Description
I've been trying to set this up for days: https://opentelemetry.io/docs/zero-code/php/.
Here's my dockerfile for PHP, built with docker build --platform linux/amd64 -t phpbox -f dockerfile .:
FROM --platform=linux/amd64 php:8.3.13-alpine3.20
RUN apk add unzip git curl autoconf gcc g++ make linux-headers zlib-dev file
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
RUN pecl install excimer
RUN pecl install opentelemetry && docker-php-ext-enable opentelemetry
RUN composer require slim/slim:4.14 slim/psr7 nyholm/psr7 nyholm/psr7-server laminas/laminas-diactoros open-telemetry/sdk open-telemetry/opentelemetry-auto-slim open-telemetry/opentelemetry-auto-psr18 open-telemetry/exporter-otlpand index.php
<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;
require __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->get('/', function (Request $request, Response $response, $args) {
$response->getBody()->write("Hello world!");
return $response;
});
$app->run();and my Docker commands:
docker run --rm -v ".:/app" -w "/app" phpbox sh -c "composer require slim/slim:4.14 slim/psr7 nyholm/psr7 nyholm/psr7-server laminas/laminas-diactoros open-telemetry/sdk open-telemetry/opentelemetry-auto-slim open-telemetry/opentelemetry-auto-psr18 open-telemetry/exporter-otlp"
docker run --rm -p "8000:8000" -v ".:/app" -w "/app" phpbox sh -c "env OTEL_PHP_AUTOLOAD_ENABLED=true OTEL_SERVICE_NAME=app OTEL_TRACES_EXPORTER=otlp OTEL_EXPORTER_OTLP_PROTOCOL=grpc OTEL_EXPORTER_OTLP_ENDPOINT=http://jbox:4317 OTEL_PROPAGATORS=baggage,tracecontext OTEL_LOGS_LEVEL=debug php -S 0.0.0.0:8000"and I get this error:
