labels
map (key: string, value: string)
Optional. Unstructured key value map that can be used to organize and categorize objects.
An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
annotations
map (key: string, value: string)
Optional. Unstructured key value map that may be set by external tools to store and arbitrary metadata. They are not queryable and should be preserved when modifying objects.
An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
uid
string
Output only. System-assigned, unique identifier.
etag
string
Output only. Server-computed checksum based on other values; may be sent on update or delete to ensure operation is done on expected resource.
Rollout.State
The state of the rollout.
Enums
STATE_UNSPECIFIED
The rollout is in an unknown state.
QUEUED
The rollout is waiting for actuation to begin. This may be because it is waiting on another rollout to complete.
PENDING_BUILD
The rollout is waiting for the build process to complete, which builds the code and sets up the underlying infrastructure.
PROGRESSING
The rollout has started and is actively modifying traffic.
SUCCEEDED
The rollout has completed.
FAILED
The rollout has failed. See error for more information.
