I asked myself the same question before. If only caddy had an official image with the cloudflare plugin, so we wouldn’t have to build ourselves or trust 3rd party providers. But oh well, if you have any other custom image, you might as well build caddy as well.

I’m not entirely sure, but I think you can skip the “–no-cache” as it seems to still check for image updates. It helps to speed things up, especially if you check for updates more frequently.

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 💜.
