Error to run dump-sql.php

[brunocriado]

I'm trying to run that app inside a docker container but I'm getting an error.

My dockerfile:

FROM php:7.2.7-apache

# SERVICE php application

RUN apt-get update
RUN apt-get install -y mysql-client

ENV DEBIAN_FRONTEND noninteractive
ENV PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

COPY css /var/www/html/css
COPY img /var/www/html/img
COPY includes /var/www/html/includes
COPY js /var/www/html/js
COPY node_modules /var/www/html/node_modules
COPY index.html package.json todo.php /var/www/html/

RUN docker-php-ext-install mbstring pdo pdo_mysql mysqli

RUN chown -R www-data:www-data /var/www/html \
    && a2enmod rewrite

It's enabled to store data in mysql and all others changes that you mentioned in README.

root@todo:/var/www/html/includes# php dump-sql.php 

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /var/www/html/includes/mysql-db.php:99

Same via browser.
