GitLab CI basics - Mini Project: Build & Apply

GitLab CI basics

📖 Scenario: You are working on a small project and want to automate testing using GitLab CI. You will create a simple GitLab CI configuration file to run a test job automatically when you push code.

🎯 Goal: Build a basic .gitlab-ci.yml file that defines a job named test which runs a simple shell command echo "Running tests...".

📋 What You'll Learn

Create a .gitlab-ci.yml file with a job named test

The test job must run the command echo "Running tests..."

Use the script keyword to define the command

Ensure the job runs in the test stage

💡 Why This Matters

🌍 Real World

GitLab CI is used to automate testing and deployment in software projects, saving time and reducing errors.

💼 Career

Understanding GitLab CI basics is essential for DevOps roles and developers working with continuous integration pipelines.

1

Create the basic GitLab CI file

Create a file named .gitlab-ci.yml and add the line stages: with a list containing test to define the stages.

Git

# Your code here

Need a hint?

Use YAML syntax to define stages: followed by a list with - test.

2

Add the test job

Add a job named test that runs in the test stage. Use the stage keyword with value test.

Git

stages:
  - test

# Your code here

Need a hint?

Define a job by writing its name followed by stage: test.

3

Add the script to run

Inside the test job, add a script section that runs the command echo "Running tests...".

Git

stages:
  - test

test:
  stage: test
  # Your code here

Need a hint?

Use script: followed by a list with the echo command.

4

Check the job output

Run the GitLab CI pipeline and verify that the output contains the text Running tests.... Write a command to simulate this by printing Running tests....

Git

stages:
  - test

test:
  stage: test
  script:
    - echo "Running tests..."

# Your code here

Need a hint?

Use echo "Running tests..." to show the output.
