# Red Hat Enterprise Linux (RHEL)
The documentation also applies to Red Hat derivatives, including Alma Linux, Rocky Linux, Oracle Linux, and CentOS.
## RHEL Support Subscription Registration
The content of this section does not apply to open-source derivatives.
In order to install packages via yum or dnf, RHEL 7/8 hosts are required to be registered for a valid Red Hat support subscription.
You can apply for a 1-year Development support subscription by creating a [Red Hat Developers](https://developers.redhat.com/) account. Be aware though that as the Red Hat Developers subscription is limited to only 1 year, it should not be used to register RHEL 7/8 hosts provisioned in Production environments.

If the RHEL 7/8 hosts are already registered to a valid Red Hat support subscription via an alternative configuration management approach prior to the deployment of Kubespray, the successful RHEL `subscription-manager` status check will simply result in the RHEL subscription registration tasks being skipped.
If the RHEL 8/9 hosts are already registered to a valid Red Hat support subscription via an alternative configuration management approach prior to the deployment of Kubespray, the successful RHEL `subscription-manager` status check will simply result in the RHEL subscription registration tasks being skipped.
## RHEL 8
If you have containers that are using iptables in the host network namespace (`hostNetwork=true`),
you need to ensure they are using iptables-nft.
An example how k8s do the autodetection can be found [in this PR](https://github.com/kubernetes/kubernetes/pull/82966)
The kernel version is lower than the kubenretes 1.32 system validation, please refer to the [kernel requirements](../operations/kernel-requirements.md).
