Gillotina
To run apps built with the Guillotina web framework using Unit:
-
Install Unit with a Python 3.7+ language module.
-
Create a virtual environment to install Guillotina’s PIP package, for instance:
$ cd /path/to/app/ # Path to the application directory; use a real path in your configuration $ python --version # Make sure your virtual environment version matches the module version Python X.Y.Z # Major version, minor version, and revision number $ python -m venv venv # Arbitrary name of the virtual environment $ source venv/bin/activate # Name of the virtual environment from the previous command $ pip install guillotina $ deactivate
Warning:
Create your virtual environment with a Python version that matches the language module from Step 1 up to the minor number (X.Y in this example). Also, the app type in Step 5 must resolve to a similarly matching version; Unit doesn’t infer it from the environment. -
Let’s try a version of the tutorial app, saving it as /path/to/app/asgi.py:
from guillotina import configure from guillotina import content from guillotina import schema from guillotina.factory import make_app from zope import interface class IMyType(interface.Interface): textline = schema.TextLine() @configure.contenttype( type_name="MyType", schema=IMyType, behaviors=["guillotina.behaviors.dublincore.IDublinCore"], ) class MyType(content.Resource): pass @configure.service( context=IMyType, method="GET", permission="guillotina.ViewContent", name="@textline", ) async def textline_service(context, request): return {"textline": context.textline} # Callable name that Unit looks for application = make_app( settings={ "applications": ["__main__"], "root_user": {"password": "root"}, "databases": { "db": {"storage": "DUMMY_FILE", "filename": "dummy_file.db"} }, } )
Note that all server calls and imports are removed.
-
Change ownership:
Run the following command (as root) so Unit can access the application directory (If the application uses several directories, run the command for each one):
# chown -R unit:unit /path/to/app/ # User and group that Unit's router runs as by default
The unit:unit user-group pair is available only with official packages , Docker images, and some third-party repos. Otherwise, account names may differ; run theps aux | grep unitd
command to be sure.For further details, including permissions, see the security checklist.
-
Next, prepare the Guillotina configuration for Unit (use real values for type, home, and path):
{ "listeners": { "*:80": { "pass": "applications/guillotina" } }, "applications": { "guillotina": { "type": "python 3.Y", "type_comment": "Must match language module version and virtual environment version", "path": "/path/to/app/", "path_comment": "Path to the ASGI module", "home": "/path/to/app/venv/", "home_comment": "Path to the virtual environment, if any", "module": "asgi", "module_comment": "ASGI module filename with extension omitted", "protocol": "asgi", "protocol_comment": "Protocol hint for Unit, required to run Guillotina apps" } } }
-
Upload the updated configuration.
Assuming the JSON above was added to
config.json
. Run the following command as root:# curl -X PUT --data-binary @config.json --unix-socket \ /path/to/control.unit.sock \ # Path to Unit's control socket in your installation http://localhost/config/ # Path to the config section in Unit's control API
After a successful update, your app should be available on the listener’s IP address and port:
$ curl -XPOST --user root:root http://localhost/db \ -d '{ "@type": "Container", "id": "container" }' {"@type":"Container","id":"container","title":"container"}
$ curl --user root:root http://localhost/db/container { "@id": "http://localhost/db/container", "@type": "Container", "@name": "container", "@uid": "84651300b2f14170b2b2e4a0f004b1a3", "@static_behaviors": [ ], "parent": { }, "is_folderish": true, "creation_date": "2020-10-16T14:07:35.002780+00:00", "modification_date": "2020-10-16T14:07:35.002780+00:00", "type_name": "Container", "title": "container", "uuid": "84651300b2f14170b2b2e4a0f004b1a3", "__behaviors__": [ ], "items": [ ], "length": 0 }
