Cloudflare plugin error

Hi

I cant install caddy docker with cloudflare plugin. Here is the error output:

`docker build --build-arg plugins=git,cloudflare github.com/abiosoft/caddy-docker.git

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

same here with gandiv5 plugin:
caddyserver/caddy#2385

[grugnog]

I think the issue is that builder (at https://github.com/abiosoft/caddy-docker/blob/master/builder/builder.sh#L34 maybe) and caddyplug (which it is using to map plugin names to packages) don't have a way to specify versions for plugin dependencies or even plugin versions.
Note that https://github.com/mholt/caddy/blob/master/vendor/manifest#L170 is pointing to the lego commit prior to the breaking one, but that isn't being used in the builder build process.

[abiosoft]

This has been fixed. docker rmi abiosoft/caddy:builder and try again.
