How to configure Traefik to be in front of Nginx and a PHP-FPM WebSocket server? - websocket

I'd like to use Traefik as a reverse proxy behind a Ratchet WebSocket server (3rd option suggested in deploy section).
The goal is to manage HTTPS and wss with the reverse proxy while keeping a simple HTTP and ws on the Ratchet server.
My WebSocket server exposes on port 8080, like in this example:
public function run()
{
$loop = React\EventLoop\Factory::create();
$pusher = new Pusher();
// Listen for the web server to make a ZeroMQ push after an AJAX request
$context = new React\ZMQ\Context($loop);
$pull = $context->getSocket(ZMQ::SOCKET_PULL);
$pull->bind('tcp://0.0.0.0:5555');
$pull->on('message', array($pusher, 'onEntry'));
// Set up our WebSocket server for clients wanting real-time updates
$webSock = new React\Socket\Server('0.0.0.0:8443', $loop);
$webServer = new IoServer(
new HttpServer(
new WsServer(
new WampServer(
$pusher
)
)
),
$webSock
);
$loop->run();
}
Following this post, I have been able to configure HTTPS via Traefik.
Here is my simplified docker-compose.yml:
nginx:
image: wodby/nginx:$NGINX_TAG
container_name: "${PROJECT_NAME}_nginx"
depends_on:
- php
environment:
NGINX_STATIC_OPEN_FILE_CACHE: "off"
NGINX_ERROR_LOG_LEVEL: debug
NGINX_BACKEND_HOST: php
NGINX_SERVER_ROOT: /var/www/html/webroot
NGINX_VHOST_PRESET: $NGINX_VHOST_PRESET
volumes:
- ./html:/var/www/html:cached
labels:
- "traefik.http.routers.${PROJECT_NAME}_nginx.rule=Host(`${PROJECT_BASE_URL}`)"
- "traefik.http.middlewares.${PROJECT_NAME}_nginx_https.redirectscheme.scheme=https"
- "traefik.http.routers.${PROJECT_NAME}_nginx.entrypoints=web"
- "traefik.http.routers.${PROJECT_NAME}_nginx.middlewares=${PROJECT_NAME}_nginx_https#docker"
- "traefik.http.routers.${PROJECT_NAME}_nginx_https.rule=Host(`${PROJECT_BASE_URL}`)"
- "traefik.http.routers.${PROJECT_NAME}_nginx_https.tls=true"
- "traefik.http.routers.${PROJECT_NAME}_nginx_https.entrypoints=websecure"
php:
build:
context: .
dockerfile: docker/php-fpm/Dockerfile
container_name: "${PROJECT_NAME}_php"
volumes:
- ./html:/var/www/html
labels:
- "traefik.http.routers.php.rule=Host(`${PROJECT_BASE_URL}`)"
traefik:
image: traefik:v2.0
container_name: "${PROJECT_NAME}_traefik"
command:
- "--api.insecure=true"
- "--entrypoints.web.address=:80"
- "--entrypoints.websecure.address=:443"
- "--providers.docker=true"
- "--providers.file.filename=/etc/traefik/dynamic_conf/config.yml"
- "--providers.file.watch=true"
ports:
- "80:80"
- "443:443"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
- "./docker/traefik/config.yml:/etc/traefik/dynamic_conf/config.yml" # used to define the certificate path
- "./docker/certs:/tools/certs"
However, how can I now forward HTTPS/wss to HTTP/ws to the php service?

OpenTelemetry exporter endpoint is not working in docker

I have .NET Core Web API Server and OpenTelemetry collector as docker container. But with my docker-compose, any event from web server does not be sent to otel collector container while it is working using "http://localhost:4318" as otlp endpoint without docker.
My docker-compose.yml:
version: "2.1"
services:
web:
build:
context: ..
dockerfile: ./MyWebServer/Dockerfile
container_name: web
networks:
- test_net
ports:
- "8080:80"
otel:
image: "otel/opentelemetry-collector:latest"
container_name: otel
command: ["--config=/etc/otel-collector-config.yml"]
volumes:
- ./OpenTelemetry/otel-collector-config.yml:/etc/otel-collector-config.yml
networks:
test_net:
ipv4_address: 172.23.10.4
ports:
- "4318:4318"
networks:
test_net:
ipam:
config:
- subnet: 172.23.0.0/16
My Program.cs:
using System.Diagnostics;
using OpenTelemetry.Resources;
using OpenTelemetry.Trace;
const string serviceName = "MyWebServer";
const string serviceVersion = "1.0.0";
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllers();
builder.Services.AddOpenTelemetryTracing(tracerProviderBuilder =>
{
tracerProviderBuilder
.AddOtlpExporter(opt =>
{
opt.Endpoint = new Uri("http://172.23.10.4:4318");
opt.Protocol = OtlpExportProtocol.HttpProtobuf;
})
.AddSource(serviceName)
.SetResourceBuilder(
ResourceBuilder.CreateDefault()
.AddService(serviceName: serviceName, serviceVersion: serviceVersion))
.AddHttpClientInstrumentation()
.AddAspNetCoreInstrumentation()
.AddSqlClientInstrumentation();
});
var app = builder.Build();
app.UseRouting();
app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
app.Run();
You dont need to use IPaddress here. you can use service name and docker will resolve it automatically for you.
opt.Endpoint = new Uri("http://172.23.10.4:4318");
so in your case it should be
opt.Endpoint = new Uri("http://otel:4318");

Laravel Dusk is not working on Docker/ docker-compose.yaml

I am working on a Laravel project. I started writing browser tests using Dusk. I am using docker as my development environment. When I run the tests, I am getting the "Connection refused" error.

I run the tests running the following command.
docker-compose exec php-fpm php artisan dusk
Then I get the following error.

What I do after is

I then try to run behat

My test simply tries to visit and print the homepage.
FeatureContext.php
use Behat\Behat\Context\Context;

use Behat\Gherkin\Node\TableNode;

class FeatureContext extends Behat\MinkExtension\Context\MinkContext implements Context, SnippetAcceptingContext
{
/**

* Every scenario gets its own context instance.
* You can also pass arbitrary arguments to the
* context constructor through behat.yml.
*/
public function __construct()
{
}
/**
* #Given that I am on the homepage
*/
public function thatIAmOnTheHomepage()
{
$this->iAmOnHomepage();
$this->visit("https://localhost:80");
$this->printLastresponse();
}
/**
* #Given that name is :arg1
*/
public function thatNameIs($arg1)
{
$this->fillField('name', $arg1);
}
/**

public function thatEmailIs($arg1)
{
$this->fillField('email', $arg1);
}
/**
* #When you try to register

public function youTryToRegister()
{
$this->pressButton('registerButton');
}
/**
* #Then you remain on the homepage
*/
public function youRemainOnTheHomepage()
{
assertUrlRegExp('http://localhost');
}
}
The problems are that I can't access the web app, I only get nginx homepage
And secondly my app trying to visit it just get's page not found.
Any help appreciated.
Solution was to create a new project with the dev-develop flag.
composer create-project laravel/laravel new dev-develop
For some reason Mink-Extension wasn't working correctly for me without the flag

How to connect to Elasticsearch with Docker Compose

I connect from my web app to an Elasticsearch instance using the Java API:
static Optional<Client> getClient(String hostName, int port) {
return getHost(hostName).map(host -> TransportClient.builder().build()
.addTransportAddress(new InetSocketTransportAddress(host, port))
);
}
static Optional<InetAddress> getHost(String hostName) {
InetAddress host = null;
try {
host = InetAddress.getByName(hostName);
} catch (UnknownHostException e) {
LOG.warn("Could not get host: {}", hostName, e);
}
return Optional.ofNullable(host);
}
Before switching to Docker Compose, I started Elasticsearch using
docker run --net=my-network --name=myDb elasticsearch
and my web app using
docker run --net=my-network -p 8080:4567 me/myapp
and sure enough, I could connect to the database using getClient("myDb", 9300).
But now that I've switched to Docker Compose, I don't know how to connect to Elasticsearch. This is my current docker-compose.yml:
version: '2'
services:
my-app:
image: me/myapp
ports:
- "8080:4567"
networks:
- my-network
elasticsearch:
image: elasticsearch
networks:
- my-network
networks:
my-network:
driver: bridge
Understandably, this results in an UnknownHostException since I haven't set the hostname of my Elasticsearch instance in the docker-compose.yml.
How do I do that?
I had to set an alias:
elasticsearch:
image: elasticsearch
networks:
my-network:
aliases:
- myDb
Now I can connect to myDb on port 9300 when calling getClient("myDb", 9300) shown in the question.
