Example yaml file name must be **.gitlab-ci.yaml**

```yaml
stages:
  # - test
  - build
  - deploy

pre-job:
  stage: .pre
  script:
    - echo 'This message is from .pre-job'

build-job:
  stage: build
  script:
    - echo 'This message is from build-job'

test-job:
  stage: test
  script:
    - echo 'This message is from test-job'

deploy-job:
  stage: deploy
  script:
    - echo 'This message is from deploy-job'
    
post-job:
  stage: .post
  script:
    - echo 'This message is from .post-job'
```

Default stages use default order other than that you can use
```yaml
stages:
	-test1
	-test2
	-test3
```

Example:
```yaml
stages:
  - build
  - deploy

build:
  image: node
  stage: build
  script:
    # - apt update -y
    # - apt install npm -y
    - npm install
  artifacts:
    paths:
      - node_modules
      - package-lock.json
    # expire_in: 1 week 

deploy:
  image: node
  stage: deploy
  script:
    # - apt update -y
    # - apt install nodejs -y
    - node index.js > /dev/null 2>&1 & # these command runs in background and does not effect timeout
```


## Gitlab Runners

Application that works for picking CI/CD and execute CI/CD jobs.


Settings > shared runners or specific runners 

Runners has tag like docker mongodb ruby. That means which can runners can handle.

for example windows tag we can use in our yaml.
```yaml
windows-info:
    tags:
        - windows
    script:
        - systeminfo
```

Runner must be same version with gitlab.

**sudo gitlab-runner register** for register runner. You can take runner token from setttings

run gitlab-runner locally 
```yaml
stages:
    - build_stage
    - deploy_stage

build:
    stage: build_stage
    script:
        - docker --version
        - docker build -t pyapp .
    tags:
        - localshell
        - localrunner

deploy:
    stage: deploy_stage
    script:
        - docker stop pyappcontainer1 || true && docker rm pyappcontainer1 || true
        - docker run -d --name pyappcontainer1 -p 8080:8080 pyapp
    tags:
        - localshell
        - localrunner
```

 Git-runner add admin group ==> sudo usermod -aG docker gitlab-runner

![[Screenshot from 2023-03-14 13-08-06.png]]

Variables ==> use security token,url , long string etc.
Gitlab variable [url](https://docs.gitlab.com/ee/ci/variables/predefined_variables.html)

predefine 
```yaml
demo_job:
  script:
    - echo $CI_COMMIT_MESSAGE
    - echo $CI_JOB_NAME
```

direcly set in yaml
```yaml
variables:
    name: 'John'
    message: 'How are you?'

display_message:
    variables:
        name: 'Mark'
    script:
        - echo "Hello $name, $message"
```

secret variable

```yaml
push_image:
    script:
        - docker login -u $USERNAME -p $PASSWORD
        - docker tag pyapp:latest $USERNAME/mypyapp:latest
        - docker push $USERNAME/mypyapp:latest
    tags: 
        - localshell

```

```
1) Create Custom Quality Gate in SonarCloud and Add conditions to the Quality Gate
2) Assign this Quality Gate to the Project
3) Add script in .gitlab-ci.yml file to enable quality gate check (Note: This will fail your build in case Quality Gate fails)
