tekton-install

tekton-install is a CLI for installing Tekton components (pipeline, triggers, and dashboard) on a Kubernetes cluster. It currently supports installing and uninstalling individual components of Tekton. By default, it will install the latest version of each component, but it also adds flags to allow users to specify specific versions to install.

There is currently no validation of whether or not certain versions of components are compatible, so please make sure to verify component versions will work with one another before installing certain version combinations.

Prerequisites

• kubectl must be installed - As of now, tekton-install is simply a wrapper around kubectl to pass arguments to kubectl apply -f and kubectl delete -f commands.
• A Kubernetes cluster version 1.15 or higher for Tekton Pipelines v0.11.0 or higher, or a Kubernetes cluster version 1.11 or higher for Tekton releases before v0.11.0.

Shell Autocompletion

Similar to kubectl's shell autocompletion approach, tekton-install features a completion command to enable autocompletion for bash and zsh.

Bash

For both Linux and macOS, installing bash-completion is required.

Linux

Use one of the approaches below to enable shell autocompletion for tekton-install on a Linux distribution.

To add the script to your .bashrc file:

echo 'source <(tekton-install completion bash)' >>~/.bashrc

Add the completion script to the /etc/bash_completion.d directory:

tekton-install completion bash >/etc/bash_completion.d/tekton-install

After completing the steps above, refresh your terminal to start using autocompletion.

Mac

Add the following to your ~/.bash_profile file:

export BASH_COMPLETION_COMPAT_DIR="/usr/local/etc/bash_completion.d"
[[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh"

Use one of the approaches below to enable shell autocompletion for tekton-install on macOS.

To add the script to your .bash_profile:

echo 'source <(tekton-install completion bash)' >>~/.bash_profile

Add the completion script to the /usr/local/etc/bash_completion.d directory:

tekton-install completion bash >/usr/local/etc/bash_completion.d/tekton-install

After completing the steps above, refresh your terminal to start using autocompletion.

Zsh
