## Workflow:
- should work with flask run locally and dockerfile build
- local dev
- local / venv pip install
- record versionless pips manually here
- pip freeze snapshots into project requirements
- docker build then copies frozen requirements


## pip:
mariadb may take extra work: gcc, libmariadb-dev 
```
pip install flask
pip install python-dotenv
pip install flask-wtf
pip install flask-sqlalchemy
pip install flask-migrate
pip install flask-login
pip install email-validator
pip install pydenticon
Prod only, require sys packages:
pip install mariadb
pip install uwsgi
...
pip freeze > requirements.txt
```

## db cheat:
After db schema change:
```
flask db migrate -m "add users table"
flask db upgrade
```

Dump data if db in good state:
```
flask db downgrade base
flask db upgrade
```

Full reset or maria init:
```
sql:
drop table users;
drop table posts;
rm app.db
rm -r migrations
flask db init
flask db migrate
flask db upgrade
```

## build notes:

Dockerfile needs dockerignore or preferably explicitly defined copies for:
- app
- config
- project dir
- requirements
- not dotflaskenv, vars set with dockerfile

## docker setup:
- py logger handler StreamHandler is buggy to the point of being useless. Use logfile and link to stdout in Docker build

## notes:
- compose has entry that overrides flask with uwsgi for prod
- miminal environment vars come through project env, pass through compose
- no dotenv here, dotflaskenv goes into image
- keep env untracked but templated, dotflaskenv is tracked and public
