Unable to start envoy in docker-compose - docker

Question

I have this envoy.yaml

This file is copied from this official example.
But when I try to go ahead with the docs
$ docker-compose pull node-server envoy commonjs-client
$ docker-compose up node-server envoy commonjs-client
I get this:
ERROR: No such service: node-server
if I run docker-compose pull envoy I get ERROR: No such service: envoy
What did I miss?

It seems like I got the wrong assumption in my comments. This repository contains Dockerfiles with a context to create said image when running the docker compose command.
In your example, the command:
docker-compose pull node-server envoy commonjs-client
should check if the images are available locally. If not, they should be able to build them.
Confusing to me is that you pointed to a docker-compose.yaml file stashed away somewhere deep in the examples folder. If you were to run that command I can see why you'd get the error. The relative path to the envoy Dockerfile is ./net/grpc/gateway/docker/envoy/Dockerfile, which is not accessible from the echo location.
It should however be accessible from your project root (i.e. the directory of this file https://github.com/grpc/grpc-web/blob/master/docker-compose.yml). Have you tried running it from there?
Fyi: What should happen after a pull is compose notifying you that the image cannot be found in your local repository and proceeding to create it based on the Dockerfile it found in the path relative to root (./net/grpc/gateway/docker/envoy/Dockerfile).
