링크 복사

Before you can install Red Hat Advanced Cluster Security Cloud Service, your system must meet several requirements.

주의

You must not install RHACS Cloud Service on:

Amazon Elastic File System (Amazon EFS). Use the Amazon Elastic Block Store (Amazon EBS) with the default gp2 volume type instead.
Older CPUs that do not have the Streaming SIMD Extensions (SSE) 4.2 instruction set. For example, Intel processors older than Sandy Bridge and AMD processors older than Bulldozer. These processors were released in 2011.

To install RHACS Cloud Service, you must have one of the following systems:

OpenShift Container Platform version 4.12 or later, and cluster nodes with a supported operating system of Red Hat Enterprise Linux CoreOS (RHCOS) or Red Hat Enterprise Linux (RHEL)
A supported managed Kubernetes platform, and cluster nodes with a supported operating system of Amazon Linux, CentOS, Container-Optimized OS from Google, Red Hat Enterprise Linux CoreOS (RHCOS), Debian, Red Hat Enterprise Linux (RHEL), or Ubuntu
For information about supported platforms and architecture, see the Red Hat Advanced Cluster Security for Kubernetes Support Matrix.

The following minimum requirements and suggestions apply to cluster nodes.

Architecture: Supported architectures are amd64, ppc64le, or s390x.
참고
Secured cluster services are supported on IBM Power (ppc64le), IBM Z (s390x), and IBM® LinuxONE (s390x) clusters.
Processor: 3 CPU cores are required.
Memory: 6 GiB of RAM is required.
참고
See the default memory and CPU requirements for each component and ensure that the node size can support them.
Storage: For RHACS Cloud Service, a persistent volume claim (PVC) is not required. However, a PVC is strongly recommended if you have secured clusters with Scanner V4 enabled. Use Solid-State Drives (SSDs) for best performance. However, you can use another storage type if you do not have SSDs available.
중요
You must not use Ceph FS storage with RHACS Cloud Service. Red Hat recommends using RBD block mode PVCs for RHACS Cloud Service.

If you plan to install RHACS Cloud Service by using Helm charts, you must meet the following requirements:

You must have Helm command-line interface (CLI) v3.2 or newer, if you are installing or configuring RHACS Cloud Service using Helm charts. Use the helm version command to verify the version of Helm you have installed.
You must have access to the Red Hat Container Registry. For information about downloading images from registry.redhat.io, see Red Hat Container Registry Authentication.
