slide deck
During this demo we are going to deploy a front Envoy and a couple of services coloated with a running service Envoy.
The three containers will be deployed inside a virtual network called enovymesh using docker-compose.
Port 8080, 8443, and 8001 are exposed by docker-compose and can handle HTTP, HTTPS calls to services and requests to /admin.
In this demo, all requests are handled by the service Envoy, and efficiently routed to your services.
docker-compose build --pull
docker-compose up -d
docker-compose ps
Route 1, Service1:
curl -v http://localhost:8080/service/1
Route 2, Service2:
curl -v http://localhost:8080/service/2
Using HTTPS to call services behind the front Envoy:
curl -k -v https://localhost:8443/service/1
Scale up service1 nodes to demonstrate load balancing capabilities of Envoy:
docker-compose scale service1=3
Send 3 requests and watch as Envoy load balanes doing a round robin of the three services:
for x in $(seq 5); do curl -v localhost:8080/service/1; done
When Envoy runs, it also attaches an admin to your desired port. We have admin bound to port 8001.
/server_info- info about the Envoy version running/stats- stats about the envoy server, number of requests fulfilled by them, info about http ingress
docker-compose exec front-envoy /bin/bash
curl localhost:8001/server_info
curl localhost:8001/stats
