Motivation

When running in a dev-container on Mac Silicon, e.g. in a bookworm image,

Running uname -m on host yields arm64.

Simple devcontainer.json to reproduce:

{
    "name": "PulsarCTL",
    "image": "mcr.microsoft.com/devcontainers/base:bookworm"
}

Opening a terminal in the dev-container and running uname -m yields aarch64.

Running the install.sh script (via bash not sh and referencing v3.2.2.3 since current stable/default v3.1.0.2 has no release on arm64-linux):

version=v3.2.2.3 bash -c "$(curl -fsSL https://raw.githubusercontent.com/streamnative/pulsarctl/master/install.sh)"

Yields:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

This is due to script trying to download https://github.com/streamnative/pulsarctl/releases/download/v3.2.2.3/pulsarctl-aarch64-linux.tar.gz which should be https://github.com/streamnative/pulsarctl/releases/download/v3.2.2.3/pulsarctl-arm64-linux.tar.gz.
