I need to install the mysqli and zip extensions in a Docker image, use the Dockerfile file to run the installation in my instances but with no results.
this is my Docker file file:
FROM php:5.6-fpm
RUN docker-php-ext-install mysqli mysqlnd pdo pdo_mysql zip
and this is the error that my website shows:
Fatal error: Call to undefined function mysqli_connect() in /var/www/html/classes/ConnectionFactory.php on line 17
TL; DR
The image that you posted could not be built, correcting the errors I got, I came to this image that does work:
FROM php:5.6-fpm
RUN apt-get update && \
apt-get install -y --no-install-recommends \
zlib1g-dev && \
docker-php-ext-configure pdo_mysql --with-mysql=mysqlnd && \
docker-php-ext-configure mysqli --with-mysqli=mysqlnd && \
docker-php-ext-install mysqli pdo pdo_mysql zip && \
apt-get clean && \
rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*
NOTE: The last two lines are to try to reduce the image space.
Long version I tried to build the image you posted and I get the following error:
+ cd /usr/src/php/ext/mysqlnd
+ phpize
Cannot find config.m4.
Make sure that you run '/usr/local/bin/phpize' in the top level source directory of the module
If we look at the documentation of MySQL Native Driver we see that it says:
5.4.0 The MySQL Native Driver is now the default for all MySQL extensions (ie, mysql, mysqli and PDO_MYSQL). Passing mysqlnd to the configuration is now optional.
And further down on the same page it says:
MySQL database extensions must be configured to use the MySQL Client Library. In order to use the Native MySQL driver, PHP needs to be compiled specifying that the MySQL database extensions are compiled with the Support for the MySQL Native Driver.
And it also indicates how to compile the extensions, that is, we can remove the package mysqlnd and we need to indicate that the extensions mysqli and pdo_mysql are compiled with the MySQL Native Drive.
For the latter you can use docker-php-ext-configure .
If I add the necessary lines to configure the packages, then I get the error that it does not find zlib to compile the zip extension:
checking libzip... no
checking for the location of zlib... configure: error: zip support requires ZLIB. Use --with-zlib-dir=<DIR> to specify prefix where ZLIB include and library are located
So it would be lacking to install the package zlib1g-dev to compile zip . Adding the installation of the package and then cleaning the packages, I get to the image above.
