Upgrade Notes

Difference in scale down behavior during aborts

The v1.1 abortScaleDownDelaySeconds feature now allows users full control over the scaling
behavior of the canary/preview ReplicaSet during an abort. Previously in v1.0, it was not possible
to affect this behavior. As part of this feature, v1.1 also fixes some inconsistencies in behavior
with respect to abort scale down.

The most notable change is that upon an abort, the blue-green preview ReplicaSet in v1.1 will now
scale down 30 seconds after the abort, whereas in v1.0 the preview ReplicaSet was left running
indefinitely (without any option to scale it down). If you prefer the v1.0 behavior, you can set
abortScaleDownDelaySeconds: 0, which will leave the preview ReplicaSet running indefinitely
on abort:

spec:
  strategy:
     blueGreen:
       abortScaleDownDelaySeconds: 0

Please read the full
documentation to understand
the differences in canary/preview scaling behavior for aborted Rollouts from v1.0 to v1.1.
