Getting started with rpk on an M1

[jakthom]

TL;DR

Make sure rosetta is installed before expecting rpk to work on a mac m1 😁 .

Problem

I ran into issues after brew-installing redpanda-data/tap/redpanda and running rpk on a fresh M1:

~ ❯❯❯ brew info redpanda
redpanda-data/tap/redpanda: stable 22.1.3
Fastest Queue in the West

/opt/homebrew/Cellar/redpanda/22.1.3 (3 files, 23.5MB) *

==> Caveats
Redpanda - The fastest queue in the west!

This installs RPK which, with Docker, enables the running of a local cluster
for testing purposes.

You can start a 3 node cluster locally using the following command:

    rpk container start -n 3

You can then interact with the cluster using commands like the following:

    rpk topic list

When done, you can stop and delete the cluster with the following command:

    rpk container purge

zsh: bad CPU type in executable: rpk

Solution

Install rosetta via /usr/sbin/softwareupdate --install-rosetta (since rpk tap is an amd64 build) and things will work:

~ ❯❯❯ rpk
