proxy-informer

proxy-informer helps run a highly available Celo Proxy on Kubernetes by dynamically discovering Proxies and re-configuring a specified Validator.

Usage

Add a proxy-informer container to run as a sidecar to each Pod running a Celo validator container. The proxy-informer sidecar discovers proxies running on the Kubernetes cluster and makes JSONRPC requests to update the validator's proxy configuration.

e2e has an example usage.

Proxy discovery

Command-line arguments configure the proxy-informer:

Argument	Default	Description
-proxy-namespace	default	Namespace to search for proxy Pod objects
-proxy-label-selector	proxy=true	Label selector to identify Pod objects

The proxy-informer discovers internal and external enode URL values by reading two annotations on Pod objects:

Annotation	Description
proxy.mantalabs.com/internal-enode-url	Internal enode URL
proxy.mantalabs.com/external-enode-url	External enode URL
