Call to undefined function Intervention\Image\Gd\imagejpeg()" - php

Question

I am using Laravel with the docker PHP:7.3-fpm image.
I get the issue Call to undefined function Intervention\Image\Gd\imagejpeg()" when using Image Intervention Package like this:
$avatar = \Image::make($image->getRealPath());
$avatar->fit(221, 146)->encode('jpg', 80);
Here is the full error message:
exception: Symfony\Component\Debug\Exception\FatalThrowableError^ {#8221

$quality: 80
}
}
Line 17 of Gd/Encoder.php is this:
imagejpeg($this->image->getCore(), null, $this->quality);
I found here that I should install GD with jpg / png support. However, the answer there was for the php:7.2-fpm-alpine image. Since I don't use the image, I can't apply it the apk add libjpg .. solution.
I also found here which uses the PHP:7.2-fpm image and claims to fix jpg issues.
I used
RUN apt-get install -y build-essential libssl-dev zlib1g-dev libpng-dev libjpeg-dev libfreetype6-dev
and
RUN docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install gd
from that solution, but I still get the above error. Here is my complete Dockerfile:

Any idea what could cause this?

Answer 1

This line was missing:
RUN docker-php-ext-install -j$(nproc) gd
So my final dockerfile looks like this:
FROM php:7.3-fpm
# Arguments defined in docker-compose.yml
ARG user
ARG uid
# Install system dependencies
RUN apt-get update && apt-get install -y \
build-essential \

libpng-dev \
libjpeg-dev \
libfreetype6-dev \
libonig-dev \

libicu-dev \
zip \
unzip \
libzip-dev \
-y mariadb-client
