Dalton Hubble d31f444fcd Update Kubernetes from v1.12.3 to v1.13.0 2018-12-03 20:44:32 -08:00
Dalton Hubble 76d993cdae Add experimental kube-router CNI provider
* Add kube-router for pod networking and NetworkPolicy
as an experiment
* Experiments are not documented or supported in any way,
and may be removed without notice. They have known issues
and aren't enabled without special options.

Dalton Hubble 840b73f9ba Update pod-checkpointer image to query Kubelet secure API
* Updates pod-checkpointer to prefer the Kubelet secure
API (before falling back to the Kubelet read-only API that
is disabled on Typhoon clusters since
https://github.com/poseidon/typhoon/pull/324)
* Previously, pod-checkpointer checkpointed an initial set
of pods during bootstrapping so recovery from power cycling
clusters was unaffected, but logs were noisy

Dalton Hubble 915af3c6cc Fix Calico Felix reporting usage data, require opt-in
* Calico Felix has been reporting anonymous usage data about the
version and cluster size, which violates Typhoon's privacy policy
where analytics should be opt-in only
* Add a variable enable_reporting (default: false) to allow opting
in to reporting usage data to Calico (or future components)

Dalton Hubble ea3fc6d2a7 Update CoreDNS from v1.2.4 to v1.2.6

Dalton Hubble 56e9a82984 Add flannel resource request and mount only /run/flannel 2018-11-11 20:35:21 -08:00
Dalton Hubble e95b856a22 Enable CoreDNS loop and loadbalance plugins
* loop sends an initial query to detect infinite forwarding
loops in configured upstream DNS servers and fast exit with
an error (its a fatal misconfiguration on the network that
will otherwise cause resolvers to consume memory/CPU until
crashing, masking the problem)
* https://github.com/coredns/coredns/tree/master/plugin/loop
* loadbalance randomizes the ordering of A, AAAA, and MX records
in responses to provide round-robin load balancing (as usual,
clients may still cache responses though)
* https://github.com/coredns/coredns/tree/master/plugin/loadbalance

Dalton Hubble 2b3f61d1bb Update Calico from v3.3.0 to v3.3.1
* Structure Calico and flannel manifests
* Rename kube-flannel mentions to just flannel

Dalton Hubble 721c847943 Set kube-apiserver kubelet preferred address types
* Prefer InternalIP and ExternalIP over the node's hostname,
to match upstream behavior and kubeadm
* Previously, hostname-override was used to set node names
to internal IP's to work around some cloud providers not
resolving hostnames for instances (e.g. DO droplets)

Dalton Hubble d55bfd5589 Fix CoreDNS AntiAffinity spec to prefer spreading replicas
* Pods were still being scheduled at random due to a typo
2018-10-17 22:19:57 -07:00
Dalton Hubble 9b6113a058 Update Kubernetes from v1.11.3 to v1.12.1
* Mount an empty dir for the controller-manager to work around
https://github.com/kubernetes/kubernetes/issues/68973
* Update coreos/pod-checkpointer to strip affinity from
checkpointed pod manifests. Kubernetes v1.12.0-rc.1 introduced
a default affinity that appears on checkpointed manifests; but
it prevented scheduling and checkpointed pods should not have an
affinity, they're run directly by the Kubelet on the local node

* Overrides Kubernetes default behavior which started containers
with seccomp=unconfined

Dalton Hubble 55bb4dfba6 Raise CoreDNS replica count to 2 or more
* Run at least two replicas of CoreDNS to better support
rolling updates (previously, kube-dns had a pod nanny)
* On multi-master clusters, set the CoreDNS replica count
to match the number of masters (e.g. a 3-master cluster
previously used replicas:1, now replicas:3)
* Add AntiAffinity preferred rule to favor distributing
CoreDNS pods across controller nodes nodes
2018-10-13 20:31:29 -07:00
Dalton Hubble 43fe78a2cc Raise scheduler/controller-manager replicas in multi-master
* Continue to ensure scheduler and controller-manager run
at least two replicas to support performing kubectl edits
on single-master clusters (no change)
* For multi-master clusters, set scheduler / controller-manager
replica count to the number of masters (e.g. a 3-master cluster
previously used replicas:2, now replicas:3)

Dalton Hubble 6c5a1964aa Change kube-apiserver port from 443 to 6443
* Adjust firewall rules, security groups, cloud load balancers,
and generated kubeconfig's
* Facilitates some future simplifications and cost reductions
* Bare-Metal users who exposed kube-apiserver on a WAN via their
router or load balancer will need to adjust its configuration.
This is uncommon, most apiserver are on LAN and/or behind VPN
so no routing infrastructure is configured with the port number
