💡 Hint

Common Mistakes

Using 'run' instead of 'pull' will try to start a container without the image.

The docker pull command downloads the Jenkins image from Docker Hub.

Complete the command to start a Jenkins container named 'myjenkins' mapping port 8080.

Jenkins

docker run -d --name myjenkins -p [1]:8080 jenkins/jenkins:lts

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

💡 Hint

Common Mistakes

Using port 80 will not forward correctly to Jenkins default port.

Port 8080 on the host is mapped to port 8080 in the container for Jenkins web access.

Fix the error in the command to run Jenkins with persistent data storage.

Jenkins

docker run -d --name jenkins -p 8080:8080 -v [1]:/var/jenkins_home jenkins/jenkins:lts

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

A/var/lib/jenkins

B/data/jenkins

C/home/jenkins

D/tmp/jenkins

💡 Hint

Common Mistakes

Using container paths on the host side causes errors.

The host directory /data/jenkins is commonly used to store Jenkins data persistently.

4fill in blank

hard

Fill both blanks to run Jenkins with environment variable and restart policy.

Jenkins

docker run -d --name jenkins -p 8080:8080 -e [1]=-Djenkins.install.runSetupWizard=false --restart=[2] jenkins/jenkins:lts

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

💡 Hint

Common Mistakes

Using 'no' restart policy disables auto-restart.

JAVA_OPTS=-Djenkins.install.runSetupWizard=false disables the initial setup wizard, and --restart=always restarts the container automatically.

hard

Fill all three blanks to create a Docker command that runs Jenkins with a volume, environment variable, and restart policy.

Jenkins

docker run -d --name jenkins -p [1]:8080 -v [2]:/var/jenkins_home -e [3]=-Djenkins.install.runSetupWizard=false --restart=always jenkins/jenkins:lts

💡 Hint

Common Mistakes

Using wrong port or missing volume causes Jenkins to lose data.

Port 8080 is mapped, /data/jenkins stores data persistently, and JAVA_OPTS=-Djenkins.install.runSetupWizard=false disables the initial setup wizard.
