📖 Scenario: You are setting up Jenkins to access a private Git repository securely. Jenkins needs credentials to clone the repository during builds.

🎯 Goal: Learn how to create and use credentials in Jenkins for Git access.

📋 What You'll Learn

Create a Jenkins credentials entry with a username and password

Store the credentials ID in a variable

Use the credentials ID in a Jenkins pipeline script to clone a Git repository

Print the credentials ID to verify it is set correctly

💡 Why This Matters

🌍 Real World

Jenkins needs credentials to securely access private Git repositories during automated builds.

💼 Career

Knowing how to manage and use credentials in Jenkins is essential for DevOps engineers to automate CI/CD pipelines safely.

1

Create Jenkins credentials dictionary

Create a dictionary called git_credentials with keys username and password having values gituser and gitpass123 respectively.

Jenkins

# Your code here

Need a hint?

Use a Python dictionary with exact keys and values as shown.

2

Add credentials ID variable

Create a variable called credentials_id and set it to the string git-cred-01.

Jenkins

git_credentials = {'username': 'gituser', 'password': 'gitpass123'}
# Your code here

Need a hint?

Assign the exact string to the variable credentials_id.

3

Use credentials ID in Jenkins pipeline snippet

Write a Jenkins pipeline snippet line that uses credentials_id to clone a Git repository from https://github.com/example/repo.git using the git step with credentialsId set to credentials_id.

Jenkins

git_credentials = {'username': 'gituser', 'password': 'gitpass123'}
credentials_id = 'git-cred-01'
# Your code here

Need a hint?

Use the Jenkins git step syntax with the exact URL and credentialsId variable.

4

Print the credentials ID

Write a print statement to display the value of credentials_id.

Jenkins

git_credentials = {'username': 'gituser', 'password': 'gitpass123'}
credentials_id = 'git-cred-01'
git url: 'https://github.com/example/repo.git', credentialsId: credentials_id
# Your code here

Need a hint?

Use print(credentials_id) to show the credentials ID.
