* 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
* Emphasize that Container Linux Configs have been dropped and
that Butane is the way forward to use modern Ignition v2
* Include some links to Flatcar Linux docs
* Update Makefile and docs for v0.10.0 release process
* Recommend preparing Ignition configs external to Matchbox (e.g.
with Terraform poseidon/terraform-provider-ct)
* Document that Matchbox Rendering is discouraged
* Add Butane Config support as a replacement for dropping Container
Linux Config support. Perform Matchbox Go template evaluation,
translation to Ignition, and parsing to a forward compatible version
* Deprecate rendering Container Linux Configs
* Use tools like [poseidon/ct](https://github.com/poseidon/terraform-provider-ct) or
[butane](https://coreos.github.io/butane/getting-started/) to validate and convert a
Butane Config (`focs` or `flatcar`) to Ignition (for Matchbox to serve)
* Please migrate to serving CoreOS Ignition directly, the Container
Linux related HTTP and gRPC endpoints will be removed in future
* Update Terraform examples to use Terraform v0.13
* Refresh examples to show Fedora CoreOS and Flatcar Linux
* Remove the etcd3 example, not worth it to maintain
* 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 is published as a binary or container image,
not planning to resume RPM/Copr publishing since its a
pain
* Publishing to Copr repo stopped in v0.6 (3 years ago)
* 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
* Travis creates a Go v1.13.4 environment, checks out the source
repo, and _then_ executes the `install` block to install `golint`
* With module-aware Go, this means installing `golint` caused a
diff, before the Matchbox `make` target was invoked. Builds were
correctly identified as "dirty" as a result
* Release tags v0.8.1 and v0.8.2 have been removed to avoid any
confusion. Container images with binaries considered dirty have
been removed as well
* 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
* Matchbox has moved to a new home in Poseidon
* Update Makefile so container image name uses
poseidon instead of coreos
* Publish container images to quay.io/poseidon/matchbox
* Render Container Linux Configs referenced in Profiles
as Ignition v2.2.0 documents.
* Recall, configs suffixed with .ign/.ignition will be
served as-is, as raw Ignition. Parse warnings will be
shown
* Serve Ignition configs (ending in .ign/.ignition) with v2.1
or v2.2 formats (previously, configs above v2.1 produced warnings
that the config was too new)
* Define the required versions of terraform-provider-matchbox
and terraform-provider-ct, with install instructions
* Refresh the tutorial for using Matchbox to PXE boot local
QEMU/KVM machines (using Terraform as a client)
* Starting in Go 1.7, the standard library http.Request includes
a Context for passing request-scoped values between chained handlers
* Delete the ContextHandler (breaking, should not have been
exported to begin with)
* Users should deploy the Container Linux Update Operator to coordinate
reboots of Container Linux nodes in a Kubernetes cluster
* Write cluster addon docs to describe CLUO
* Terraform modules `bootkube` and `profiles` (Kubernetes) disable
