Tekton
With Tekton, each operation in your CI/CD workflow becomes a Step, which is executed with a container image you specify. Steps are then organized in Tasks, which run as a Kubernetes pod in your cluster. You can further organize Tasks into Pipelines, which can control the order of execution of several Tasks.
