Overview

Oracle Linux 8 is Oracle's free and freely redistributable enterprise Linux distribution, binary compatible with Red Hat Enterprise Linux 8, in Premier Support to July 2029 with extended support to July 2032. This is the 64 bit Arm (AArch64) build running Oracle's Unbreakable Enterprise Kernel, for the Arm based virtual machine sizes powered by the Azure Cobalt 100 processor, which pair strong per core performance with lower cost than comparable x86 sizes.

Like every Oracle Linux image on Azure, its root filesystem lives on an LVM logical volume inside a volume group, so the root volume can be grown onto a larger disk, data volumes added and storage reshaped on a running machine with standard LVM tools. It suits teams running an Oracle Linux 8 estate that want to move web, application and container workloads onto Arm without changing distribution or tooling. Unlike Red Hat's own Arm build of this release, Oracle's kernel uses a 4 KB page size, which matters for huge page and JVM tuning; the paired guide shows how to read it rather than assume it.

This listing tracks the Oracle Linux 8 major release on Oracle's rolling repositories, so the machine keeps receiving maintenance and security updates and reports the current point release it is patched to at procurement time.

Why the cloudimg image

The cloudimg image starts from Oracle's own Arm64 image, is brought fully up to date at build time and again immediately before capture, and boots its newest kernel with superseded kernels removed. No credential is baked in: access is by the SSH key you choose at launch, password logins are off, the root password is locked, and SSH host keys, the machine id and network identity are regenerated per machine. Oracle's image lets root log in over SSH with a key; this one does not. Automatic updates are installed and armed to apply every available update and never reboot on their own, the rpcbind port Oracle's image leaves open on all four sockets is closed, and defects that left Oracle's image degraded on Azure Arm sizes are fixed: the temporary disk warning no longer fails on sizes without a temporary disk, the legacy interface renaming rule no longer fights accelerated networking, and the clock runs in UTC instead of US Eastern. SELinux stays enforcing, firewalld stays active, the tested LVM growth procedure is in the paired guide, and 24/7 support is included.

Common uses

RHEL 8 compatible application hosting on Azure Cobalt 100 Arm virtual machines
Migrating an Oracle Linux 8 x86 estate onto Arm with the same tooling
Workloads whose root or data volumes need to grow without rebuilding the machine
