boiler_flask

A Python boilerplate for services using Flask, wrapped in venv inside a Docker container.

Runtime architecture

Application Service Container
    Venv ( python virtual environment )
        Flask ( micro-framework )
        
Database Docker Container
    ENV ( data reference to parent file system ) 
    DBMS & tooling processes

Development

Host Requirements

• python 3.6^
• virtualenv
• node
• npm install -g gulp
• Docker CE
• npm install -g newman

Integration Server

• same as host

Installation

• npm install
• gulp install

Changing ENV settings

• gulp env

IDE Setup

Make sure that your python interpreter is reading from the .virtual directory

Running

Running the application and database container. Modifying files will not refresh the container as the volumes for these containers are on the host system docker-compose up

Unit Testing

• gulp unit
• gulp unit-w

Deployment

This is a bit of a different path than running docker-compose as this uses the Dockerfile to take advantage of the COPY command so that these images can contain all of the source necessary to self execute w/ out volumes.

Strategy

Get an instance of mongo from DockerHub docker pull mongo

Create a MongoDB container called mongodb docker run --name mongodb -d -v $(pwd)/data/db:/data/db mongo

Build or checkout your image docker build -t <img-tag> . -f <Dockerfile>

Run a container, linking it to mongodb docker run --name <container-name> -d -p <ports> --link mongodb <img-tag>

Versifying

We use SemVer for versifying.
