第1章 Getting ready to install MicroShift
Plan for your Red Hat Device Edge by planning your Red Hat Enterprise Linux (RHEL) installation type and your MicroShift configuration.
1.1. System requirements for installing MicroShift
The following conditions must be met prior to installing MicroShift:
- A compatible version of Red Hat Enterprise Linux (RHEL). For more information, see Compatibility table.
- AArch64 or x86_64 system architecture.
- 2 CPU cores.
- 2 GB RAM. Installing from the network (UEFI HTTPs or PXE boot) requires 3 GB RAM for RHEL.
- 10 GB of storage.
- You have an active MicroShift subscription on your Red Hat account. If you do not have a subscription, contact your sales representative for more information.
- if your workload requires Persistent Volumes (PVs), you have a Logical Volume Manager (LVM) Volume Group (VG) with sufficient free capacity for the workloads.
These requirements are the minimum system requirements for MicroShift and Red Hat Enterprise Linux (RHEL). Add the system requirements for the workload you plan to run.
For example, if an IoT gateway solution requires 4 GB of RAM, your system needs to have at least 2 GB for Red Hat Enterprise Linux (RHEL) and MicroShift, plus 4 GB for the workloads. 6 GB of RAM is required in total.
It is recommended to allow for extra capacity for future needs if you are deploying physical devices in remote locations. If you are uncertain of the RAM required and if the budget permits, use the maximum RAM capacity that the device can support.
Ensure you configure secure access to the system to be able to manage it accordingly. For more information, see Using secure communications between two systems with OpenSSH.
