This constant is part of a private API. You should avoid using this constant if possible, as it may be removed or be changed in the future.

These are the errors we trap when attempting to talk to the instance metadata service. Any of these imply the service is not present, no responding or some other non-recoverable error.

Constructor Details

#initialize(options = {}) ⇒ ECSCredentials

Returns a new instance of ECSCredentials.

Parameters:

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :retries (Integer) — default: 5 —

    Number of times to retry when retrieving credentials.

  • :ip_address (String) — default: '169.254.170.2'
  • :port (Integer) — default: 80
  • :credential_path (String) —

    By default, the value of the AWS_CONTAINER_CREDENTIALS_RELATIVE_URI environment variable.

  • :http_open_timeout (Float) — default: 5
  • :http_read_timeout (Float) — default: 5
  • :delay (Numeric, Proc) —

    By default, failures are retried with exponential back-off, i.e. ‘sleep(1.2 ** num_failures)`. You can pass a number of seconds to sleep between failed attempts, or a Proc that accepts the number of failures.

  • :http_debug_output (IO) — default: nil —

    HTTP wire traces are sent to this object. You can specify something like $stdout.
