Dalton Hubble c7ff1a2e01 Announce a preview with Fedora CoreOS preview 2019-07-18 09:13:40 -07:00
Dalton Hubble 5fdeb9bc78 Adjust Fedora CoreOS image locations
* Use the xz compressed images published by Fedora testing,
instead of gzippped tarballs. This is possible because the
initramfs now supports xz and coreos-installer 0.8 was added
* Separate bios and uefi raw images are no longer needed

Dalton Hubble 155bffa773 Add docs for Fedora CoreOS AWS and bare-metal 2019-07-18 00:55:22 -07:00
Dalton Hubble ce45e123fe Port Typhoon Fedora CoreOS support to AWS
* Use the newly minted "Fedora CoreOS Preview" AMI
* Remove iscsi, kubelet.path activation, and kubeconfig
distribution
* As usual, bare-metal efforts make cloud provider ports
much easier
2019-07-18 00:55:22 -07:00
Dalton Hubble 72c94f1c6a Add Kubelet System Container and bootkube bootstrap
* First semi-working cluster using 30.307-metal-bios
* Enable CPU, Memory, and BlockIO accounting
* Mount /var/lib/kubelet with `rshare` so mounted tmpfs Secrets
(e.g. serviceaccount's) are visible within appropriate containers
* SELinux relabel /etc/kubernetes so install-cni init containers
can write the CNI config to the host /etc/kubernetes/net.d
* SELinux relabel /var/lib/kubelet so ConfigMaps can be read
by containers
* SELinux relabel /opt/cni/bin so install-cni containers can
write CNI binaries to the host
* Set net.ipv4_conf.all.rp_filter to 1 (not 2, loose mode) to
satisfy Calico requirement
* Enable the QoS cgroup hierarchy for pod workloads (kubepods,
burstable, besteffort). Mount /sys/fs/cgroup and
/sys/fs/cgroup/systemd into the Kubelet. Its still rather racy
whether Kubelet will fail on ContainerManager Delegation

Dalton Hubble aab14c5573 Run etcd-member.service across controllers
* Running the etcd container with NOTIFY_SOCKET mounted
(to use systemd Type=notify) causes podman to hang so
for now just use exec

Dalton Hubble eb92f67125 Start prototype of Fedora CoreOS on bare-metal
* Use terraform-provider-ct v0.4.0 with Fedora CoreOS Config
support (not yet released)
2019-07-18 00:55:22 -07:00
Dalton Hubble dfa6bcfecf Relax terraform-provider-ct version constraint
* Allow updating terraform-provider-ct to any release
beyond v0.3.2, but below v1.0. This relaxes the prior
constraint that allowed only v0.3.y provider versions

Dalton Hubble 69d064bfdf Run kube-apiserver with lower privilege user (nobody)
* Run kube-apiserver as a non-root user (nobody). User
no longer needs to bind low number ports.
* On most platforms, the kube-apiserver load balancer listens
on 6443 and fronts controllers with kube-apiserver pods using
port 6443. Google Cloud TCP proxy load balancers cannot listen
on 6443. However, GCP's load balancer can be made to listen on
443, while kube-apiserver uses 6443 across all platforms.

Dalton Hubble 7a69bae75e Raise GCP network deletion timeout from 4m to 6m
* Fix a GCP errata item https://github.com/poseidon/typhoon/wiki/Errata
* Removal of a Google Cloud cluster often required 2 runs of
`terraform apply` because network resource deletes timeout
after 4m. Raise the network deletion timeout to 6m to
ensure apply only needs to be run once to remove a cluster
2019-07-06 13:15:33 -07:00
Dalton Hubble 3fcb04f68c Improve apiserver backend service zone spanning
* google_compute_backend_services use nested blocks to define
backends (instance groups heterogeneous controllers)
* Use Terraform v0.12.x dynamic blocks so the apiserver backend
service can refer to (up to zone-many) controller instance groups
* Previously, with Terraform v0.11.x, the apiserver backend service
had to list a fixed set of backends to span controller nodes across
zones in multi-controller setups. 3 backends were used because each
GCP region offered at least 3 zones. Single-controller clusters had
the cosmetic ugliness of unused instance groups
* Allow controllers to span more than 3 zones if avilable in a
region (e.g. currently only us-central1, with 4 zones)

(some clouds add it automatically)

* Leave docs tutorials the same, they can reflect master

Dalton Hubble 28506df9c7 Avoid unneeded rotations of Regular priority virtual machine scale sets
* Azure only allows `eviction_policy` to be set for Low priority VMs.
Supporting Low priority VMs meant when Regular VMs were used, each

* Terraform v0.12 nullable variables fix the issue and plan does not
produce a diff
