Requirements

To run this you just need a docker and docker-compose.

Run

You can install a fresh instance of Nextcloud or restore your already installed cloud from dump/backup.

Fresh run

When you want to run fresh instance of nextcloud:

1. Create a .env file (use .env.dist as starter file, cp .env.dist .env) and setup values.
2. Run docker-compose up [-d].
3. Wait for download and build images.
4. Wait for install a fresh Nextcloud instance.
5. Goto NEXTCLOUD_HOST:NEXTCLOUD_PORT domain and play with your new cloud.

Run installed cloud

When you have a dump of your already installed Nextcloud instance:

1. Create a .env file (use .env.dist as starter file, cp .env.dist .env) and setup required values:
   • MYSQL_DATABASE (dbname),
   • MYSQL_PASSWORD (dbpassword),
   • MYSQL_USER (dbuser),
   • NEXTCLOUD_TRUSTED_DOMAINS (trusted_domains),
   • REDIS_HOST_PASSWORD (redis.password). They should have the same values as in config/config.php.
2. Move your database dump file(s) into initdb.d/ directory.
3. Move your config files into config/ directory.
4. Move your custom apps into apps/ directory.
5. Move your data files into data/ directory.
6. Move your nextcloud files into nextcloud/ directory.
7. Run docker-compose up [-d].
8. Wait for download and build images.
9. Wait when db service will load dump file(s) into the database. Note! When you goto the cloud before database is loaded you will got an error. Please be patient and wait for database.
10. Goto http://localhost/ domain and play with your new cloud.

Production

If you want to run production environment

1. Uncomment line #COMPOSE_FILE=docker-compose.yml:docker-compose.prod.yml in .env file. It tells to docker-compose to use those files instead of default docker-compose.yml and docker-compose.override.yml (they're good for development).
2. Rebuild images with docker-compose build [--pull].
3. Run new stack docker-compose up [-d].

Docker envs

NEXTCLOUD_HOST allow to change a host on which nginx services is listening. Default it's 127.0.0.1 so only you can connect from your local machine to the cloud. Setup 0.0.0.0 to allow others from the same network to connect to your cloud (for example to test cloud on your mobile).

Other environments are described here.

Log level

To "increase" performance you can set log level to error:

bin/occ log:manage --level=error

Improving Nextcloud Previews

According to this article Preview mechanism need some tuning.

Install Nextcloud app and setup recommended configurations:

bin/occ config:app:set previewgenerator squareSizes --value="32 256"
bin/occ config:app:set previewgenerator widthSizes  --value="256 384"
bin/occ config:app:set previewgenerator heightSizes --value="256"
bin/occ config:system:set preview_max_x --value 2048
bin/occ config:system:set preview_max_y --value 2048
bin/occ config:system:set jpeg_quality --value 60
bin/occ config:app:set preview jpeg_quality --value="60"

If you want to start from scratch you can delete preview folder:

rm -rf ./data/appdata_*/preview

And regenerate previews first time by:

bin/occ preview:generate-all -vvv

Full Text Search

To improve search result we can install:

• fulltextsearch
• files_fulltextsearch
• fulltextsearch_elasticsearch

We have to run elasticsearch service. Add :docker/elasticsearch/compose.yml to COMPOSE_FILE environment.

You can also change/setup other environments in .env file:

###> Elasticsearch ###
ELASTICSEARCH_IMAGE=extalion/nextcloud_elasticsearch
###< Elasticsearch ###

Goto settings, select Elasticsearch from select box, as an address type http://elasticsearch:9200 and setup index to nextcloud_index.

For first index run:

bin/occ fulltextsearch:index

Collabora online

If you want to run collabora online locally and you don't have a reverse proxy, you have to add nginx and collabora to your /etc/hosts:

127.0.0.1 collabora
127.0.0.1 nginx

For nextcloud (docker service) collabora is avaliable under collabora host and it has to be the same host for a client (your browser).

For collabora (docker service) nextcloud is avaliable under nginx host and you have to access nextcloud instance via http://nginx:$NEXTCLOUD_PORT.

---

We have to run collabora service. Add :docker/collabora/compose.yml to COMPOSE_FILE environment.

You can also change/setup other environments in .env file:

###> Collabora ###
COLLABORA_PORT=9980

# Go and read https://www.collaboraoffice.com/code/docker/and
# https://github.com/CollaboraOnline/online/blob/master/docker/from-packages/scripts/start-collabora-online.sh
# to see all env

COLLABORA_DICTIONARIES=en
# Value other then "set" will disable warning/info messages of LOKit
COLLABORA_SAL_LOG=set
# Value other then "set" won't generate ssl cert
COLLABORA_DONT_GEN_SSL_CERT=
COLLABORA_CERT_DOMAIN=collabora
# Collabora domain (without reverse proxy it's docker service)
COLLABORA_SERVER_NAME=collabora:9980
# Nextcloud domain (without reverse proxy it's docker service)
COLLABORA_DOMAIN=nginx
# Extra loolwsd command line parameter. To learn about all possible options,
# refer to the self-documented /etc/loolwsd/loolwsd.xml
#   docker-compose exec collabora cat /etc/loolwsd/loolwsd.xml
COLLABORA_EXTRA_PARAMS=--o:admin_console.enable=false --o:ssl.enable=false
# To enable the admin console feature of CODE remove admin_console.enbale option
# $COLLABORA_SERVER_NAME/loleaflet/dist/admin/admin.html
COLLABORA_USERNAME=root
COLLABORA_PASSWORD=CHANGE_ME
###< Collabora ###

Install richdocuments, goto settings, select Use your own server and as an url put http://collabora:9980.

Done!

Talk (STUN / TURN)

If you have install talk app and you want to "increase" performance and have video calls, you have to set up your own STUN/TURN server.

We have to run coturn service. Add :docker/coturn/compose.yml to COMPOSE_FILE environment.

You can also change/setup other environments in .env file:

###> Coturn ###
COTURN_IMAGE=extalion/nextcloud_coturn
COTURN_PORT=3478
COTURN_SECRET=CHANGE_ME
# Your nextcloud domain
COTURN_REALM=localhost
###< Coturn ###

Goto settings and set:

• STUN server to your-server-ip:$COTURN_PORT,
• TURN server to your-server-ip:$COTURN_PORT,
• TURN secret to $COTURN_SECRET.

Notify Push

To configure notify_push app:

• Install the notify_push app from the appstore,
• Restart nextcloud service (docker-compose restart nextcloud),
• set the url of the push server (bin/occ notify_push:setup http://domain/push)

If you got push server is not a trusted proxy then you have to add displayed proxies in config/config.php to trusted_proxies.

Reverse proxy

Basic nginx configuration for reverse proxy is avaliable here.

Update Server > Domain names and Reverse proxy > proxy_pass ports (read ports from your .env file).

Remove include nginxconfig.io/security.conf; from nextcloud domain conf. Docker nginx service conf is build base on Nextcloud example.

In .env file you have to change:

NEXTCLOUD_TRUSTED_DOMAINS=nextcloud.example.com
COLLABORA_CERT_DOMAIN=collabora.example.com
COLLABORA_SERVER_NAME=collabora.example.com
COLLABORA_DOMAIN=nextcloud.example.com

If you have install nextcloud already, in ./config/config.php:

• add nextcloud.example.pl to trusted_domains array,
• change overwrite.cli.url to nextcloud.example.pl.

If you have setup collabora online, you have to update URL (and Port) of Collabora Online-server to collabora.example.com.

Reload docker:

docker-compose up [-d]

Backup

To make a backup we're using a docker-backup tool which use BorgBackup under hood.

Create a .docker-backup file (use .docker-backup.dist as starter file, cp .docker-backup.dist .docker-backup) and setup values. Refer to documentation.

Update / Deploy

Setup COMPOSE_FILE to docker-compose.yml:docker-compose.prod.yml. Also if you want to run other services (elasticsearch, collabora, coturn) add their compose.yml too. See here.

Update images names (.env *_IMAGE) which point to your hub.

Run:

docker-compose build --pull

If you didn't build images on the server run:

docker-compose push

On the server run:

docker-compose pull
docker-compose up -d

Debug

If you want to debug a cloud with xdebug:

• be sure you're running dev environment (and images),
• add/setup debug to XDEBUG_MODE,
• reload docker with docker-compose up -d.

Now you're ready to remote debugging.
