tappr

tappr makes it easy to create Kubernetes clusters on your local machine and some cloud providers as well as install/manage Tanzu Application Platform installs on it. The CLI can be used by developers to do local development as well as in the CI to run end-2-end tests on a Kubernetes cluster with TAP installed.

Features

Create/Delete k8s clusters suitable for TAP deployment using tappr cluster create/tappr cluster delete commands.
- kind, minikube, and GKE are supported as of now. Other providers will be added in the future.
- GKE cluster creation requires gcloud CLI installed and configured using gcloud auth or service-accounts.
Install TAP on any K8s cluster using a single tappr tap install command.
Upgrade TAP using tappr tap upgrade command.
Setup Developer namespace for workloads creation on any TAP cluster using tappr tap setup command. This command will help setup your registry credentials, tekton test pipelines and scan policies for testing scanning supply chain.
Edit TAP installations on the fly using tappr tap edit
Easily connect your TAP GUI with other clusters in a multi-cluster environment using tappr gui track/untrack commands.
Check your local for useful utilities that are used by tappr. You can install missing ones using tappr utils local setup.
Store your credentials once, which are then seamlessly used throughout tappr commands.
