CfnFlow¶

class aws_cdk.aws_mediaconnect.CfnFlow(scope, id, *, name, source, availability_zone=None, source_failover_config=None)¶

Bases: aws_cdk.core.CfnResource

A CloudFormation AWS::MediaConnect::Flow.

The AWS::MediaConnect::Flow resource defines a connection between one or more video sources and one or more outputs. For each flow, you specify the transport protocol to use, encryption information, and details for any outputs or entitlements that you want. AWS Elemental MediaConnect returns an ingest endpoint where you can send your live video as a single unicast stream. The service replicates and distributes the video to every output that you specify, whether inside or outside the AWS Cloud. You can also set up entitlements on a flow to allow other AWS accounts to access your content.

Create a new AWS::MediaConnect::Flow.

Parameters

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
name (str) – The name of the flow.
source (Union[SourceProperty, IResolvable]) – The settings for the source that you want to use for the new flow.
availability_zone (Optional[str]) – The Availability Zone that you want to create the flow in. These options are limited to the Availability Zones within the current AWS Region.
source_failover_config (Union[IResolvable, FailoverConfigProperty, None]) – The settings for source failover.

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_depends_on(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_metadata(key, value)¶

Add a value to the CloudFormation Resource Metadata.

Parameters

key (str) –
value (Any) –

See

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.

Return type: None

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 intermdediate 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).

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 resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)¶

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.
Return type: Reference

get_metadata(key)¶

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

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.

Return type: Any

inspect(inspector)¶

Examines the CloudFormation resource and discloses attributes.

Parameters

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Bases: object

The details of the sources of the flow.

If you are creating a flow with a VPC source, you must first create the flow with a temporary standard source by doing the following:

Use CloudFormation to create a flow with a standard source that uses the flow’s public IP address.
Use CloudFormation to create the VPC interface to add to this flow. This can also be done as part of the previous step.
After CloudFormation has created the flow and the VPC interface, update the source to point to the VPC interface that you created.

Parameters

decryption (Union[IResolvable, EncryptionProperty, None]) – The type of encryption that is used on the content ingested from the source.
description (Optional[str]) – A description of the source. This description is not visible outside of the current AWS account.
entitlement_arn (Optional[str]) – The ARN of the entitlement that allows you to subscribe to content that comes from another AWS account. The entitlement is set by the content originator and the ARN is generated as part of the originator’s flow.
ingest_ip (Optional[str]) – The IP address that the flow listens on for incoming content.
ingest_port (Union[int, float, None]) – The port that the flow listens on for incoming content. If the protocol of the source is Zixi, the port must be set to 2088.
