 # docker-iobroker
 Docker image for ioBroker (http://iobroker.net) based on debian:latest (http://hub.docker.com/_/debian/)
 
-This project creates a Docker image for running ioBroker in a Docker container. It is made for and tested on a Synology Disk Station 1515+ with DSM 6 and Docker-package installed. But it should also work on other systems with Docker!<br>
+This project creates a Docker image for running ioBroker in a Docker container. It is made for and tested on a Synology Disk Station 1515+ with DSM 6 and Docker-package installed. But it should also work on other systems with Docker (Normally I do a small additional test on my Debian-VM with Docker CE)!
-Cause the container ist based on debian:latest, it acts nearly like a full virtual machine. That makes it possible to easily add some additional dependies for some ioBroker-Adapters.
+
+## Important
+
+Switching an existing installation from docker-iobroker-image v1 to v2 or greater means switching iobroker itself from node6 to node8! This requires additional steps inside ioBroker! After upgrading iobroker-container you have to call "reinstall.sh" for recompiling your installation for the use with node8. For Details see official ioBroker-documentation (http://www.iobroker.net/docu/?page_id=8323&lang=de). Make backup first!!!
+
+At the moment v3.0.0 does no longer support running in host-mode on Synology-devices because of a kernel issue in actual DSM-kernel! Please use bridged or macvlan mode. For details see new tutorial linked in the following.

+## Special Settings
+
+In v3.0.0 I added some new features. The following will give some short information about that.
+
+### Environment Variables
+
+|env|value|description|
+|---|---|---|
+|PACKAGES|package1 package2 package2|seperateed by whitespace; will install the listed packages on startup<br>(be paitient, this may take some time!)|
+|AVAHI|true|will install and activate avahi-daemon for supporting yahka-adapter|
+|LANGUAGE|de_DE:de|following locales are pre-generated: de_DE:de, en_US:en|
+|LANG|de_DE.UTF-8|following locales are pre-generated: de_DE.UTF-8, en_US.UTF-8|
+|LC_ALL|de_DE|following locales are pre-generated: de_DE.UTF-8, en_US.UTF-8|
+|TZ|Europe/Berlin|all valid Linux-timezones|
+
+### Mounting Folder/ Volume
+
+It is now possible to mount an empty folder to /opt/iobroker during first startup of the container. The Startupscript will check this folder and restore content if empty.
+
+It is absolutely recommended to use a mounted folder or persistent volume for /opt/iobroker folder!
+
+This also works with mounting a folder containing an existing ioBroker-installation (e.g. when moving an existing installation to docker). 
+
+### Permission Fixer
+
+I added some code for fixing permissions for new iobroker-user. Permission-fixing is called on first start of the container. This might take a few minutes. Please be patient!
