Basic Caddy Upgrade Docker with cloudflare

Help
5

Mnaged to get over that. So adding a Dockerfile as per you example then the following in the compose:

caddy:
    container_name: caddy
    build:
      dockerfile: ${PWD}/caddy/Dockerfile
      context: ${PWD}/caddy

I ned to verify if the ${PWD} does anything, I cheated and put the full path. But this built the image an dused it with the cloudflare plugin.

So next step is understanding how to use it.

Current caddyfile has a tls section which told it my meail address and how to pull from cloudflare.
But now it seems to waht a special challenge field. But it doesn’t quite tell me where it should go:

{
	"challenges": {
		"dns": {
			"provider": "cloudflare",
			"api_token": "secret"
		}
	}
}
