![Conceptual Schema](https://raw.githubusercontent.com/gtesei/Patterns_for_Continuous_Integration_Docker_Travis_CI_2_DEV/master/img/end-to-end-flow.png)

__The “Docker repo” pattern__: _create two separate Git repositories: one for Docker release and another for software development. This keeps the Docker-specific code isolated from the actual software. Developers can continue working on the source software as usual, while the production Docker image is developed separately_

This repository is an example of the __Git repository for software development__. 

Specifically, we assume that the team uses some different branches and a certain point a pull-request for merge the master branch is necessary. After committing the master branch:
- before the commit, it is necessary to modify the version number in _setup.py_ so that a new release will be created on the package repository ([PyPI](https://pypi.org/) in our case) 
- on Travis CI a new job is created and __pytest__ tests are performed
- if tests are successful 
    - a new release will be created on the package repository ([PyPI](https://pypi.org/) in our case)
    - a two new docker development images will be released on the Docker Registry ([Docker Hub](https://hub.docker.com) in our case)
