Image source 24/2/2023 For example some customers don’t want the builder tools and source code in a production image, while others want to be able to create a master image into which the binary application should be injected before the image progresses through testing and pre-production environments on the way to production. However some customers want to have more control over the creation of a runtime image that is to be used in production. The source to image process is fantastic for creating running applications from source code quickly to accelerate development processes. Create an instance of the builder image, with the built application, and execute the container in a pod (the purple arrow in figure 1).įigure 3 - The result of a source to image build process Creating a runtime image without source code.When the build is complete push the builder image to the OpenShift image repository (the blue arrow on figure 1).The entire build process including pulling in any dependencies takes place within the builder image. Clone the source code in the builder image and build the application (the grey box in figure 1).Create an instance of the builder image from the image repository (green arrow on figure 1).Select a builder image for the identified language from the OpenShift image repository.Examine the source code in the repository and identify the language used.The Red Hat OpenShift ‘Source to Image’ (S2I) build process is a fantastic capability that allows a developer to point OpenShift at a Git source repository and OpenShift will perform the following tasks : ![]() Source to Image Build in a Tekton pipeline Background on the Source to Image process Readers who want to see the context of a section of YAML should clone or download the Git repository and refer to the full version of the appropriate file. In an attempt to save space and make the article more readable only the important aspects of Tekton resources are included within the text. Access to the source contentĪll assets required to create your own instance of the resources described in this article can be found in the GitHub repository here. In this article the Red Hat OpenShift source 2 image process is examined in detail, and Tekton tasks are used to take advantage of source 2 image for software build and container creation. The first article in this series introduced the main concepts of Tekton and the resources that are used to construct a pipeline. OpenShift Pipelines is a Continuous Integration / Continuous Delivery (CI/CD) solution based on the open source Tekton project. Application Deployment and Pipeline Orchestration.
