Nextcloud with Docker

docker-compose for nextcloud fpm with mariadb and nginx proxy as well as self signed ssl

Getting started

Folders for mounting data must be created, read below how to do that. Next, copy all .env.example files to only .env extension and then edit each one with your settings.

WARNING

MariaDB and PHP-FPM are configured to run on server with 1 CPU (4 threads) and 16 GB of RAM. If your configuration differs, edit database configuration my.cnf and php configuration Dockerfile files. There is no general rule for performance tweaking so look for explanations elsewhere. In /var/pool is a huge BTRFS raid disk pool mounted on my server.

Before running

Values that are ought to be changed before running:

1. Update database passwords in db.env (default: password123)
2. Update domains in nginx.env (default: 127.0.0.1)
3. Update ssl certificates to match your domain name in sslcert.env (default: 127.0.0.1)
4. Update volume paths for each service in docker-compose.yml (default: /var/pool/nextcloud)
5. Update max upload size in proxy/uploadsize.conf and web/nginx.conf (default: 25 GB)

Running

Make sure docker volume paths exist in the host sytem. If the default configuration is used, a directory tree can be created with the following commands:

mkdir -p /var/pool/nextcloud/{db,data,certs,vhost,html,mail}
mkdir -p /var/ramdisk/{dbcache,rediscache}

Mount free ram as ramdisk for caching:

sudo mount -t tmpfs -o size=2048M tmpfs /var/ramdisk/dbcache
sudo mount -t tmpfs -o size=2048M tmpfs /var/ramdisk/rediscache

Save ramdisks to fstab file:

none /var/ramdisk/dbcache tmpfs nodev,nosuid,noexec,nodiratime,size=2048M 0 0
none /var/ramdisk/rediscache tmpfs nodev,nosuid,noexec,nodiratime,size=2048M 0 0

Running containers:

docker-compose build --pull
docker-compose up -d

Runing custom script

Custom script is automatically copied to app container image. It can be run by executing:

docker-compose exec --user www-data app docker-entrypoint-custom

Updating

docker-compose down

And repeat steps for running.

Troubleshooting

Problems I ran into:

Redis

Verify redis is being used:

docker-compose exec --user root redis redis-cli MONITOR

Trusted domains

Sometimes trusted domains are not picked up in app image. Peek in this file to verify:

docker-compose exec --user www-data app cat config/config.php
