PDO is not installed about docker-php-nginx

[jordie23]

There's a new issue since the user is changed to nobody now. I found this works though (for anyone stumbling upon this thread):

FROM trafex/alpine-nginx-php7
USER root
RUN apk --no-cache add php7-pdo_mysql
USER nobody

I also tried to install PDO by adding this line RUN apk add --no-cache php7-pdo php7-sqlite3 to my Dockerfile, but it doesn't work. Perhaps, I've the files 00_pdo.ini and 00_sqlite3.ini inside /etc/phpp6/conf.d

I think it could be a good idea to add PDO directly in the project Dockerfile. This library is really often used..

Thanks

I finally make it work! It was a bit tricky but here's my Dockerfile :

FROM trafex/alpine-nginx-php7
RUN rm -rf /var/www/html/*

RUN apk add --no-cache php7-pdo php7-sqlite3 php7-pdo_sqlite

WORKDIR /var/www/html
COPY app/ /var/www/html/

For MySQL, simply add php7-pdo_mysql, not simply php7-mysql ... !

Hope it'll help you.

Yes that should do it! 👍
Although you don't need to add the dependencies yourself (like php-7-pdo and php7-sqlit3). You can just add one of these packages: https://pkgs.alpinelinux.org/packages?name=php7-pdo_*&branch=edge&arch=x86_64 to include the desired database API.

This example Dockerfile already includes php7-mysqli to communicate with a database so I will not add PDO to it as well. If you want to use PDO; add the right package to the Dockerfile and remove php7-mysqli.

If you're not sure what API to use for talking to the database, see this comparison: http://php.net/manual/en/mysqlinfo.api.choosing.php
