Install IPFS (Kubo) on Alpine Linux (NOT on Docker)

This document describes how to install and update IPFS (Kubo, fka go-ipfs) on Alpine Linux and not on Docker container image.

We have found that it is more stable to build from source and update with the gup command.

• Tested on: Alpine 3.16

How to create/generate a cluster secret of IPFS cluster

The cluster secret must be exactly 64 characters and contain only hexadecimal characters ([0-9a-f]). (from "cluster_config.go" | ipfs-cluster @ GitHub)

So, we just need to generate a 64 character in hex.

$ od -vN 32 -An -tx1 /dev/urandom | tr -d ' \n'
