Creating “Hello World” CI/CD Pipeline on Gitlab for testers.

1. Register free account at https://gitlab.com/users/sign_up OR sign into your existing account.
2. Create new project (new repo) in the https://gitlab.com homepage.
3. If your account is not set up locally, you might have to run following commands.

$ git config –-global user.email “[email address]”
$ git config –-global user.name “[your name]”

Also create a Personal Access Token at Gitlab and use it as password for your user account when promoted for password.

4. Copy the project URL and clone it locally.
$ git clone <your_project_URL> in your terminal (CLI)

Clone the project locally via HTTPS URL.

5. Now, you can add the the CI/CD Pipeline yam file named ‘.gitlab-ci.yml’ as shown below in the top folder level.

stages:          # List of stages for jobs, and their order of execution
  - build
  - test
  - deploy

build-job:       # This job runs in the build stage, which runs first.
  stage: build
  script:
    - echo "Compiling the code..."
    - echo "Compile complete."

unit-test-job:   # This job runs in the test stage.
  stage: test    # It only starts when the job in the build stage completes successfully.
  script:
    - echo "Running unit tests... This will take about 60 seconds."
    - sleep 60
    - echo "Code coverage is 90%"

lint-test-job:   # This job also runs in the test stage.
  stage: test    # It can run at the same time as unit-test-job (in parallel).
  script:
    - echo "Linting code... This will take about 10 seconds."
    - sleep 10
    - echo "No lint issues found."

deploy-job:      # This job runs in the deploy stage.
  stage: deploy  # It only runs when *both* jobs in the test stage complete successfully.
  script:
    - echo "Deploying application..."
    - echo "Application successfully deployed."

6. Check-in the file from the git CLI terminal by giving following commands.

$ git status
$git add .
$git commit -m “adding gitlab CI/CD for the first time”
$git push

7. Now you can see the the CI/CD pipeline working under the project as shown below.

Congrats you made your first hello world Gitlab Pipeline.
