To request a certificate using Certbot, enter the following command:

Where:

• <domain> is a domain to include in the certificate. You can specify multiple domains using multiple -d <domain> parameters. For example:

  -d example.com -d www.example.com
• <CEG-ACME-URL> is the ACMEv2 enrollment URL used to request a certificate from Certificate Enrollment Gateway. For details, see Configuring ACMEv2 clients for enrollment with Certificate Enrollment Gateway.
• --standalone requests a certificate if you do not want to use (or do not have) existing server software. Certbot will bind on port 80 to perform domain validation. Port 80 must be available and allowed through any configured firewalls. If another application such as a Web server is running and using port 80, disable the application.
• --no-eff-email forces Certbot to not share your e-mail address with the Electronic Frontier Foundation.
• --agree-tos will cause Certbot to automatically agree to the terms of service of the ACMEv2 server (Certificate Enrollment Gateway).
• <email-address> is the email address that Certbot uses when registering the ACME account with Certificate Enrollment Gateway. Certificate Enrollment Gateway will not send email messages to this email address.
