WIP example
Goal:
Load balance port 6443 (the K8s/K3s API server) against a dynamic list of upstream servers using a file for endpoint discovery.
- Dynamic configuration
- Load balancing port 6443 between a list of endpoints
- TCP Proxy only (
type.googleapis.com/envoy.extensions.filters.network.tcp_proxy.v3.TcpProxy
) - not HTTP/TLS
Commands to test:
$ docker run -p 10000:10000 -p 6443:6443 \
-t -i -v `pwd`:/etc/envoy \
--entrypoint /bin/bash --rm \
envoyproxy/envoy-dev:4c0e53d8cee46d9d886ceed011b1a52000d261cf
# cd /etc/envoy
# envoy -l debug -c ./envoy.yaml
Other commands:
envoy -c ./envoy.yaml --service-cluster k3s_service --service-node k3s_service
