147c21a4bd Allow Calico networking on Azure and DigitalOcean
* Introduce "calico" as a `networking` option on Azure and DigitalOcean
using Calico's new VXLAN support (similar to flannel). Flannel remains
the default on these platforms for now.
* Historically, DigitalOcean and Azure only allowed Flannel as the
CNI provider, since those platforms don't support IPIP traffic that
was previously required for Calico.
* Looking forward, its desireable for Calico to become the default
across Typhoon clusters, since it provides NetworkPolicy and a
consistent experience
* No changes to AWS, GCP, or bare-metal where Calico remains the
default CNI provider. On these platforms, IPIP mode will always
be used, since its available and more performant than vxlan

37ce722f9c Fix race condition in DigitalOcean cluster create
* DigitalOcean clusters must secure copy a kubeconfig to
worker nodes, but Terraform could decide to try copying
before firewall rules have been added to allow SSH access.

* Change flannel port from the kernel default 8472 to the
IANA assigned VXLAN port 4789
* Update firewall rules or security groups for VXLAN
* Why now? Calico now offers its own VXLAN backend so
standardizing on the IANA port will simplify config

* kube-state-metrics v1.6.0-rc.0 fires KubeDeploymentReplicasMismatch
alerts where its own Deployment doesn't have replicas available,
(kube_deployment_status_replicas_available) even though all replicas
are available according to kubectl inspection
* This problem was present even with the CSR ClusterRole fix

8da17fb7a2 Fix "google_compute_target_pool.workers: Cannot determine region"
If no region is set at the Google provider level, Terraform fails to
create the google_compute_target_pool.workers resource and complains
with "Cannot determine region: set in this resource, or set provider-level 'region' or 'zone'."

This commit fixes the issue by explicitly setting the region for the
google_compute_target_pool.workers resource.

c1fe41d34a Add ability to load balance TCP/UDP applications on Azure
* Add ability to load balance TCP/UDP applications (e.g. NodePort)
* Output the load balancer ID as `loadbalancer_id`
* Output `worker_security_group_name` and `worker_address_prefix`
for extending firewall rules
2019-04-07 22:59:46 -07:00
be29f52039 Add enable_aggregation option (defaults to false)
* Add an `enable_aggregation` variable to enable the kube-apiserver
aggregation layer for adding extension apiservers to clusters
* Aggregation is **disabled** by default. Typhoon recommends you not
enable aggregation. Consider whether less invasive ways to achieve your
goals are possible and whether those goals are well-founded
* Enabling aggregation and extension apiservers increases the attack
surface of a cluster and makes extensions a part of the control plane.
Admins must scrutinize and trust any extension apiserver used.
* Passing a v1.14 CNCF conformance test requires aggregation be enabled.
Having an option for aggregation keeps compliance, but retains the
stricter security posture on default clusters

60265f9b58 Add ability to load balance TCP applications on AWS
* Add ability to load balance TCP applications (e.g. NodePort)
* Output the network load balancer ARN as `nlb_id`
* Accept a `worker_target_groups` (ARN) list to which worker
instances should be added
* AWS NLBs and target groups don't support UDP
2019-04-01 21:22:20 -07:00
aaa8e0261a Add Google Cloud worker instances to a target pool
* Background: A managed instance group of workers is used in backend
services for global load balancing (HTTP/HTTPS Ingress) and output
for custom global load balancing use cases
* Add worker instances to a target pool load balancing TCP/UDP
applications (NodePort or proxied). Output as `worker_target_pool`
* Health check for workers with a healthy Ingress controller. Forward
rules (regional) to target pools don't support different external and
internal ports so choosing nodes with Ingress allows proxying as a
workaround
* A target pool is a logical grouping only. It doesn't add costs to
clusters or worker pools

"use exactly this CPU"
* Fix error creating clusters in newer regions lacking Haswell
platform (e.g. europe-west2) (#438)

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

2019-03-19 22:49:56 -07:00
aa630003a4 Refresh Prometheus rules and Grafana dashboards

* Organize dashboards and stay below the ConfigMap size
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

* Reverts the "pretty" node names on DigitalOcean (worker-2 vs IP)
* Closes #424 (full details)

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)

* Rename `worker` pool module `count` variable to `worker_count` ([#485](https://github.com/poseidon/typhoon/pull/485)) (action required)
* `count` will become a reserved variable name in Terraform v0.12
#### Bare-Metal
* Recommend updating `terraform-provider-matchbox` plugin from v0.2.3 to [v0.3.0](https://github.com/poseidon/terraform-provider-matchbox/releases/tag/v0.3.0) ([#487](https://github.com/poseidon/typhoon/pull/487))
#### Google Cloud
* Rename `worker` pool module `count` variable to `worker_count` ([#485](https://github.com/poseidon/typhoon/pull/485)) (action required)
* `count` will become a reserved variable name in Terraform v0.12
#### Addons
* Update Prometheus from v2.9.2 to v2.10.0
* Update Grafana from v6.1.6 to v6.2.1
## v1.14.2
* Kubernetes [v1.14.2](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.14.md#v1142)
* Update etcd from v3.3.12 to [v3.3.13](https://github.com/etcd-io/etcd/releases/tag/v3.3.13)
* Upgrade Calico from v3.6.1 to [v3.7.2](https://docs.projectcalico.org/v3.7/release-notes/)
* Change flannel VXLAN port from 8472 (kernel default) to 4789 (IANA VXLAN)
#### AWS
* Only set internal VXLAN rules when `networking` is "flannel" (default: calico)
#### Azure
* Allow choosing Calico as the network provider (experimental) ([#472](https://github.com/poseidon/typhoon/pull/472))
* Add a `networking` variable accepting "flannel" (default) or "calico"
* Use VXLAN encapsulation since Azure doesn't support IPIP
#### DigitalOcean
* Allow choosing Calico as the network provider (experimental) ([#472](https://github.com/poseidon/typhoon/pull/472))
* Add a `networking` variable accepting "flannel" (default) or "calico"
* Use VXLAN encapsulation since DigitalOcean doesn't support IPIP
* Add explicit ordering between firewall rule creation and secure copying Kubelet credentials ([#469](https://github.com/poseidon/typhoon/pull/469))
* Fix race scenario if copies to nodes were before rule creation, blocking cluster creation
#### Addons
* Update Prometheus from v2.8.1 to v2.9.2
* Update kube-state-metrics from v1.5.0 to v1.6.0
* Update node-exporter from v0.17.0 to v0.18.0
* Update Grafana from v6.1.3 to v6.1.6
* Reduce nginx-ingress Role RBAC permissions ([#458](https://github.com/poseidon/typhoon/pull/458))
## v1.14.1
* Kubernetes [v1.14.1](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.14.md#v1141)
#### Addons
* Update Grafana from v6.1.1 to v6.1.3
* Update nginx-ingress from v0.23.0 to v0.24.1
## v1.14.0
* Kubernetes [v1.14.0](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.14.md#v1140)
* Update Calico from v3.6.0 to v3.6.1
* Add `enable_aggregation` option for CNCF conformance ([#436](https://github.com/poseidon/typhoon/pull/436))
* Aggregation is disabled by default to retain our security stance
* Aggregation increases the security surface area. Extensions become part of the control plane and must be scrutinized carefully and trusted. Favor leaving aggregation disabled.
#### AWS
* Add ability to load balance TCP applications ([#443](https://github.com/poseidon/typhoon/pull/443))
* Output the network load balancer ARN as `nlb_id`
* Accept a `worker_target_groups` (ARN) list to which worker instances should be added
#### Azure
* Add ability to load balance TCP/UDP applications ([#447](https://github.com/poseidon/typhoon/pull/447))
* Output the load balancer ID as `loadbalancer_id`
* Output `worker_security_group_name` and `worker_address_prefix` for extending firewall rules ([#447](https://github.com/poseidon/typhoon/pull/447))
#### DigitalOcean
* Harden internal (node-to-node) firewall rules to align with other platforms ([#444](https://github.com/poseidon/typhoon/pull/444))
* Add ability to load balance TCP applications ([#444](https://github.com/poseidon/typhoon/pull/444))
* Output `controller_tag` and `worker_tag` for extending firewall rules ([#444](https://github.com/poseidon/typhoon/pull/444))
#### Google Cloud
* Add ability to load balance TCP/UDP applications ([#442](https://github.com/poseidon/typhoon/pull/442))
* Add worker instances to a target pool, output as `worker_target_pool`
* Health check for workers with Ingress controllers. Forward rules don't support differing internal/external ports, but some Ingress controllers support TCP/UDP proxy as a workaround
* Remove Haswell minimum CPU platform requirement ([#439](https://github.com/poseidon/typhoon/pull/439))
* Google Cloud API implements `min_cpu_platform` to mean "use exactly this CPU". Revert [#405](https://github.com/poseidon/typhoon/pull/405) added in v1.13.4.
* Fix error creating clusters in new regions without Haswell (e.g. europe-west2) ([#438](https://github.com/poseidon/typhoon/issues/438))
#### Addons
* Update Prometheus from v2.8.0 to v2.8.1
* Update Grafana from v6.0.2 to [v6.1.1](http://docs.grafana.org/guides/whats-new-in-v6-1/)
* Add dashboard for pods in a workload (deployment/daemonset/statefulset) ([#446](https://github.com/poseidon/typhoon/pull/446))
* Add dashboard for workloads by namespace
## 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`
* Recommend updating [terraform-provider-ct](https://github.com/poseidon/terraform-provider-ct) from v0.3.0 to [v0.3.1](https://github.com/poseidon/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

# 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

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").

On PXE boot, machines will install Fedora Atomic via kickstart, reboot into the disk install, and provision themselves as Kubernetes controllers or workers via cloud-init.
Controllers are provisioned to run `etcd` and `kubelet` [system containers](http://www.projectatomic.io/blog/2016/09/intro-to-system-containers/). Workers run just a `kubelet` system container. A one-time [bootkube](https://github.com/kubernetes-incubator/bootkube) bootstrap schedules the `apiserver`, `scheduler`, `controller-manager`, and `coredns` on controllers and schedules `kube-proxy` and `calico` (or `flannel`) on every node.
