While we don't have a docker compose example (yet), I think the diagram in our reference architecture for AWS might be useful in visualizing a HA deployment and how a client connects to targets: https://github.com/hashicorp/boundary-reference-architecture
e.g. something like a docker-compose sidecar exposing an nginx container to users via boundary would really help me understand how this is supposed to be used in practice.
Looking for an example like my comparison here between argo, wireguard, tailscale, letsencrypt, caddy, and ssh ingress: https://gist.github.com/pirate/1996d3ed6c5872b1b7afded250772...
