Create a systemd template unit for Envoy proxies with Consul

This brief tutorial will walk through the process of creating a systemd template unit file for starting Envoy sidecars for use with Consul service mesh.

Template unit files allow systemd to address multiple units from a single configuration file. You can call a systemd template unit file using a special format to use this feature:

	# $XDG_CONFIG_HOME/k9s/alias.yml
	alias:

	udp: traefik.containo.us/v1alpha1/ingressrouteudps

	version: "3"

	# then adding a KV and taking a snapshot
	# then kill the raft DB files to simulate a storage failure
	# repeat new Vault instance, restore snapshot, unseal and auth with orig keys
	# and read some data to show how backup/restore works
