where can i find metadata of all the amazon cloud services?

Question

I searching for what are the metadata that AWS uses for each and every service. For AWS instance it uses ami-id, ami_launch-index, hostname, instance-action and many more as the metadata like wise where i can find metadata for all the services like EBS, VPN....

Reference Information obtained from Amazon Elastic Compute Cloud User Guide for Microsoft Windows Instances pdf pg no : 232 – 242

Answer 1

Try using AWS CLI. You can execute the describe commands of the various services to see and understand the metadata

Answer 2

I believe you are interested in knowing the properties of the each AWS Resource / Service and not the meta-data. I don't think there is a straight answer. The work around what I can recommend is using the AWS CloudFormation's Syntax definition of each AWS Resource.

For Example :

EC2 Instance is represented by the following syntax. Not all of them are mandatory. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html

Look at the KEYS of the Key:Value pair provided below [ "AvailabilityZone" : String ]

{
   "Type" : "AWS::EC2::Instance",
   "Properties" : {
      "AvailabilityZone" : String,
      "BlockDeviceMappings" : [ EC2 Block Device Mapping, ... ],
      "DisableApiTermination" : Boolean,
      "EbsOptimized" : Boolean,
      "IamInstanceProfile" : String,
      "ImageId" : String,
      "InstanceInitiatedShutdownBehavior" : String,
      "InstanceType" : String,
      "KernelId" : String,
      "KeyName" : String,
      "Monitoring" : Boolean,
      "NetworkInterfaces" : [ EC2 Network Interface, ... ],
      "PlacementGroupName" : String,
      "PrivateIpAddress" : String,
      "RamdiskId" : String,
      "SecurityGroupIds" : [ String, ... ],
      "SecurityGroups" : [ String, ... ],
      "SourceDestCheck" : Boolean,
      "SsmAssociations" : [ SSMAssociation, ... ]
      "SubnetId" : String,
      "Tags" : [ Resource Tag, ... ],
      "Tenancy" : String,
      "UserData" : String,
      "Volumes" : [ EC2 MountPoint, ... ],
      "AdditionalInfo" : String
   }
}

For VPC [http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpc.html]

{
   "Type" : "AWS::EC2::VPC",
   "Properties" : {
      "CidrBlock" : String,
      "EnableDnsSupport" : Boolean,
      "EnableDnsHostnames" : Boolean,
      "InstanceTenancy" : String,
      "Tags" : [ Resource Tag, ... ]
   }
}   

For EBS Volume [http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-ebs-volume.html]

{
   "Type":"AWS::EC2::Volume",
   "Properties" : {
      "AutoEnableIO" : Boolean,
      "AvailabilityZone" : String,
      "Encrypted" : Boolean,
      "Iops" : Number,
      "KmsKeyId" : String,
      "Size" : String,
      "SnapshotId" : String,
      "Tags" : [ Resource Tag, ... ],
      "VolumeType" : String
   }
}
