certbot-dns-clouddns

The ~certbot_dns_clouddns.dns_clouddns plugin automates the process of completing a dns-01 challenge (~acme.challenges.DNS01) by creating, and subsequently removing, TXT records using the CloudDNS REST API.

Named Arguments

--authenticator certbot-dns-clouddns:dns-clouddns	Select the plugin. (Required)
--certbot-dns-clouddns:dns-clouddns-credentials	CloudDNS Remote API credentials INI file. (Required)
--certbot-dns-clouddns:dns-clouddns-propagation-seconds	The number of seconds to wait for DNS to propagate before asking the ACME server to verify the DNS record. (Default: 60)

Installation

certbot-dns-clouddns requires Python 2.7 or 3.5+ to run.

pip3 install certbot-dns-clouddns

Credentials

Use of this plugin requires a configuration file containing CloudDNS Remote API . You can find out the clientId by running the following command:

curl --silent --request POST https://admin.vshosting.cloud/api/public/auth/login \
--data '{"email":"<email>","password":"<password>"}' \
--header "Content-Type: application/json" \
  | grep --perl-rexexp --only-matching '"clientId": \K"[^"]"' \
  | head -n 1 \
  | tr -d '"'

Example credentials file:

# CloudDNS API credentials used by Certbot
certbot_dns_clouddns:dns_clouddns_clientId = myclientid
certbot_dns_clouddns:dns_clouddns_email = myemailaddress
certbot_dns_clouddns:dns_clouddns_password = mysecretpassword

The path to this file can be provided interactively or using the --certbot-dns-clouddns:dns-clouddns-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 these API credentials as you would a password. Users who can read this file can use these to issue arbitrary CloudDNS 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).

Examples

To acquire a certificate for example.com

certbot certonly \
  --authenticator certbot-dns-clouddns:dns-clouddns \
  --certbot-dns-clouddns:dns-clouddns-credentials ~/.secrets/certbot/clouddns.ini \
  -d example.com

To acquire a single certificate for both example.com and *.example.com

certbot certonly \
  --authenticator certbot-dns-clouddns:dns-clouddns \
  --certbot-dns-clouddns:dns-clouddns-credentials ~/.secrets/certbot/clouddns.ini \
  -d example.com \
  -d '*.example.com'

To acquire a certificate for example.com, waiting 240 seconds for DNS propagation

certbot certonly \
  --authenticator certbot-dns-clouddns:dns-clouddns \
  --certbot-dns-clouddns:dns-clouddns-credentials ~/.secrets/certbot/clouddns.ini \
  --certbot-dns-clouddns:dns-clouddns-propagation-seconds 240 \
  -d example.com
