I've been working on upgrading my local environment from 2.2.10 to 2.3.4, but can't figure out how to install the extra PHP modules for the new version (ie: sodium) using Docker. I was previously using PHP 7.1, but just rebuilt my containers with 7.3. They're up and running with no problem, but how do I go about adding the modules? I tried running sudo pecl install -f libsodium which I thought would work, but because sodium wasn't added to the php.ini file it wasn't able to pick it up. I haven't been able to even find the .ini file inside the container, and am really at a loss here. The next thing I tried was adding it into the PHP Extensions line in docker-compose.yml, but this seems to break the ability to even run bin/magento from inside the container. enter image description here

Fyi I'm new to magento and docker, so I might be missing something obvious here. Thanks in advance for any help

This is a bit hard to explain if you are new to docker

But essentially you need to add these components when you build the docker image

https://github.com/DominicWatts/docker-magento2/blob/master/php/src/7.3-fpm/Dockerfile

To build that docker image and push it to docker hub would do something like this

cd php/src/7.3-fpm

docker login

docker build -t domw/magento2-php:7.3-fpm ./

docker push domw/magento2-php:7.3-fpm

Then to use it in project docker compose

https://github.com/DominicWatts/docker-magento2/blob/cb96aca516e51a418db28b46f03723f336b74ccf/docker-compose.src.73.yml#L28-L39

  fpm:
    hostname: fpm.magento2.docker
    image: domw/magento2-php:7.3-fpm
    restart: 'always'
    ports:
      - 9000
    links:
      - db
    volumes:
      - ./magento:/var/www/magento
    env_file:
      - ./global.env

  • Hey thanks so much for the informative response. This might be a dumb question, but since the image I'm pulling is from magento, how can I edit the original Dockerfile to include the modules I need? Do I need to clone the full magento docker to my github, alter the Dockerfile, then pull from this repo?

  • Can I take a look at docker image?

  • Here is the docker-compose.yml: pastebin.com/mXzX30DW, and I'm also using a docker-compose.override.yml file: pastebin.com/8giPFvtK. I don't have access to the Dockerfile itself, which I think may be one of the problems?

  • First time I'm seen an official(ish) docker compose file. Where did you get that from or did you put that together yourself? I put together my own stack github.com/DominicWatts/docker-magento2 but mine is a fork of the meanbee solution. I just got mine working how I wanted it and added some quick steps and bits and pieces. Performance was a big thing for me but I started this on windows. Now using linux (debian). But it's not the fastest and always having to look at permissions. But good enough for dev. Any time need something I add to docker file and rebuild and push to dockerhub

  • Well you've blown my mind. All the source files are here github.com/magento/magento-cloud-docker/tree/develop/images/php
