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

* https://github.com/kubernetes/kubernetes/pull/68173

Dalton Hubble 5eb4078d68 Add docker/default seccomp to control plane and addons
* Annotate pods, deployments, and daemonsets to start containers
with the Docker runtime's default seccomp profile
* 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
