Welcome to the getting started guide for Fedora IoT, both this guide and Fedora IoT images are in the very early stages so please report any issues to the mailing list.
We currently support the x86_64 and aarch64 architectures, the components to support ARMv7 are being worked upon and will be added shortly.
The currently tested reference devices are as follows:
- x86_64 and aarch64 VMs
- Raspberry Pi 3 Model B and Raspberry Pi 3 Model B+
- Dragonboard 410c
Other devices should work but aren't being actively tested in the context of IoT. The list of supported reference devices will expand with time.
The images being created are currently 4 Gb in size. The current memory used for testing is 1 Gb of RAM although Fedora IoT base image should run with less but of course this limits the amount of container applications can be run on top of the Base OS.
Applying updates, upgrading to the latest nightly build
There's nightly image builds for x86_64 and aarch64 available here. The OSTree update deltas are available on CDN using the following command:
Setting up a Virtual Machine
The images generated are compressed raw disk images. They can be utilised both on physical devices and used as disks on a virtualisation platform. The images work without change on qemu/KVM.
On qemu/KVM the tools that can be used to run the image in a VM include Virtual Machine Manager, GNOME Boxes or virsh cli. These tools are available in most Linux distributions. Decompress the image as below and then create a new virtual machine and when asked for storage point the tool at the existing disk image.
$ xz -d [filename].raw.xz
Use with VirtualBox
The images we produce need to be converted to be used with VirtalBox. This can be done with the qemu-img command found in the qemu-img package.
$ xz -d [filename].raw.xz $ qemu-img convert -f raw [filename].raw -O vdi [filename].vdi
Setting up a Physical Device
You will need either a serial console or HDMI monitor with USB keyboard to get started with the initial set.
Create a mSD card for either of the above devices with the following command:
To install using arm-image-installer:
$ sudo dnf install -y fedora-arm-installer
To write the image out use the following:
$ sudo arm-image-installer Usage: arm-image-installer <options> --image=IMAGE - xz compressed image file name --target=TARGET - target board --media=DEVICE - media device file (/dev/[sdX|mmcblkX]) --selinux=ON/OFF - Turn SELinux off/on as needed --norootpass - Remove the root password -y - Assumes yes, will not wait for confirmation --version - Display version and exit --resizefs - Resize root filesystem to fill media device --addconsole - Add system console to extlinux.conf --addkey= - /path/to/ssh-public-key Example: arm-image-installer --image=Fedora-Rawhide.xz --target=Bananapi --media=/dev/mmcblk0 For list of supported boards please check SUPPORTED-BOARDS file.
For the Raspberry Pi Model 3 B/B+ use:
For the Dragonboard410c use:
XXX with the location of your media. It will be
mmcblkX depending on hardware.
xzcat Fedora-IoT-28-<BUILD ID>.aarch64.raw.xz | sudo dd status=progress bs=4M of=/dev/XXX
If you wish to use a serial console you'll need to configure it. Details for the Raspberry PI are here.
Initial Setup once the VM or Phyical device is running
There is currently a few issues with the initial-setup. It currently only allows you to create a standard user. Create a user and ensture to set the "Administrator" checkbox which will configure sudo access.
Once the initial setup dialog has completed you can login as the new user and sudo to root. If you wish to at this time you can set a root password, otherwise the root account remains locked (this is fine).
This issue is currently been tracked in RHBZ 1578930.
Enabling wireless support on the DB410c and Raspberry Pi
Both WiFi and Bluetooth support on either the 96boards DragonBoard 410c or the Raspberry Pi 3 Model B or B+ need support files for either the WiFi or Bluetooth to work well. To install the files run the following commands,
brcm-firmware for Raspberry Pi or
wcn36xx-firmware for the Dragonboard and reboot which will enable the various wireless support:
$ sudo curl https://fedora.roving-it.com/wireless.repo -o /etc/yum.repos.d/wireless.repo $ sudo rpm-ostree install brcm-firmware $ sudo systemctl reboot
$ sudo curl https://fedora.roving-it.com/wireless.repo -o /etc/yum.repos.d/wireless.repo $ sudo rpm-ostree install wcn36xx-firmware $ sudo systemctl reboot
Display the status of the currently running deployment
Add a layered package
rpm-ostree install <pkg-name>
Upgrade to the latest
Rollback to the previous tree
We currently ship the podman daemon as it's quite light weight and doesn't use a lot of resources. The commands are very similar to that of docker. Some sample commands are:
podman pull fedora podman images podman run -it --rm fedora /bin/bash
Podman has a lot of well written documentation and articles you can find a number of them at the following links:
