Docker composer is in bin but not working

[brianroyce]

So, the composer does not work on Docker, and you can not install Symfony Transports. However, it is not working, and I cannot update the container. Would you happen to have any updates on this? I discovered this issue because I was trying to get Sendgrid set up. I was using Portainer to run this, but I can't get Symfony to install it.

For what it's worth this is where I am at on similar work:

You would create a new Dockerfile and set the docker-compose (if you're using compose) to build it

FROM mautic/mautic:5-fpm

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/bin --filename=composer

RUN apt-get update \
    && apt-get install --no-install-recommends -y \
    git \
    nodejs \
    npm

# install your symfony transport here
