# Sonarqube Configuration

## Setup Sonarqube

before first run, change permissions on sonarqube volumes dirs from root to 1000:
```bash
sudo chown 1000:1000 -R ./volumes/sonarqube
```

before start sonarqube vm.max_map_count must be changed on your host:
```bash
sudo sysctl -w vm.max_map_count=262144
```

after running, you can login with default credentials (admin:admin)

## Configure projects

first step is create access token in gitlab and set it in sonarqube app

next one is choice of repository, if you did choice, you will saw instruction.

we must create ```sonar-project.properties``` file in choosen repo:

```properties
sonar.projectKey=<repo_name_and_hash>
sonar.qualitygate.wait=true
```

we must define also ```.gitlab-ci.yml``` file in choosen repo:

```yml
sonarqube-check:
  image: 
    name: sonarsource/sonar-scanner-cli:latest
    entrypoint: [""]
  variables:
    SONAR_USER_HOME: "${CI_PROJECT_DIR}/.sonar"  # Defines the location of the analysis task cache
    GIT_DEPTH: "0"  # Tells git to fetch all the branches of the project, required by the analysis task
  cache:
    key: "${CI_JOB_NAME}"
    paths:
      - .sonar/cache
  script: 
    - |
      sonar-scanner \
        -Dsonar.projectKey="${SONAR_REPO_ID}" \
        -Dsonar.sources=. \
        -Dsonar.host.url="${SONAR_HOST_URL}" \
        -Dsonar.login="${SONAR_TOKEN}"
  allow_failure: true
  only:
    - develop
```

last step is define envs in gitlab -> choosen repo -> Settings -> CI/CD -> Variables:

```env
SONAR_REPO_ID=<repo_name_and_hash>
SONAR_HOST_URL=http://<sonarqube_url_or_dns>:<sonarqube_shared_port>
SONAR_TOKEN=<sonar_token>
```

you can generate ```SONAR_TOKEN``` in Overview -> Locally

you can get ```SONAR_REPO_ID``` from Overview -> Gitlab-CI in ```sonar-project.properties``` file creating statement
