## Request Parameters
<a name="API_UpdateContainerAssociation_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [ContainerAssociationArn](#API_UpdateContainerAssociation_RequestSyntax) **   <a name="networkfirewall-UpdateContainerAssociation-request-ContainerAssociationArn"></a>
The Amazon Resource Name (ARN) of the container association.  
You must specify the ARN or the name, and you can specify both.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `^arn:aws.*`   
Required: No

 ** [ContainerAssociationName](#API_UpdateContainerAssociation_RequestSyntax) **   <a name="networkfirewall-UpdateContainerAssociation-request-ContainerAssociationName"></a>
The descriptive name of the container association.  
You must specify the ARN or the name, and you can specify both.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 128.  
Pattern: `^[a-zA-Z0-9-]+$`   
Required: No

 ** [ContainerMonitoringConfigurations](#API_UpdateContainerAssociation_RequestSyntax) **   <a name="networkfirewall-UpdateContainerAssociation-request-ContainerMonitoringConfigurations"></a>
The updated monitoring configurations for the container association. Each configuration specifies an Amazon ECS or Amazon EKS cluster to monitor and optional attribute filters.  
Type: Array of [ContainerMonitoringConfiguration](API_ContainerMonitoringConfiguration.md) objects  
Required: Yes

 ** [Description](#API_UpdateContainerAssociation_RequestSyntax) **   <a name="networkfirewall-UpdateContainerAssociation-request-Description"></a>
A description of the container association. When omitted, the existing description remains unchanged. To clear the description, pass an empty string.  
Type: String  
Length Constraints: Maximum length of 512.  
Pattern: `^.*$`   
Required: No

 ** [Tags](#API_UpdateContainerAssociation_RequestSyntax) **   <a name="networkfirewall-UpdateContainerAssociation-request-Tags"></a>
The key:value pairs to associate with the resource.  
Type: Array of [Tag](API_Tag.md) objects  
Array Members: Minimum number of 1 item. Maximum number of 200 items.  
Required: No

 ** [Type](#API_UpdateContainerAssociation_RequestSyntax) **   <a name="networkfirewall-UpdateContainerAssociation-request-Type"></a>
The container type. This value must match the existing type and can't be changed. Valid values:  
+  `ECS` - Amazon Elastic Container Service
+  `EKS` - Amazon Elastic Kubernetes Service
Type: String  
Valid Values: `ECS | EKS`   
Required: Yes

 ** [UpdateToken](#API_UpdateContainerAssociation_RequestSyntax) **   <a name="networkfirewall-UpdateContainerAssociation-request-UpdateToken"></a>
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 changes to the container association, you provide the token in your request. Network Firewall uses the token to ensure that the container association hasn't changed since you last retrieved it. If it has changed, the operation fails with an `InvalidTokenException`. If this happens, retrieve the container association again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 1024.  
Pattern: `^([0-9a-f]{8})-([0-9a-f]{4}-){3}([0-9a-f]{12})$`   
Required: Yes
