-# EGroupware development enviroment as Docker container
-
-The container and docker-compose.yml file in this directory are the most easy way to get a full development enviroment for EGroupware.
-
-### It defines and uses the following volumes:
-* sources: document root of the webserver, by default $PWD/sources subdirectory, can also be your existing document root
-* data: EGroupware stores it's files here, by default $PWD/data subdirectory, can also be your existing /var/lib/egroupware
-* db: volume for MariaDB (should be NOT a directory under Mac OS and Windows for performance reasons!)
-* sessions: volume for sessions, internal no need to change
-* sources-push: swoolpush sub-directory of sources
-* collabora-config: /etc/loolwsd for Collabora container, by default $PWD/data/default/loolwsd
-* rocketchat-uploads: Upload directory for Rocket.Chat, by default $PWD/data/default/rocketchat/uploads
-* rocketchat-dumps: Dump directory for MongoDB, by default $PWD/data/default/rocketchat/dump
-
-### It runs the following containers:
-* egroupware: php-fpm
-* egroupware-nginx: Nginx
-* egroupware-db: MariaDB
-* egroupware-push: PHP Swoole based push server
-* egroupware-watchtower: to automatic keeps the containers up to date
-* collabora: Collabora Online Office
-* rocketchat: Rocket.Chat
-* rocketchat-mongo: MongoDB for Rocket.Chat
-
-### Usage:
-```
-mkdir dev && cd dev
-wget https://raw.githubusercontent.com/EGroupware/egroupware/master/doc/docker/development/docker-compose.yml
-wget https://raw.githubusercontent.com/EGroupware/egroupware/master/doc/docker/development/nginx.conf
-mkdir sources data
-# edit docker-compose.yml to fit your needs eg.
-# ports to use for Nginx / the webserver, by default 8080 and 4443
-# xdebug port, default 9001 (NOT 9000!)
-# IDE host, default XDEBUG_REMOTE_HOST=docker.for.mac.localhost
-docker-compose up -d
-```
-* It will install EGroupware master and phpMyAdmin in egroupware / phpmyadmin subdirectory of sources volume, if not already there
-* Credentials for a new install can be found in data:egroupware-docker-install.log
-* Use the following to tail the webserver error.log
-```
-docker logs -f egroupware-nginx 2>&1 | sed "s/PHP message/\\$(echo -e '\n\r')PHP message/g"
-```
-
-### Docker Desktop for Mac notes
-* directories of volumes must be exported to Docker, by default only your home-directory is!
-* permissions of sources and data directory must be readable (sources writable) by your user, as Docker daemon runs as that user!
-* db volume must NOT be a directory, as the networked access from Docker VM to the Mac is to slow!
-
-### Docker Desktop for Windows notes
-* you can NOT use $PWD to reference the docker-compose directory, use the full path with forward slashes!
-* directories of volumes must be exported to Docker!
-* db volume must NOT be a directory, as the networked access from Docker VM to Windows is to slow!
-
-### Docker on Linux
-* permissions of sources and data directory must be readable (sources writable) by www-data user (#33)
