Knative Build release v0.4.0
Pre-release
Meta
Continued Transition to Pipelines
Most new development continues in the Pipelines project, now named Tekton Pipelines.
We are anticipating the first v0.1 release of Tekton Pipelines imminently, and users of Knative Build should consider Tekton Pipelines as an alternative with better support and feature richness.
Features and Bug Fixes
Removed scaling cap
Prior to #563 the Build controller would resync Build resources every 30 seconds, and enforce timeouts as part of that resync loop. However, due to rate limits consuming this queue, if enough Builds existed in the system (observed around 400 Builds), the backlog would never be processed and Builds would not be updated or timed out.
After #563 build timeout checks are scheduled in a background process, allowing us to increase the resync period to 10 hours, effectively removing the scaling cap. This also means that timeouts are enforced more promptly.
Fixed duplicate pod bug
Under some circumstances under v0.3.0, creating a Build would result in two Pods being created to execute the work. This consumed extra resources and could produce confusing or harmful side effects.
