docker, wordpress and yaml_parse_file()

block34 · August 1, 2020

$ curl http://localhost:8000

The web page shows this thing:

Fatal error: Uncaught Error: Call to undefined function
yaml_parse_file() in /var/www/html/wp-content/plugins/mytest/main.php

Maybe I have to install the php-yaml extension (or something similar).
How you do it?

Here is my docker-compose.yml file:

version: '3.3'

services:
    db:
      image: mysql:5.7
      volumes:
        - dbdata:/var/lib/mysql
      restart: always
      environment:
        MYSQL_ROOT_PASSWORD: somewordpress
        MYSQL_DATABASE: wordpress
        MYSQL_USER: wordpress
        MYSQL_PASSWORD: wordpress

    wordpress:
         container_name: mytestplugin
         depends_on:
             - db
         image: wordpress:latest
         ports:
             - "8000:80"
         restart: always
         environment:
            WORDPRESS_DB_HOST: db:3306
            WORDPRESS_DB_USER: wordpress
            WORDPRESS_DB_PASSWORD: wordpress
         volumes:
             - .:/var/www/html/wp-content/plugins/mytest

volumes:

yaml_parse_file is documented in the online PHP Manual. It is part of the PECL yaml extension. There are instructions.

But to do it from inside docker?

I don't see instructions for doing it within Docker already written for you.

Do you understand how Docker images work? What Dockerfiles do? It would not be hard to take the regular installation instructions and port them to a Docker environment.

Non vedo le istruzioni per farlo all'interno di Docker già scritte per te.

Capisci come funzionano le immagini Docker? Cosa fanno i Dockerfile? Non sarebbe difficile prendere le normali istruzioni di installazione e portarle in un ambiente Docker.

I wrote on this forum just because I have this difficulty.
What else are the forums for?

If you don't ask a precise question then you might not get a precise answer.

Do you know exactly which WordPress image you're using? What OS is it based on? Debian does have a "php-yaml" package so if you use that one then you can probably set up your own Dockerfile that FROMs the base WordPress image and apt-installs the php-yaml package.

There are the desired info?

I don't know enough about the WP images to tell. I don't see anything OS-specific in there.

Check /etc for any "release" files.

Non so abbastanza delle immagini del WP da dire. Non vedo nulla di specifico del sistema operativo lì dentro.

Controlla / etc per eventuali file di "rilascio".

/etc?
However can you tell me exactly the commands to get the information you ask for?
