loopy

Overview

A Kubernetes packaging helper utility that tries to prevent you from going loopy.

It's useful for those times when you find yourself testing the same inner loop like repeatedly installing and upgrading the same set of Helm charts on a kind cluster after only a couple lines of changes to a values file.

Installation

• For Rust users, loopy is available with cargo.

bash cargo install loopy

• For everyone else, pre-packaged binaries are available in releases.

Usage

Once you have loopy installed, there are couple of things you need to do to get up and running.

• Create the folder structure.

```bash

Where you want to store your loopy configuration.

LOOPY_HOME="${HOME}/loopy"

Create the folder structure.

mkdir --parents "${LOOPY_HOME}/config/{capi,helm,manifests,carvel}"

cd "${LOOPY_HOME}" ```

• Define your configuration in loopy.yaml

```bash

If you need a starter sample.

curl --output "${LOOPY_HOME}/loopy.yaml" https://raw.githubusercontent.com/salt-labs/loopy/trunk/config/loopy.yaml

vim loopy.yaml ```

• If you need a kind cluster for local testing, there is a sample configuration in the config/capi/kind directory with usage instructions in the kind section.

• Before continuing, ensure you are connected to the cluster.

bash kubectl cluster-info

• Review the available commands.

bash loopy --help

• When ready, run loopy

bash loopy --config loopy.yaml --action install

• When finished, run loopy again to clean up.

bash loopy --config loopy.yaml --action uninstall

Dependencies

If you don't already have the dependencies installed, loopy will ask to install them for you if you are internet connected.

Once that's done you can add the vendor folder to the PATH of your current shell and go from there.

bash export PATH=$(pwd)/vendor:$PATH
