rq-scheduler-dashboard

Introduction

rq-scheduler-dashboard is a copy of rq-dashboard for rq-scheduler jobs, based on the code from this PR: https://github.com/ducu/rq-dashboard/pull/95. This just wraps the code from @helenst into a separate package.

It looks like this

Installing

.. code:: console

$ pip install rq-scheduler-dashboard

Running the dashboard

Run the dashboard standalone, like this:

.. code:: console

$ rq-scheduler-dashboard
* Running on http://127.0.0.1:9181/
...

.. code:: console

$ rq-scheduler-dashboard --help
Usage: rq-scheduler-dashboard [OPTIONS]

  Run the RQ Scheduler Dashboard Flask server.

  All configuration can be set on the command line or through environment
  variables of the form RQ_SCHEDULER_DASHBOARD_*. For example RQ_SCHEDULER_DASHBOARD_USERNAME.

  A subset of the configuration (the configuration parameters used by the
  underlying flask blueprint) can also be provided in a Python module
  referenced using --config, or with a .cfg file referenced by the
  RQ_SCHEDULER_DASHBOARD_SETTINGS environment variable.

Options:
  -b, --bind TEXT               IP or hostname on which to bind HTTP server
  -p, --port INTEGER            Port on which to bind HTTP server
  --url-prefix TEXT             URL prefix e.g. for use behind a reverse proxy
  --username TEXT               HTTP Basic Auth username (not used if not set)
  --password TEXT               HTTP Basic Auth password
  -c, --config TEXT             Configuration file (Python module on search
                                path)
  -H, --redis-host TEXT         IP address or hostname of Redis server
  -P, --redis-port INTEGER      Port of Redis server
  --redis-password TEXT         Password for Redis server
  -D, --redis-database INTEGER  Database of Redis server
  -u, --redis-url TEXT          Redis URL connection (overrides other
                                individual settings)
  --interval INTEGER            Refresh interval in ms
  --help                        Show this message and exit.

Integrating the dashboard in your Flask app

The dashboard can be integrated in to your own Flask_ app by accessing the blueprint directly in the normal way, e.g.:

.. code:: python

from flask import Flask
import RQ_SCHEDULER_DASHBOARD

app = Flask(__name__)
app.config.from_object(RQ_SCHEDULER_DASHBOARD.default_settings)
app.register_blueprint(RQ_SCHEDULER_DASHBOARD.blueprint)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

The cli.py:main entry point provides a simple working example.

Developing

We use piptools_ to keep our development dependencies up to date

::

$ pip install --upgrade pip
$ pip install git+https://github.com/nvie/pip-tools.git@future

Now make changes to the requirements.in file, and resolve all the 2nd-level dependencies into requirements.txt like so:

::

$ pip-compile --annotate requirements.in

Develop in a virtualenv and make sure you have all the necessary build time (and run time) dependencies with

::

$ pip install -r requirements.txt

Develop in the normal way with

::

$ python setup.py develop

Then use Fabric to perform various development tasks. For example, to tag, build and upload to testpypi

::

$ git tag 0.3.5   # no 'v' prefix or anything
$ fab build
$ fab upload

This requires write access to both the GitHub repo and to the PyPI test site.

See fab -l for more options and fab -d <subcommand> for details.

Maturity notes

The RQ Scheduler Dashboard is currently being developed and is in beta stage.
