# Typhoon
Notable changes between versions.
digital-ocean: Run etcd cluster on-host, across controllers * Run etcd peers with TLS across controller nodes * Deprecate self-hosted-etcd on the Digital Ocean platform * Distribute etcd TLS certificates as part of initial provisioning * Check the status of etcd by running `systemctl status etcd-member`
2017-10-04 09:07:48 +02:00
## Latest
addons: Add better alerting rules to Prometheus manifests * Adapt the coreos/prometheus-operator alerting rules for Typhoon, https://github.com/coreos/prometheus-operator/tree/master/contrib/kube-prometheus/manifests * Add controller manager and scheduler shim services to let prometheus discover them via service endpoints * Fix several alert rules to use service endpoint discovery * A few rules still don't do much, but they default to green
2017-11-08 10:35:56 +01:00
## v1.8.3
Update Kubernetes from v1.8.2 to v1.8.3

2017-11-07 06:19:11 +01:00
Change worker managed instance group to span zones in region * Change Google Cloud module to require the `region` variable * Workers are created in random zones within the given region * Tolerate Google Cloud zone failures or capacity issues * If workers are preempted (if enabled), replacement instances can be drawn from any zone in the region, which should avoid scheduling issues that were possible before if a single zone aggressively preempts instances (presumably due to Google Cloud capacity)
2017-11-04 18:57:12 +01:00
#### Google Cloud
Remove controller_preemptible option on Google Cloud * Controller preemption is not safe or covered in documentation. Delete the option, the variable is a holdover from old experiments * Note, worker_preemeptible is still a great feature that's supported
2017-11-04 19:48:50 +01:00
* Add required variable `region` (e.g. "us-central1")
Run etcd cluster on-host, across controllers on Google Cloud * Change controllers from a managed group to individual instances * Create discrete DNS records to each controller's private IP for etcd * Change etcd to run on-host, across controllers (etcd-member.service) * Reduce time to bootstrap a cluster * Deprecate self-hosted-etcd on the Google Cloud platform
2017-11-05 20:01:50 +01:00

Change worker managed instance group to span zones in region * Change Google Cloud module to require the `region` variable * Workers are created in random zones within the given region * Tolerate Google Cloud zone failures or capacity issues * If workers are preempted (if enabled), replacement instances can be drawn from any zone in the region, which should avoid scheduling issues that were possible before if a single zone aggressively preempts instances (presumably due to Google Cloud capacity)
