从Docker容器添加到php的扩展

I'm using Arch Linux os.

I have a container running a php project and I need to have gmp and curl extensions enabled.

My container is based from an Alpine image and I can install the extensions using docker exec {container-name} apk add php-gmp php-curl.

Then if I run docker exec {container-name} php -m to display my extensions the console prints gmp and curl. Great this is all good, I also have the extensions enabled in the php.ini file running inside the same container.

But if I go to a controller and return extension_loaded('gmp') it prints false!

What am I missing?

    Shout out to Jon Stirling for his answer.

    I needed to re-edit the Dockerfile to include the gmp and curl packages and then also had Dockerfile edit the php.ini config file to include the gmp and curl extensions as well.

    So:

    RUN apk add --no-cache \

    ...{all my other packages}...

    php-gpm \

    php-curl

    RUN sed -i 's/extension=gmp.$/extension=gmp/;s/extension=curl.$/extension=curl/;' /etc/php7/php.ini

    The last line uses the terminal tool 'sed -i' to replace any lines that match extension=gmp and extension=curl and replaces the whole line that they're on.

    This basically un-comments them from the php.ini file without having to copy a whole new php.ini file from the directory.

    After rebuilding the whole project using docker-compose build then starting everything up again extension_loaded('gmp') returned true!
