# Flask
|
|
|
|
This bundle can deploy one or more Flask applications per node.
|
|
|
|
```python
|
|
'flask': {
|
|
'myapp': {
|
|
'app_module': "myapp",
|
|
'apt_dependencies': [
|
|
"libffi-dev",
|
|
"libssl-dev",
|
|
],
|
|
'env': {
|
|
'APP_SECRETS': "/opt/client_secrets.json",
|
|
},
|
|
'json_config': {
|
|
'this json': 'is_visible',
|
|
'inside': 'your template.cfg',
|
|
},
|
|
'git_url': "ssh://git@bitbucket.apps.seibert-media.net:7999/smedia/myapp.git",
|
|
'git_branch': "master",
|
|
'deployment_triggers': ["action:do-a-thing"],
|
|
},
|
|
},
|
|
```
|
|
|
|
The git repo containing the application has to obey some conventions:
|
|
|
|
* requirements-frozen.txt (preferred) or requirements.txt
|
|
* minimal setup.py to allow for installation with pip
|
|
|
|
The `app` instance has to exists in the module defined by `app_module`.
|
|
|
|
It is also very advisable to enable logging in your app (otherwise HTTP 500s won't be logged):
|
|
|
|
```python
|
|
import logging
|
|
|
|
if not app.debug:
|
|
stream_handler = logging.StreamHandler()
|
|
stream_handler.setLevel(logging.INFO)
|
|
app.logger.addHandler(stream_handler)
|
|
```
|
|
|
|
If you specify `json_config`, then `/opt/${app}/config.json` will be
|
|
created. The environment variable `$APP_CONFIG` will point to the exact
|
|
name. You can use it in your app to load your config:
|
|
|
|
```python
|
|
app.config.from_json(environ['APP_CONFIG'])
|
|
```
|
|
|
|
If `json_config` is *not* specified, you *can* put a static file in
|
|
`data/flask/files/cfg/$app_name`.
