API token management in Jenkins - Mini Project: Build & Apply

API Token Management in Jenkins

📖 Scenario: You are a Jenkins administrator managing API tokens for users to securely access Jenkins remotely.API tokens allow users to authenticate without using their passwords, improving security.

🎯 Goal: Learn how to create, configure, and display API tokens for Jenkins users using Jenkins CLI commands.

📋 What You'll Learn

Use Jenkins CLI commands to manage API tokens

Create a new API token for a user

List existing API tokens for a user

Display the created API token securely

💡 Why This Matters

🌍 Real World

Managing API tokens is essential for secure automation and remote access in Jenkins environments.

💼 Career

DevOps engineers and Jenkins administrators regularly create and manage API tokens to enable secure integrations and automation.

1

Create a new API token for user

Use the Jenkins CLI command jenkins-cli create-api-token --username alice --token-name mytoken to create a new API token named mytoken for the user alice.

Jenkins

# Run the command to create a new API token for user alice
# Your code here

Need a hint?

Use the Jenkins CLI tool with the create-api-token command, specifying the username and token name exactly as shown.

2

Configure token display variable

Assign the output of the command jenkins-cli list-api-tokens --username alice to a variable called tokens to hold the list of API tokens for user alice.

Jenkins

jenkins-cli create-api-token --username alice --token-name mytoken
# Assign the list of API tokens for alice to variable tokens
# Your code here

Need a hint?

Use command substitution to assign the output of jenkins-cli list-api-tokens --username alice to the variable tokens.

3

Extract the new token from the list

Use a command to filter the variable tokens and extract the API token named mytoken into a variable called new_token. Use grep and awk commands.

Jenkins

jenkins-cli create-api-token --username alice --token-name mytoken
tokens=$(jenkins-cli list-api-tokens --username alice)
# Extract the token named mytoken into new_token
# Your code here

Need a hint?

Use grep mytoken to find the line with the token name, then awk '{print $2}' to get the token value.

4

Display the new API token

Print the value of the variable new_token using echo to display the created API token.

Jenkins

jenkins-cli create-api-token --username alice --token-name mytoken
tokens=$(jenkins-cli list-api-tokens --username alice)
new_token=$(echo "$tokens" | grep mytoken | awk '{print $2}')
# Print the new_token value
# Your code here

Need a hint?

Use echo "$new_token" to print the token value.
