+IoBroker for Docker is a ready to use Docker image for ioBroker IoT platform (http://www.iobroker.net).

-IoBroker for Docker is an Dockerimage for ioBroker IoT platform (http://www.iobroker.net).
+It was originally created for a Synology Disk Station 1515+ with DSM 6 and official Docker package installed but should run on any other Linux based Docker host too.

-It is originally made for and always tested on a Synology Disk Station 1515+ with DSM 6 and official Docker package installed. But it also works on other systems with Docker installed!
+After more than three years of development it might be the best documented and still maintained Docker image for running ioBroker IoT platform with Docker.

-Version 4 now supports running the Image in Docker on the following architectures: amd64, armv7hf, aarch64.
-Feel free to ask for more architectures by opening an github issue.
+Since v4.0.0 the image is available for the following architectures: amd64, armv7hf, aarch64.<br>
+If you need more please let me know by opening a Github issue.

 ## Important notice

-The new v4 comes again with a new major node version (node10)!
-If you are updating an existing installation you have to perform some additional steps inside ioBroker!
-After upgrading your iobroker container you have to call "npm rebuild" or "reinstall.sh" (when js-controller > v1.5 "reinstall.js") for recompileing your installation for the use with node10!
-For more details please see official ioBroker documentation: [EN](https://www.iobroker.net/#en/documentation/install/updatenode.md) | [DE](https://www.iobroker.net/#de/documentation/install/updatenode.md).
-Make backup first!
+In general a new major version (e.g. v2, v4, v5) of the image comes with a new, preinstalled major node version!
+If you are updating an existing installation to a new major version (e.g. from v4 to v5) you have to perform some additional steps inside ioBroker! For more details please see official ioBroker documentation: [EN](https://www.iobroker.net/#en/documentation/install/updatenode.md) | [DE](https://www.iobroker.net/#de/documentation/install/updatenode.md).<br>
+
+You might avoid these procedure if you use my "Best practice" hint for "upgrading your ioBroker container".
+
+In any case make a backup first!

 ### Mounting folder/ volume

-It is 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 it is empty.
-Since v4.1.0 it is also possible mount a folder filled up with an iobroker backup file (created with backitup adapter) named like this: "iobroker_2020_01_06-01_09_10_backupiobroker.tar.gz".
-The startup script will detect this backup and restore it during the start of the container. Plese see container logs when starting the container for more details!

+
+The startup script will then detect this backup and restore it during the start of the container. Please see container logs when starting the container for more details!

 Note: It is absolutely recommended to use a mounted folder or persistent volume for /opt/iobroker folder!

 You can also mount a folder containing an existing ioBroker-installation (e.g. when moving an existing installation to docker).
-But watch for the used node version. If the existing installation runs with another major version of node you have do perform additional steps. For more Details see the "Important notice" on top.
+But watch for the used node version. If the existing installation runs with another major version of node you have do perform additional steps. For more Details see the "Important notice" on top of this readme.md file.

 **Important: If the folder you mount to /opt/iobroker in your container is placed on a mounted device, partition or other storage, the mountpoint on your host should NOT have the "noexec" flag activated. Otherwise you may get problems executing ioBroker inside the container!**   

-### Permission fixer
+### Mounting USB device

-After some issues with permissions related to the use of a dedicated user for ioBroker, I added some code for fixing permissions on container startup. This might take a few minutes on first startup. Please take a look at the container logs and be patient!
+If you want to use a USB device within ioBroker inside your container don´t forget to [mount the device](https://docs.docker.com/engine/reference/commandline/run/#add-host-device-to-container---device) on container startup and use the environment variable "USBDEVICES".

-### Userdefined startup scripts (advanced setting/ beta status)
+### User defined startup scripts

-In some cases it migth be helpful to add some script code to the startup script of the container. This is now possible by mounting an additional folder to the container and place a userscript in there.
-The folder containing your userscripts must be mounted under /opt/userscripts inside the container. If you mount an empty folder you will get two example scripts to be restored in that folder. Just try it out.
+It is possible to add some script code to container startup with the help of the userscripts feature. You can get this to work by mounting an additional folder to `/opt/userscripts` into the container.

-Basically there are two different scripts which will be read and called by the startup script. One that will only be called once at the first start of the container (userscript_firststart.sh) and one which will be called for every start of the container (userscript_everystart.sh).
+When you mount an empty folder the startup script will restore two example scripts in there. To activate the scripts you have to remove the `_example` part of the name. The "userscript_firststart.sh" will execute only at the very first start of a new container, while the "userscript_everystart.sh" will execute on every container start.

-Hint:
-To get familiar with that feature try the following: Create a Container, mount an empty folder to /opt/userscripts, start your container. Two scripts will be restored into the empty folder. Rename the example scripts by simply removing "\_example". Restart your container and take a look at the Log. In "Step 4 of 5: Applying special settings" you will see the messages generated by the example userscripts.
+Feel free to test it with my example code. Take a look at the log. In "Step 4 of 5: Applying special settings" you will see the messages generated by the example userscripts.
+
+### Multihost
+
+With the help of the ENV "IOB_MULTIHOST" and the ENVs for objects and states db connections (see ENVs table above) it is now possible to run a container as standalone, multihost master or multihost slave. This is more or less a feature for advanced users. Please make sure you know how ioBroker multihost is working and set the ENVs as with `ìobroker setup custom`.
+
+There is no need for executing `iobroker multihost enable` or `iobroker multihost connect` inside the container. Just configure the mentioned ENVs. The startup script will do all the magic.
+
+For general information about iobroker multihost feature please see [official ioBroker documentation](https://www.iobroker.net/docu/index-24.htm?page_id=3068&lang=de).
+
+### Healthcheck
+
+Since v5.1.0 the image contains a simple Docker healthcheck. At the moment it only checks if js-controller is running inside the container and reports "healthy" or "unhealthy" to the Docker daemon. Further development is planned.
+
+The healthcheck is configured to 5 retries in an 15s interval with a timeout of 5s. So a container needs a minimum of one minute to get unhealthy.   
+
+Hint: As the Docker daemon itself gives no opportunity to automatically restart an unhealthy container you might want to setup some kind of "watchdog container" like this simple one: https://github.com/buanet/docker-watchdog.
+
+### Maintenance script (beta)
+
+Within the implementation of the docker health check (above) some manual maintenance actions, like stopping ioBroker for upgrading js-controller, would cause the container to get "unhealthy" and may cause an external watchdog to automatically restart it.
+
+In this case you can use the new maintenance command line tool inside the container. By simply typing `maintenance on` it will activate some kind of "maintenance mode" and automatically stop ioBroker while the container stays healthy.
+
+After your maintenance is done just type `maintenance off`. Depending on the selected restart policy of your container, the command will stop (and automatically restart) it.
+
+## Best practices
+
+### Avoid using "latest" docker tag
+
+To avoid conflicts when upgrading your container or getting in trouble when accidentally upgrading your container to a new major version I prefer using a version docker tag like "v4.2.0" instead of "latest" for creating your container.
+
+With v5.1.0 an additional docker tag "latest-[major version]" is available. This gives you the possibility update your container automatically while always staying in the same major version.
+
+### Upgrading your container
+
+If you want to upgrade your ioBroker container to a new major version (e.g. from v4 to v5) I would prefer to do that by creating a backup in ioBroker (by "iobroker backup" or backitup adapter) and restoring it to a completely new container. All you need is time an the following steps:
+* make a backup by command line ("iobroker backup") or backitup adapter
+* stop the old container
+* create a new and empty data folder or volume and place your backup file in it
+* create a new container as your old or as you need it and use the new data folder/ volume for the /opt/iobroker mount point
+* follow the log output of the container and be patient
+
+After this steps the startup script inside the container will automatically detect and restore your backup to a new ioBroker instance. When iobroker is started after the restore it will install your adapters to the new ioBroker instance by itself. This might take some time but will give you the best and cleanest results...
