Fedora IoT Bootc Image Example with Podman Machine
This example walks through building and booting a Fedora IoT bootc image in a Podman machine.
This example is based on the Fedora bootc documentation about building scratch images; reference the upstream docs here for the latest version/information. |
To start, create a Containerfile.custom
with the following contents:
FROM quay.io/fedora-testing/fedora-bootc:rawhide-standard as builder RUN /usr/libexec/bootc-base-imagectl build-rootfs --manifest=fedora-iot /target-rootfs FROM scratch COPY --from=builder /target-rootfs/ / LABEL containers.bootc 1 ENV container=oci STOPSIGNAL SIGRTMIN+3 CMD ["/sbin/init"]
Initialize your Podman machine using the following command. You may skip this step if you already have a podman machine.
podman machine init
Grant your Podman machine the permissions necessary to run your Fedora IoT bootc image using:
podman machine set --rootful
Start your Podman machine using
podman machine start
Use the following command to build your fedora-iot
image:
podman -c podman-machine-default-root build --cap-add=all --security-opt=label=disable \ --device /dev/fuse -t localhost/fedora-iot -f Containerfile.custom .
After building the localhost/fedora-iot
image, you should be able to see it in your Podman machine’s list of images. Use the following command to check:
podman -c podman-machine-default-root images
The next step uses podman-bootc . If you need to install podman-bootc , please follow the instructions in the
podman-bootc repository
|
You’re now ready to boot a virtual machine using your new Fedora IoT bootc image. The command below will boot a VM in your current terminal window, allowing you to test everything that Fedora IoT bootc images have to offer:
podman-bootc run --filesystem=ext4 localhost/fedora-iot
