2026/06/30 - AWS Network Firewall - 5 new api methods
Changes AWS Network Firewall now supports container associations for monitoring ECS and EKS workloads. You can create container associations to dynamically track the IP addresses of running containers in your Amazon ECS and Amazon EKS clusters.
Retrieves the metadata for the container associations that you have defined. You can optionally page through results.

Request Syntax
client.list_container_associations(
MaxResults=123,
NextToken='string'
)
integer
The maximum number of objects that you want Network Firewall to return for this request. If more objects are available, in the response, Network Firewall provides a NextToken value that you can use in a subsequent call to get the next batch of objects.
string
When you request a list of objects with a MaxResults setting, if the number of objects that are still available for retrieval exceeds the maximum you requested, Network Firewall returns a NextToken value in the response. To retrieve the next batch of objects, use the token returned from the prior request in your next request.

Response Structure
(dict) --
ContainerAssociations (list) --
The container association metadata objects.
(dict) --
High-level information about a container association, returned by the ListContainerAssociations operation. You can use this information to retrieve the full details of a container association using DescribeContainerAssociation.
Arn (string) --
The Amazon Resource Name (ARN) of the container association.
Name (string) --
The descriptive name of the container association.
NextToken (string) --
When you request a list of objects with a MaxResults setting, if the number of objects that are still available for retrieval exceeds the maximum you requested, Network Firewall returns a NextToken value in the response. To retrieve the next batch of objects, use the token returned from the prior request in your next request.
Deletes the specified container association. When you delete a container association, Network Firewall stops monitoring the associated container clusters and removes the resolved IP addresses from firewall rules.

[REQUIRED]
A token used for optimistic locking. Network Firewall returns a token to your requests that access the container association. The token marks the state of the container association resource at the time of the request. To make an update to the container association, provide the token in your request.

If this happens, retrieve the container association again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.

Creates a container association for Network Firewall. A container association links container clusters (ECS or EKS) to Network Firewall, enabling dynamic IP resolution for firewall rules based on container attributes.
To manage a container association's tags, use the standard Amazon Web Services resource tagging operations, ListTagsForResource, TagResource, and UntagResource.
To retrieve information about container associations, use ListContainerAssociations and DescribeContainerAssociation.
