Pipelines CLI (tkn) reference
The tkn CLI reference for OpenShift Pipelines
Abstract
Chapter 1. Installing tkn Copy linkLink copied to clipboard!
Use the CLI tool to manage Red Hat OpenShift Pipelines from a terminal. You can install the CLI tool on different platforms.
Both the archives and the RPMs contain the following executables:
-
tkn -
tkn-pac -
opc
Running Red Hat OpenShift Pipelines with the opc CLI tool is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
