init

#!/bin/bash

# Psoxy init script - lite version
#
# Usage:
#   ./tools/init-example.sh
#   ./tools/init-example.sh <repo-root>
#
# if <repo-root> is omitted, presumes it's being run at the root of the Terraform
# configuration
#
# this is meant to be run from within a Terraform configuration for Psoxy, modeled on one of our
# examples. Copied as the `init` script in each example.
#
# this is a 'thin' version, expected to be duplicated across multiple examples and then leverage
# that 'terraform init' will do a clone of the repo, in which a longer init script will be provided
#
#
# Testing:
#   - within example directory, such as `infra/examples/aws-msft-365`:
#     ../../../tools/init-example.sh ~/code/psoxy
#
#   to repeat:
#     ../../../tools/reset-example.sh
