StatefulSet — Inrun

Read what is particular to a StatefulSet: its current and update revisions, and the partition of a staged rolling update. Replica counts, rollout completion and pods have their own functions.

Reference

Function	Description
`statefulSetCurrentRevision`	Returns `status.currentRevision` — the pod template hash of currently running pods, or `""` before the first rollout.
`statefulSetPartition`	Returns the partition of a StatefulSet’s rolling update (spec.updateStrategy.rollingUpdate.partition): pods with an ordinal at or above it are updated, the rest keep the old revision.
`statefulSetUpdateRevision`	Returns `status.updateRevision` — the hash of the pending update; equal to `currentRevision` when the rollout is complete.

Functions

statefulSetCurrentRevision

statefulSetCurrentRevision returns status.currentRevision — the pod template hash of currently running pods, or "" before the first rollout.

{{ statefulSetCurrentRevision .statefulset }}  → "db-6d8f4b9c5"

statefulSetPartition

statefulSetPartition returns the partition of a StatefulSet’s rolling update (spec.updateStrategy.rollingUpdate.partition): pods with an ordinal at or above it are updated, the rest keep the old revision. 0 when unset.

{{ statefulSetPartition .statefulset }}  → 2

statefulSetUpdateRevision

statefulSetUpdateRevision returns status.updateRevision — the hash of the pending update; equal to currentRevision when the rollout is complete.

{{ statefulSetUpdateRevision .statefulset }}  → "db-7a2c1d4f8"
