Chapter 1. Installing tkn

Use the CLI tool to manage Red Hat OpenShift Pipelines from a terminal. You can install the CLI tool on different platforms.

Note

Both the archives and the RPMs contain the following executables:

  • tkn
  • tkn-pac
  • opc
Important

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.

For Linux distributions, you can download the CLI as a tar.gz archive.

    $ echo $PATH
