2017/09/07 - Elastic Load Balancing - 10 updated api methods
{'Protocol': ['TCP']}
Response {'Listeners': {'Protocol': ['TCP']}}
Creates a listener for the specified Application Load Balancer or Network Load Balancer.
You can create up to 10 listeners per load balancer.
To update a listener, use ModifyListener . When you are finished with a listener, you can delete it using DeleteListener . If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer .
For more information, see Listeners for Your Application Load Balancers in the Application Load Balancers Guide and Listeners for Your Network Load Balancers in the Network Load Balancers Guide .

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 .

[REQUIRED]
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.
string
[REQUIRED]
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.
integer
[REQUIRED]
The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target.
string
[REQUIRED]
The identifier of the virtual private cloud (VPC).
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.
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.
string
[HTTP/HTTPS health checks] The ping path that is the destination on the targets for health checks. The default is /.
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.
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.
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.
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.
dict
[HTTP/HTTPS health checks] The HTTP codes to use when checking for a successful response from a target.
HttpCode (string) -- [REQUIRED]
The HTTP codes.
For Application Load Balancers, you can specify values between 200 and 499, and the default value is 200. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").
For Network Load Balancers, this is 200 to 399.
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.

(dict) --
Information about the health of a target.

The Availability Zone where the IP address is to be registered. Specify all to register an IP address outside the target group VPC with all Availability Zones that are enabled for the load balancer.

If the target state is initial , the reason code can be one of the following values:
Elb.RegistrationInProgress - The target is in the process of being registered with the load balancer.
Elb.InitialHealthChecking - The load balancer is still sending the target the minimum number of health checks required to determine its health status.
If the target state is unhealthy , the reason code can be one of the following values:
Target.ResponseCodeMismatch - The health checks did not return an expected HTTP code.
Target.Timeout - The health check requests timed out.
Target.FailedHealthChecks - The health checks failed because the connection to the target timed out, the target response was malformed, or the target failed the health check for an unknown reason.
Elb.InternalError - The health checks failed due to an internal error.
If the target state is unused , the reason code can be one of the following values:
Target.NotRegistered - The target is not registered with the target group.
Target.NotInUse - The target group is not used by any load balancer or the target is in an Availability Zone that is not enabled for its load balancer.
Target.IpUnusable - The target IP address is reserved for use by a load balancer.
Target.InvalidState - The target is in the stopped or terminated state.
If the target state is draining , the reason code can be the following value:
Target.DeregistrationInProgress - The target is in the process of being deregistered and the deregistration delay period has not expired.
Description (string) --
A description of the target health that provides additional details. If the state is healthy , a description is not provided.
{'Protocol': ['TCP']}
Response {'Listeners': {'Protocol': ['TCP']}}
Modifies the specified properties of the specified listener.
Any properties that you do not specify retain their current values. However, changing the protocol from HTTPS to HTTP removes the security policy and SSL certificate properties. If you change the protocol from HTTP to HTTPS, you must add the security policy and server certificate.
