# Envoy proxy as an API gateway. Built with Bazel. Deployed into Kubernetes.

[Blog post](https://ekhabarov.com/envoy) with detailed explanation.

## Links

* [Envoy proxy](https://www.envoyproxy.io/)

* [Bazel](https://bazel.build/)

* [Bazelisk](https://github.com/bazelbuild/bazelisk#installation)

* [Kubernetes](https://kubernetes.io/)

* [Tilt](https://tilt.dev/)

* [Minikube](https://minikube.sigs.k8s.io/docs/start/)

## Usage

1. Install and start [minikube](https://minikube.sigs.k8s.io/docs/start/).

1. Install [Bazelisk](https://github.com/bazelbuild/bazelisk#installation).

1. Run Tilt.

```shell

% bazel run //tools:tilt-up

% grpcurl -plaintext \

  -d '{"name": "Bazel"}' \

  127.0.0.1:55000 svc.ServiceOne.Hello

{

  "body": "Hello, Bazel"

}

% curl -i \

  -H 'token: abc' \

  http://localhost:8080/v1/hello\?name\=Bazel

HTTP/1.1 200 OK

content-type: application/json

x-envoy-upstream-service-time: 2

grpc-status: 0

grpc-message:

content-length: 28

date: Tue, 21 Sep 2021 23:33:27 GMT

server: envoy

{

 "body": "Hello, Bazel"

}

% bazel run //tools:tilt-down

```

NOTE: Until `service-one` become available, Envoy will return HTTP 503:

`upstream connect error` or `no healthy upstream`
