# Caddyfile for the blog behind Cloudflare.

# Topology: Cloudflare (terminates TLS) -> Caddy (HTTP :80) -> SWS (blog:80)
|
||
|
|
#
|
||
|
|
# Cloudflare handles the public HTTPS cert, so Caddy serves plain HTTP on :80
|
||
|
|
# and does NOT need the Cloudflare DNS-01 / automatic-HTTPS setup. Set the
|
||
|
|
# Cloudflare SSL/TLS mode to "Full" so CF->origin is encrypted at the network
|
||
|
|
# layer (e.g. over your tunnel/Netbird), even though this listener is HTTP.
|
||
|
|
#
|
||
|
|
# Copy this file to /etc/caddy/Caddyfile on the caddy_cf host and reload:
|
||
|
|
# docker exec caddy_cf caddy reload --config /etc/caddy/Caddyfile
|
||
|
|
# or restart the container.
