The Red Hat Developer Subscription for Individuals is a single subscription, which allows the user to install Red Hat Enterprise Linux on a maximum of 16 systems, physical or virtual, regardless of system facts and size. Those 16 nodes may be used by the individual developer for demos, prototyping, QA, small production uses, and cloud access. For more details, please visit this page https://developers.redhat.com/articles/faqs-no-cost-red-hat-enterprise-linux#general To register with this program: https://developers.redhat.com/register/ Once you have successfully registered with this one then you could activate the subscription and download required packages. Alternatively, you may attach ISO image (if available) and create a local yum/dnf repository and download/avaiable packages from the image. All the best!
