Create VM

Syntax: Create an Azure Virtual Machine

az vm create --name $VM_Name --image $VM_Image --admin-username $VM_AdminName --resource-group $RGroup --generate-ssh-keys
az vm list --resource-group $RGroup \
           --query "[].{\
                        name:name,\
                        location:location,\
                        resourceGroup:storageProfile.osDisk.managedDisk.resourceGroup,\
                        osType:storageProfile.osDisk.osType,\
                        size:hardwareProfile.vmSize,\
                        provisioningState:provisioningState\
                       }"\
           -o table

az vm show --name $VM_Name --resource-group $RGroup --show-details -o table
az vm show --name $VM_Name --resource-group $RGroup --show-details \
           --query "{name:name,\
                     location:location,\
                     powerState:powerState,\
                     publicIps:publicIps,\
                     privateIps:privateIps,\
                     adminUsername:osProfile.adminUsername\
                    }"\
           -o table

Note the public IP address

VM_PublicIp=$(az vm show --name $VM_Name --resource-group $RGroup --show-details \
                         --query "[publicIps]"\
                         -o tsv)

echo $VM_PublicIp

Inspect SSH keys
