Which caddy docker builds to use? (piefed.social)

I'm looking into setting up https for my local services. Everything is currently set up using the official caddy docker image.

I want to use now connect caddy to cloudflare to resolve the DNS 01. It looks like this is possible with a drop in replacement for caddy from either https://github.com/CaddyBuilds/caddy-cloudflare or https://github.com/serfriz/caddy-custom-builds

Is anyone here using these builds? Are they reliable? Is there an alternative I havent considered?

I have a Dockerifle:

ARG CADDY_VERSION=2.11.3
FROM caddy:${CADDY_VERSION}-builder-alpine AS builder

RUN xcaddy build \
    --with github.com/caddy-dns/cloudflare

FROM caddy:${CADDY_VERSION}-alpine

COPY --from=builder /usr/bin/caddy /usr/bin/caddy

and the docker-compose.yml file I have this snippet at the top, of course this isn't the full file as there are specifics to my usecase in my full yml:

services:
  caddy:
    pull_policy: build
    build:
      context: .

And to build new versions I modify the Dockerfile after doing a docker compose down, and then to build the new version I use docker compose up.``

Though this is outdated for my current setup, as I also use github.com/lucaslorentz/caddy-docker-proxy by adding "--with github.com/lucaslorentz/caddy-docker-proxy/v2" below where I added the Cloudflare repo.

This is so I can use Docker Labels to to automate entries.

Note that the (non-windows) caddy and caddy: builder images are all alpine based. The "-alpine" tags point to the same images (as you can tell by the hashes). But some like to be explicit about it ๐Ÿ’œ.
