I had the same problem a while ago. I started a container and typed the ext-install
command into this container. Once I found all the dependencies, I wrote them into the Dockerfile.
Example:
RUN apt-get update && apt-get install -y \
libmcrypt-dev \
&& docker-php-ext-install -j$(nproc) mcrypt
There is a dependency that libmcrypt-dev
needed before you can run docker-php-ext-install mcrypt
I’ve checked my older Dockerfiles and found something which might help you
