certbot-dns-cloudns 0.2.0

ClouDNS DNS Authenticator plugin for Certbot

The certbot-dns-clounds plugin automates the process of completing a dns-01 challenge (acme.challenges.DNS01) by creating, and subsequently removing, TXT records using the ClouDNS API.

Named Arguments

--dns-cloudns-credentials	ClouDNS credentials INI file. (Required)
--dns-cloudns-propagation-seconds	The number of seconds to wait for DNS to propagate before asking the ACME server to verify the DNS record. (Default: 60)

Credentials

Use of this plugin requires a configuration file containing the ClouDNS API credentials.

# Target user ID (see https://www.cloudns.net/api-settings/)
dns_cloudns_auth_id=1234
# Alternatively, one of the following two options can be set:
# dns_cloudns_sub_auth_id=1234
# dns_cloudns_sub_auth_user=foobar

# API password
dns_cloudns_auth_password=password1

The path to this file can be provided interactively or using the --dns-cloudns-credentials command-line argument. Certbot records the path to this file for use during renewal, but does not store the file’s contents.

Caution!

You should protect your credentials, as they can be used to potentially add, update, or delete any record in the target DNS server. Users who can read this file can use these credentials to issue arbitrary API calls on your behalf. Users who can cause Certbot to run using these credentials can complete a dns-01 challenge to acquire new certificates or revoke existing certificates for associated domains, even if those domains aren’t being managed by this server.

Certbot will emit a warning if it detects that the credentials file can be accessed by other users on your system. The warning reads “Unsafe permissions on credentials configuration file”, followed by the path to the credentials file. This warning will be emitted each time Certbot uses the credentials file, including for renewal, and cannot be silenced except by addressing the issue (e.g., by using a command like chmod 600 to restrict access to the file).
