MasterSlaveServerGroup

• Implements: IMasterSlaveServerGroup

This class encapsulates and extends the ROS resource type ALIYUN::SLB::MasterSlaveServerGroup, which is used to create a primary/secondary server group.

Initializers

import com.aliyun.ros.cdk.slb.MasterSlaveServerGroup;
MasterSlaveServerGroup.Builder.create(Construct scope, java.lang.String id, java.lang.Boolean enableResourcePropertyConstraint)
    .loadBalancerId(java.lang.String)
    .loadBalancerId(IResolvable)
    .masterSlaveBackendServers(IResolvable)
    .masterSlaveBackendServers(java.util.List<IResolvable)
    .masterSlaveBackendServers(MasterSlaveBackendServersProperty>)
//  .masterSlaveServerGroupName(java.lang.String)
//  .masterSlaveServerGroupName(IResolvable)
    .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 the Server Load Balancer instance.

masterSlaveBackendServers^Required

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

Property masterSlaveBackendServers: The backend servers in the primary\/secondary server group.

Each primary/secondary server group consists of two backend servers. Configure the following parameters:

• ServerId: required. The IDs of the backend servers. Specify the IDs in a string. You can specify the IDs of Elastic Compute Service (ECS) instances, elastic network interfaces (ENIs), and elastic container instances. If you set ServerId to the IDs of ENIs or elastic container instances, 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 servers. 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
• eci: elastic container instance

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

• ServerIp: the IP address of the ENI or elastic container instance.
• Port: the backend port.
• ServerType: Specify the primary and secondary backend servers in a string. Valid values:
• Master: primary server
• Slave: secondary server

masterSlaveServerGroupName^Optional

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

Property masterSlaveServerGroupName: The name of the active\/standby 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.slb.MasterSlaveServerGroup;
MasterSlaveServerGroup.isConstruct(java.lang.Object x)

Return whether the given object is a Construct.

x^Required

• Type: java.lang.Object

Properties

node^Required

public ConstructNode getNode();

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

The construct tree node associated with this construct.

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.

ref^Required

public java.lang.String getRef();

• Type: java.lang.String

stack^Required

public Stack getStack();

• Type: com.aliyun.ros.cdk.core.Stack

The stack in which this resource is defined.

resource^Optional

public RosResource getResource();

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

attrMasterSlaveServerGroupId^Required

public java.lang.Object getAttrMasterSlaveServerGroupId();

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

Attribute MasterSlaveServerGroupId: Active/standby server group ID.

props^Required

public MasterSlaveServerGroupProps getProps();

• Type: MasterSlaveServerGroupProps
