## v1.18.3
* Kubernetes [v1.18.3](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.18.md#v1183)
Enable Kubelet TLS bootstrap and NodeRestriction * Enable bootstrap token authentication on kube-apiserver * Generate the bootstrap.kubernetes.io/token Secret that may be used as a bootstrap token * Generate a bootstrap kubeconfig (with a bootstrap token) to be securely distributed to nodes. Each Kubelet will use the bootstrap kubeconfig to authenticate to kube-apiserver as `system:bootstrappers` and send a node-unique CSR for kube-controller-manager to automatically approve to issue a Kubelet certificate and kubeconfig (expires in 72 hours) * Add ClusterRoleBinding for bootstrap token subjects (`system:bootstrappers`) to have the `system:node-bootstrapper` ClusterRole * Add ClusterRoleBinding for bootstrap token subjects (`system:bootstrappers`) to have the csr nodeclient ClusterRole * Add ClusterRoleBinding for bootstrap token subjects (`system:bootstrappers`) to have the csr selfnodeclient ClusterRole * Enable NodeRestriction admission controller to limit the scope of Node or Pod objects a Kubelet can modify to those of the node itself * Ability for a Kubelet to delete its Node object is retained as preemptible nodes or those in auto-scaling instance groups need to be able to remove themselves on shutdown. This need continues to have precedence over any risk of a node deleting itself maliciously Security notes: 1. Issued Kubelet certificates authenticate as user `system:node:NAME` and group `system:nodes` and are limited in their authorization to perform API operations by Node authorization and NodeRestriction admission. Previously, a Kubelet's authorization was broader. This is the primary security motivation. 2. The bootstrap kubeconfig credential has the same sensitivity as the previous generated TLS client-certificate kubeconfig. It must be distributed securely to nodes. Its compromise still allows an attacker to obtain a Kubelet kubeconfig 3. Bootstrapping Kubelet kubeconfig's with a limited lifetime offers a slight security improvement. * An attacker who obtains the kubeconfig can likely obtain the bootstrap kubeconfig as well, to obtain the ability to renew their access * A compromised bootstrap kubeconfig could plausibly be handled by replacing the bootstrap token Secret, distributing the token to new nodes, and expiration. Whereas a compromised TLS-client certificate kubeconfig can't be revoked (no CRL). However, replacing a bootstrap token can be impractical in real cluster environments, so the limited lifetime is mostly a theoretical benefit. * Cluster CSR objects are visible via kubectl which is nice 4. Bootstrapping node-unique Kubelet kubeconfigs means Kubelet clients have more identity information, which can improve the utility of audits and future features Rel: https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet-tls-bootstrapping/ Rel: https://github.com/poseidon/terraform-render-bootstrap/pull/185

* Fix Fedora CoreOS AMI to filter for stable images ([#685](https://github.com/poseidon/typhoon/pull/685))
* Latest Fedora CoreOS `testing` or `bodhi-update` images could be chosen depending on the region
#### Bare-Metal
* Update Fedora CoreOS default `os_stream` from testing to stable
Allow bootstrap re-apply for Fedora CoreOS GCP * Problem: Fedora CoreOS images are manually uploaded to GCP. When a cluster is created with a stale image, Zincati immediately checks for the latest stable image, fetches, and reboots. In practice, this can unfortunately occur exactly during the initial cluster bootstrap phase. * Recommended: Upload the latest Fedora CoreOS image regularly * Mitigation: Allow a failed bootstrap.service run (which won't touch the done ConditionalPathExists) to be re-run by running `terraforma apply` again. Add a known issue to CHANGES * Update docs to show the current Fedora CoreOS stable version to reduce likelihood users see this issue Longer term ideas: * Ideal: Fedora CoreOS publishes a stable channel. Instances will always boot with the latest image in a channel. The problem disappears since it works the same way AWS does * Timer: Consider some timer-based approach to have zincati delay any system reboots for the first ~30 min of a machine's life. Possibly just configured on the controller node https://github.com/coreos/zincati/pull/251 * External coordination: For Container Linux, locksmith filled a similar role and was disabled to allow CLUO to coordinate reboots. By running atop Kubernetes, it was not possible for the reboot to occur before cluster bootstrap * Rely on https://github.com/coreos/zincati/issues/115 to delay the reboot since bootstrap involves an SSH session * Use path-based activation of zincati on controllers and set that path at the end of the bootstrap process Rel: https://github.com/coreos/fedora-coreos-tracker/issues/239

Inline Container Linux kubelet.service, deprecate kubelet-wrapper * Change kubelet.service on Container Linux nodes to ExecStart Kubelet inline to replace the use of the host OS kubelet-wrapper script * Express rkt run flags and volume mounts in a clear, uniform way to make the Kubelet service easier to audit, manage, and understand * Eliminate reliance on a Container Linux kubelet-wrapper script * Typhoon for Fedora CoreOS developed a kubelet.service that similarly uses an inline ExecStart (except with podman instead of rkt) and a more minimal set of volume mounts. Adopt the volume improvements: * Change Kubelet /etc/kubernetes volume to read-only * Change Kubelet /etc/resolv.conf volume to read-only * Remove unneeded /var/lib/cni volume mount Background: * kubelet-wrapper was added in CoreOS around the time of Kubernetes v1.0 to simplify running a CoreOS-built hyperkube ACI image via rkt-fly. The script defaults are no longer ideal (e.g. rkt's notion of trust dates back to quay.io ACI image serving and signing, which informed the OCI standard images we use today, though they still lack rkt's signing ideas). * Shipping kubelet-wrapper was regretted at CoreOS, but remains in the distro for compatibility. The script is not updated to track hyperkube changes, but it is stable and kubelet.env overrides bridge most gaps * Typhoon Container Linux nodes have used kubelet-wrapper to rkt/rkt-fly run the Kubelet via the official k8s.gcr.io hyperkube image using overrides (new image registry, new image format, restart handling, new mounts, new entrypoint in v1.17). * Observation: Most of what it takes to run a Kubelet container is defined in Typhoon, not in kubelet-wrapper. The wrapper's value is now undermined by having to workaround its dated defaults. Typhoon may be better served defining Kubelet.service explicitly * Typhoon for Fedora CoreOS developed a kubelet.service without the use of a host OS kubelet-wrapper which is both clearer and eliminated some volume mounts

* 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.

* 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

#### AWS
* Switch `kube-apiserver` port from 443 to 6443 ([#248](https://github.com/poseidon/typhoon/pull/248))
* Combine apiserver and ingress NLBs ([#249](https://github.com/poseidon/typhoon/pull/249))
* Reduce cost by ~$18/month per cluster. Typhoon AWS clusters now use one network load balancer.
* Ingress addon users may keep using CNAME records to the `ingress_dns_name` module output (few million RPS)

* Users who exposed kube-apiserver on a WAN via their router/load-balancer will need to adjust its configuration (e.g. DNAT 6443). Most apiservers are on a LAN (internal, VPN-only, etc) so if you didn't specially configure network gear for 443, no change is needed. (possible action required)
* Fix possible deadlock when provisioning clusters larger than 10 nodes ([#244](https://github.com/poseidon/typhoon/pull/244))
2018-06-15 07:28:11 +02:00
