![]() If you would like to replace the balena logo with your own custom splash logo, then you will need to replace the splash/balena-logo.png file that you will find in the first partition of the image (boot partition or resin-boot) with your own logo. On production mode, nothing is written to tty1, on boot you should only see the balena logo, and this will persist until your application code takes over the framebuffer. You can also set a custom hostname via the Supervisor API on device. If you don't set a custom hostname, the device will default to. Your device will then broadcast (via Avahi) on the network as my-new-hostname.local. HostnameīalenaOS allows the setting of a custom hostname via config.json, by setting "hostname": "my-new-hostname". For versions of balenaOS = 2.45.0 store a maximum of 32 MB of persistent logs in the data partition of the device. The logs can be accessed via the host OS at /var/log/journal. To persist logs on the device, enable persistent logging via the configuration tab in the balenaCloud dashboard, or prior to device provisioning setting the "persistentLogging": true key in config.json. In balenaOS, logs are written to an 8 MB journald RAM buffer in order to avoid wear on the flash storage used by most of the supported boards. To use SSH via cloudlink, you need to have an SSH key configured on your development machine and added to the balenaCloud dashboard. You may still access a production image by tunneling SSH through the cloudlink via the CLI (using balena ssh ) or the balenaCloud web terminal. Production mode disables passwordless root access, and an SSH key must be added to config.json to access a production image using a direct SSH connection. Warning: Development mode has an exposed Docker socket and enable passwordless root SSH access and should never be used in production. Note: Raspberry Pi devices don’t have Getty attached to serial by default, but they can be configured to enable serial in the balenaCloud Dashboard via configuration variables. Capable of entering local mode for rapid development of application containers locally.Getty console attached to tty1 and serial.Docker socket exposed on port 2375, which allows balena push / build / deploy, that enables remote Docker builds on the target device (see Deploy to your Fleet).Passwordless SSH access into balenaOS on port 22222 as the root user, unless custom ssh keys are provided in which case key-based authentication is used.Development mode enables a number of useful features while developing, namely: ![]() This can be later changed via developmentMode.ĭevelopment mode is recommended while getting started with balenaOS and building an application using the fast local mode workflow. Production modeīalenaOS can be downloaded in production or development mode. We look forward to working with the community to grow and mature balenaOS into an operating system with even broader device support, a broader operating envelope, and as always, taking advantage of the most modern developments in security and reliability. balenaOS v2 represents the combination of the learnings we extracted over those years, as well as our determination to make balenaOS a first-class open source project, able to run as an independent operating system, for any context where embedded devices and containers intersect. The first version of balenaOS was developed as part of the balena platform, and has run on thousands of embedded devices on balena, deployed in many different contexts for several years. There are many decisions, large and small, we have made to enable that vision, which are present throughout our architecture. With OS-level virtualization, as implemented for Linux containers, both those objections are lifted for Linux devices, of which there are many in the Internet of Things.īalenaOS is an operating system built for easy portability to multiple device types (via the Yocto framework and optimized for Linux containers, and Docker in particular. VMs and hypervisors have lead to huge leaps in productivity and automation for cloud deployments, but their abstraction of hardware, as well as their resource overhead and lack of hardware support, means that they are not suitable for embedded scenarios. The core insight behind balenaOS is that Linux containers offer, for the first time, a practical path to using virtualization on embedded devices. Improve this doc What is balenaOS? IntroductionīalenaOS is an operating system optimized for running Docker containers on embedded devices, with an emphasis on reliability over long periods of operation, as well as a productive developer workflow inspired by the lessons learned while building balena.
