Dalton Hubble e59b2b7b55 Update Flatcar Linux examples and use Ignition

* Discontinue using Matchbox's Container Linux Config features
* Flatcar Linux OS now supports Ignition v2.13+ which means it
can accept Ignition v3.x spec's, like Fedora CoreOS. Matchbox
supports this by serving Ignition documents directly
* Users of the poseidon/matchbox Terraform provider can pass
a `matchbox_profile` `raw_ignition` contents with the desired
Ignition v3.3 spec
* Users of the poseidon/ct Terraform provider can write Butane
Config YAML, perform templating, and render an Ignition document
using either the fcos or the flatcar variant

Examples

Matchbox automates network booting and provisioning of clusters. These examples show how to use Matchbox on-premise or locally with QEMU/KVM.

Terraform Examples

These examples use Terraform as a client to Matchbox.

Name	Description
fedora-coreos-install	Fedora CoreOS disk install
flatcar-install	Flatcar Linux disk install

Customization

Look through the examples and Terraform modules and use them as a starting point. Learn more about matchbox.

Manual Examples

These examples mount raw Matchbox objects into a Matchbox server's /var/lib/matchbox/ directory.

Name	Description	FS	Docs

SSH Access

For Fedora CoreOS, add an SSH authorized key to the Butane Config (ignition/fedora-coreos.yaml) and regenerate the Ignition Config.

variant: fcos
version: 1.4.0
passwd:
  users:
    - name: core
      ssh_authorized_keys:
        - ssh-ed25519 SET_PUBKEY_HERE

podman run -i --rm quay.io/coreos/fcct:release --pretty --strict < fedora-coreos.yaml > fedora-coreos.ign

For Flatcar Linux, add an SSH authorized key to the Butane config (ignition/flatcar.yaml or ignition/flatcar-install.yaml) and regenerate the Ignition Config.

variant: flatcar
version: 1.0.0
passwd:
  users:
    - name: core
      ssh_authorized_keys:
        - ssh-ed25519 SET_PUBKEY_HERE

podman run -i --rm quay.io/coreos/fcct:release --pretty --strict < flatcar.yaml > flatcar.ign
podman run -i --rm quay.io/coreos/fcct:release --pretty --strict < flatcar-install.yaml > flatcar-install.ign
