In a fierce competitive context between the different tea shops in the sale of tea, the company thétiptop gave us a project to create an online game website with tickets in order to win lots of teas. With my team of experts, we created a website named Thétiptop whose site you can view on https://thetiptop-jeux-concours.dsp-archiweb21-ah-es-ag-hk.fr/ to see the site that we created to adapt to the current context and the expectations of today's customers. Our server is managed by Traefik (https://traefik.dsp-archiweb21-ah-es-ag-hk.fr/dashboard/#/) which centralizes secure access to all our services which are gogs (similar host to github which hosts our application, https://gogs.dsp-archiweb21-ah-es-ag-hk.fr/gogs/thetiptop), and Jenkins (Platform where we can run jobs automatically and continuously updating the application regularly thanks to an ssh connection to the gogs repository of our project, of which when we carry out a commit, that is to say an update save on this gogs repository of our application and which makes it possible to verify that the process of continuous integration validates the functional part of the application during a new update). These three services in addition to the website itself are docker images described in a yaml docker-compose file which allows to manage independently in a more efficient way these different docker images which make creating executable and modifiable containers easily. Technologies: Angular 9, Bootstrap 4, HTML5 / CSS3, Node JS, Sequelize, Docker, Docker-compose, Dockerfile, Shell, Jenkins, Gogs, Traefik
