Load custom Caddyfile from embedded app if it exists

[pierredup]

Use the embedded Caddyfile if the embedded app contains a Caddyfile at the root

Fixes #413

Nice improvement!

I left some minor comments.

Could you guys provide a simple explanation how it works? i'm using the latest builder to add caddy-exec module, created a Caddyfile in my application root folder (/app/Caddyfile) but doesn't see to work

This is my code:

Dockerfile:

FROM dunglas/frankenphp:latest-builder AS builder

# Copy xcaddy in the builder image
COPY --from=caddy:builder /usr/bin/xcaddy /usr/bin/xcaddy

# CGO must be enabled to build FrankenPHP
ENV CGO_ENABLED=1 XCADDY_SETCAP=1 XCADDY_GO_BUILD_FLAGS="-ldflags '-w -s'"
RUN xcaddy build \
	--output /usr/local/bin/frankenphp \
	--with github.com/dunglas/frankenphp=./ \
	--with github.com/dunglas/frankenphp/caddy=./caddy/ \
    --with github.com/dunglas/caddy-cbrotli \
    --with github.com/dunglas/mercure/caddy \
    --with github.com/dunglas/vulcain/caddy \
    --with github.com/abiosoft/caddy-exec

FROM dunglas/frankenphp AS runner

ENV SERVER_NAME=:80

COPY . /app
WORKDIR /app

# Replace the official binary by the one contained your custom modules
COPY --from=builder /usr/local/bin/frankenphp /usr/local/bin/frankenphp

Caddyfile

{
    exec php /app/artisan optimize
    exec php /app/artisan about
}

Should my Caddyfile be same as default and may i change adding these module commands?
