Prerequisites for Azure Kubernetes Service (AKS)

Environment Prerequisites

For a Portworx cluster on Azure Kubernetes Service (AKS), each node must meet the following hardware, software, and network requirements:

Hardware
CPU	4 cores minimum, 8 cores recommended
RAM	4GB minimum, 8GB recommended
Disk `/var` `/opt`	2GB free 3GB free
Backing drive	Use Azure Managed Disks: Standard or Premium SSDs are recommended.
Operating system root partition	64 GB is the minimum required size for the root filesystem which contains the operating system 128 GB minimum recommended
Storage drives	Azure Managed Disks or Azure Blob Storage.
Network connectivity	Bandwidth: 10 Gbps recommended 1 Gbps minimum Latency requirements for synchronous replication: less than 10ms between nodes in the cluster
Node type	Azure Virtual Machines (VMs)

Network
Open ports needed	Portworx requires open TCP ports at 9001-9022 and 9025-9029, and open UDP port at 9002. For telemetry, open ports 9024, 12001, and 12002. Ensure the network security group for your AKS nodes allows these ports.
Domain Allowlisting	For environments with locked-down network connectivity, Portworx requires the following domains to be allowlisted: `pxessentials.portworx.com:443`, `register.cloud-support.purestorage.com:443`, and `rest.cloud-support.purestorage.com:443`.

Software
Linux kernel and distro	Kernel version 3.10 or greater. Supported distributions include Ubuntu, CentOS, and Red Hat Enterprise Linux.
Key-value store	Portworx needs a key-value store for operations. You can use Azure provided managed services like Azure Database for Etcd, or deploy your own.
Disable swap	Please disable swap on all nodes that will run the Portworx software. Ensure that the swap device is not automatically mounted on server reboot.

Cloud provider	Disk types
Azure	Standard_LRS StandardSSD_LRS Premium_LRS

Before installing Portworx on AKS, ensure you are using a supported Kubernetes version:

note

K3s users: You must use CSI integration to generate/use PVCs.

Supported Kubernetes Version
AKS: 1.26.10, 1.27.7, 1.28.3, 1.29
