Free domain services¶
Free domain services provide users with cost-free options for registering domain names, primarily through specific providers and top-level domains (TLDs).^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md]
Freenom¶
Freenom is a widely used service that offers free domain names, with support for login via Google accounts^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md]. It is known for providing specific TLDs such as .tk, .ml, .ga, .cf, and .gq at no cost^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md].
Because these free domains must be renewed periodically to remain active, automated tools have been developed to manage them. For example, the project luolongfei/freenom provides a script or Docker-based solution to automate the renewal process for Freenom domains^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md].
SSL and HTTPS¶
To secure these domains with HTTPS, free SSL certificates are commonly used^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md]. The source material highlights Let's Encrypt as a standard solution for obtaining free SSL, often referenced alongside tools like certbot^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md].
Implementing SSL involves generating specific certificate files (e.g., certificate.crt, private.key, ca_bundle.crt) and potentially combining them into formats like .pfx for use in web servers such as Tomcat or Nginx^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md]. Validation for these certificates often requires serving files at specific paths, such as /.well-known/acme-challenge/^[400-devops__02-OS-and-Linux-Basics__network__free-domain.md].
