findskus

findsku

CLI for filtering Azure SKUs and regions.

Motivation

The two commands az vm list-skus and az account locations are very slow (roughly 15 seconds to 2 minutes per region for list-skus) and difficult to use for analysis.

The goal of this tool is to cache the results of the Azure CLI requests, then allow fast analysis to compare regions and find SKUs matching filtering criteria.

Security consideration

This tool uses az vm list-skus and az account locations.

Obviously I trust this tool since I wrote it myself. But you should really not trust tools like these.

[!WARNING] It is highly recommended that you create a SP with Reader access to the Subscription and run the tool in an isolated environment.

Pre-requisites

• Access to /tmp
• Azure CLI (az in the path)
• Azure CLI login session (az login)

Installation

For now, only installable with Go:

go install github.com/sebnyberg/findskus@latest

Usage

[!IMPORTANT] On the first run, locations will be (slowly) downloaded from azure to a directory in /tmp. To view progress, run in verbose mode with -v.

First run

The first run (and location) will cache results from Azure. View progress with -v.

After changing the subscription, you should re-download data with: --redownload:

findsku --redownload [...]

Finding SKUs

Find SKUs with 16GB RAM in West Europe:

findsku --memory 16 --encryption-at-host -l westeurope

Find SKUs in any region with at least 64 vCPUs that are available for use:

findsku --min-cpu 64

Find all SKUs with accelerated networking in southcentralus or westus, output as JSON.

findsku --accelerated-networking --min-memory 32 -l southcentralus,westus -o json

Listing location statistics

To view location statistics, add --by-location:

findsku --min-memory 16 --max-memory 32 --encryption-at-host --by-location

Find locations that has premium IO in at least two availability zones:

findsku --premium-io --min-zones 2 --by-location
