Request for cloudflare + cache-handler

[nodesocket]

Thanks for created/hosting these pre-built images. Anyway to get acloudflare + caddyserver/cache-handler image? That would be amazing.

Hey, @nodesocket thanks! Really appreciate the kind words 🙌

Right now, I’m keeping the pre-built images simple. just Cloudflare for now to keep things lightweight and maintainable.
But the good news is: you can absolutely build your own image with cache-handler support, and
it’s designed to be super easy.

Here’s the guide you’ll want to follow:
🔧 https://github.com/CaddyBuilds/caddy-cloudflare?tab=readme-ov-file#building-your-own-docker-image

If you fork the repo, I recommend giving it a more descriptive name (since image names are based on the repo name). Something like:

caddy-cloudflare-cache
or
caddy-cacheflare (just for fun 😄)

Then in both Dockerfile and Dockerfile.alpine, after this line:

--with github.com/caddy-dns/cloudflare

just add:

--with github.com/caddyserver/cache-handler

So you’ll end up with:

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

Follow the rest of the "Build your own image" steps, and you’ll have a custom Caddy image with exactly what you need.

Let me know if you hit any bumps. Happy to help!

@vkartk thanks for the detailed instructions. Anyway to limit the arch and distribution builds? I really only need linux amd64 and linux arm64?

[nodesocket]

Humm, I triggered a GitHub action of build and push and it's been running for over 20 minutes. Is that expected?

[vkartk]

Yep, totally normal. Building all arch/platforms can take 45–60 min, so 20+ min isn’t unusual.

Right now you’d need to edit:

• .github/workflows/build-docker-image-alpine.yml
• .github/workflows/build-docker-image-standard.yml
• scripts/check_caddy_status.py

to limit it to just linux/amd64 and linux/arm64.

Good news: I’ll push an update soon so you can control platforms via GitHub vars much easier! 🚀

[nodesocket]

@vkartk ok cool. I restarted the GitHub action and sitting at 1h and 5m, but think it's stalled. Has not moved in a very long time.
