在Docker环境中使用Blackfire容器来剖析我的应用程序

今天我正在尝试将Blackfire添加到我的Docker堆栈中！我遵循专用于Docker实现的Blackfire文档，容器设置正确，但我无法成功创build我的应用程序的第一个configuration文件。

这是一个Symfony堆栈。我有一个PHP-FPM容器，以及一个启动命令的CLI容器。 NGINX容器是networking服务器。

我docker-compose.yml文件如下：

 --- cli: container_name: my_app_cli build: cli volumes: - "./volumes/apps:/srv/apps" stdin_open: true tty: true environment: - PHP_EXTRA_CONFIGURE_ARGS=--with-ldap links: - mysql:mysql - redis:redis - rabbitmq:rabbitmq - web:web - blackfire:blackfire mysql: container_name: my_app_mysql build: mysql environment: - MYSQL_DATABASES=my_database - MYSQL_ROOT_PASSWORD=sgreat_password - MYSQL_HOST=localhost - MYSQL_PORT=33306 - MYSQL_USER=guest - MYSQL_PASSWORD=password - MYSQL_LOYALTY_DATABASE=my_database ports: # MySQL - "33306:3306" volumes: # Mysql - "./volumes/mysql:/var/lib/mysql" phpmyadmin: container_name: my_app_phpmyadmin image: nazarpc/phpmyadmin ports: # PHPMyAdmin HTTP - "8082:80" links: - mysql:mysql phpfpm: container_name: my_app_phpfpm build: phpfpm ports: - "9000:9000" environment: - PHP_EXTRA_CONFIGURE_ARGS=--with-ldap links: - mysql:mysql volumes: - "./volumes/apps:/srv/apps" blackfire: container_name: my_app_blackfire image: blackfire/blackfire environment: # Exposes the host BLACKFIRE_SERVER_ID and TOKEN environment variables. - BLACKFIRE_CLIENT_ID - BLACKFIRE_CLIENT_TOKEN - BLACKFIRE_SERVER_ID - BLACKFIRE_SERVER_TOKEN links: - web:web volumes: - "./volumes/apps:/srv/apps" ports: - "8707:8707" rabbitmq: container_name: my_app_rabbitmq image: rabbitmq:3.5-management volumes: - /var/lib/rabbitmq environment: RABBITMQ_USER: guest RABBITMQ_PASSWORD: guest ports: # rabbitmq management - "8085:15672" redis: container_name: my_app_redis image: redis environment: REDIS_PASSWORD: great_password volumes: - "./volumes/redis:/data" ports: - "32772:6379" web: container_name: my_app_web build: nginx environment: NGINX_ENABLED_VHOST: www.my_app.local extra_hosts: - "www.my_app.local:127.0.0.1" links: - phpfpm volumes: - "./volumes/apps:/srv/apps" - "./volumes/html:/usr/share/nginx/html" - "./volumes/logs/nginx:/var/log/nginx" ports: - "80:80" - "443:443"

我的环境variables正确设置与我的Blackfire ID。

我尝试使用以下命令行来configuration我的configuration文件：

 docker exec my_app_blackfire blackfire curl --proxy http://my_app_web:80 http://www.my_app.local/api/stores

结果是：

 Are you authorized to profile this page? No probe response, missing PHP extension or invalid signature for relaying agent.

在PHP-FPM和CLI Dockerfiles中，我都提供了文档说明：

 RUN version=$(php -r "echo PHP_MAJOR_VERSION.PHP_MINOR_VERSION;") \ && curl -A "Docker" -o /tmp/blackfire-probe.tar.gz -D - -L -s https://blackfire.io/api/v1/releases/probe/php/linux/amd64/$version \ && tar zxpf /tmp/blackfire-probe.tar.gz -C /tmp \ && mv /tmp/blackfire-*.so $(php -r "echo ini_get('extension_dir');")/blackfire.so \ && printf "extension=blackfire.so\nblackfire.agent_socket=tcp://blackfire:8707\n" > $PHP_INI_DIR/conf.d/blackfire.ini

编辑：触发configuration文件命令后，我有我的PHP-FPM容器和我的NGINX应用程序日志中的以下日志：

PHP-FPM

刚发现嗡嗡声，你的php-fpm容器没有任何链接到blackfire容器。

当您覆盖blackfire容器名称时，您需要调整blackfire.agent_socket=tcp://blackfire:8707参数以匹配容器名称（即： blackfire.agent_socket=tcp://my_app_blackfire:8707 ）。
