How to later add mysql datastore endpoint in k3s?

1

Cluster Datastore | K3s.

I think doing this could work(haven’t tried).

/etc/systemd/system/k3s.service

And here

ExecStart=/usr/local/bin/k3s \
    server \
        '--write-kubeconfig-mode' \
        '666' \

add

--datastore-endpoint="mysql://username:password#@tcp(192.168.1.71:3306)/K3S

This there in new line. But I am not sure if this would work. Any guidance?
