Welcome to certbot_dns_ecenter’s documentation!

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

Note

The plugin is not installed by default. It can be installed by command below.

pip install certbot-dns-ecenter

Named Arguments

--dns-ecenter-credentials

Edge-Center credentials INI file. (Required)

--dns-ecenter-propagation-seconds

The number of seconds to wait for DNS

to propagate before asking the ACME server to verify the DNS record. (Default: 10)

Credentials

Use of this plugin requires a configuration file containing Edge-Center DNS API credentials. You can use Edge-Center API Token, obtained from your profile panel or use Edge-Center Authentication credentials (email and password) for login page.

Edge-Center API Token is recommended authentication option.

The token needed by Certbot for add temporary TXT record to zone what you need certificates for.

Example ecenter.ini file using restricted API Token (recommended):
# Edge-Center API token used by Certbot
dns_ecenter_apitoken = 0123456789abcdef0123456789abcdef01234567
Example ecenter.ini file using authentication credentials (not recommended):
# Edge-Center API credentials used by Certbot
dns_ecenter_email = ec_user@example.com
dns_ecenter_password = 0123456789abcdef0123456789abcdef01234

The path to this file can be provided interactively or using the --dns-ecenter-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 the password to your Edge-Center account. 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).

Also you can specify the Edge-Center auth and dns urls.

Example ecenter.ini file using alternative auth and dns urls.
 # Edge-Center API credentials used by Certbot
 dns_ecenter_auth_url = https://auth.example.com
 dns_ecenter_api_url = https://dns_api.example.com

Examples

To acquire a certificate for example.com
certbot certonly \
  --authenticator dns-ecenter \
  --dns-ecenter-credentials=./ecenter.ini \
  -d 'example.com'
To acquire a certificate for example.com, waiting 60 seconds for DNS propagation
certbot certonly \
  --authenticator dns-ecenter \
  --dns-ecenter-credentials=./ecenter.ini \
  --dns-ecenter-propagation-seconds=60 \
  -d 'example.com'
