CLI

Command-Line Interface

This document is a work in progress.

Overview

Tekton provides a CLI, tkn, for easier interaction with Tekton components. It is available as a binary executable on major platforms; you may also build it from the source, or set it up as a kubectl plugin.

Installation

tkn is available on macOS via brew:

brew tap tektoncd/tools
brew install tektoncd/tools/tektoncd-cli

You can also download it as a tarball from the tkn Releases page. After downloading the file, extract it to your PATH:

# Replace YOUR-DOWNLOADED-FILE with the file path of your own.
sudo tar xvzf YOUR-DOWNLOADED-FILE -C /usr/local/bin/ tkn

tkn is available on Windows via Chocolatey:

choco install tektoncd-cli --confirm

You can also download it as a .zip file from the tkn Releases page. After downloading the file, add it to your Path:

  • Uncompress the .zip file.
  • Open Control Panel > System and Security > System > Advanced System Settings.
  • Click Environment Variables, select the Path variable and click Edit.
  • Click New and add the path to your uncompressed file.
  • Click OK.

tkn is available on Linux as a .deb package (for Debian, Ubuntu and other deb-based distros) and .rpm package (for Fedora, CentOS, and other rpm-based distros).

  • Debian, Ubuntu, and other deb-based distros

    Find the .deb package of the tkn release you would like to install on the tkn Releases page and install it with

    # Replace LINK-TO-THE-PACKAGE with the package URL you would like to use.
    rpm -Uvh LINK-TO-THE-PACKAGE

    If you are using the latest releases of Ubuntu or Debian, you may use the TektonCD CLI PPA instead:

    sudo apt update;sudo apt install -y gnupg
    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3EFE0E0A2F2F60AA
    echo "deb http://ppa.launchpad.net/tektoncd/cli/ubuntu eoan main"|sudo tee /etc/apt/sources.list.d/tektoncd-ubuntu-cli.list
    sudo apt update && sudo apt install -y tektoncd-cli
  • Fedora, CentOS, and other rpm-based distros

    Find the .rpm package of the tkn release you would like to install on the tkn Releases page and install it with

    # Replace LINK-TO-THE-PACKAGE with the package URL you would like to use.
    rpm -Uvh LINK-TO-THE-PACKAGE

    If you are using Fedora 3031, CentOS 78, EPEL, or RHEL 8, @chmousel provides an unofficial copr package repository for installing the package:

    dnf copr enable chmouel/tektoncd-cli
    dnf install tektoncd-cli

Alternatively, you may download tkn as a tarball:

Find the tarball of the tkn release for your platform (ARM or X86-64) you would like to install on the tkn Releases page and install it with

# Replace LINK-TO-TARBALL with the package URL you would like to use.
curl -LO LINK-TO-TARBALL
# Replace YOUR-DOWNLOADED-FILE with the file path of your own.
sudo tar xvzf YOUR-DOWNLOADED-FILE -C /usr/local/bin/ tkn

Build from source

If you would like to build tkn from the source, set up your Go development environment, clone the GitHub repository for tkn, and run the following commands in the cloned directory:

export GO111MODULE=on
make bin/tkn

The tkn executable will be available at /bin.

Add as a kubectl plugin

To add tkn as a kubectl plugin, run the following commands:

# The following commands assumes that your `tkn` executable is available
# at /usr/local/bin/tkn. You may need to use a different value on your
# system.
ln -s /usr/local/bin/tkn /usr/local/bin/kubectl-tkn
kubectl plugin list

If configured correctly, you should see tkn listed in the output.

Usage

Run tkn help to see the list of available commands.
