* Regenerate example Ignition using fcct v0.18.0 to produce Ignition
spec v3.4.0 as a followup to https://github.com/poseidon/matchbox/pull/1079
* Fix one profile example where a double escape isn't needed
* 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
* Add initrd=main karg directive for UEFI (ignored by BIOS)
* Update Butane config version to v1.4.0 (generates Ignition v3.3.0)
in `fedora-coreos` and `fedora-coreos-install` examples
* Update virt-install flag --os-variant
* Removed virt-install deprecated flag --os-type
* Remove virt-install QEMU/KVM event preserve since it apparently
wasn't implemented anyway and QEMU/KVM now warns about it
* Remove serial consol kernel argument from examples, but still
mention it in docs
Rel:
* https://github.com/coreos/fedora-coreos-docs/pull/282
* https://www.spinics.net/linux/fedora/libvir/msg222078.html
We still support passing the rootfs image as an appended initrd, but we
recommend using coreos.live.rootfs_url instead: it generally boots faster
and requires less RAM.
When coreos-installer is running from the live image, it no longer needs
a separate install image, since by default it installs from content
embedded in the live system.
* Update Fedora CoreOS live PXE and disk install examples to
Fedora 33
* Increase libvirt VM memory from 2GB to 3GB to support live
PXE example, which is mostly just for laptop examples/demos.
Reduce the VM count from 3 to 2 to compensate.
* Change `fedora-coreos.ign` to suggest using an ed25519 SSH
key since Fedora CoreOS 33 disables RSA SHA1 (256 is still ok
but most people won't know which they have)
* Refactor examples to boot provision minimal hosts
with Fedora CoreOS or Flatcar Linux
* Remove the etcd3 cluster example or other specific
kinds of hosts
* Update script get-fedora-coreos
* Remove script get-coreos
* Matchbox examples should be simple and educational to
show how to PXE provision machines into clusters. Today,
these goals are achieved well enough by the 3-node etcd
cluster example
* Several years ago, I put together examples PXE booting
Kubernetes clusters with Matchbox. That was before we wrote
Tectonic or Kubernetes was as popular as it is. Today, a
Kubernetes distro is a project in its own right. It no
longer makes sense to maintain (duplicate) a Kubernetes
distro as "an example" inside Matchbox.
* Matchbox is now used for Kubernetes cluster provisioning in
more organizations than ever. It backs the poseidon/Typhoon and
kinvolk/Locomotive distros. These both serve as great external
examples of using Matchbox to provision Kubernetes clusters
Attention: If you relied on Matchbox Kubernetes docs, you can
find a similar guide at https://typhoon.psdn.io/cl/bare-metal/
(same author). https://github.com/poseidon/typhoon/
* Add ipxe.efi to dnsmasq image's /var/lib/tftpboot directory
* Add initrd kernel argument respected only by UEFI
https://github.com/coreos/bugs/issues/1239
* Improve network-setup docs and scripts to cover UEFI clients
and to support launching UEFI QEMU/KVM clusters locally
* Reduce references to grub.efi flow, its not a happy path
* Static Kubernetes / rktnetes examples are no longer going to be
maintained by this repo or upgraded to Kubernetes v1.6. This is not
considered a deprecation bc the reference clusters are examples.
* Remove static Kubernetes cluster examples so users don't choose it
* Self-hosted Kubernetes (bootkube) is now the standard recommended
Kubernetes cluster configuration
* Add Profile 'args' field as a list of kernel args
* Deprecate 'cmdline' field map of kernel args
* Add missing console=tty0 console=ttyS0 kernel args
to all example clusters
* Show `virsh console nodeN` command for development
with local QEMU/KVM nodes
* Use the same k8s-controller and k8s-worker profiles
whether booting a live cluster or installing to disk
* Exta root=/dev/sda kernel arg during install is fine
* simple example just network boots CoreOS machines
* simple-install example just network boots and installs CoreOS
* Simple examples don't do much provisioning, except adding pubkeys
* Clusters which install to disk auto-update so this bump just
changes the "starting" version. Deployed alpha clusters should
already be using 1109.1.0.
* Update CoreOS version to get rkt 1.2.1->1.6.0 improvements
for running the kubelet wrapper in Kubernetes clusters
* Update CoreOS version for other clusters so users only need
to download one cached version of assets to run examples
