Notify users that the lastImageChangeTriggeredID field in the BuildConfig spec is deprecated, and will be ignored in a future release.
BuildConfigs use the lastImageChangeTriggeredID field to record the SHA of the last image used to trigger a build. This information should only be managed by the Build controllers and be placed in the BuildConfig status. By keeping the data in spec, cluster admins and developers can easily alter or remove this information.
Why is this important?
Moving this information to status is a prerequisite for using GitOps to manage BuildConfigs with ImageChange triggers.
Stories and Deliverables
BUILD-187: Fire event if build was triggered by clearing the LastImageChangeTriggeredID
Estimate: (XS, S, M, L, XL, XXL) S
As an OpenShift engineer
I want to image change triggers to record their information BuildConfig status
So that eventually changes to ImageChange triggers in the BuildConfig spec do not cause builds to launch
As a developer using OpenShift to build images
I want to trigger a build when the base image of my application changes
So that bug fixes and security patches are applied to my application.
As an OpenShift cluster admin
I want to be alerted if something cleared the LastImageTriggeredID in a BuildConfig
So that I am aware that cluster users are relying on deprecated behavior.
1. Image change triggers record lastImageTriggeredID in the BuildConfig's status
2. Customers are notified that lastImageTriggeredID is deprecated in BuildConfig's spec
3. Customers are alerted if their users are relying on deprecated behavior
