Enable routing between multiple OpenFaaS gateways or providers
faas-federation
faas-federation is an implementation of the faas-provider which can be used to unify one or more OpenFaaS clusters under a single API.
Why do we need this?
This project exists to join together two or more distinct OpenFaaS clusters.
- Multi-region - east/west
Get a single API / control-plane for one or more clusters split by location, such as east/west.
- Edge locations
You may have one or more edge locations (or even ARM/IoT OpenFaaS installations). You can join them together under a single set of credentials and control plane.
- Varying provider types
You can connect two or more different OpenFaaS provider types together. For instance: Kubernetes (faas-netes) and Lambda (faas-lambda). This means you can have a single, centralized control-plane but deploy to both AWS Lambda and Kubernetes at the same time.
Getting started
faas-federation can replace your provider in your existing OpenFaaS deployment.
More coming soon.
Example
Coming soon: deploy OpenFaaS with two separate faas-memory providers.
helm chart
See also: example of Kubernetes and AWS Lambda federated configuration in the sample helm chart.
Gateway routing
To route to one gateway or another, simply set com.openfaas.federation.gateway to the name you want to pick.
| Annotation | Description |
|---|---|
com.openfaas.federation.gateway |
route the request based on the provider name i.e. faas-netes, faas-lambda |
Configuration
All configuration is managed using environment variables
| Option | Usage | Default | Required |
|---|---|---|---|
providers |
comma separated list of provider URLs i.e. http://faas-netes:8080,http://faas-lambda:8080 |
- | yes |
default_provider |
default provider URLs used when no deployment constraints are matched i.e. http://faas-netes:8080 |
- | yes |
