php-fpm Dockerfile and conf optimized for Nextcloud

The Nextcloud Docker images from hub.docker.com, either the official or the 3rd-party like linuxserver.io, use php with default configurations, which is not optimized to run a complicated and resource consuming application like Nextcloud in a production environment.

I integrated the recommended configurations from Nextcloud document with php:fpm-alpine as base image.

Please be aware, after build, the image has only php-fpm runtime environment, has no Nextcloud source code built-in. You have to download Nextcloud server package and extract into the mapped folder. See the below usage section.

1. build the image

$ git clone https://github.com/fishingsun/phpfpm-nextcloud-docker.git
$ cd phpfpm-nextcloud-docker
$ docker build -t php:7.4fpm-nc .

• If your local docker environment has no default bridge network, please add --network option;
• If you plan to upload the image into your docker hub repo, recommend to add your hub id and hub repo name in tag;
• for example:

$ docker build --network ipvlan -t hyscom/phpfpm:7.4-nextcloud .

After compiled successfully, the new image should be listed:

$ docker image ls

REPOSITORY          TAG                IMAGE ID           CREATED             SIZE
hyscom/phpfpm       7.4-nextcloud      97e8492c353d       5 minutes ago       267MB
php                 fpm-alpine         f2a53c8e8392       2 days ago          71.4MB

2. use the image

Create the working folder:

$ sudo mkdir -p /srv/phpfpm-apps/nextcloud-data

Download nextcloud server package, and extract to /srv/phpfpm-apps:

$ wget https://download.nextcloud.com/server/releases/nextcloud-18.0.3.tar.bz2
$ sudo tar jxf nextcloud-18.0.3.tar.bz2 -C /srv/phpfpm-apps

Change the folders ownership:

$ sudo chown -R www-data:www-data /srv/phpfpm-apps

Please make sure the host has user www-data and group www-data, and their UID and GID are 33.

Run container:

$ docker run --name phpfpm --restart unless-stopped \
    --network ipvlan --ip=192.168.0.204 -v /srv/phpfpm-apps:/var/www/html \
    -d hyscom/phpfpm:7.4-nextcloud

Of course, you need a reverse proxy, pointing to 192.168.0.204:9000 in the above example case. Recommend Caddy or Nginx.

Recommend to use an independent database server to replace the built-in SQLite due to performance concern, for example, MariaDB.
