Profil mon application avec conteneur Blackfire dans l'environnement Docker

Question

Aujourd'hui, j'essaie d'ajouter Blackfire à ma pile Docker! J'ai suivi la documentation Blackfire dédiée à l'implémentation de Docker, le conteneur est correctement paramétré mais je n'arrive pas à faire un premier profil de mon application.

Il s'agit d'une pile Symfony. J'ai un conteneur PHP-FPM, et un conteneur CLI où je lance des commandes. Un conteneur NGINX est le serveur Web.

Mon fichier docker-compose.yml est le suivant:

--- 
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" 

Mes variables d'environnement sont correctement configurés avec mon ID Blackfire.

J'essaie de faire mon profil avec la ligne de commande suivante:

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

Le résultat est:

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

Dans les deux PHP-FPM et CLI Dockerfiles, je mets les documentation instructions:

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 

EDIT: Après avoir déclenché la commande de profil, j'ai les journaux suivants dans mon PHP-FPM conteneurs et mes journaux app nginx:

Answer 1

Hum juste repéré, votre conteneur php-fpm n'a aucun lien avec le conteneur blackfire.

Answer 2

Comme vous remplacez le nom du conteneur de Blackfire, vous devez adapter les blackfire.agent_socket=tcp://blackfire:8707 paramètres correspondant nom du conteneur (par exemple: blackfire.agent_socket=tcp://my_app_blackfire:8707).
