Michael Schubert d10620fb58 Add support for Flatcar Linux bare-metal cached_install 
* Support bare-metal cached_install=true mode with Flatcar Linux
where assets are fetched from the Matchbox assets cache instead
of from the upstream Flatcar download server
* Skipped in original Flatcar support to keep it simple

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

 2018-10-13 22:40:58 -07:00
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 db36036c81 Require terraform-provider-digitalocean plugin ~> 1.0 
* Require a terraform-provider-digitalocean plugin version of
1.0 or higher within the same major version (e.g. allow 1.1 but
not 2.0)
* Change requirement from ~> 0.1.2 (which allowed up to but not
including 1.0 release)

Dalton Hubble dc03f7a4a9 Update nginx-ingress from 0.17.1 to 0.19.0 
* If using --enable-ssl-passthrough or exposing TCP/UDP services,
be aware of https://github.com/kubernetes/ingress-nginx/pull/3038
* Workarounds until the fix merges are to stay on 0.17.1, use the
suggested development image, or revert to securityContext
`runAsNonRoot: false` for a while (less secure)

Dalton Hubble e58b424882 Fix firewall to allow etcd client traffic between controllers 
* Broaden internal-etcd firewall rule to allow etcd client
traffic (2379) from other controller nodes
* Previously, kube-apiservers were only able to connect to their
node's local etcd peer. While master node outages were tolerated,
reaching a healthy peer took longer than neccessary in some cases
* Reduce time needed to bootstrap a cluster
 2018-08-21 23:51:40 -07:00
Dalton Hubble ea365b551a Fix docs mentions of ELBs to NLBs 
* Typhoon AWS clusters use an NLB rather than an ELB,
since v1.10.5
* Add a few missing links in CHANGES
 2018-08-21 21:40:06 -07:00
Dalton Hubble bbf2c13eef Remove AWS security rule allowing ICMP packets to nodes 
* Deny ICMP packets for consistency across Typhoon clusters on
various clouds and because there isn't much need to allow them
 2018-08-21 21:16:16 -07:00
Dalton Hubble da5d2c5321 Remove GCP firewall rule allowing Nginx Ingress health 
* Nginx Ingress addon no longer uses hostNework so Prometheus may
scrape port 10254 via the CNI network, rather than via the host
address
 2018-08-21 21:06:03 -07:00
Dalton Hubble bec5250e73 Remove unofficial bare-metal *_networkds variables 
* Remove controller_networkds and worker_networkds variables. These
variables were always listed as experimental, unsupported, and excluded
from documentation in anticipation of Container Linux Config snippets
* Use Container Linux Config snippets on bare-metal instead. They
provide safer, more powerful, and more elegant host customization

Dalton Hubble edc250d62a Fix Kublet version for Fedora Atomic modules 
* Release v1.11.1 erroneously left Fedora Atomic clusters using
the v1.11.0 Kubelet. The rest of the control plane ran v1.11.1
as expected
* Update Kubelet from v1.11.0 to v1.11.1 so Fedora Atomic matches
Container Linux
* Container Linux modules were not affected
