What's New in RancherOS v0.5.0

We’ve recently released v0.5.0 of RancherOS, the latest major release since v0.4.0. Since then, we’ve moved RancherOS out of an alpha state and made many changes to improve both stability and user experience. In addition to various bug fixes and support for Docker 1.11, v0.5.0 includes the following changes:

[Official Raspberry Pi Image]

[On our releases page you can now find an official Raspberry Pi image which is known to work on both Raspberry Pi 2 and 3. We’re especially excited about this since it offers users a cheap method of getting started with Docker and RancherOS. We’d like to thank the Hypriot][ team for their assistance on this feature.]

[Improved Build Process]

[Our build process has been refactored to support multiple architectures. With a given kernel, RancherOS can now be built for both ARM and ARM64 devices. In addition, the build process is now faster than it was previously which makes it easier than ever to create custom builds of RancherOS.]

[Console Switching without a Reboot]

[Switching to an alternate console can now be done without a reboot. The `ros console` subcommand was added to make this an easy process. The available consoles can be listed with `ros console list`. Ubuntu, Debian, Fedora, and CentOS consoles are currently available. The `ros console switch` command can be used to perform the switch.]

[Additional Configuration Options]

[Several additional cloud-config options were added.]

• [`console` - Sets the console container without having to add system services]
• [`resize_device` - Enables partition expanding with relying on a system service or network access]
• [`mounts` - Implements the cloud-init `mounts` key, which allows a set of mounts to be specified]
• [`sysctl` - Allows specifying sysctl settings]
• [`registy_auths` - Configures private registry and private image authentication for system services]

[Demo]

While the best way to check out these new features is to launch RancherOS, we’ve recorded a new demo that covers the basics of the operating system:

[Conclusion]

[This is an exciting release for us to bring to our community and users. It’s great to watch RancherOS as it becomes a more stable operating system for a variety of uses. As always, we are keeping to the philosophy that RancherOS should only include the minimum necessary to get Docker up and running.
