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
* Use our own infra to perform image builds and push images.
Provides future options for publishing images to multiple
image registries and for multiple architectures, while keeping
push permissions in-house
* Remove Travis ability to push to Quay
* Use Travis only for Go tests of Pull Requests
* Use `quay.io/dghubble/protoc` as the standard codegen
environment across projects. Pin a version (v3.10.1)
* Generated code is now automatically ignored by golint
based on the comment header, which will simplify linting
* Upgrade protobuf from 2bba0603135d to v1.3.2
* Upgrade grpc from v1.2.1 to v1.25.1
* Remove `get-protoc` and `codegen` scripts
* rkt achieved its mission creating the OCI standard,
pluggable runtimes, and prevented Docker world
domination. We can now proceed with disarmament
* Few, if any, developers still use rkt locally
* Local QEMU/KVM tutorials use either docker or rkt/acbuild,
but they're dated. rkt and acbuild are no longer in mainstream
use since they successfully drove OCI standardization
* Remove the rkt examples, as they are just more difficult for
newcomers to use and seldom maintained at this point
* Retain Docker examples, although podman will likely supplant
all docker usage in future
* 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
In virt-install v1.4.2, the meaning of `--pxe` changed from "allow pxe
boot" to "always pxe boot." This breaks matchbox, since we expect hosts
to pxe-boot only with empty hds. On hosts with v1.4.2, the VMs loop,
re-installing CL over and over.
The flag isn't necessary anyways, since we pass `--boot=hd,network`,
which enables pxe-booting.
