Image for running python based git projects.
Should have and structure like the following:
${PROJECT_DIR} +
|
+-> README.md
+-> ...
+-> ${SRC_DIR} + (will be added to the PYTHONPATH)
|
+ app.py (main entry point, we call this in the end)
Should expose an endpoint that will be the one that we expose in docker.
Check https://github.com/periket2000/rest_api_demo.git, is a Flask app that exposes the api in 8888 port.
You can configure the app through the "env" property in the json file, in this case:
PROJECT_DIR: where everything will be installed inside the container.
GIT_REPO: the repo to download.
SRC_DIR: the source folder inside the project.
APP_FILE: entry point to python application.
