VServerGroup

• Implements: IVServerGroup

This class encapsulates and extends the ROS resource type ALIYUN::SLB::VServerGroup, which is used to create a server group and attach backend servers to a Server Load Balancer (SLB) instance.

Initializers

import com.aliyun.ros.cdk.slb.VServerGroup;
VServerGroup.Builder.create(Construct scope, java.lang.String id, java.lang.Boolean enableResourcePropertyConstraint)
    .loadBalancerId(java.lang.String)
    .loadBalancerId(IResolvable)
    .vServerGroupName(java.lang.String)
    .vServerGroupName(IResolvable)
//  .backendServers(IResolvable)
//  .backendServers(java.util.List<IResolvable)
//  .backendServers(BackendServersProperty>)
//  .tags(java.util.List<TagsProperty>)
    .build();

scope^Required

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

id^Required

• Type: java.lang.String

enableResourcePropertyConstraint^Optional

• Type: java.lang.Boolean

loadBalancerId^Required

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

Property loadBalancerId: The id of load balancer.

vServerGroupName^Required

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

Property vServerGroupName: The name of the vServer group.

The name must be 1 to 80 characters in length, and can contain letters, digits, hyphens (-), forward slashes (/), periods (.),and underscores (_).

backendServers^Optional

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

Property backendServers: The backend servers that you want to add.

Configure the following parameters:

• ServerId: required. The ID of the backend server. Specify the ID in a string. You can specify the ID of an Elastic Compute Service (ECS) instance, an elastic network interface (ENI), or an elastic container instance. If you set ServerId to the ID of an ENI or an elastic container instance, you must configure the Type parameter.
• Weight: the weight of the backend server. Valid values: 0 to 100. Default value: 100. If you set the weight of a backend server to 0, no requests are forwarded to the backend server.
• Description: optional. The description of the backend server. Specify the description in a string. The description must be 1 to 80 characters in length, and can contain letters, digits, hyphens (-), forward slashes (/), periods (.), and underscores (_).
• Type: the type of the backend server. Valid values:
• ecs (default): ECS instance
• eni: ENI.
• eni: elastic container instance.

You can specify ENIs and elastic container instances as backend servers only for high-performance SLB instances.

• ServerIp: The IP address of the ECS instance or ENI.
• Port: the backend port. Examples:
• Add an ECS instance: [{ "ServerId": "i-xxxxxxxxx", "Weight": "100", "Type": "ecs", "Port":"80","Description":"test-112" }]
• Add an ENI: [{ "ServerId": "eni-xxxxxxxxx", "Weight": "100", "Type": "eni", "ServerIp": "192.168..", "Port":"80","Description":"test-112" }]
• Add an ENI with multiple IP addresses: [{ "ServerId": "eni-xxxxxxxxx", "Weight": "100", "Type": "eni", "ServerIp": "192.168..", "Port":"80","Description":"test-113" },{ "ServerId": "eni-xxxxxxxxx", "Weight": "100", "Type": "eni", "ServerIp": "172.166..", "Port":"80","Description":"test-113" }]
• Add an elastic container instance: [{ "ServerId": "eci-xxxxxxxxx", "Weight": "100", "Type": "eci", "ServerIp": "192.168..", "Port":"80","Description":"test-114" }]

You can add only running backend servers to SLB instances. You can specify at most 20 backend servers.

tags^Optional

• Type: java.util.List<TagsProperty>

Property tags: Tags to attach to instance.

Max support 20 tags to add during create instance. Each tag with two properties Key and Value, and Key is required.

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
