- @[email protected]
- @[email protected]
Deprecate publishing to the Terraform Module Registry
- Typhoon docs have always shown using Git-based module sources, not the Terraform Module Registry
- Module usage should be source = "git::https://github.com/poseidon/typhoon/... not source = poseidon/kubernetes/...
- Terraform's Module Registry requires subtree mirroring typhoon to special terraform-platform-kubernetes repos, only supports release versions (no commit SHAs or forks), only ever contained Flatcar Linux modules (not Fedora CoreOS) for historical reasons
- Note, this does not affect Terraform Providers like poseidon/matchbox or poseidon/ct, the registry works well for providers

variant: flatcar
version: 1.0.0
...

Fedora CoreOS

Remove ineffective /etc/fedora-coreos/iptables-legacy.stamp (#1201)
- Typhoon already uses iptables v1.8.7 (nf_tables) since FCOS 36
- Staying on legacy iptables required a file in /etc/coreos instead

AWS

Refresh instances in autoscaling group when launch configuration changes (#1208) (docs, important)
- Worker launch configuration changes start an autoscaling group instance refresh to replace instances
- Instance refresh creates surge instances, waits for a warm-up period, then deletes old instances
- Changing worker_type, disk_*, worker_price, worker_target_groups, or Butane worker_snippets on existing worker nodes will replace instances
- New AMIs or changing os_stream will be ignored, to allow Fedora CoreOS or Flatcar Linux to keep themselves updated
- Previously, new launch configurations were made in the same way, but not applied to instances unless manually replaced
Rename worker autoscaling group ${cluster_name}-worker (#1202)
- Rename launch configuration ${cluster_name}-worker instead of a random id

Google

Roll instance template changes to worker managed instance groups (#1207) (docs, important)
- Worker instance template changes roll out by gradually replacing instances
- Automatic rollouts create surge instances, wait for health checks, then delete old instances (0 unavailable instances)
- Changing worker_type, disk_size, worker_preemptible, or Butane worker_snippets on existing worker nodes will replace instances
- New compute images or changing os_stream will be ignored, to allow Fedora CoreOS or Flatcar Linux to keep themselves updated
- Previously, new instance templates were made in the same way, but not applied to instances unless manually replaced
Add health checks to worker managed instance groups (i.e. "autohealing") (#1207)
- Use health checks to probe kube-proxy every 30s
- Replace worker nodes that fail the health check 6 times (3min)
Name kube-apiserver and worker health checks consistently (#1207)
- Use name ${cluster_name}-apiserver-health and ${cluster_name}-worker-health
Rename managed instance group from ${cluster_name}-worker-group to ${cluster_name}-worker (#1207)
Fix bug provisioning clusters with multiple controller nodes (#1195)
