ec2metadata equivalent for Azure virtual machines

Question

Is there something similar to ec2metadata in Azure virtual machines?

I need to extract data like the the public hostname or the instance id. In Amazon EC2 instances, I can do this:

$ ec2metadata --instance-id
i-3a1dcfa3
$ ec2metadata --public-hostname
ec2-54-91-124-63.compute-1.amazonaws.com

It seems this question was asked a long time ago, so maybe you already found the answer. If not, though, then have you tried Azure Instance Metadata? (https://docs.microsoft.com/en-us/azure/virtual-machines/virtual-machines-instancemetadataservice-overview) You can do an http request like this:

curl -H Metadata:true "http://169.254.169.254/metadata/instance?api-version=2017-04-02"

The response looks like this:

              "publicIpAddress": "X.X.X.X"
            }
          ],
          "subnet": [
            {
              "address": "10.1.0.0",
              "prefix": "24"
            }
          ]
        },
        "ipv6": {
          "ipAddress": []
        },
        "macAddress": "000D3AF806EC"
      }
    ]
  }
}

Hope this helps! :)
