Constructor Details

#initialize(options = {}) ⇒ Real

Initialize connection to ELB

Notes

options parameter must include values for :aws_access_key_id and :aws_secret_access_key in order to create a connection

Examples

elb = ELB.new(
 :aws_access_key_id => your_aws_access_key_id,
 :aws_secret_access_key => your_aws_secret_access_key
)

Parameters

  • options<~Hash> - config arguments for connection. Defaults to {}.

    • region<~String> - optional region to use, in [‘eu-west-1’, ‘us-east-1’, ‘us-west-1’, ‘ap-northeast-1’, ‘ap-southeast-1’]

Returns

  • ELB object with connection to AWS.

Instance Method Details

#configure_health_check(lb_name, health_check) ⇒ Object

Enables the client to define an application healthcheck for the instances. See docs.amazonwebservices.com/ElasticLoadBalancing/latest/APIReference/index.html?API_ConfigureHealthCheck.html

Parameters

  • lb_name<~String> - Name of the ELB

  • health_check<~Hash> - A hash of parameters describing the health check

    • ‘HealthyThreshold’<~Integer> - Specifies the number of consecutive health probe successes required before moving the instance to the Healthy state.

    • ‘Interval’<~Integer> - Specifies the approximate interval, in seconds, between health checks of an individual instance.

    • ‘Target’<~String> - Specifies the instance being checked. The protocol is either TCP or HTTP. The range of valid ports is one (1) through 65535.

    • ‘Timeout’<~Integer> - Specifies the amount of time, in seconds,

    during which no response means a failed health probe.

    • ‘UnhealthyThreshold’<~Integer> - Specifies the number of consecutive health probe failures required before moving the instance to the Unhealthy state.

Returns

  • response<~Excon::Response>:

    • body<~Hash>:
