"""Analyze execution times of Ginkgo Ordered containers from Prow e2e junit reports.

The script fetches junit.xml artifacts from the latest N successful runs of a
Prow job, sums the durations of the individual [It] specs that belong to each
Ordered container, and writes aggregated statistics per container to a CSV file.

List all pulled images in a cluster with their supported platforms

This script lists all images that are present on any of the cluster's nodes and determines the platforms supported by the image. It uses the crane tool for detecting supported platforms.

Usage

Example usage:

timebertt

#!/bin/bash

set -o errexit
set -o nounset
set -o pipefail

extension="$(basename "$PWD")"
platform=$(echo "${extension#gardener-extension-provider-}" | sed 's/packet/equinix-metal/')

echo ">>> Revendoring $extension"
