Property connectionDrainConfig: Connected graceful interrupt configuration.

healthCheckConfig^Optional

• Type: com.aliyun.ros.cdk.core.IResolvable OR HealthCheckConfigProperty

scheduler^Optional

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property scheduler: Scheduling algorithm.

Value:

• 5TCH (default): quintuple hash, which is based on the consistent hash of the quintuple (source IP, Destination IP, source port, destination port, and protocol). The same flow is scheduled to the same backend server.
• 3TCH: a three-tuple hash, which is based on the consistent hash of three tuples (source IP address, destination IP address, and protocol). The same flow is dispatched to the same backend server.
• 2TCH: Binary Group hash, which is based on the consistent hash of the binary group (source IP and destination IP). The same flow is scheduled to the same backend server.

serverGroupName^Optional

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property serverGroupName: The server group name.

It must be 2 to 128 characters in length, start with an uppercase letter or a Chinese character, and can contain digits, half-width periods (.), underscores (_), and dashes (-).

serverGroupType^Optional

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property serverGroupType: The server group type.

Value:

• Instance (default): The instance type. You can add Ecs, Eni, and Eci instances to the server group.
• Ip: The Ip address type. You can directly add backend servers of the Ip address type to the server group.

servers^Optional

• Type: com.aliyun.ros.cdk.core.IResolvable OR java.util.ListServersProperty>

Property servers: List of servers.

tags^Optional

• Type: java.util.List<TagsProperty>

Property tags: Tags of server group.

Methods

toString

public java.lang.String toString()

Returns a string representation of this construct.

synthesize

public void synthesize(ISynthesisSession session)

Allows this construct to emit artifacts into the cloud assembly during synthesis.

This method is usually implemented by framework-level constructs such as Stack and Asset as they participate in synthesizing the cloud assembly.

session^Required

• Type: com.aliyun.ros.cdk.core.ISynthesisSession

The synthesis session.

addCondition

public void addCondition(RosCondition condition)

condition^Required

• Type: com.aliyun.ros.cdk.core.RosCondition

addCount

public void addCount(java.lang.Number OR IResolvable count)

count^Required

• Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable

addDependency

public void addDependency(Resource resource)

resource^Required

• Type: com.aliyun.ros.cdk.core.Resource

addResourceDesc

public void addResourceDesc(java.lang.String desc)

desc^Required

• Type: java.lang.String

applyRemovalPolicy

public void applyRemovalPolicy(RemovalPolicy policy)

policy^Required

• Type: com.aliyun.ros.cdk.core.RemovalPolicy

fetchCondition

public RosCondition fetchCondition()

fetchDependency

public java.util.List<java.lang.String> fetchDependency()

fetchResourceDesc

public java.lang.String fetchResourceDesc()

getAtt

public IResolvable getAtt(java.lang.String name)

name^Required

• Type: java.lang.String

setMetadata

public void setMetadata(java.lang.String key, java.lang.Object value)

key^Required

• Type: java.lang.String

value^Required

• Type: java.lang.Object

Static Functions

isConstruct

import com.aliyun.ros.cdk.gwlb.ServerGroup;
ServerGroup.isConstruct(java.lang.Object x)

Return whether the given object is a Construct.

x^Required

• Type: java.lang.Object

env^Required

public IResourceEnvironment getEnv();

• Type: com.aliyun.ros.cdk.core.IResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

The stack in which this resource is defined.
