Cloud Metadata Discovery

This container can be run in a cloud environment to attempt to discover metadata about the Cloud Provider from the host.

Right now, only Amazon AWS and Google Cloud are supported. More cloud providers needed. Please send a Pull Request! :)

Run

Run such as:

docker run -it --rm --net=host pinpt/cloud-metadata

NOTE: You'll need to run the container on the host network to get right information.

Will return information as JSON (if found) and exit with 0 or exit with 1 if no cloud provider could be resolved.

Example output for AWS (the actual output will be compressed on one line for easier parsing):

{
  "provider":"amazonec2",
  "public_ipaddress":"50.116.21.11",
  "private_ipaddress":"10.0.1.1",
  "hostname": "ec2-50-116-21-11.us-west-2.compute.amazonaws.com",
  "zone":"us-west-2c",
  "id":"i-9912334",
  "type":"c3.xlarge"
}

Example output for Google Cloud Engine (the actual output will be compressed on one line for easier parsing):

{
	"provider":"gce",
	"hostname":"gce-test1.c.foo-9160.internal",
	"public_ipaddress":"114.197.97.113",
	"private_ipaddress":"11.128.0.2",
	"zone":"us-central1-a",
	"id":"9741257677298391091",
	"type":"n1-standard-1"
}
