API Gateway for Python to link to docker containers based on a backend config.

• python 3.8
• pip

From the repository root:

virtualenv ./env
source ./env/bin/activate
pip install -U -r requirements.txt

Activate your virtualenv, then use python from the env to launch the application as described below.

This repo comes pre-configured with two backends, orchestrated by docker-compose.

You'll need to start off with docker-compose build, then follow with docker-compose up. This sets up necessary labels and port mapping.

See python rgate.py --help, or:

python rgate.py --port 8080 --config ./cfg.yaml

Note: RGate will fail at startup if there are no containers to serve a backend. The error should be clear. If a container fails after start-up, requests to that backend will receive a 503.
