# Provision an application for a user for IndiePaaS
#
# This file:
# - Registers the domain name to NameCheap
# - Generates the TLS certificate associated
# - Configures the DNS
# - Configures the mail forwarding
# - Starts the application
#
# Version 0.0.2
#
# Authors:
# - Pierre Ozoux (pierre-o.fr)

# Usage:
# LOG_LEVEL=7 ./provision.sh -e test@test.org -a known -u example.org -g -b -c
#
# Licensed under AGPLv3
### Configuration
#####################################################################
# Environment variables and their defaults
LOG_LEVEL="${LOG_LEVEL:-6}" # 7 = debug -> 0 = emergency
# Commandline options. This defines the usage page, and is used to parse cli
# opts & defaults from. The parsing is unforgiving so be precise in your syntax
read -r -d '' usage <<-'EOF'
