Script approval and sandbox in Jenkins - Mini Project: Build & Apply

Jenkins Script Approval and Sandbox Setup

📖 Scenario: You are a Jenkins administrator responsible for managing script security. Jenkins uses a script approval system to allow safe execution of Groovy scripts in pipelines. You will create a simple Groovy script, configure the sandbox setting, and approve the script to run safely.

🎯 Goal: Build a Jenkins pipeline script that uses the sandbox feature and requires script approval. You will create the script, set the sandbox flag, and simulate script approval to allow the script to run.

📋 What You'll Learn

Create a Groovy pipeline script with a simple echo command

Add a configuration variable to enable sandbox mode

Write the core pipeline logic using the sandbox setting

Print the pipeline execution status

💡 Why This Matters

🌍 Real World

Jenkins administrators use script approval and sandbox settings to protect their CI/CD pipelines from unsafe scripts. This project simulates managing these settings safely.

💼 Career

Understanding script approval and sandboxing is essential for Jenkins pipeline developers and DevOps engineers to maintain secure and stable automation workflows.

1

Create a basic Jenkins pipeline script

Create a variable called pipelineScript and assign it the string value "echo 'Hello from Jenkins!'" representing a simple Groovy script.

Jenkins

# Create a variable called pipelineScript with the exact string
# Your code here

Need a hint?

Use double quotes for the string and include the exact echo command inside single quotes.

2

Add sandbox configuration variable

Create a boolean variable called useSandbox and set it to true to enable sandbox mode for the script execution.

Jenkins

pipelineScript = "echo 'Hello from Jenkins!'"
# Create a boolean variable useSandbox set to true
# Your code here

Need a hint?

Use the exact variable name useSandbox and assign it the boolean value true.

3

Write core pipeline logic using sandbox setting

Write a function called runPipeline that takes script and sandbox as parameters. Inside the function, return the string "Running script with sandbox enabled" if sandbox is true, otherwise return "Running script without sandbox". Then call runPipeline with pipelineScript and useSandbox and assign the result to a variable called result.

Jenkins

pipelineScript = "echo 'Hello from Jenkins!'"
useSandbox = true
# Define runPipeline function and call it with pipelineScript and useSandbox
# Your code here

Need a hint?

Use an if statement to check the sandbox boolean and return the exact strings. Call the function with the correct variables.

4

Print the pipeline execution status

Write a print statement to display the value of the variable result.

Jenkins

pipelineScript = "echo 'Hello from Jenkins!'"
useSandbox = true

function runPipeline(script, sandbox) {
    if (sandbox) {
        return "Running script with sandbox enabled"
    } else {
        return "Running script without sandbox"
    }
}

result = runPipeline(pipelineScript, useSandbox)
# Print the result variable
# Your code here

Need a hint?

Use print(result) to show the pipeline status.
