Rocky Linux Agent

The prerequisites for Rocky are exactly the same as for CentOS and Red Hat.

For Rocky Linux, the Linux agent usually doesn’t have special requirements beyond standard RHEL compatibility, since Rocky is binary compatible with RHEL. You just need basic things like root/sudo access, supported kernel version, and required network connectivity to the manager. Also make sure required packages like curl, tar, and openssl are available. If the docs don’t mention Rocky specifically, you can generally follow the RHEL/CentOS installation steps safely.
