-🔁 Mise à jour de la branche product depuis develop : workflow recommandé
-⚙️ Étapes standards :
-Travaille uniquement sur develop
-
-Quand tu es prêt à mettre en production :
-
-
-
-git checkout product
-git merge develop
-git push origin product
-Cela fusionne proprement toutes les modifications testées de develop vers product.
-
-🖥️ Et sur le VPS ?
-Si ton VPS suit la branche product, alors une fois que tu as fait :
-
-git push origin product (sur pycharm)
-Tu peux te connecter à ton VPS et faire :
-
-cd /home/debian/Gestion_sondes git pull origin product
-
-🔵 Mettre à jour supervisor
-cd /etc/supervisor/conf.d
-supervisorctl restart all
-Et pour vérifier le bon état des services
-supervisorctl status
-exit
-exit
-
-🔵 4. Vérification
-
-pour vérifier que les scripts tournent bien.
