+# Enoncer du TP (en binôme)
+
+Pour réaliser ce TP, il est **conseillé** d'utiliser l'IDE intégré à GitLab.
+
+## Ce TP utilise
+
+- [GIT](https://git-scm.com/downloads)
+- [JDK11](https://www.oracle.com/fr/java/technologies/javase-jdk11-downloads.html#license-lightbox) 
+- [Maven 3.6.x](http://apache.mirrors.nublue.co.uk/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.zip)
+
+## Astuces
+
+- Gitlab inject des variables disponibles dans la CI, vous trouverez la liste [ici](https://docs.gitlab.com/ee/ci/variables/predefined_variables.html)
+- Vous pouvez aussi injecter vos propres variables dans **Settings > CICD**
+
+## Préparation
+
+1. Une personne par groupe doit récupérer le projet dans son espace personnel Gitlab
+2. Cette personne doit ajouter son binôme en tant que developer
+
+## Partie 1 - Configuration du repository
+
+1. Configurez le repository pour que personne ne puisse push directement sur la branche master
+2. Configurez le repository pour qu'il y ait au moins 1 approver sur une merge request
+3. Pour tester, créez une issue dans gitlab et initier une merge request à partir de l'issue
+
+## Partie 2 - Initialisation d'un pipeline dans gitlab-ci
+
+1. Créez une nouvelle issue + merge request
+2. Ajouter un fichier `.gitlab-ci.yml` à votre projet
+3. Faite en sorte que votre fichier gitlab-ci.yml lance un job de compilation
+4. Quand la compilation passe, vous devez créer un autre job permettant de lancer les tests unitaires
+5. Quand les tests unitaires passent, ajoutez un job, permettant de créer le FatJar
+
+## Partie 3 - Code Quality
+
+1. Créez vous un compte sur [SonarCloud](https://sonarcloud.io/) et créez votre Organization
+2. Créez une nouvelle issue + merge request
+3. Modifiez votre pom.xml permettant l'utilisation de sonar
+4. Modifiez votre pipeline pour que gitlab-ci execute sonar
+
+## Partie 4 - Versionning (Création de Tag)
+
+1. Créez une nouvelle issue + merge request
+2. Faite en sorte de pouvoir créer un tag via l'interface de gitlab-ci déclanchant un job manuel qui exécute:  
+    a. mvn release:prepare  
+    b. mvn release:perform  
+4. L'exécutable créé doit-être uploadé sur votre projet GitLab *(cf: Packages & Registries > Package Registry)*
+5. Vérfiez la présence du tag *(cf: Repository > Tags)*
+
+## Partie 5 - Dockerized (Création d'une image docker)
+
+1. Créez une nouvelle issue + merge request
+2. Lors de la création d'un tag, faites en sorte d'upload une image Docker du FatJar *(cf: Packages & Registries > Container Registry)*
+ 
+*Aide: [Plugin Maven Jib](https://github.com/GoogleContainerTools/jib/tree/master/jib-maven-plugin)*
+
+## Partie 6 - Déploiement
+
+1. Créez une nouvelle issue + merge request
+2. Faite en sorte que votre application se déploie automatiquement sur Heroku, une fois le tag créé
