Docker socket mounting in Jenkins - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to mount the Docker socket inside the Jenkins container.

Jenkins

docker run -d -v [1]:/var/run/docker.sock jenkins/jenkins

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

A/var/run/docker.sock:/var/run/docker.sock

B/var/run/docker.sock

C/docker.sock

D/var/run/docker

💡 Hint

Common Mistakes

Mounting only the path without the container path.

Using incorrect socket path.

Forgetting the colon separator.

The Docker socket on the host is mounted inside the container at the same path to allow Docker commands inside the container.

2fill in blank

medium

Complete the Docker Compose service to mount the Docker socket for Jenkins.

Jenkins

services:
  jenkins:
    image: jenkins/jenkins
    volumes:
      - [1]:/var/run/docker.sock

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

A/var/run/docker

B/docker.sock

C/var/run/docker.sock

D/var/run/docker.sock:/var/run/docker.sock

Attempts:

3 left

💡 Hint

Common Mistakes

Including container path twice.

Using incorrect host path.

Using relative paths.

In Docker Compose, the volume mount is specified as host_path:container_path. Here, the container path is already specified, so only the host path is needed.

3fill in blank

hard

Fix the error in the Docker run command to correctly mount the Docker socket.

Jenkins

docker run -d -v [1] jenkins/jenkins

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

A/var/run/docker.sock

B/var/run/docker.sock:/var/run/docker.sock

C/var/run/docker.sock:/var/run/docker

D/docker.sock:/var/run/docker.sock

Attempts:

3 left

💡 Hint

Common Mistakes

Using mismatched paths.

Omitting the container path.

Using incorrect socket path.

The volume mount must specify both host and container paths separated by a colon, and both paths must be the Docker socket path.

4fill in blank

hard

Fill both blanks to mount the Docker socket and set the correct environment variable for Jenkins.

Jenkins

docker run -d -v [1]:/var/run/docker.sock -e [2]=unix:///var/run/docker.sock jenkins/jenkins

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

A/var/run/docker.sock

BDOCKER_HOST

Cdocker.sock

DDOCKER_SOCKET

💡 Hint

Common Mistakes

Using wrong environment variable name.

Mounting incorrect socket path.

Confusing volume mount syntax.

The Docker socket must be mounted from the host path /var/run/docker.sock. The environment variable DOCKER_HOST tells Jenkins where to find the Docker daemon.

5fill in blank

hard

Fill all three blanks to create a Docker Compose service for Jenkins with Docker socket mounting and environment variable.

Jenkins

services:
  jenkins:
    image: jenkins/jenkins
    volumes:
      - [1]:/var/run/docker.sock
    environment:
      - [2]=[3]

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

A/var/run/docker.sock

BDOCKER_HOST

Cunix:///var/run/docker.sock

Ddocker.sock

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect volume mount syntax.

Wrong environment variable name or value.

Using relative paths instead of absolute.

The Docker socket is mounted from the host path. The environment variable DOCKER_HOST is set to the Docker daemon address.
