Installing Fedora CoreOS on VirtualBox on Windows 10
Raw
fedora_coreos-virtualbox-windows10.md

  • Download and install VirtualBox.

  • Download the Fedora CoreOS ISO

  • Create a new VM in VirtualBox

    • For the OS, Other Linux, 64-bit should be fine
    • Give the VM at least 2GB (depending on your physical memory).
    • Create a disk of whatever size you want. I made a VMDK file that could expand dynamically up to 50GB.

  • Mount the ISO in the VM

    • Right click on the VM and click settings
    • Go to the Storage tab
    • Click on the empty disk on the left
    • Click the disk icon next to IDE Secondary on the right
    • Choose the ISO
    • Check the Live CD/DVD box
    • Go to the Network tab
    • Make sure Bridge is selected

  • Start the VM. It should boot into CoreOS to a core@localhost prompt.

  • Run sudo fdisk -l. You should have a /dev/sda device. That's the VM's disk.

  • Create an Ignition file. (If you are unsure how to do that, check the Fedora Docs.)

  • Upload your Ignition file to an HTTP server somewhere that the VM can access.

  • Make sure your network adapter within the VM is enabled/configured (sudo nmcli or sudo nmtui).

  • Use curl to download your Ignition file to the VM.

    • curl <url to ignition file> > <file name>.ign

  • Use coreos-installer to install to the VM's disk with your keys:

    sudo coreos-installer install /dev/sda --ignition-file <path to .ign file> --copy-network

  • Shut down the VM: shutdown now.

  • Edit the VM settings again and remove the ISO from the machine.

  • Power it up again. You should end up at a login prompt displaying an assigned IP address.

  • SSH into the VM by using that IP address:

    PS C:\Users\user> ssh core@<ip address>
The authenticity of host '<ip address> (<ip address>)' can't be established.
ECDSA key fingerprint is SHA256:...
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '<ip address>' (ECDSA) to the list of known hosts.
