Chapter 1. Builds for Red Hat OpenShift release notes

Release notes contain information about new and deprecated features, breaking changes, and known issues. The following release notes apply for the most recent Builds releases on OpenShift Container Platform.

Builds is an extensible build framework based on the Shipwright project, which you can use to build container images on an OpenShift Container Platform cluster. You can build container images from source code and Dockerfiles by using image build tools, such as Source-to-Image (S2I) and Buildah. You can create and apply build resources, view logs of build runs, and manage builds in your OpenShift Container Platform namespaces.

Builds includes the following capabilities:

  • Standard Kubernetes-native API for building container images from source code and Dockerfiles
  • Support for Source-to-Image (S2I) and Buildah build strategies
  • Extensibility with your own custom build strategies
  • Execution of builds from source code in a local directory
  • Shipwright CLI for creating and viewing logs, and managing builds on the cluster
  • Integrated user experience with the Developer perspective of the OpenShift Container Platform web console

For more information about Builds, see Overview of Builds.

The following list highlights fixed issues in Builds 1.6.

Fixed duplicate installation of OpenShift Pipelines Operator
Before this update, the Builds for Red Hat OpenShift Operator automatically installed the Red Hat OpenShift Pipelines Operator. However, if an older version of the OpenShift Pipelines Operator was already present, it caused a conflict because the Builds Operator attempted to install another instance of the OpenShift Pipelines Operator. With this update, the Builds Operator no longer installs the OpenShift Pipelines Operator automatically. You must now install the OpenShift Pipelines Operator before installing the Builds Operator.
