az cil vnet --dns-servers

Question

I have a problem with using --dns-servers flag in az cli. When I try to update more than one DNS server it gets broken

az network vnet update \
    --name $VNET_name \
    --subscription $SUBSCRIPTION \
    --resource-group $RGRP_name \
    --dns-servers "${LOCATION[3]} ${LOCATION[4]}"

the output:

IP address is not valid '0.0.0.1 0.0.0.2'

The MS documentation says:

--dns-servers
        Space-separated list of DNS server IP addresses.

Answer 1

ok, figured it out somehow. if you use those vars stright away without closing them withing quotation marks it all works

. ./location_arrays
declare -n LOCATION='EM21'

...

az network vnet create \
    --name $VNET_name \
    --subscription $SUBSCRIPTION \
    --resource-group $RGRP_name \
    --location ${LOCATION[2]} \
    --dns-servers ${LOCATION[-2]} ${LOCATION[-1]}
