2019-03-21 23:41:25 -07:00
6dd2731046 Set cpu/memory resources requests/limits for some addons
* Set resource requests and limits for Grafana and CLUO
* Set resource requests for Prometheus, but allow usage
to grow since needs vary widely
* Leave nginx without resource requests/limits for now,
its typically well behaved
2019-03-20 00:15:08 -07:00
1feefbe9c6 Update Calico from v3.5.2 to v3.6.0
* Add calico-ipam CRDs and RBAC permissions
* Switch IPAM from host-local to calico-ipam
  * `calico-ipam` subnets `ippools` (defaults to pod CIDR) into
`ipamblocks` (defaults to /26, but set to /24 in Typhoon)
  * `host-local` subnets the pod CIDR based on the node PodCIDR
field (set via kube-controller-manager as /24's)
* Create a custom default IPv4 IPPool to ensure the block size
is kept at /24 to allow 110 pods per node (Kubernetes default)
* Retaining host-local was slightly preferred, but Calico v3.6
is migrating all usage to calico-ipam. The codepath that skipped
calico-ipam for KDD was removed
*  https://docs.projectcalico.org/v3.6/release-notes/

limit
2019-03-17 13:23:04 -07:00
bf97a45b9d Remove heapster manifests from addons
* Heapster addon powers `kubectl top`
* In early Kubernetes, people legitimately used and expected
`kubectl top` to work, so the optional addon was provided
* Today the standards are different. Many better monitoring
tools exist, that are also less coupled to Kubernetes "kubectl
top" reliance on a non-core extensions means its not in-scope
for minimal Kubernetes clusters. No more exceptionalism
* Finally, Heapster isn't that useful anymore. Its manifests
have no need for Typhoon-specific modification
* Look to prior releases if you still wish to apply heapster
2019-03-17 12:41:59 -07:00
3d6a6d4adb Re-add Kubelet metadata service dependency on DigitalOcean
* Restore the original special-casing of DigitalOcean Kubelets
* Fix node metadata InternalIP being set to the IP of the default
gateway on DigitalOcean nodes (regressed in v1.12.3)
* Reverts the "pretty" node names on DigitalOcean (worker-2 vs IP)
* Closes #424 (full details)

part of v0.12 readiness
2019-03-12 01:19:54 -07:00
9493ed3b1d Change default iPXE kernel/initrd download from HTTP to HTTPS
* Require an iPXE-enabled network boot environment with support for
TLS downloads. PXE clients must chainload to iPXE firmware compiled
with `DOWNLOAD_PROTO_HTTPS` enabled ([crypto](https://ipxe.org/crypto))
* iPXE's pre-compiled firmware binaries do _not_ enable HTTPS. Admins
should build iPXE from source with support enabled
* Affects the Container Linux and Flatcar Linux install profiles that
pull from public downloads. No effect when cached_install=true
or using Fedora Atomic, as those download from Matchbox
* Add `download_protocol` variable. Recognizing boot firmware TLS
support is difficult in some environments, set the protocol to "http"
for the old behavior (discouraged)

deec512c14 Resolve in-addr.arpa and ip6.arpa zones with CoreDNS kubernetes plugin
* Resolve in-addr.arpa and ip6.arpa DNS PTR requests for Kubernetes
service IPs and pod IPs
* Previously, CoreDNS was configured to resolve in-addr.arpa PTR
records for service IPs (but not pod IPs)

5066a25d89 Add links and clarifications in CHANGES for release 2019-03-02 11:26:12 -08:00
de251bd94f Update tutorials to prefer newer provider plugins over min version
* Minimum versions of Terraform provider plugins are enforced in
each module already. Its better to provide examples with newer
versions. Some folks don't update them
* Previously, tutorials showed the minimum viable version of each
terraform provider that might be used

2019-02-28 22:47:43 -08:00
8ae552ebda Update documentation for use with Ubiquiti EdgeOS
* Show creation of a PXE-enabled network boot environment when
using dnsmasq as the DHCP server
* Recommend TFTP be served from /config/tftpboot since /config
is preserved between firmware upgrades
* Recommend compiling undionly.kpxe from source to enable
TLS features
* Add a note that equal-cost multi-path service IP routing
(e.g. for ingress) requires EdgeOS v2.0. Previously, it was known
that TLS handshakes couldn't be completed with packet balacing.
I've verified this is no longer the case when using the v2.0
EdgeOS firmware, ECMP works as expected.

7f8572030d Upgrade to support terraform-provider-google v2.0+
* Support terraform-provider-google v1.19.0, v1.19.1, v1.20.0
and v2.0+ (and allow for future 2.x.y releases)
* Require terraform-provider-google v1.19.0 or newer. v1.19.0
introduced `network_interface` fields `network_ip` and `nat_ip`
to deprecate `address` and `assigned_nat_ip`. Those deprecated
fields are removed in terraform-provider-google v2.0
* https://github.com/terraform-providers/terraform-provider-google/releases/tag/v2.0.0

4294bd0292 Assign Pod Priority classes to critical cluster and node components
* Assign pod priorityClassNames to critical cluster and node
components (higher is higher priority) to inform node out-of-resource
eviction order and scheduler preemption and scheduling order
* Priority Admission Controller has been enabled since Typhoon
v1.11.1

ba4c5de052 Set the Google Cloud minimum CPU platform to Intel Haswell
* Intel Haswell or better is available in every zone around the world
* Neither Kubernetes nor Typhoon have a particular minimum processor
family. However, a few Google Cloud zones still default to Sandy/Ivy
bridge (scheduled to shift April 2019). Price is only based on machine
type so it is beneficial to opt for the next processor family
* Intel Haswell is a suitable minimum since it still allows plenty of
liberty in choosing any region or machine type
* Likely a slight increase to preemption probability in a few zones,
but any lower probability on Sandy/Ivy bridge is due to lower
desirability as they're phased out
* https://cloud.google.com/compute/docs/regions-zones/
2019-02-18 12:55:04 -08:00
e483c81ce9 Improve Prometheus rules and alerts and Grafana dashboards
* Collate upstream rules, alerts, and dashboards and tune for use
in Typhoon
* Previously, a well-chosen (but older) set of rules, alerts, and
dashboards were maintained to reflect metric name changes

9c59f393a5 Add Kubernetes pod name to metrics discovered from service endpoints
* Prometheus queries from some upstreams use joins of node-exporter
and kube-state-metrics metrics by (namespace,pod). Add the Kubernetes
pod name to service endpoint metrics
* Rename the kubernetes_namespace field to namespace
* Honor labels since kube-state-metrics already include a `pod` field
that should not be overridden

244a1a601a Switch CoreDNS to use the forward plugin instead of proxy
* Use the forward plugin to forward to upstream resolvers, instead
of the proxy plugin. The forward plugin is reported to be a faster
alternative since it can re-use open sockets

* Fix minor docs typos and errors
* Allow a transient verison of the six PyPi package, the
docs build system can use the 0.12.0 (0.11.0 broke sync

2019-01-15 21:13:16 -08:00
7eafa59d8f Fix instance shutdown automatic worker deletion on clouds
* Fix a regression caused by lowering the Kubelet TLS client
certificate to system:nodes group (#100) since dropping
cluster-admin dropped the Kubelet's ability to delete nodes.
* On clouds where workers can scale down (manual terraform apply,
AWS spot termination, Azure low priority deletion), worker shutdown
runs the delete-node.service to remove a node to prevent NotReady
nodes from accumulating
* Allow Kubelets to delete cluster nodes via system:nodes group. Kubelets
acting with system:node and kubelet-delete ClusterRoles is still an
improvement over acting as cluster-admin
2019-01-14 23:27:48 -08:00
679079b242 Add AWS ingress_zone_id output with NLB DNS name's Route53 zone id
* DNS zones served by AWS Route53 may use AWS's special alias records
(other DNS providers would use a CNAME) to resolve the ingress NLB.
Alias records require the NLB DNS name's DNS zone id (not the cluster
`dns_zone_id`)

## Latest
## v1.13.5
* Kubernetes [v1.13.5](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1135)
* Resolve in-addr.arpa reverse DNS lookups (PTR) for pod IPv4 addresses ([#415](https://github.com/poseidon/typhoon/pull/415))
* Reverse DNS lookups for service IPv4 addresses unchanged
* Upgrade Calico from v3.5.2 to [v3.6.0](https://docs.projectcalico.org/v3.6/release-notes/) ([#430](https://github.com/poseidon/typhoon/pull/430))
* Change pod IPAM from `host-local` to `calico-ipam`. `pod_cidr` is still divided into `/24` subnets per node, but managed as `ippools` and `ipamblocks`
* Suggest updating [terraform-provider-ct](https://github.com/coreos/terraform-provider-ct) from v0.3.0 to [v0.3.1](https://github.com/coreos/terraform-provider-ct/releases/tag/v0.3.1) ([#434](https://github.com/poseidon/typhoon/pull/434))
* Announce: Fedora Atomic modules will be not be updated beyond Kubernetes v1.13.x ([#437](https://github.com/poseidon/typhoon/pull/437))
* Thank you Project Atomic team and users, please see the deprecation [notice](https://typhoon.psdn.io/announce/#march-27-2019)
#### AWS
* Support `terraform-provider-aws` v2.0+ ([#419](https://github.com/poseidon/typhoon/pull/419))
#### Bare-Metal
* Change the default iPXE kernel and initrd download protocol from HTTP to HTTPS ([#420](https://github.com/poseidon/typhoon/pull/420))
* Require an iPXE-enabled network boot environment with support for TLS downloads. PXE clients must chainload to iPXE firmware compiled with `DOWNLOAD_PROTO_HTTPS` [enabled](https://ipxe.org/crypto). (**action required**)
* Only affects Container Linux and Flatcar Linux install profiles that pull public images (default)
* Add `download_protocol` variable. Recognizing boot firmware TLS support is difficult in some environments, set the protocol to "http" for the old behavior (discouraged)
#### DigitalOcean
* Fix kubelet hostname-override to set node metadata InternalIP correctly ([#424](https://github.com/poseidon/typhoon/issues/424))
* Uniquely, DigitalOcean does not resolve hostnames to instance private IPs. Kubelet auto-detect mechanisms require the internal IP be set directly.
* Regressed in v1.12.3 ([#337](https://github.com/poseidon/typhoon/pull/337)) which aimed to provide friendly hostname-based node names on DigitalOcean
#### Addons
* Update Prometheus from v2.7.1 to [v2.8.0](https://github.com/prometheus/prometheus/releases/tag/v2.8.0)
* Refresh rules based on upstreams ([#426](https://github.com/poseidon/typhoon/pull/426))
* Define NetworkPolicy to allow only traffic from the Grafana addon
* Update Grafana from v6.0.0 to v6.0.2
* Add liveness and readiness probes
* Refresh dashboards and organize to stay below ConfigMap size limit ([#426](https://github.com/poseidon/typhoon/pull/426))
* Remove heapster manifests from addons ([#427](https://github.com/poseidon/typhoon/pull/427))
* Heapster addon powers `kubectl top` (in early Kubernetes, running the addon was expected). Today, there are better monitoring options.
* `kubectl top` reliance on a non-core extension means its not in-scope for minimal Kubernetes
* Look to prior releases if you still wish to apply heapster
## v1.13.4
* Kubernetes [v1.13.4](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1134)
* Update etcd from v3.3.11 to [v3.3.12](https://github.com/etcd-io/etcd/releases/tag/v3.3.12)
* Update Calico from v3.5.0 to [v3.5.2](https://docs.projectcalico.org/v3.5/releases/)
* Assign priorityClassNames to critical cluster and node components ([#406](https://github.com/poseidon/typhoon/pull/406))
* Inform node out-of-resource eviction and scheduler preemption and ordering
* Add CoreDNS readiness probe ([#410](https://github.com/poseidon/typhoon/pull/410))
#### Bare-Metal
* Recommend updating [terraform-provider-matchbox](https://github.com/coreos/terraform-provider-matchbox) plugin from v0.2.2 to [v0.2.3](https://github.com/coreos/terraform-provider-matchbox/releases/tag/v0.2.3) ([#402](https://github.com/poseidon/typhoon/pull/402))
* Improve docs on using Ubiquiti EdgeOS with bare-metal clusters ([#413](https://github.com/poseidon/typhoon/pull/413))
#### Google Cloud
* Support `terraform-provider-google` v2.0+ ([#407](https://github.com/poseidon/typhoon/pull/407))
* Require `terraform-provider-google` v1.19+ (**action required**)
* Set the minimum CPU platform to Intel Haswell ([#405](https://github.com/poseidon/typhoon/pull/405))
* Haswell or better is available in every zone (no price change)
* A few zones still default to Sandy/Ivy Bridge (shifts in April 2019)
#### Addons
* Modernize Prometheus rules and alerts ([#404](https://github.com/poseidon/typhoon/pull/404))
* Drop extraneous metrics ([#397](https://github.com/poseidon/typhoon/pull/397))
* Add `pod` name label to metrics discovered via service endpoints
* Rename `kubernetes_namespace` label to `namespace`
* Modernize Grafana and dashboards, see [docs](https://typhoon.psdn.io/addons/grafana/) ([#403](https://github.com/poseidon/typhoon/pull/403), [#404](https://github.com/poseidon/typhoon/pull/404))
* Upgrade Grafana from v5.4.3 to [v6.0.0](https://github.com/grafana/grafana/releases/tag/v6.0.0)!
* Enable Grafana [Explore](http://docs.grafana.org/guides/whats-new-in-v6-0/#explore) UI as a Viewer (inspect/edit without saving)
* Update nginx-ingress from v0.22.0 to v0.23.0
* Raise nginx-ingress liveness/readiness timeout to 5 seconds
* Remove nginx-ingess default-backend ([#401](https://github.com/poseidon/typhoon/pull/401))
#### Fedora Atomic
* Build Kubelet [system container](https://github.com/poseidon/system-containers) with buildah. The image is an OCI format and slightly larger.
## v1.13.3
* Kubernetes [v1.13.3](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1133)
* Update etcd from v3.3.10 to [v3.3.11](https://github.com/etcd-io/etcd/blob/master/CHANGELOG-3.3.md#v3311-2019-1-11)
* Update CoreDNS from v1.3.0 to [v1.3.1](https://coredns.io/2019/01/13/coredns-1.3.1-release/)
* Switch from the `proxy` plugin to the faster `forward` plugin for upsteam resolvers
* Update Calico from v3.4.0 to [v3.5.0](https://docs.projectcalico.org/v3.5/releases/)
* Update flannel from v0.10.0 to [v0.11.0](https://github.com/coreos/flannel/releases/tag/v0.11.0)
* Reduce pod eviction timeout for deleting pods on unready nodes to 1 minute
* Respond more quickly to node preemption (previously 5 minutes)
* Fix automatic worker deletion on shutdown for cloud platforms
* Lowering Kubelet privileges in [#372](https://github.com/poseidon/typhoon/pull/372) dropped a needed node deletion authorization. Scale-in due to manual terraform apply (any cloud), AWS spot termination, or Azure low priority deletion left old nodes registered, requiring manual deletion (`kubectl delete node name`)
#### AWS
* Add `ingress_zone_id` output with the NLB DNS name's Route53 zone for use in alias records ([#380](https://github.com/poseidon/typhoon/pull/380))
#### Azure
* Fix azure provider warning, `public_ip` `allocation_method` replaces `public_ip_address_allocation`
* Require `terraform-provider-azurerm` v1.21+ (action required)
#### Addons
* Update nginx-ingress from v0.21.0 to v0.22.0
* Update Prometheus from v2.6.0 to v2.7.1
* Update kube-state-metrics from v1.4.0 to v1.5.0
* Fix ClusterRole to collect and export PodDisruptionBudget metrics ([#383](https://github.com/poseidon/typhoon/pull/383))
* Update node-exporter from v0.15.2 to v0.17.0
* Update Grafana from v5.4.2 to v5.4.3
## v1.13.2
* Kubernetes [v1.13.2](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1132)
* Add ServiceAccounts for `kube-apiserver` and `kube-scheduler` ([#370](https://github.com/poseidon/typhoon/pull/370))
* Use lower-privilege TLS client certificates for Kubelets ([#372](https://github.com/poseidon/typhoon/pull/372))

# Announce <img align="right" src="https://storage.googleapis.com/poseidon/typhoon-logo-small.png">
## March 27, 2019
Last April, Typhoon [introduced](#april-26-2018) alpha support for creating Kubernetes clusters with Fedora Atomic on AWS, Google Cloud, DigitalOcean, and bare-metal. Fedora Atomic shared many of Container Linux's aims for a container-optimized operating system, introduced novel ideas, and provided technical diversification for an uncertain future. However, Project Atomic efforts were merged into Fedora CoreOS and future Fedora Atomic releases are [not expected](http://www.projectatomic.io/blog/2018/06/welcome-to-fedora-coreos/). *Typhoon modules for Fedora Atomic will not be updated much beyond Kubernetes v1.13*. They may later be removed.
Typhoon for Fedora Atomic fell short of goals to provide a consistent, practical experience across operating systems and platforms. The modules have remained alpha, despite improvements. Features like coordinated OS updates and boot-time declarative customization were not realized. Inelegance of Cloud-Init/kickstart loomed large. With that brief but obligatory summary, I'd like to change gears and celebrate the many positives.
Fedora Atomic showcased [rpm-ostree](https://github.com/projectatomic/rpm-ostree) as a different approach to Container Linux's AB update scheme. It provided a viable route toward [CRI-O](https://github.com/kubernetes-sigs/cri-o) to replace Docker as the container engine. And Fedora Atomic devised [system containers](http://www.projectatomic.io/blog/2016/09/intro-to-system-containers/) as a way to package and run raw OCI images through runc for host-level containers[^2]. Many of these ideas will live on in Fedora CoreOS, which is exciting!
For Typhoon, Fedora Atomic brought fresh ideas and broader perspectives about different container-optimized base operating systems and related tools. Its sad to let go of so much work, but I think its time. Many of the concepts and technologies that were explored will surface again and Typhoon is better positioned as a result.
Thank you Project Atomic team members for your work! - dghubble
[^2]: Container Linux's own primordial rkt-fly shim dates back to the pre-OCI era. In some ways, rkt drove the OCI standards that made newer ideas, like system containers, appealing.

Starting in v1.10.3, Typhoon AWS and bare-metal `container-linux` modules allow picking between the Red Hat [Container Linux](https://coreos.com/os/docs/latest/) (formerly CoreOS Container Linux) and Kinvolk [Flatcar Linux](https://www.flatcar-linux.org/) operating system. Flatcar Linux serves as a drop-in compatible "friendly fork" of Container Linux. Flatcar Linux publishes the same channels and versions as Container Linux and gets provisioned, managed, and operated in an identical way (e.g. login as user "core").

For newcomers, Typhoon is a free (cost and freedom) Kubernetes distribution providing upstream Kubernetes, declarative configuration via [Terraform](https://www.terraform.io/intro/index.html), and support for AWS, Google Cloud, DigitalOcean, and bare-metal. Typhoon clusters use a [self-hosted](https://github.com/kubernetes-incubator/bootkube) control plane, support [Calico](https://www.projectcalico.org/blog/) and [flannel](https://coreos.com/flannel/docs/latest/) CNI networking, and enable etcd TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/), and network policy.
Typhoon for Fedora Atomic reflects many of the same principles that created Typhoon for Container Linux. Clusters are declared using plain Terraform configs that can be versioned. In lieu of Ignition, instances are declaratively provisioned with Cloud-Init and kickstart (bare-metal only). TLS assets are generated. Hosts run only a kubelet service, other components are scheduled (i.e. self-hosted). The upstream hyperkube is used directly[^1]. And clusters are kept minimal by offering optional addons for [Ingress](https://typhoon.psdn.io/addons/ingress/), [Prometheus](https://typhoon.psdn.io/addons/prometheus/), and [Grafana](https://typhoon.psdn.io/addons/grafana/). Typhoon compliments and enhances Fedora Atomic as a choice of operating system for Kubernetes.
