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 ros_cdk_slb
ros_cdk_slb.MasterSlaveServerGroup(
  scope: Construct,
  id: str,
  load_balancer_id: typing.Union[str, IResolvable],
  master_slave_backend_servers: typing.Union[IResolvable, typing.List[typing.Union[IResolvable, MasterSlaveBackendServersProperty]]],
  master_slave_server_group_name: typing.Union[str, IResolvable] = None,
  enable_resource_property_constraint: bool = None
)

scope^Required

• Type: ros_cdk_core.Construct

id^Required

• Type: str

load_balancer_id^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property loadBalancerId: The ID of the Server Load Balancer instance.

master_slave_backend_servers^Required

• Type: typing.Union[ros_cdk_core.IResolvable, typing.List[typing.Union[ros_cdk_core.IResolvable, MasterSlaveBackendServersProperty]]]

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

master_slave_server_group_name^Optional

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property masterSlaveServerGroupName: The name of the active\/standby server group.

enable_resource_property_constraint^Optional

• Type: bool

Methods

to_string

def to_string() -> str

Returns a string representation of this construct.

synthesize

def synthesize(
  session: ISynthesisSession
) -> None

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: ros_cdk_core.ISynthesisSession

The synthesis session.

add_condition

def add_condition(
  condition: RosCondition
) -> None

condition^Required

• Type: ros_cdk_core.RosCondition

add_count

def add_count(
  count: typing.Union[typing.Union[int, float], IResolvable]
) -> None

count^Required

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

add_dependency

def add_dependency(
  resource: Resource
) -> None

resource^Required

• Type: ros_cdk_core.Resource

add_resource_desc

def add_resource_desc(
  desc: str
) -> None

desc^Required

• Type: str

apply_removal_policy

def apply_removal_policy(
  policy: RemovalPolicy
) -> None

policy^Required

• Type: ros_cdk_core.RemovalPolicy

fetch_condition

def fetch_condition() -> RosCondition

fetch_dependency

def fetch_dependency() -> typing.List[str]

fetch_resource_desc

def fetch_resource_desc() -> str

get_att

def get_att(
  name: str
) -> IResolvable

name^Required

• Type: str

set_metadata

def set_metadata(
  key: str,
  value: typing.Any
) -> None

key^Required

• Type: str

value^Required

• Type: typing.Any

Static Functions

is_construct

import ros_cdk_slb
ros_cdk_slb.MasterSlaveServerGroup.is_construct(
  x: typing.Any
)

Return whether the given object is a Construct.

x^Required

• Type: typing.Any

Properties

node^Required

node: ConstructNode

• Type: ros_cdk_core.ConstructNode

The construct tree node associated with this construct.

env^Required

env: IResourceEnvironment

• Type: 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

ref: str

• Type: str

stack^Required

stack: Stack

• Type: ros_cdk_core.Stack

The stack in which this resource is defined.

resource^Optional

resource: RosResource

• Type: ros_cdk_core.RosResource

attr_master_slave_server_group_id^Required

attr_master_slave_server_group_id: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Attribute MasterSlaveServerGroupId: Active/standby server group ID.

props^Required

props: MasterSlaveServerGroupProps

• Type: MasterSlaveServerGroupProps
