Storing Output of Azure CLI command as variable

Edit

The command you post lost a parameter to get the private IPs, you can use the command with the parameter -d or --show-details like this:

az vm show -g resourceGrouName -n vmName -d

But this command just gets all the IPs including the secondary IP.

You can get all the VM primary IPs of each interface through a shell script like this:

count=0
while : ; do
    nic=$(az vm nic list -g resourceGroupName --vm-name vmName --query [$count].id -o tsv)
    if [[ $nic == '' ]]; then
        break
    fi
    privateIps[$count]=$(az vm nic show -g resourceGroupName --vm-name vmName --nic $nic --query ipConfigurations[0].privateIpAddress -o tsv)
    let count++

done
echo ${privateIps[*]}
