pop-gate 1

INSTALLATION

pip install pop-gate

USAGE

Run the gate server from the command line and expose specific patterns of hub references. The ‘–refs’ represent patters on the hub that are allowlisted. The ‘–prefix’ tells gate to assume that all refs are under a specific dynamic namespace.

In this example we will use a prefix of “gate” and allow all refs under ‘hub.gate.init’

gate --prefix gate --refs "init.*"

Use curl to run hub.gate.init.test() on the remote server like so:

curl http://localhost:8080 -H "Content-Type: application/json" -d '{"ref": "init.test"}'

Keyword arguments can be passed by adding extra keys to the call:

curl http://localhost:8080 -H "Content-Type: application/json" -d '{"ref": "init.test", "kwarg1": "value1", "kwarg2": "value2"}'

TESTING

Install gate locally with testing libraries:

git clone git@gitlab.com:saltstack/pop/gate.git
pip install -e gate -r requirements-test.txt

Run the tests with pytest

pytest tests

INTEGRATION

In order to use gate in your own project add the gate config to your conf.py like so:

my_project/conf.py

CLI_CONFIG = {
    # Gate options
    "host": {"source": "gate"},
    "port": {"source": "gate"},
    "server": {"source": "gate"},
    "matcher": {"source": "gate"},
    "prefix": {"source": "gate"},
    "refs": {"source": "gate", "default": ["gate.init.test"]},
}

Add gate startup code to your project’s initializer like so:

my_project/my_project/init.py

def __init__(hub):
    # Horizontally merge the gate dynamic namespace into your project
    hub.pop.sub.add(dyne_name="gate")

def cli(hub):
    # Load the config from gate onto hub.OPT
    hub.pop.config.load(["my_project", "gate"], cli="my_project")

    # Create the asyncio loop
    hub.pop.loop.create()

    # Get the default gate server, and other options from hub.OPT.gate
    gate_server = hub.OPT.gate.server

    # Create the server coroutine
    coro = hub.gate.init.start(gate_server=gate_server)

    # Start the gate server
    hub.pop.Loop.run_until_complete(coro)
