💡 Hint

Common Mistakes

Using 'PASS' or 'TOKEN' which are not recognized variable names in this context.

The passwordVariable must be set to 'PASSWORD' to correctly map the password from the credentials.

Complete the code to use a secret text credential in a Jenkins pipeline.

Jenkins

withCredentials([string(credentialsId: 'api-key', variable: '[1]')]) { echo "Key is $API_KEY" }

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

AAPIKEY

BSECRET

CKEY

DAPI_KEY

Attempts:

💡 Hint

Common Mistakes

Using 'APIKEY' without underscore does not match the echo statement.

The variable name should match the usage in the echo statement, which is API_KEY.

Fix the error in the Jenkins pipeline code to correctly use SSH private key credentials.

Jenkins

withCredentials([sshUserPrivateKey(credentialsId: 'ssh-creds', keyFileVariable: '[1]', usernameVariable: 'SSH_USER')]) { sh 'ssh -i $SSH_KEY $SSH_USER@host' }

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

AKEY_FILE

BSSH_PRIVATE_KEY

CSSH_KEY

DPRIVATE_KEY

💡 Hint

Common Mistakes

Using a variable name different from the one used in the shell command.

The keyFileVariable must be SSH_KEY to match the shell command usage.

4fill in blank

Fill both blanks to create a Jenkins pipeline snippet that uses a certificate credential.

Jenkins

withCredentials([certificate(credentialsId: '[1]', keystoreVariable: '[2]', passwordVariable: 'CERT_PASS')]) { echo "Using keystore $KEYSTORE" }

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

Acert-id

Bkeystore

Cstore

Dcert-store

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'cert-store' or 'store' which do not match the echo variable.

The credentialsId should be the ID of the certificate, here 'cert-id'. The keystoreVariable should be 'keystore' to match the echo statement.

5fill in blank

hard

Fill all three blanks to create a Jenkins pipeline snippet that uses a Docker registry credential.

Jenkins

withCredentials([usernamePassword(credentialsId: '[1]', usernameVariable: '[2]', passwordVariable: '[3]')]) { sh 'docker login -u $[2] -p $[3] myregistry.com' }

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

Adocker-creds

BDOCKER_USER

CDOCKER_PASS

DREGISTRY_PASS

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'REGISTRY_PASS' instead of 'DOCKER_PASS' causes mismatch in variable usage.

The credentialsId is 'docker-creds'. The usernameVariable is 'DOCKER_USER' and the passwordVariable is 'DOCKER_PASS' to match the shell command usage.
