Parameters:

scope (Construct) – Scope in which this resource is defined.
id (str) – Construct identifier for this resource (unique in its scope).
listeners (Union[IResolvable, Sequence[Union[IResolvable, ListenersProperty, Dict[str, Any]]]]) – The listeners for the load balancer. You can specify at most one listener per port. If you update the properties for a listener, AWS CloudFormation deletes the existing listener and creates a new one with the specified properties. While the new listener is being created, clients cannot connect to the load balancer.
access_logging_policy (Union[IResolvable, AccessLoggingPolicyProperty, Dict[str, Any], None]) – Information about where and how access logs are stored for the load balancer.
app_cookie_stickiness_policy (Union[IResolvable, Sequence[Union[IResolvable, AppCookieStickinessPolicyProperty, Dict[str, Any]]], None]) – Information about a policy for application-controlled session stickiness.
availability_zones (Optional[Sequence[str]]) – The Availability Zones for a load balancer in a default VPC. For a load balancer in a nondefault VPC, specify Subnets instead. Update requires replacement if you did not previously specify an Availability Zone or if you are removing all Availability Zones. Otherwise, update requires no interruption.
connection_draining_policy (Union[IResolvable, ConnectionDrainingPolicyProperty, Dict[str, Any], None]) – If enabled, the load balancer allows existing requests to complete before the load balancer shifts traffic away from a deregistered or unhealthy instance. For more information, see Configure connection draining in the User Guide for Classic Load Balancers .
connection_settings (Union[IResolvable, ConnectionSettingsProperty, Dict[str, Any], None]) – If enabled, the load balancer allows the connections to remain idle (no data is sent over the connection) for the specified duration. By default, Elastic Load Balancing maintains a 60-second idle connection timeout for both front-end and back-end connections of your load balancer. For more information, see Configure idle connection timeout in the User Guide for Classic Load Balancers .
cross_zone (Union[bool, IResolvable, None]) – If enabled, the load balancer routes the request traffic evenly across all instances regardless of the Availability Zones. For more information, see Configure cross-zone load balancing in the User Guide for Classic Load Balancers .
health_check (Union[IResolvable, HealthCheckProperty, Dict[str, Any], None]) – The health check settings to use when evaluating the health of your EC2 instances. Update requires replacement if you did not previously specify health check settings or if you are removing the health check settings. Otherwise, update requires no interruption.
instances (Optional[Sequence[str]]) – The IDs of the instances for the load balancer.
lb_cookie_stickiness_policy (Union[IResolvable, Sequence[Union[IResolvable, LBCookieStickinessPolicyProperty, Dict[str, Any]]], None]) – Information about a policy for duration-based session stickiness.
load_balancer_name (Optional[str]) – The name of the load balancer. This name must be unique within your set of load balancers for the region. If you don’t specify a name, AWS CloudFormation generates a unique physical ID for the load balancer. For more information, see Name Type . If you specify a name, you cannot perform updates that require replacement of this resource, but you can perform other updates. To replace the resource, specify a new name.
policies (Union[IResolvable, Sequence[Union[IResolvable, PoliciesProperty, Dict[str, Any]]], None]) – The policies defined for your Classic Load Balancer. Specify only back-end server policies.
scheme (Optional[str]) – The type of load balancer. Valid only for load balancers in a VPC. If Scheme is internet-facing , the load balancer has a public DNS name that resolves to a public IP address. If Scheme is internal , the load balancer has a public DNS name that resolves to a private IP address.
security_groups (Optional[Sequence[str]]) – The security groups for the load balancer. Valid only for load balancers in a VPC.
subnets (Optional[Sequence[str]]) – The IDs of the subnets for the load balancer. You can specify at most one subnet per Availability Zone. Update requires replacement if you did not previously specify a subnet or if you are removing all subnets. Otherwise, update requires no interruption. To update to a different subnet in the current Availability Zone, you must first update to a subnet in a different Availability Zone, then update to the new subnet in the original Availability Zone.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The tags associated with a load balancer.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_dependency(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_depends_on(target)

(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

Return type:

None

get_att(attribute_name, type_hint=None)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:

attribute_name (str) – The name of the attribute.
type_hint (Optional[ResolutionTypeHint]) –

Return type:

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

interval (str) – The approximate interval, in seconds, between health checks of an individual instance.
target (str) – The instance being checked. The protocol is either TCP, HTTP, HTTPS, or SSL. The range of valid ports is one (1) through 65535. TCP is the default, specified as a TCP: port pair, for example “TCP:5000”. In this case, a health check simply attempts to open a TCP connection to the instance on the specified port. Failure to connect within the configured timeout is considered unhealthy. SSL is also specified as SSL: port pair, for example, SSL:5000. For HTTP/HTTPS, you must include a ping path in the string. HTTP is specified as a HTTP:port;/;PathToPing; grouping, for example “HTTP:80/weather/us/wa/seattle”. In this case, a HTTP GET request is issued to the instance on the given port and path. Any answer other than “200 OK” within the timeout period is considered unhealthy. The total length of the HTTP ping target must be 1024 16-bit Unicode characters or less.
timeout (str) – The amount of time, in seconds, during which no response means a failed health check. This value must be less than the Interval value.
unhealthy_threshold (str) – The number of consecutive health check failures required before moving the instance to the Unhealthy state.

SSL is also specified as SSL: port pair, for example, SSL:5000.

For HTTP/HTTPS, you must include a ping path in the string. HTTP is specified as a HTTP:port;/;PathToPing; grouping, for example “HTTP:80/weather/us/wa/seattle”. In this case, a HTTP GET request is issued to the instance on the given port and path. Any answer other than “200 OK” within the timeout period is considered unhealthy.

The total length of the HTTP ping target must be 1024 16-bit Unicode characters or less.

See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-elasticloadbalancing-loadbalancer-healthcheck.html#cfn-elasticloadbalancing-loadbalancer-healthcheck-target

timeout

The amount of time, in seconds, during which no response means a failed health check.

This value must be less than the Interval value.

See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-elasticloadbalancing-loadbalancer-healthcheck.html#cfn-elasticloadbalancing-loadbalancer-healthcheck-timeout

unhealthy_threshold

The number of consecutive health check failures required before moving the instance to the Unhealthy state.

LBCookieStickinessPolicyProperty

class CfnLoadBalancer.LBCookieStickinessPolicyProperty(*, cookie_expiration_period=None, policy_name=None)

Bases: object

Specifies a policy for duration-based session stickiness for your Classic Load Balancer.

To associate a policy with a listener, use the PolicyNames property for the listener.

Parameters:

cookie_expiration_period (Optional[str]) – The time period, in seconds, after which the cookie should be considered stale. If this parameter is not specified, the stickiness session lasts for the duration of the browser session.
policy_name (Optional[str]) – The name of the policy. This name must be unique within the set of policies for this load balancer.

Attributes

cookie_expiration_period

The time period, in seconds, after which the cookie should be considered stale.

If this parameter is not specified, the stickiness session lasts for the duration of the browser session.

See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-elasticloadbalancing-loadbalancer-lbcookiestickinesspolicy.html#cfn-elasticloadbalancing-loadbalancer-lbcookiestickinesspolicy-cookieexpirationperiod

policy_name

ListenersProperty

class CfnLoadBalancer.ListenersProperty(*, instance_port, load_balancer_port, protocol, instance_protocol=None, policy_names=None, ssl_certificate_id=None)

Bases: object

Specifies a listener for your Classic Load Balancer.

Modifying any property replaces the listener.

Parameters:

instance_port (str) – The port on which the instance is listening.
load_balancer_port (str) – The port on which the load balancer is listening. On EC2-VPC, you can specify any port from the range 1-65535. On EC2-Classic, you can specify any port from the following list: 25, 80, 443, 465, 587, 1024-65535.
protocol (str) – The load balancer transport protocol to use for routing: HTTP, HTTPS, TCP, or SSL.
instance_protocol (Optional[str]) – The protocol to use for routing traffic to instances: HTTP, HTTPS, TCP, or SSL. If the front-end protocol is TCP or SSL, the back-end protocol must be TCP or SSL. If the front-end protocol is HTTP or HTTPS, the back-end protocol must be HTTP or HTTPS. If there is another listener with the same InstancePort whose InstanceProtocol is secure, (HTTPS or SSL), the listener’s InstanceProtocol must also be secure. If there is another listener with the same InstancePort whose InstanceProtocol is HTTP or TCP, the listener’s InstanceProtocol must be HTTP or TCP.
policy_names (Optional[Sequence[str]]) – The names of the policies to associate with the listener.
ssl_certificate_id (Optional[str]) – The Amazon Resource Name (ARN) of the server certificate.
