* Update Cilium from v1.8.1 to [v1.8.2](https://github.com/cilium/cilium/releases/tag/v1.8.2)
Update from coreos/flannel-cni to poseidon/flannel-cni * Update CNI plugins from v0.6.0 to v0.8.6 to fix several CVEs * Update the base image to alpine:3.12 * Use `flannel-cni` as an init container and remove sleep * https://github.com/poseidon/terraform-render-bootstrap/pull/205 * https://github.com/poseidon/flannel-cni * https://quay.io/repository/poseidon/flannel-cni Background * Switch from github.com/coreos/flannel-cni v0.3.0 which was last published by me in 2017 and is no longer accessible to me to maintain or patch * Port to the poseidon/flannel-cni rewrite, which releases v0.4.0 to continue the prior release numbering
2020-08-02 09:45:39 +02:00
* Update [coreos/flannel-cni](https://github.com/coreos/flannel-cni) to [poseidon/flannel-cni](https://github.com/poseidon/flannel-cni) ([#798](https://github.com/poseidon/typhoon/pull/798))
* Update CNI plugins and fix CVEs with Flannel (non-default)
* Transition to a poseidon maintained container image
Update etcd from v3.4.9 to v3.4.10 * https://github.com/etcd-io/etcd/releases/tag/v3.4.10
2020-07-18 23:08:22 +02:00
Fix flannel support on Fedora CoreOS * Fedora CoreOS now ships systemd-udev's `default.link` while Flannel relies on being able to pick its own MAC address for the `flannel.1` link for tunneled traffic to reach cni0 on the destination side, without being dropped * This change first appeared in FCOS testing-devel 32.20200624.20.1 and is the behavior going forward in FCOS since it was added to align FCOS network naming / configs with the rest of Fedora and address issues related to the default being missing * Flatcar Linux (and Container Linux) has a specific flannel.link configuration builtin, so it was not affected * https://github.com/coreos/fedora-coreos-tracker/issues/574#issuecomment-665487296 Note: Typhoon's recommended and default CNI provider is Calico, unless `networking` is set to flannel directly.

2020-06-26 10:55:49 +02:00
Isolate each DigitalOcean cluster in its own VPC * DigitalOcean introduced Virtual Private Cloud (VPC) support to match other clouds and enhance the prior "private networking" feature. Before, droplet's belonging to different clusters (but residing in the same region) could reach one another (although Typhoon firewall rules prohibit this). Now, droplets in a VPC reside in their own network * https://www.digitalocean.com/docs/networking/vpc/ * Create droplet instances in a VPC per cluster. This matches the design of Typhoon AWS, Azure, and GCP. * Require `terraform-provider-digitalocean` v1.16.0+ (action required) * Output `vpc_id` for use with an attached DigitalOcean loadbalancer

Remove os_image variable on Google Cloud Fedora CoreOS * In v1.18.3, the `os_stream` variable was added to select a Fedora CoreOS image stream (stable, testing, next) on AWS and Google Cloud (which publish official streams) * Remove `os_image` variable deprecated in v1.18.3. Manually uploaded images are no longer needed
2020-06-30 07:57:11 +02:00
### Fedora CoreOS
Allow using Flatcar Linux edge on Azure * Set Kubelet cgroup driver to systemd when Flatcar Linux edge is chosen Note: Typhoon module status assumes use of the stable variant of an OS channel/stream. Its possible to use earlier variants and those are sometimes tested or developed against, but stable is the recommendation

Use strict mode for Container Linux Configs * Enable terraform-provider-ct `strict` mode for parsing Container Linux Configs and snippets * Fix Container Linux Config systemd unit syntax `enable` (old) to `enabled` * Align with Fedora CoreOS which uses strict mode already
2020-06-10 07:38:32 +02:00
### Fedora CoreOS
#### Azure
* Use `strict` Fedora CoreOS Config (FCC) snippet parsing ([#755](https://github.com/poseidon/typhoon/pull/755))
Reduce Calcio MTU on Fedora CoreOS Azure * Change the Calico VXLAN interface for MTU from 1450 to 1410 * VXLAN on Azure should support MTU 1450. However, there is history where performance measures have shown that 1410 is needed to have expected performance. Flatcar Linux has the same MTU 1410 override and note * FCOS 31.20200323.3.2 was known to perform fine with 1450, but now in 31.20200517.3.0 the right value seems to be 1410
2020-06-19 08:47:35 +02:00
* Reduce Calico vxlan interface MTU to maintain performance ([#767](https://github.com/poseidon/typhoon/pull/766))
Use strict mode for Container Linux Configs * Enable terraform-provider-ct `strict` mode for parsing Container Linux Configs and snippets * Fix Container Linux Config systemd unit syntax `enable` (old) to `enabled` * Align with Fedora CoreOS which uses strict mode already
2020-06-10 07:38:32 +02:00
Fix Kubelet starting before hostname set on FCOS AWS * Fedora CoreOS `kubelet.service` can start before the hostname is set. Kubelet reads the hostname to determine the node name to register. If the hostname was read as localhost, Kubelet will continue trying to register as localhost (problem) * This race manifests as a node that appears NotReady, the Kubelet is trying to register as localhost, while the host itself (by then) has an AWS provided hostname. Restarting kubelet.service is a manual fix so Kubelet re-reads the hostname * This race could only be shown on AWS, not on Google Cloud or Azure despite attempts. Bare-metal and DigitalOcean differ and use hostname-override (e.g. afterburn) so they're not affected * Wait for nodes to have a non-localhost hostname in the oneshot that awaits /etc/resolve.conf. Typhoon has no valid cases for a node hostname being localhost (not even single-node clusters) Related Openshift: https://github.com/openshift/machine-config-operator/pull/1813 Close https://github.com/poseidon/typhoon/issues/765

* 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
2020-04-26 01:50:51 +02:00

#### Azure
Fix UDP outbound and clock sync timeouts on Azure workers * Add "lb" outbound rule for worker TCP _and_ UDP traffic * Fix Azure worker nodes clock synchronization being inactive due to timeouts reaching the CoreOS / Flatcar NTP pool * Fix Azure worker nodes not providing outbount UDP connectivity Background: Azure provides VMs outbound connectivity either by having a public IP or via an SNAT masquerade feature bundled with their virtual load balancing abstraction (in contrast with, say, a NAT gateway). Azure worker nodes have only a private IP, but are associated with the cluster load balancer's backend pool and ingress frontend IP. Outbound traffic uses SNAT with this frontend IP. A subtle detail with Azure SNAT seems to be that since both inbound lb_rule's are TCP only, outbound UDP traffic isn't SNAT'd (highlights the reasons Azure shouldn't have conflated inbound load balancing with outbound SNAT concepts). However, adding a separate outbound rule and disabling outbound SNAT on our ingress lb_rule's we can tell Azure to continue load balancing as before, and support outbound SNAT for worker traffic of both the TCP and UDP protocol. Fixes clock synchronization timeouts: ``` systemd-timesyncd[786]: Timed out waiting for reply from 45.79.36.123:123 (3.flatcar.pool.ntp.org) ``` Azure controller nodes have their own public IP, so controllers (and etcd) nodes have not had clock synchronization or outbound UDP issues

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
2020-03-29 01:49:17 +01:00

Change Container Linux etcd-member to fetch with docker:// * Quay has historically generated ACI signatures for images to facilitate rkt's notions of verification (it allowed authors to actually sign images, though `--trust-keys-from-https` is in use since etcd and most authors don't sign images). OCI standardization didn't adopt verification ideas and checking signatures has fallen out of favor. * Fix an issue where Quay no longer seems to be generating ACI signatures for new images (e.g. quay.io/coreos/etcd:v.3.4.4) * Don't be alarmed by rkt `--insecure-options=image`. It refers to disabling image signature checking (i.e. docker pull doesn't check signatures either) * System containers for Kubelet and bootstrap have transitioned to the docker:// transport, so there is precedent and this brings all the system containers on Container Linux controllers into alignment
2020-03-02 17:11:15 +01:00

Set docker log driver to json-file on Fedora CoreOS * Fix the last minor issue for Fedora CoreOS clusters to pass CNCF's Kubernetes conformance tests * Kubelet supports a seldom used feature `kubectl logs --limit-bytes=N` to trim a log stream to a desired length. Kubelet handles this in the CRI driver. The Kubelet docker shim only supports the limit bytes feature when Docker is configured with the default `json-file` logging driver * CNCF conformance tests started requiring limit-bytes be supported, indirectly forcing the log driver choice until either the Kubelet or the conformance tests are fixed * Fedora CoreOS defaults Docker to use `journald` (desired). For now, as a workaround to offer conformant clusters, the log driver can be set back to `json-file`. RHEL CoreOS likely won't have noticed the non-conformance since its using crio runtime * https://github.com/kubernetes/kubernetes/issues/86367 Note: When upstream has a fix, the aim is to drop the docker config override and use the journald default

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

* Add CPU requests for control plane static pods ([#589](https://github.com/poseidon/typhoon/pull/589))
Add small CPU resource requests to static pods * Set small CPU requests on static pods kube-apiserver, kube-controller-manager, and kube-scheduler to align with upstream tooling and for edge cases * Effectively, a practical case for these requests hasn't been observed. However, a small static pod CPU request may offer a slight benefit if a controller became overloaded and the below mechanisms were insufficient Existing safeguards: * Control plane nodes are tainted to isolate them from ordinary workloads. Even dense workloads can only compress CPU resources on worker nodes. * Control plane static pods use the highest priority class, so contention favors control plane pods (over say node-exporter) and CPU is compressible too. See: https://github.com/poseidon/terraform-render-bootstrap/pull/161
2019-11-14 02:13:36 +01:00
* May provide slight edge case benefits and aligns with upstream
Adopt Terraform v0.12 templatefile function * Update terraform-render-bootstrap module to adopt the Terrform v0.12 templatefile function feature to replace the use of terraform-provider-template's `template_dir` * Require Terraform v0.12.6+ which adds `for_each` Background: * `template_dir` was added to `terraform-provider-template` to add support for template directory rendering in CoreOS Tectonic Kubernetes distribution (~2017) * Terraform v0.12 introduced a native `templatefile` function and v0.12.6 introduced native `for_each` support (July 2019) that makes it possible to replace `template_dir` usage

Fix to add all Azure controller nodes to address pool * Add all Azure controllers to the apiserver load balancer backend address pool * Previously, kube-apiserver availability relied on the 0th controller being up. Multi-controller was just providing etcd data redundancy

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) Related: * https://www.terraform.io/docs/providers/google/r/compute_backend_service.html * https://www.terraform.io/docs/configuration/expressions.html#dynamic-blocks

Add ability to load balance TCP/UDP applications on Azure * Add ability to load balance TCP/UDP applications (e.g. NodePort) * Output the load balancer ID as `loadbalancer_id` * Output `worker_security_group_name` and `worker_address_prefix` for extending firewall rules
2019-04-08 03:04:02 +02:00
* Add `enable_aggregation` option for CNCF conformance ([#436](https://github.com/poseidon/typhoon/pull/436))
Add enable_aggregation option (defaults to false) * Add an `enable_aggregation` variable to enable the kube-apiserver aggregation layer for adding extension apiservers to clusters * Aggregation is **disabled** by default. Typhoon recommends you not enable aggregation. Consider whether less invasive ways to achieve your goals are possible and whether those goals are well-founded * Enabling aggregation and extension apiservers increases the attack surface of a cluster and makes extensions a part of the control plane. Admins must scrutinize and trust any extension apiserver used. * Passing a v1.14 CNCF conformance test requires aggregation be enabled. Having an option for aggregation keeps compliance, but retains the stricter security posture on default clusters
2019-04-07 11:29:07 +02:00
* Aggregation is disabled by default to retain our security stance
* Aggregation increases the security surface area. Extensions become part of the control plane and must be scrutinized carefully and trusted. Favor leaving aggregation disabled.

Remove Haswell minimum CPU platform requirement * Google Cloud API implements `min_cpu_platform` to mean "use exactly this CPU" * Fix error creating clusters in newer regions lacking Haswell platform (e.g. europe-west2) (#438) * Reverts #405, added in v1.13.4 * Original goal of ignoring old Ivy/Sandy bridge CPUs in older regions will be achieved shortly anyway. Google Cloud is deprecating those CPUs in April 2019 * https://cloud.google.com/compute/docs/instances/specify-min-cpu-platform#how_selecting_a_minimum_cpu_platform_works
2019-03-28 03:45:10 +01:00
#### Google Cloud
Add Google Cloud worker instances to a target pool * Background: A managed instance group of workers is used in backend services for global load balancing (HTTP/HTTPS Ingress) and output for custom global load balancing use cases * Add worker instances to a target pool load balancing TCP/UDP applications (NodePort or proxied). Output as `worker_target_pool` * Health check for workers with a healthy Ingress controller. Forward rules (regional) to target pools don't support different external and internal ports so choosing nodes with Ingress allows proxying as a workaround * A target pool is a logical grouping only. It doesn't add costs to clusters or worker pools
2019-03-30 23:12:55 +01:00
* Add ability to load balance TCP/UDP applications ([#442](https://github.com/poseidon/typhoon/pull/442))
* Add worker instances to a target pool, output as `worker_target_pool`
Update bare-metal Fedora CoreOS image location * Use Fedora CoreOS production download streams (change) * Use live PXE kernel and initramfs images * https://getfedora.org/coreos/download/ * Update docs example to use public images (cache is still recommended at large scale) and stable stream
2020-01-14 09:49:34 +01:00
* Health check for workers with Ingress controllers. Forward rules don't support differing internal/external ports, but some Ingress controllers support TCP/UDP proxy as a workaround

* Kubernetes [v1.13.5](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1135)
Resolve in-addr.arpa and ip6.arpa zones with CoreDNS kubernetes plugin * Resolve in-addr.arpa and ip6.arpa DNS PTR requests for Kubernetes service IPs and pod IPs * Previously, CoreDNS was configured to resolve in-addr.arpa PTR records for service IPs (but not pod IPs)
2019-03-05 08:00:13 +01:00
* Resolve in-addr.arpa reverse DNS lookups (PTR) for pod IPv4 addresses ([#415](https://github.com/poseidon/typhoon/pull/415))
* Reverse DNS lookups for service IPv4 addresses unchanged
Update Calico from v3.5.2 to v3.6.0 * Add calico-ipam CRDs and RBAC permissions * Switch IPAM from host-local to calico-ipam * `calico-ipam` subnets `ippools` (defaults to pod CIDR) into `ipamblocks` (defaults to /26, but set to /24 in Typhoon) * `host-local` subnets the pod CIDR based on the node PodCIDR field (set via kube-controller-manager as /24's) * Create a custom default IPv4 IPPool to ensure the block size is kept at /24 to allow 110 pods per node (Kubernetes default) * Retaining host-local was slightly preferred, but Calico v3.6 is migrating all usage to calico-ipam. The codepath that skipped calico-ipam for KDD was removed * https://docs.projectcalico.org/v3.6/release-notes/
2019-03-19 05:07:07 +01:00

Remove heapster manifests from addons * Heapster addon powers `kubectl top` * In early Kubernetes, people legitimately used and expected `kubectl top` to work, so the optional addon was provided * Today the standards are different. Many better monitoring tools exist, that are also less coupled to Kubernetes "kubectl top" reliance on a non-core extensions means its not in-scope for minimal Kubernetes clusters. No more exceptionalism * Finally, Heapster isn't that useful anymore. Its manifests have no need for Typhoon-specific modification * Look to prior releases if you still wish to apply heapster

2019-01-17 07:59:46 +01:00
* Fix automatic worker deletion on shutdown for cloud platforms
Fix instance shutdown automatic worker deletion on clouds * Fix a regression caused by lowering the Kubelet TLS client certificate to system:nodes group (#100) since dropping cluster-admin dropped the Kubelet's ability to delete nodes. * On clouds where workers can scale down (manual terraform apply, AWS spot termination, Azure low priority deletion), worker shutdown runs the delete-node.service to remove a node to prevent NotReady nodes from accumulating * Allow Kubelets to delete cluster nodes via system:nodes group. Kubelets acting with system:node and kubelet-delete ClusterRoles is still an improvement over acting as cluster-admin
2019-01-15 08:24:41 +01:00
* Lowering Kubelet privileges in [#372](https://github.com/poseidon/typhoon/pull/372) dropped a needed node deletion authorization. Scale-in due to manual terraform apply (any cloud), AWS spot termination, or Azure low priority deletion left old nodes registered, requiring manual deletion (`kubectl delete node name`)

Recommend switch from ~/.terraformrc to 3rd-party plugin dir * Switch tutorials from using ~/.terraformrc to using the 3rd-party plugin directory so 3rd-party plugins can be pinned * Continue to show using terraform-provider-ct v0.2.2. Updating to a newer version is only safe once all managed clusters are v1.12.2 or higher
2018-11-27 09:08:51 +01:00
* [Recommend](https://typhoon.psdn.io/topics/maintenance/#terraform-plugins-directory) switching from `~/.terraformrc` to the Terraform [third-party plugins](https://www.terraform.io/docs/configuration/providers.html#third-party-plugins) directory `~/.terraform.d/plugins/`.
* Allows pinning `terraform-provider-ct` and `terraform-provider-matchbox` versions
* Improves safety of later plugin version migrations
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)

* Ingress addon users may keep using CNAME records to the `ingress_dns_name` module output (few million RPS)
* Ingress users with heavy traffic (many million RPS) should create a separate NLB(s)
* Worker pools no longer include an extraneous load balancer. Remove worker module's `ingress_dns_name` output
Disable AWS detailed monitoring on worker nodes * Basic monitoring (free) is sufficient for casual console browsing * Detailed monitoring (paid) is not leveraged for CloudWatch anyway * Favor Prometheus for cloud-agnostic metrics, aggregation, and alerting

Switch GCP network lb to global TCP proxy lb * Allow multi-controller clusters on Google Cloud * GCP regional network load balancers have a long open bug in which requests originating from a backend instance are routed to the instance itself, regardless of whether the health check passes or not. As a result, only the 0th controller node registers. We've recommended just using single master GCP clusters for a while * https://issuetracker.google.com/issues/67366622 * Workaround issue by switching to a GCP TCP Proxy load balancer. TCP proxy lb routes traffic to a backend service (global) of instance group backends. In our case, spread controllers across 3 zones (all regions have 3+ zones) and organize them in 3 zonal unmanaged instance groups that serve as backends. Allows multi-controller cluster creation * GCP network load balancers only allowed legacy HTTP health checks so kubelet 10255 was checked as an approximation of controller health. Replace with TCP apiserver health checks to detect unhealth or unresponsive apiservers. * Drawbacks: GCP provision time increases, tailed logs now timeout (similar tradeoff in AWS), controllers only span 3 zones instead of the exact number in the region * Workaround in Typhoon has been known and posted for 5 months, but there still appears to be no better alternative. Its probably time to support multi-master and accept the downsides
2018-04-15 09:50:43 +02:00
#### Google Cloud

Fix bare-metal multiple apply/ssh on Terraform v0.11.4+ * Terraform v0.11.4 introduced changes to remote-exec that mean Typhoon bare-metal clusters require multiple runs of terraform apply to ssh and bootstrap. * Bare-metal installs PXE boot a live instance to install to disk and then reboot from disk as controllers/workers. Terraform remote-exec has no way to "know" to wait until the reboot has occurred to kickoff Kubernetes bootstrap. Previously Typhoon created a "debug" user during this install phase to allow an admin to SSH, but remote-exec would hang, trying to connect as user "core". Terraform v0.11.4 changes this behavior so remote-exec fails and a user must re-run terraform apply until succeeding. * A new way to "trick" remote-exec into waiting for the reboot into the disk install is to run SSH on a non-standard port during the disk install. This retains the ability for an admin to SSH during install (most distros don't have this) and fixes the issue so only a single run of terraform apply is needed. * https://github.com/hashicorp/terraform/pull/17359#issuecomment-376415464

Create separate bare-metal container-linux-install profiles * Create separate container-linux-install profiles (and cached-container-linux-install) for each node in a cluster * Fix contention bug on bare-metal during `terraform apply`. With only a global install profile, terraform would create (or retain) the profile for each cluster and try to delete it for each cluster being deleted. As a result, in some cases apply had to be run multiple times before terraform's repr of constraints was satisfied (profile deleted and recreated) * Allow Container Linux install properties to vary between clusters, such as using a different Container Linux channel or version for different clusters
2018-01-14 21:36:40 +01:00

Relax digitalocean provider version constraints * Relax fixed 0.1.2 version constraint to "~> 0.1.2", which allows 0.1.3, 0.1.4, etc, but would not allow 0.2.0
2018-01-16 05:57:55 +01:00
