OpenFaaS Nats Connector

The Nats connector invokes functions based on Nats topic annotations.

Prerequisites

Install OpenFaaS

You must have a working OpenFaaS installation. You can find instructions in the docs, including instructions to also install OpenFaaS via Helm.

Install the Chart

Add the OpenFaaS chart repo and deploy the nats-connector chart. We recommend installing it in the same namespace as the rest of OpenFaaS

$ helm repo add openfaas https://openfaas.github.io/faas-netes/
$ helm upgrade nats-connector openfaas/nats-connector \
    --install \
    --namespace openfaas

The above command will also update your helm repo to pull in any new releases.
