libfreetype6-dev
libjpeg62-turbo-dev
libpng-dev
&& docker-php-ext-install -j$(nproc) iconv
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/
&& docker-php-ext-install -j$(nproc) gd

What specific errors are you getting, using your Dockerfile installs gd and iconv just fine

Dockerfile

FROM php:7.2-fpm
RUN apt update && apt install -y --no-install-recommends \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libpng-dev \
    && docker-php-ext-install -j$(nproc) iconv \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd \
    && rm -r /var/lib/apt/lists/*

Closing as there isn't an issue with the image and your Dockerfile works fine if you escape the newlines
