# Example KPT ROOT DIR:
# ~/go/src/github.com/GoogleContainerTools/kpt
#
# Flags:
# -b) Build the kpt binary with dependencies at HEAD. Downloads HEAD
# for cli-utils and kustomize repositories, and builds kpt using
# these downloaded repositories.
# -k) Run against this Kubernetes version. Creates a local Kubernetes
# cluster at this version using "kind". Only accepts MAJOR.MINOR.
# Example: 1.17. This is translated to a patch version. Example:
# 1.17 runs version 1.17.11.
#
# Prerequisites (must be in $PATH):
# kind - Kubernetes in Docker
# kubectl - version of kubectl should be within +/- 1 version of cluster.
# CHECK: kubectl version
# CHECK: $ kubectl version
#
# Examples:
# $ ./e2e/live/end-to-end-test.sh -b
# $ ./e2e/live/end-to-end-test.sh -v 1.17
# $ ./e2e/live/end-to-end-test.sh -bv 1.17
