Product Version(s):
Calico Enterprise v3.24 EP3 (next-version docs only). The versioned version-3.24-1 and version-3.24-2 docs are left as they are.

Issue:
Related: projectcalico/calico#14208. calico-selinux is a Calico Enterprise package; Calico Open Source ships no SELinux policy. The issue stays open until the 1.2 RPMs are live.

SME review:

  • An SME has approved this change.

DOCS review:

  • A member of the docs team has approved this change.

Additional information:

From v3.24 EP3, the calico-node, calico-fluent-bit and calico-selinux RPMs are built for RHEL 9 and RHEL 10, and no longer for RHEL 8. calico-selinux 1.2 is the first version with an RHEL 10 package. It also lets calico-node start when the deny_execmem SELinux boolean is on.

Page Change
System requirements (ReqsSys.js) Lists RHEL 9 and RHEL 10. The SELinux install commands point at calico-selinux 1.2 for el9 and el10.
Non-cluster hosts (bare-metal/about.mdx) Lists RHEL 9 and RHEL 10. The RHEL 8 row is gone from the data plane table.
Upgrade with the operator, Upgrade with Helm Upgrade calico-selinux to 1.2 on el9 or el10.

For reviewers: the v3.23 docs kept RHEL 8 non-cluster hosts supported, while RHEL 8 cluster nodes were deprecated. This change ends RHEL 8 support for non-cluster hosts in v3.24. This is confirmed with PM.

Validation: Vale reports nothing on the changed lines; its remaining alerts are on lines this PR does not touch.

AI assistance: Claude Code wrote the change; reviewed by the author.

Merge checklist:

  • Deploy preview inspected wherever changes were made

Calico Enterprise 3.24 builds the calico-node, calico-fluent-bit and
calico-selinux RPMs for RHEL 9 and RHEL 10, and no longer for RHEL 8.

  for el9 or el10.
- Non-cluster hosts: list RHEL 9 and RHEL 10, and drop the RHEL 8
  iptables row from the data plane table.
- Upgrade with the operator or Helm: upgrade calico-selinux to 1.2.

Comment thread calico-enterprise/_includes/components/ReqsSys.js
- Upgrade with the operator or Helm: calico-selinux 1.2 has no RHEL 8
  build, so tell RHEL 8 users to move their nodes to RHEL 9 or 10 first.
- eBPF install: use RHEL 9 as the kOps base OS example. RHEL 8.4 does not
  meet the kernel requirement on the same page.
