Needs how to run a quick-n-dirty local server:

# local-ish http-only file browser
# caddy hash-password
http://example.duckdns.org:3000 {
    basicauth / {
        myusername JDJhJDE0JFVMRGJ3TVR4YXlOc2x5U2N6cldPSE9kOVFaZzZ0V2JjSThySEFVbGQuTWljT0pCYVBzamk2
    }
    basicauth /* {
        myusername JDJhJDE0JFVMRGJ3TVR4YXlOc2x5U2N6cldPSE9kOVFaZzZ0V2JjSThySEFVbGQuTWljT0pCYVBzamk2
    }
    root * /Volumes/Storage/Shared/
    file_server {
      browse
    }
}

How to download caddy with a Let's Encrypt DNS-01 plugins:

• Download
• Filter Packages & Modules

Examples

• DNSimple (via Lego)
• DuckDNS

DNSimple (via Lego)

Caddy with Lego: https://caddyserver.com/download?package=github.com%2Fcaddy-dns%2Flego-deprecated

• List of supported DNS providers: https://github.com/go-acme/lego#dns-providers
• Each page will list the "provider code" as well as the necessary ENVs, such as https://go-acme.github.io/lego/dns/dnsimple/

example.com {
    tls {
        dns lego_deprecated dnsimple
    }
}

# to provide the token directly
export DNSIMPLE_OAUTH_TOKEN=xxxxxxxxx
# to provide the token from a file instead
export DNSIMPLE_OAUTH_TOKEN_FILE=/path/to/token.txt

You can put creds in a .env and run with dotenv:

dotenv -f .env -- caddy run --config Caddyfile
