Azure CLI - list ip-addresses & show Azure Network Security Group & create Azure NSG rule

A few basic tasks in Microsoft Azure via CLI.  In order to use microsegmentation or zero-trust-networking in Azure (which I highly recommend), I recommend to work with Azure Network Security Groups.

List Azure VM ip-addresses

Azure:~$
Azure:~$ az vm list-ip-addresses
[
  {
    "virtualMachine": {
      "name": "my-vm",
      "network": {
        "privateIpAddresses": [
          "10.0.0.4"
        ],
        "publicIpAddresses": [
          {
            "id": "/subscriptions/9aaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa7/resourceGroups/learn-f00f00f0-f00f-f00f-f00f-f00f00f00f00/providers/Microsoft.Network/publicIPAddresses/my-vmPublicIP",
            "ipAddress": "13.64.0.1",
            "ipAllocationMethod": "Dynamic",
            "name": "my-vmPublicIP",
            "resourceGroup": "learn-f00f00f0-f00f-f00f-f00f-f00f00f00f00"
          }
        ]
      },
      "resourceGroup": "learn-f00f00f0-f00f-f00f-f00f-f00f00f00f01"
    }
  }
] 

Azure:~$
Azure:~$ 

Put IP-address of VM in variable

IPADDRESS="$(az vm list-ip-addresses \
  --resource-group learn-f00f00f0-f00f-f00f-f00f-f00f00f00f00 \
  --name my-vm \
  --query "[].virtualMachine.network.publicIpAddresses[*].ipAddress" \
  --output tsv)"

Azure:~$
Azure:~$ IPADDRESS="$(az vm list-ip-addresses \
>   --resource-group learn-f00f00f0-f00f-f00f-f00f-f00f00f00f00 \
>   --name my-vm \
>   --query "[].virtualMachine.network.publicIpAddresses[*].ipAddress" \
>   --output tsv)"
Azure:~$
Azure:~$
Azure:~$ echo $IPADDRESS
13.64.0.1
Azure:~$
Azure:~$
Azure:~$ curl --connect-timeout 5 http://$IPADDRESS
curl: (28) Connection timed out after 5000 milliseconds

Show Azure Network Security Group

Azure:~$
Azure:~$ az network nsg list \
>   --resource-group learn-f00f00f0-f00f-f00f-f00f-f00f00f00f00 \
>   --query '[].name' \
>   --output tsv
my-vmNSG
Azure:~$
Azure:~$

Azure Network Security Group Name = my-vmNSG

What is defined in Network Security Group Name my-vmNSG?

Azure:~$
Azure:~$
Azure:~$ az network nsg rule list \
>   --resource-group learn-f00f00f0-f00f-f00f-f00f-f00f00f00f00 \
>   --nsg-name my-vmNSG

Show again that JSON formated by Name, Prio, Dst-Port & Access-Action:

Azure:~$
Azure:~$ az network nsg rule list \

Create Azure Network Security Group Rule for HTTP
