Python Flask settings

In case of Python Flask, the file is compose/docker-compose.override.yml-python-flask. This file must be copied into the root of the Devilbox git directory.

What	How and where
Example compose file	`compose/docker-compose.override.yml-all` or `compose/docker-compose.override.yml-python-flask`
Container IP address	`172.16.238.250`
Container host name	`flask1`
Container name	`flask1`
Mount points	`data/www``
Exposed port	none
Available at	Devilbox intranet via Reverse Proxy configuration
Further configuration	`example_setup_reverse_proxy_python_flask`

Python Flask env variables

Additionally the following .env variables can be created for easy configuration:

Variable	Default value	Description
`FLASK_PROJECT`	none	Specifies your Python Flask project dir in data/www.
`PYTHON_VERSION`	`3.8`	Specifies the Python version to use for Flask.

Instructions

1. Copy docker-compose.override.yml

Copy the Python Flask Docker Compose overwrite file into the root of the Devilbox git directory. (It must be at the same level as the default docker-compose.yml file).

host> cp compose/docker-compose.override.yml-python-flask docker-compose.override.yml

* docker_compose_override_yml * add_your_own_docker_image * overwrite_existing_docker_image

2. Adjust `.env` settings (optional)

Python Flask is using sane defaults, which can be changed by adding variables to the .env file and assigning custom values.

Add the following variables to .env and adjust them to your needs:

# Project directory in data/www
FLASK_PROJECT=my-flask

# Python version to choose
#PYTHON_VERSION=2.7
#PYTHON_VERSION=3.5
#PYTHON_VERSION=3.6
#PYTHON_VERSION=3.7
PYTHON_VERSION=3.8

3. Configure Reverse Proxy

Before starting up the devilbox you will need to configure your python flask project and the reverse proxy settings.

TL;DR

For the lazy readers, here are all commands required to get you started. Simply copy and paste the following block into your terminal from the root of your Devilbox git directory:

# Copy compose-override.yml into place
cp compose/docker-compose.override.yml-flask1 docker-compose.override.yml

# Create .env variable
echo "# Project directory in data/www"   > .env
echo "FLASK_PROJECT=my-flask"           >> .env
echo "# Python version to choose"       >> .env
echo "#PYTHON_VERSION=2.7"              >> .env
echo "#PYTHON_VERSION=3.5"              >> .env
echo "#PYTHON_VERSION=3.6"              >> .env
echo "#PYTHON_VERSION=3.7"              >> .env
echo "PYTHON_VERSION=3.8"               >> .env

before starting up the devilbox you will need to configure your python flask project and the reverse proxy settings.
