The Docker Desktop for Windows user manual provides information on how to configure and manage your Docker Desktop settings. For information about Docker Desktop download, system requirements, and installation instructions, see Install Docker Desktop.

This page contains information about the Docker Desktop Stable release. For information about features available in Edge releases, see the Edge release notes. The Docker Desktop menu allows you to configure your Docker settings such as installation, updates, version channels, Docker Hub login, and more. This section explains the configuration options accessible from the Settings dialog.

On the General tab of the Settings dialog, you can configure when to start and update Docker. Automatically check for updates - By default, Docker Desktop automatically checks for updates and notifies you when an update is available.

Click OK to accept and install updates or cancel to keep the current version. You can manually update by choosing Check for Updates from the main Docker menu. You must use this option with caution as exposing the daemon without TLS can result in remote code execution attacks.

Send usage statistics - By default, Docker Desktop sends diagnostics, crash reports, and usage data. This information helps Docker improve and troubleshoot the application. Clear the check box to opt out. Docker may periodically prompt you for more information.

The Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources. Different settings are available for configuration depending on whether you are using Linux containers in WSL 2 mode, Linux containers in Hyper-V mode, or Windows containers. CPUs : By default, Docker Desktop is set to use half the number of processors available on the host machine.

To increase processing power, set this to a higher number; to decrease, lower the number. Memory : By default, Docker Desktop is set to use 2 GB runtime memory, allocated from the total available memory on your machine. To increase the RAM, set this to a higher number. To decrease it, lower the number. Disk image location : Specify the location of the Linux volume where containers and images are stored. You can also move the disk image to a different location.

If you attempt to move a disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it. The File sharing tab is only available in Hyper-V mode, because in WSL 2 mode and Windows container mode all files are automatically shared by Windows. Use File sharing to allow local directories on Windows to be shared with Linux containers. This is especially useful for editing source code in an IDE on the host while running and testing the code in a container.

Note that configuring file sharing is not necessary for Windows containers, only Linux containers. If a directory is not shared with a Linux container you may get file not found or cannot start service errors at runtime. See Volume mounting requires shared folders for Linux containers.

Shared folders are designed to allow application code to be edited on the host while being executed in containers. For non-code items such as cache directories or databases, the performance will be much better if they are stored in the Linux VM, using a data volume named volume or data container. This is not configurable. See Permissions errors on data directories for shared volumes.The vcgencmd linux command line tool can be used to send a broad range of commands to the VideoCore processor indeed the 'vc' stands for VideoCore.

The vcgencmd command is only available on Raspberry Pi hardwareand perhaps on other devices containing a Broadcom VideoCore processor. When the vcgencmd command cannot be executed, the node will inform you about this in multiple ways:. Remark: The documentation of the vcgencmd tool is not really sufficient to get started. For those who don't speak German, there is a 'translate' link in that page By sending a random input message to the input, the node will access via the vcgendcmd the processor to get the requested information.

As soon as the processor has returned the information, one or more output messages will be send containing that information:. The vcgencmd command offers a large amount of options on a Raspberry Pi, but we agreed on the Node-RED forum to reduce the number of options in this node. The following options are currently implemented in this node:.

Most of the throttling problems can be solved by using a better power supply. Remark: the vcgencmd command returns a bitwise pattern, in which every bit flag has its own meaning.

Since this is rather hard to interpret for most users, this node will convert the bit flags to human readable fields in the output message s : see the example output messages below When the hardware is throttled but there is no under-voltage, then you can assume over-temperature.

That assumption can be confirmed by using the "Get temperature" option. The hardware will switch automatically to another status, when the sensor measurements reach some criteria:. Example output message, in case the checkbox "Separate output messages per topic" is unselected:. Example output messages, in case the checkbox "Separate output messages per topic" is selected. A series of messages will be send:.

In most cases the 'core' temperature will be all you need, which is the core temperature of the BCM system-on-chip. Remark: when you only need to measure the temperature of your processor, you can also use my node-red-contrib-cpu node. That cpu-node has the advantage that it works on multiple platforms, so not only Raspberry Pi! This information is mainly useful for users that want to overclock their Raspberry PI. Note that these voltage levels are around 1,2V in normal conditions.

This in contradiction to the system board, which operates at voltage levels between 4,75V and 5,25V. All of these components have their own clock frequencies.

Moreover the GPU has adjustable clock frequencies for its subcomponents e. Shows the VideoCore firmware version. The output will be splitted automatically into an array of 3 strings. The latter one could be used to verify whether the power switch was succesfull. Use two separate nodes, one for activating the output and another one for deactivating the output:.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

For showing the raspberry temperature usually the vcgencmd is used. Directly under the Pi that works out of the box, but in the container the vcgencmd cannot be found.

Following the description for node-red-contrib-vcgencmd under 'Usage via Docker' several setups need to be configured in order to use the vcgencmd. But executing it gives an error:. Trim it if necessary to show what it says about vcgencmd Then if it shows the command. That's really disappointing DannyBoyKNI have added that feature at the time being, as it was requested in this issue. Perhaps if mikeS7 is reading this discussion, he might be able to help you. I don't use this in Docker myself!

Checked right now, confirmed it doesn't work. It was in time when Node-RED image was based on debian linux.

I solved it by using custom image with following in Dockerfile:. Or run a single bash command on the host outside to mqtt publish the data somewhere you can get it more easily Do I have to adapt something? Is there a problem with the base image?

Do I have to wait for changes? You should build your own image, in your case Dockerfile will looks like:. However, I removed the volume mapping and rebuild the container from the Dockerfile by adding as you wrote apk add --no-cache raspberrypi and restarted the container with no luck. DannyBoyKN You can't rebuild container, you should build image and use it in your compose file.

If your Jellyfin server does not support hardware acceleration, but you have another machine that does, you can leverage rffmpeg to delegate the transcoding to another machine. Currently Linux-only and requires SSH between the machines, as well as shared storage both for media and for the Jellyfin data directory. Hardware acceleration options can be found in the Admin Dashboard under the Transcoding section of the Playback tab. Select a valid hardware acceleration option from the drop-down menu, indicate a device if applicable, and check enable hardware encoding to enable encoding as well as decoding, if your hardware supports this.

The hardware acceleration is available immediately for media playback. No server restart is required. Each hardware acceleration type, as well as each Jellyfin installation type, requires different setup options before it can be used.

It is always best to consult the FFMpeg documentation on the acceleration type you choose for the latest information. In order to use hardware acceleration in Docker, the devices must be passed to the container. To see what video devices are available, you can run sudo lshw -c video or vainfo on your machine. Alternatively, you can use docker-compose with a configuration file so you don't need to run a long command every time you restart your server.

Edit sources. Update your package list again to download the latest software available from the new repository. When prompted to choose to keep or install the maintainer package file type y to install the maintainer version.

If you get driver information, everything is fine but if you get an error like couldn't find libnvidia-ml. Try to play any file needing a transcode by changing the bitrate. Add the Jellyfin service user to the above group to allow Jellyfin's FFMpeg process access to the device, and restart Jellyfin.

Otherwise you have to build from source. Verify iHD driver using vainfo.If you want to get really adventurous, you could try betting with Bitcoin. Bitcoin has a long relationship with gambling, since you can use it relatively anonymously online.
