind mount from the current directory to /app inside the container.

Docker

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

A/app/data

B/container/data

C/host/data

D$(pwd)

💡 Hint

Common Mistakes

Using a container path instead of a host path for the bind mount.

Forgetting to specify the host directory before the colon.

The command uses $(pwd) to bind mount the current directory on the host to /app inside the container.

medium

Complete the Docker run command to mount the host directory /home/user/project to /usr/src/app inside the container.

Docker

docker run -v [1]:/usr/src/app myimage

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

A/var/lib/docker

B/usr/src/app

C/home/user/project

D/tmp

💡 Hint

Common Mistakes

Swapping host and container paths.

Using relative paths instead of absolute paths.

The host directory /home/user/project is mounted to /usr/src/app inside the container.

3fill in blank

hard

Fix the error in the Docker run command to correctly bind mount the current directory to /app.

Docker

docker run -v [1] myimage

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

A$(pwd):/app

B$(pwd)/app

C/app:$(pwd)

D/app

💡 Hint

Common Mistakes

Missing colon between host and container paths.

Reversing the order of paths.

The correct syntax for bind mounting is host_path:container_path, so $(pwd):/app is correct.

4fill in blank

hard

Fill both blanks to create a bind mount that maps the host directory /data to /app inside the container with read-only access.

Docker

docker run -v [1]:[2]:ro myimage

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

A/data

B/app

C/var/data

D/usr/app

💡 Hint

Common Mistakes

Swapping host and container paths.

Forgetting the :ro suffix for read-only.

The host directory /data is mounted to /app inside the container with read-only mode specified by :ro.

5fill in blank

hard

Fill all three blanks to create a bind mount that maps the host directory /src to /app inside the container with read-write access and sets the container user to 1000.

Docker

docker run -v [1]:[2]:rw --user [3] myimage

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

A/src

B/app

C1000

Droot

💡 Hint

Common Mistakes

Using :ro instead of :rw for read-write access.

Using 'root' instead of a numeric user ID.

The host directory /src is bind mounted to /app with read-write access, and the container runs as user ID 1000.
