Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/ec2_meta. To experiment with that code, run bin/console for an interactive prompt.
Add this line to your application's Gemfile:
gem 'ec2_meta'And then execute:
$ bundle
Or install it yourself as:
$ gem install ec2_meta
# without options
client = Ec2Meta.client
# with all options
client = Ec2Meta.client(
logger: Logger.new($stdout),
fail_on_not_found: true
)| name | default | description |
|---|---|---|
| logger | Ec2Meta::NullLogger.new | Pass your logger if you want |
| fail_on_not_found | false | If set true, raise error on metadata not found. |
Currently supports all of Instance metadata on Instance Metadata and User Data - Instance Metadata Categories at this time.
You can fetch meta data like below.
# fetch ami-id
client.ami_id
# fetch hostname
client.hostname
# fetch vpc_id for first network interface
client.network.interfaces.macs(0).vpc_idWhen meta data not found, return nil if fail_on_not_found is not true.
