Gets and sets the property Key.
The name of the attribute.
The following attributes are supported by all load balancers:
deregistration_delay.timeout_seconds - The amount of time, in seconds, for
Elastic Load Balancing to wait before changing the state of a deregistering target
from draining to unused . The range is 0-3600 seconds. The default value
is 300 seconds. If the target is a Lambda function, this attribute is not supported.
stickiness.enabled - Indicates whether target stickiness is enabled. The value
is true or false . The default is false .
stickiness.type - Indicates the type of stickiness. The possible values are:
lb_cookie and app_cookie for Application Load Balancers.
source_ip for Network Load Balancers.
source_ip_dest_ip and source_ip_dest_ip_proto for Gateway Load Balancers.
The following attributes are supported by Application Load Balancers and Network Load
Balancers:
load_balancing.cross_zone.enabled - Indicates whether cross zone load balancing
is enabled. The value is true , false or use_load_balancer_configuration .
The default is use_load_balancer_configuration .
target_group_health.dns_failover.minimum_healthy_targets.count - The minimum
number of targets that must be healthy. If the number of healthy targets is below
this value, mark the zone as unhealthy in DNS, so that traffic is routed only to healthy
zones. The possible values are off or an integer from 1 to the maximum number
of targets. The default is off .
target_group_health.dns_failover.minimum_healthy_targets.percentage - The
minimum percentage of targets that must be healthy. If the percentage of healthy targets
is below this value, mark the zone as unhealthy in DNS, so that traffic is routed
only to healthy zones. The possible values are off or an integer from 1 to
100. The default is off .
target_group_health.unhealthy_state_routing.minimum_healthy_targets.count
- The minimum number of targets that must be healthy. If the number of healthy targets
is below this value, send traffic to all targets, including unhealthy targets. The
possible values are 1 to the maximum number of targets. The default is 1.
target_group_health.unhealthy_state_routing.minimum_healthy_targets.percentage
- The minimum percentage of targets that must be healthy. If the percentage of healthy
targets is below this value, send traffic to all targets, including unhealthy targets.
The possible values are off or an integer from 1 to 100. The default is off .
The following attributes are supported only if the load balancer is an Application
Load Balancer and the target is an instance or an IP address:
load_balancing.algorithm.type - The load balancing algorithm determines how
the load balancer selects targets when routing requests. The value is round_robin ,
least_outstanding_requests , or weighted_random . The default is round_robin .
load_balancing.algorithm.anomaly_mitigation - Only available when load_balancing.algorithm.type
is weighted_random . Indicates whether anomaly mitigation is enabled. The value
is on or off . The default is off .
slow_start.duration_seconds - The time period, in seconds, during which a
newly registered target receives an increasing share of the traffic to the target
group. After this time period ends, the target receives its full share of traffic.
The range is 30-900 seconds (15 minutes). The default is 0 seconds (disabled).
stickiness.app_cookie.cookie_name - Indicates the name of the application-based
cookie. Names that start with the following prefixes are not allowed: AWSALB ,
AWSALBAPP , and AWSALBTG ; they're reserved for use by the load balancer.
stickiness.app_cookie.duration_seconds - The time period, in seconds, during
which requests from a client should be routed to the same target. After this time
period expires, the application-based cookie is considered stale. The range is 1 second
to 1 week (604800 seconds). The default value is 1 day (86400 seconds).
stickiness.lb_cookie.duration_seconds - The time period, in seconds, during
which requests from a client should be routed to the same target. After this time
period expires, the load balancer-generated cookie is considered stale. The range
is 1 second to 1 week (604800 seconds). The default value is 1 day (86400 seconds).
The following attribute is supported only if the load balancer is an Application Load
Balancer and the target is a Lambda function:
lambda.multi_value_headers.enabled - Indicates whether the request and response
headers that are exchanged between the load balancer and the Lambda function include
arrays of values or strings. The value is true or false . The default
is false . If the value is false and the request contains a duplicate
header field name or query parameter key, the load balancer uses the last value sent
by the client.
The following attributes are supported only by Network Load Balancers:
deregistration_delay.connection_termination.enabled - Indicates whether the
load balancer terminates connections at the end of the deregistration timeout. The
value is true or false . For new UDP/TCP_UDP target groups the default
is true . Otherwise, the default is false .
preserve_client_ip.enabled - Indicates whether client IP preservation is enabled.
The value is true or false . The default is disabled if the target group
type is IP address and the target group protocol is TCP or TLS. Otherwise, the default
is enabled. Client IP preservation cannot be disabled for UDP and TCP_UDP target groups.
proxy_protocol_v2.enabled - Indicates whether Proxy Protocol version 2 is
enabled. The value is true or false . The default is false .
target_health_state.unhealthy.connection_termination.enabled - Indicates whether
the load balancer terminates connections to unhealthy targets. The value is true
or false . The default is true .
target_health_state.unhealthy.draining_interval_seconds - The amount of time
for Elastic Load Balancing to wait before changing the state of an unhealthy target
from unhealthy.draining to unhealthy . The range is 0-360000 seconds.
The default value is 0 seconds.
Note: This attribute can only be configured when target_health_state.unhealthy.connection_termination.enabled
is false .
The following attributes are supported only by Gateway Load Balancers:
target_failover.on_deregistration - Indicates how the Gateway Load Balancer
handles existing flows when a target is deregistered. The possible values are rebalance
and no_rebalance . The default is no_rebalance . The two attributes (target_failover.on_deregistration
and target_failover.on_unhealthy ) can't be set independently. The value you
set for both attributes must be the same.
target_failover.on_unhealthy - Indicates how the Gateway Load Balancer handles
existing flows when a target is unhealthy. The possible values are rebalance
and no_rebalance . The default is no_rebalance . The two attributes (target_failover.on_deregistration
and target_failover.on_unhealthy ) cannot be set independently. The value you
set for both attributes must be the same.
