I’ve been trying to get a wildcard certificate for my domain for use in Caddy…

i’ve got caddy installed and working fine but it seems i need to build caddy manually to include the cloudflaredns module?

My issue is that i installed caddy using apt… so i’m not really sure what i’m meant to do now…

Does anyone have any suggestions?

    Docker is also a bit tricky, because to use a custom binary you need to build a custom image. But if you don’t mind manually installing updates it’s not too bad.

      I had it running but it didn’t seem to be issuing wildcards… but afterwards i realised that whilst i had told it to use the cloudflare API… i don’t think at any stage i’d actually told it to issue wildcards… i guess i need to figure out how to do that…

      I’m questioning my need though really… i think the docs say it’s not recommended unless you’re dealing with thousands of subdomains…

        It will only issue wildcards if you have any sites named like *.yourdomain.com, i.e. it needs to see the *. to know to issue wildcards.

        The relevant parts of my Caddyfile look like this:

        {
        	# TLS settings.
        	acme_dns cloudflare {env.CLOUDFLARE_API_TOKEN}
        	email {env.ACME_EMAIL}
        }
        
        # Proxy a subdomain to a backend server.
        # Usage: `import proxy subdomain backendHost`
        (proxy) {
        	@sub-{args.0} host {args.0}.{$DOMAIN}
        	handle @sub-{args.0} {
        		reverse_proxy http://{args.1}
        	}
        }
        
        # Put everything in the same block to get a wildcard certificate.
        *.{$DOMAIN} {
        	# Handle particular subdomains.
        	import proxy changedetection changedetection:5000
        	import proxy uptime uptime-kuma:3001
        	import proxy whoami whoami
        
        	# Fallback message (unknown subdomain).
        	handle {
        		error "This subdomain is not currently in use." 404
        	}
        }
        

        The (alias) snippet at the top is used in the site block to tell it how to use a particular subdomain.

        (I’ve removed some Authelia stuff and handling the apex domain)

        {$DOMAIN} fills in my base domain from the environment, and {env.*} does the same for my credentials (but without putting it in the JSON config).
