## 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
|
|
pip install flask-mail
|
|
pip install pyjwt
|
|
Prod only, require sys packages:
|
|
pip install mariadb
|
|
pip install uwsgi
|
|
...
|
|
```
|
|
|
|
Freeze/requirements.txt. Better to audit this inside python:3-bookworm-slim container.
|
|
```
|
|
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
|
