Cloud HW-Info

Portable & simple HW-Info script - quickly & easily get an idea of the HW you're working on (Linux, MacOS, Windows, Public Cloud, Container, Chromebook, etc)

• good support for VMs in the public cloud (Amazon AWS, Azure, Google GCP) and containers (Kubernetes, Docker, AWS ECS, etc)
• delivered as a 1-liner, eg: useful as part of logging into any machine, such as the one in the public cloud.

Description

Provides the following information as a 1-liner:

• hostname (and domain, if appropriate)
• OS type & OS name (eg: Ubuntu) and version
• Public Cloud region/availability zone (if available)
• Distribution name (or MacOS release friendly name)
• year of OS release
• Bare Metal or VM, VM type
• are we running inside a container?
• public cloud machine type (if available)
• HW type & model (incl hypervisor type)
• How much RAM (in GB)
• How many CPUs (or cores/threads)
• Real or virtual CPUs? (CPUs vs vCPUs)
• CPU model/type and CPU speed (in GHz)
• CPU Architecture (eg: Haswell, Skylake, Ice Lake, etc)
• 32bit or 64bit system? + package type (eg: amd64)
• Local Disk sizes (in human friendly format)
• SSD (incl. NVMe) or HDD (spinning disk)?
• FS type (eg: ext4, ntfs, btrfs)
• When was the OS built? (based on dates of some key root files)

Public Cloud Support

Works well with Amazon AWS (EC2), Google Cloud (GCP) and Azure VMs:

• works out region/availability zone
• works out machine type such as: t3.medium, m5.large or e2-standard-4
• where applicable, provides extra disk information, such as "persistent-ssd" NB: uses metadata service: http://169.254.169.254/ which each hyperscaler provides

Container Support

Tries to work out if we're running under a Container, supports:

• Kubernetes (K8s)
• Docker
• AWS ECS
• Google gVisor (eg: Cloud Run)
• ... and some others

Also tries to work out any CPU or memory limits by looking at the QoS, which is usually:

• reserved/dedicated
• burstable
• besteffort

How to run directly
