Organizations rely on Docker’s portability, scalability, and automation capabilities to ease container creation and management. Docker proficiency is crucial for anyone involved in application development and will enhance your employability as a job seeker or software developer. Tekton provides a set of Kubernetes-native resources for defining and running containerized tasks and pipelines. Tekton resources can be used to build Docker images, push Docker images to a registry, and deploy Docker images to a Kubernetes cluster.

In this hands-on guided project, you will learn how to build and push a Docker image to the image registry. Then, learn how to check for ClusterTasks, add a workspace to the Pipeline Task, and reference the Buildah Task. Next, you’ll gain hands-on experience updating the task parameters, checking your work, applying changes, and running the pipeline.

After completing this project, you’ll have experience with Docker images and pipelines, including establishing a pipeline, and building an image with Tekton using a code repository.
