What is Tekton’s support for dynamic task execution?
Tekton supports dynamic task execution through the use of parameterized Tasks, allowing you to define reusable tasks with dynamic inputs.
How does Tekton handle rollback strategies in pipelines?
Tekton doesn’t enforce specific rollback strategies, but you can design pipelines to include rollback tasks or use custom logic to handle rollbacks based on failure conditions.
What is the Tekton CLI (tkn), and how can I use it?
The Tekton CLI (tkn) is a command-line interface that allows you to interact with Tekton resources, trigger pipeline runs, and manage Tekton pipelines from the terminal.
How can I integrate Tekton with Jenkins?
Tekton can be integrated with Jenkins using Tekton’s Jenkinsfile Runner. This allows Jenkins users to define and run Tekton Pipelines using Jenkins declarative syntax.
What is Tekton’s support for retries and error handling?
Tekton allows you to define retries and error handling strategies within pipeline tasks, providing flexibility in managing failures and retries.
Can Tekton be used for building container images?
Yes, Tekton provides tasks and resources for building container images using tools like Buildah or Docker. You can integrate image-building tasks into your pipelines.
How does Tekton support self-hosted runners or build agents?
Tekton allows you to use self-hosted runners or build agents by deploying them as part of your Kubernetes cluster or using Kubernetes nodes as build agents.
What is Tekton’s support for declarative pipeline definitions?
Tekton uses YAML-based pipeline definitions, making it a declarative approach to defining CI/CD pipelines. Pipeline resources, tasks, and conditions are specified in YAML.
How can I manage Tekton pipeline configurations in version control?
Tekton pipeline configurations can be managed in version control systems like Git, allowing you to store and version your pipeline definitions as code.
What is the Tekton EventListener, and how can it be used?
Tekton EventListener is a component that listens for events, such as code commits or pull requests, and triggers the execution of Tekton Pipelines in response.
