Short script to recover etcd on crc when it gets misconfigured

fixcrc.sh

#!/bin/sh
# address CRC issues like: https://github.com/code-ready/crc/issues/1888
# run this script from the crc vm - something like (switch to id_rsa on crc <= 1.20):
# scp -i ~/.crc/machines/crc/id_ecdsa fixcrc.sh [email protected]:fixcrc.sh
# ssh -i ~/.crc/machines/crc/id_ecdsa [email protected] "chmod +x ./fixcrc.sh ; sudo ./fixcrc.sh"
