Wildcard SSL: module not registered: dns.providers.cloudflare

[elon_musk]

1. Caddy version (caddy version):

v2.3.0 h1:fnrqJLa3G5vfxcxmOH/+kJOcunPLhSBnjgIvjXV/QTA=

2. How I run Caddy:

a. System environment:

Ubuntu 20.04

b. Command:

xcaddy build master --with github.com/caddy-dns/cloudflare@latest
sudo systemctl restart caddy

c. Service/unit/compose file:

n/a

d. My complete Caddyfile:

{
    debug
}

darrenter.cyou, *.darrenter.cyou {
    root * /var/www/html/darrenter.cyou

    # Enable the static file server.
    file_server

    # Compress Response
    encode gzip

    log {
        output file /var/log/caddy/darrenter.cyou.access.log {
            roll_size 1gb
            roll_keep 1000
            roll_keep_for 2880h
        }
    }

    tls {
       dns cloudflare [REDACTED]
    }
}

3. The problem I’m having:

I have installed the cloudflare module via

xcaddy build master --with github.com/caddy-dns/cloudflare@latest

View the result of command here

but the dns.providers.cloudflare doesn’t listed inside caddy list-modules

For references, my DNS record configured to be:

A    darrenter.cyou    {my server ip}    DNS only
A    *                         {my server ip}     DNS only

4. Error messages and/or full log output:

 parsing caddyfile tokens for 'tls': /etc/caddy/Caddyfile:33 - Error during parsing: getting DNS provider module named 'cloudflare': module not registered: dns.providers.cloudflare

5. What I already tried:

I saw similar issue in repo of cloudflare module, the maintainer suggest to build the xcaddy with tagged release.
So I run

xcaddy build v2.2.0-rc.1 --with github.com/caddy-dns/cloudflare@latest

Instead of:

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

But I still doesn’t saw cloudflare module in list-modules

Another thing I notice with this issue is, when I run xcaddy in terminal, error message occur:

go list -m: not using modules
2021/03/31 03:18:50 [ERROR] exec [go list -m]: exit status 1: 

Not sure whether it cause the issue I face now.

Building with xcaddy fails

After your built Caddy with xcaddy, did you move the resulting binary to the correct location? xcaddy doesn’t do that for you, by default it outputs it to your current directory.

Thank you for your tips.

I solved it by move the resulting binary to /usr/bin. Now dns.providers.cloudflare is listed inside output of caddy list-modules
