Class: Aws::ElasticLoadBalancingV2::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

An API client for Elastic Load Balancing. To construct a client, you need to configure a :region and :credentials.

elasticloadbalancingv2 = Aws::ElasticLoadBalancingV2::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

See #initialize for a full list of supported configuration options.

Region

You can configure a default region in the following locations:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::ElasticLoadBalancingV2::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

#create_load_balancer(options = {}) ⇒ Types::CreateLoadBalancerOutput

Creates an Application Load Balancer or a Network Load Balancer.

When you create a load balancer, you can specify security groups, subnets, IP address type, and tags. Otherwise, you could do so later using SetSecurityGroups, SetSubnets, SetIpAddressType, and AddTags.

To create listeners for your load balancer, use CreateListener. To describe your current load balancers, see DescribeLoadBalancers. When you are finished with a load balancer, you can delete it using DeleteLoadBalancer.

You can create up to 20 load balancers per region per account. You can request an increase for the number of load balancers for your account. For more information, see Limits for Your Application Load Balancer in the Application Load Balancers Guide and Limits for Your Network Load Balancer in the Network Load Balancers Guide.

For more information, see Application Load Balancers in the Application Load Balancers Guide and Network Load Balancers in the Network Load Balancers Guide.

Options Hash (options):

  • :name (required, String)

    The name of the load balancer.

    This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.

  • :subnets (Array<String>)

    The IDs of the subnets to attach to the load balancer. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

    [Application Load Balancers] You must specify subnets from at least two Availability Zones.

  • :subnet_mappings (Array<Types::SubnetMapping>)

    The IDs of the subnets to attach to the load balancer. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

    [Network Load Balancers] You can specify one Elastic IP address per subnet.

    [Application Load Balancers] You cannot specify Elastic IP addresses for your subnets.

  • :security_groups (Array<String>)

    [Application Load Balancers] The IDs of the security groups to assign to the load balancer.

  • :scheme (String)

    The nodes of an Internet-facing load balancer have public IP addresses. The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing load balancers can route requests from clients over the Internet.

    The nodes of an internal load balancer have only private IP addresses. The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes. Therefore, internal load balancers can only route requests from clients with access to the VPC for the load balancer.

    The default is an Internet-facing load balancer.

  • :tags (Array<Types::Tag>)

    One or more tags to assign to the load balancer.

  • :type (String)

    The type of load balancer to create. The default is application.

  • :ip_address_type (String)

    [Application Load Balancers] The type of IP addresses used by the subnets for your load balancer. The possible values are ipv4 (for IPv4 addresses) and dualstack (for IPv4 and IPv6 addresses). Internal load balancers must use ipv4.

Returns:

See Also:

#create_rule(options = {}) ⇒ Types::CreateRuleOutput

Creates a rule for the specified listener. The listener must be associated with an Application Load Balancer.

Rules are evaluated in priority order, from the lowest value to the highest value. When the condition for a rule is met, the specified action is taken. If no conditions are met, the action for the default rule is taken. For more information, see Listener Rules in the Application Load Balancers Guide.

To view your current rules, use DescribeRules. To update a rule, use ModifyRule. To set the priorities of your rules, use SetRulePriorities. To delete a rule, use DeleteRule.

Examples:

Example: To create a rule


# This example creates a rule that forwards requests to the specified target group if the URL contains the specified pattern (for example, /img/*).

#create_target_group(options = {}) ⇒ Types::CreateTargetGroupOutput

Creates a target group.

To register targets with the target group, use RegisterTargets. To update the health check settings for the target group, use ModifyTargetGroup. To monitor the health of targets in the target group, use DescribeTargetHealth.

To route traffic to the targets in a target group, specify the target group in an action using CreateListener or CreateRule.

To delete a target group, use DeleteTargetGroup.

For more information, see Target Groups for Your Application Load Balancers in the Application Load Balancers Guide or Target Groups for Your Network Load Balancers in the Network Load Balancers Guide.

Options Hash (options):

  • :name (required, String)

    The name of the target group.

    This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.

  • :protocol (required, String)

    The protocol to use for routing traffic to the targets. For Application Load Balancers, the supported protocols are HTTP and HTTPS. For Network Load Balancers, the supported protocol is TCP.

  • :port (required, Integer)

    The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target.

  • :vpc_id (required, String)

    The identifier of the virtual private cloud (VPC).

  • :health_check_protocol (String)

    The protocol the load balancer uses when performing health checks on targets. The TCP protocol is supported only if the protocol of the target group is TCP. For Application Load Balancers, the default is HTTP. For Network Load Balancers, the default is TCP.

  • :health_check_port (String)

    The port the load balancer uses when performing health checks on targets. The default is traffic-port, which is the port on which each target receives traffic from the load balancer.

  • :health_check_path (String)

    [HTTP/HTTPS health checks] The ping path that is the destination on the targets for health checks. The default is /.

  • :health_check_interval_seconds (Integer)

    The approximate amount of time, in seconds, between health checks of an individual target. For Application Load Balancers, the range is 5 to 300 seconds. For Network Load Balancers, the supported values are 10 or 30 seconds. The default is 30 seconds.

  • :health_check_timeout_seconds (Integer)

    The amount of time, in seconds, during which no response from a target means a failed health check. For Application Load Balancers, the range is 2 to 60 seconds and the default is 5 seconds. For Network Load Balancers, this is 10 seconds for TCP and HTTPS health checks and 6 seconds for HTTP health checks.

  • :healthy_threshold_count (Integer)

    The number of consecutive health checks successes required before considering an unhealthy target healthy. For Application Load Balancers, the default is 5. For Network Load Balancers, the default is 3.

  • :unhealthy_threshold_count (Integer)

    The number of consecutive health check failures required before considering a target unhealthy. For Application Load Balancers, the default is 2. For Network Load Balancers, this value must be the same as the healthy threshold count.

  • :matcher (Types::Matcher)

    [HTTP/HTTPS health checks] The HTTP codes to use when checking for a successful response from a target.

  • :target_type (String)

    The type of target that you must specify when registering targets with this target group. The possible values are instance (targets are specified by instance ID) or ip (targets are specified by IP address). The default is instance. Note that you can\'t specify targets for a target group using both instance IDs and IP addresses.

    If the target type is ip, specify IP addresses from the subnets of the virtual private cloud (VPC) for the target group, the RFC 1918 range (10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16), and the RFC 6598 range (100.64.0.0/10). You can\'t specify publicly routable IP addresses.

#register_targets(options = {}) ⇒ Struct

Registers the specified targets with the specified target group.

You can register targets by instance ID or by IP address. If the target is an EC2 instance, it must be in the running state when you register it.

By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.

With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.

To remove a target from a target group, use DeregisterTargets.

Examples:

Example: To register targets with a target group


# This example registers the specified instances with the specified target group.

resp = client.register_targets({
  target_group_arn: "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067",

    The IDs of the subnets. You must specify subnets from at least two Availability Zones. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

  • :subnet_mappings (Array<Types::SubnetMapping>)

    The IDs of the subnets. You must specify subnets from at least two Availability Zones. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

    The load balancer is allocated one static IP address per subnet. You cannot specify your own Elastic IP addresses.

#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean

Waiters polls an API operation until a resource enters a desired state.

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(...) do |w|

  # disable max attempts
  w.max_attempts = nil

  # poll for 1 hour, instead of a number of attempts
  w.before_wait do |attempts, response|
    throw :failure if Time.now - started_at > 3600
  end

end

Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

Returns:

  • (Boolean)

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError)

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError)

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError)

    Raised when you request to wait for an unknown state.
