This project used :

  • Tomcat

  • Spring

    • MVC
    • Transaction
    • Security (with login)
    • WebServices with REST
    • Localization i18n

  • Hibernate Validation

  • JPA and Hibernate (with Criteria)

  • Docker & docker Compose

    • Dockerfile, dind, ...

  • Maven & organization with modules

    • Maven configuration with rapports
    • CheckStyle

  • Concepts of DAO, DTO, Services, Mappers, Paginator

  • Logs (LogBack)

  • JSPs, JSTL, and Tags

  • jQuery lib (jquery, jQuery UI, jQuery Validation)

  • Units Testing & Integration testing with Selenium

  • Continuous delivery (Jenkins)

  • Old concepts (in previous commits)

    • Servlets
    • JDBC
    • ThreadLocal
    • Singleton enum Pattern
    • Connection Pool (today managed by Spring Datasource)
    • Spring Security (authentication with Digest)

Utilisation

First at all, be into the root folder of the project

To launch the test server :

docker-compose -f dockers/docker-compose-envtest.yml up test_server

To launch Unit tests :

docker-compose -f dockers/docker-compose-envtest.yml up unit_test

To launch Integration testing :

docker-compose -f dockers/docker-compose-envtest.yml up selenium_test

To launch Production Server : (if the docker is not build, you need to generate the war of the front-webapp project)

docker-compose -f dockers/docker-compose-envtest.yml up tomcat_webapp

To launch stress tests : TODO

Points to view

4.4.3 Glazer Container Agent

The Glazer Container Agent is a simple webapp that allow us to manage Docker containers.

Create a Docker container with a Glazer Container Agent. This container will be your staging server. Like the Jenkins container, this container must be able to start containers (Docker in Docker).

Create two Docker images: one for the computer database webapp and one for the mysql. Once again use docker-compose to describe your services. Push them to DockerHub.

Add another job in your Jenkins that updates the computer-database-webapp image with the latest successful war and pushes it to DockerHub. Then ask your Glazer Container Agent container to create a new container from the latest image. This job must be triggered only if the UT tests pass.

4.5.2. Point overview: Continuous Integration (t0 + 18 days)

Jenkins + DinD: Which service actually starts the containers ? How to share directories between containers ?
Glazer Container Agent + DinD: How to handle container port mapping ? (2 solutions)
DockerHub: Automated builds limitations ?
