Making our CI/CD Pipeline

Config File

To create our pipeline, we must first create a .gitlab-ci.yml file and specify it to our project requirements (Place this in your project root)

Templates

Syntax Reference

image: golang:1.22  

stages:
  - test
  - build

build:
  stage: build
  script:
    - "go build -o calculator"
    - "./calculator"

test:
  stage: test
  script:
    - "go test"

Paste the code then push it to your repository

> git add .\.gitlab-ci.yml 
> git commit -m "Created GO Pipeline"
> git push

We can now view our pipeline from the repository, under Build -> Pipeline -> Pipeline Number

Viewing our deployed pipeline

Testing for Failures

Just like in Simple Calculator Project, we can test for failures by changing the values slightly

First, we'll create a separate branch to mimic a real project, then change the test values from there

Push your changes then wait for the pipeline to finish running

We can now fix it back and create a merge request to main. Merge requests will trigger a pipeline job to check for errors before letting you merge (depending on your project settings)
