Loading comments If your fleet uses a single container, it will be run in privileged mode by default and will have access to hardware in the same way as a vanilla Linux system.
It's actually pretty easy. Have a look at the network setup section of our documentation. In general, most network configurations can be achieved by changing the NetworkManager configuration file.
We had a number of reasons for doing this:. However, we've heard from users that they would still like to be able to SSH into the host OS on their devices, so we decided to add that capability starting with balenaOS version 2.
This gives you access to logs and tools for services that operate outside the scope of your container, such as NetworkManager, Docker, the VPN, and the supervisor. For more details, please check out this documentation. However, when a device is restarted or power cycled the container is not recreated, meaning all the data that was present in the container's filesystem before, remains. It's very important not to rely on this behavior, as containers are recreated on release updates, when environment variables are changed in the UI or API, or when a fleet restart is requested.
Persistent data is specific to a fleet. If you move devices between fleets running different code, then keeping persistent data from the old fleet could potentially cause issues.
On devices running balenaOS versions before 2. Newer balenaOS versions automatically purge named volumes when a device is moved to a new fleet. In fact there are multiple services running on the cloud and the devices communicate with some of them. On the device we run our agent in a Docker container, like user-deployed containers. We use certificates to authenticate the server to the client and API keys to authenticate the client to the server. There isn't any. The update process currently depends on the size of the update and the speed of the Internet connection.
The size of the update is currently the size of the Docker layers that differ between the Docker image on the device and the Docker image of the newly pushed code.
We currently have a delta-mechanism , which calculates binary difference between two images, which will drop the update size significantly, even on cases where no Docker layers are shared. If you are interested in testing this out, check out the delta updates documentation. The OS image you download from the UI has embedded credentials that allow the device to join your fleet without user input on boot.

Document CLI commands that are compatible with open-balena docs 17 opened Nov 7, by dfunckt. Hello, dear readers,. Keep on adding devices to open fleets or creating your own fleets-- all the feedback helps us improve balenaHub for everyone. This month, hear the balena origin story from our Founder, and check out the freshly updated balenaSense v2. Listen now. Powered by balenaBlocks, get a closer look at the improved balenaSense v2 and how it removes the friction from setting up environmental sensors and tracking and collecting their data.
