# Ghost redirects http→https when the Host header doesn't match its
# configured url, so a naive wget follows back out through Traefik
# and dies on setups without hairpin NAT. --max-redirect=0 stops
# the follow; we accept any HTTP response line as "Ghost is up".

# TCP port check. BusyBox (Alpine) wget doesn't support
# --max-redirect, so the HTTP-response approach fails; nc -z is
# universally available and answers the only question that matters
