Yep – it’s necessary. I really need to dig into that page load; what’s happening in this evironment and why? It’s time to setup xdebug and webgrind.<\/p>\n\n\n\n

We’ll use the Geniem Oy’s images and repo<\/a> for the foundation. I’m specifically interested in the webgrind service, and will add this to my docker-compose.yml file:<\/p>\n\n\n\n

webgrind:\n  image: devgeniem\/webgrind\n  ports:\n    - 80\n  volumes_from:\n    - web<\/code><\/pre>\n\n\n\n
I will customize it a bit, so it fits my workflow, and I’ll make the UI available on port 8081;<\/p>\n\n\n\n
  webgrind:\n    image: devgeniem\/webgrind\n    labels:\n      - \"traefik.enable=true\"\n      - \"traefik.docker.network=traefik_proxy\"\n      - \"traefik.http.routers.${NAME}-debug.rule=Host(`debug.schoolupdate.c7`)\"\n      - \"traefik.http.routers.${NAME}-debug.tls=true\"\n    ports:\n      - 443:80\n    volumes:\n      - .\/debug:\/tmp\/xdebug<\/code><\/pre>\n\n\n\n
I then need to confirm or configure my own wordpress service and make the xdebug output dir is set. My WordPress service looks like this:<\/p>\n\n\n\n
  wordpress:\n    container_name: ${NAME}-wordpress\n    user: \"1000:1000\"\n    build:\n      context: \/home\/mklasen\/server-management\/config\/wordpress\n      dockerfile: wordpress.Dockerfile\n    depends_on:\n      - db\n    expose:\n      - \"9000\"\n    volumes:\n      - \/home\/mklasen\/server-management\/config\/php\/default.conf:\/usr\/local\/etc\/php\/conf.d\/php.ini\n      - .\/:\/var\/www\/\n      - .\/debug:\/tmp\/xdebug\n    links:\n      - db\n    external_links:\n      - catchall\n    environment:\n      PHP_AUTOCONF: \/usr\/bin\/autoconf<\/code><\/pre>\n\n\n\n
and the xdebug part of my php.ini (not all settings here are relevant):<\/p>\n\n\n\n
xdebug.client_host = localhost\nxdebug.mode = debug,develop,profile,trace\nxdebug.start_with_request = yes\nxdebug.client_port = 9003\nxdebug.idekey=VSCODE\nxdebug.cli_color=2\nxdebug.var_display_max_depth = 10\nxdebug.var_display_max_children = 256\nxdebug.var_display_max_data = 1024 \nxdebug.output_dir=\/tmp\/xdebug<\/code><\/pre>\n\n\n\n
Alright, let’s move ahead and restart the docker compose environment with:<\/p>\n\n\n\n
docker-compose stop && docker-compose up -d<\/code><\/pre>\n\n\n\n
Now, I did run into some issues like “NOTICE: PHP message: Xdebug: [Profiler] File ‘\/tmp\/xdebug\/cachegrind.out.*’ could not be opened.”<\/p>\n\n\n\n
This was related to the permissions the directory has. After running a chmod -R 777 debug<\/code> on my docker volume folder, this was resolved.<\/p>\n\n\n\n
Now, that’s all to really start understanding what’s going on in your PHP web applications,<\/p>\n\n\n\n
Happy developing!<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
