AWS::EKS::FargateProfile - AWS CloudFormation

AWS::EKS::FargateProfile

Creates an AWS Fargate profile for your Amazon EKS cluster. You must have at least one Fargate profile in a cluster to be able to run pods on Fargate.

The Fargate profile allows an administrator to declare which pods run on Fargate and specify which pods run on which Fargate profile. This declaration is done through the profile’s selectors. Each profile can have up to five selectors that contain a namespace and labels. A namespace is required for every selector. The label field consists of multiple optional key-value pairs. Pods that match the selectors are scheduled on Fargate. If a to-be-scheduled pod matches any of the selectors in the Fargate profile, then that pod is run on Fargate.

When you create a Fargate profile, you must specify a pod execution role to use with the pods that are scheduled with the profile. This role is added to the cluster's Kubernetes Role Based Access Control (RBAC) for authorization so that the kubelet that is running on the Fargate infrastructure can register with your Amazon EKS cluster so that it can appear in your cluster as a node. The pod execution role also provides IAM permissions to the Fargate infrastructure to allow read access to Amazon ECR image repositories. For more information, see Pod Execution Role in the Amazon EKS User Guide.

Fargate profiles are immutable. However, you can create a new updated profile to replace an existing profile and then delete the original after the updated profile has finished creating.

If any Fargate profiles in a cluster are in the DELETING status, you must wait for that Fargate profile to finish deleting before you can create any other profiles in that cluster.

For more information, see AWS Fargate Profile in the Amazon EKS User Guide.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{ "Type" : "AWS::EKS::FargateProfile", "Properties" : { "ClusterName" : String, "FargateProfileName" : String, "PodExecutionRoleArn" : String, "Selectors" : [ Selector, ... ], "Subnets" : [ String, ... ], "Tags" : [ Tag, ... ] } }

YAML

Type: AWS::EKS::FargateProfile Properties: ClusterName: String FargateProfileName: String PodExecutionRoleArn: String Selectors: - Selector Subnets: - String Tags: - Tag

Properties

ClusterName

The name of the Amazon EKS cluster to apply the Fargate profile to.

Required: Yes

Type: String

Update requires: Replacement

FargateProfileName

The name of the Fargate profile.

Required: No

Type: String

Update requires: Replacement

PodExecutionRoleArn

The Amazon Resource Name (ARN) of the pod execution role to use for pods that match the selectors in the Fargate profile. The pod execution role allows Fargate infrastructure to register with your cluster as a node, and it provides read access to Amazon ECR image repositories. For more information, see Pod Execution Role in the Amazon EKS User Guide.

Required: Yes

Type: String

Update requires: Replacement

Selectors

The selectors to match for pods to use this Fargate profile. Each selector must have an associated namespace. Optionally, you can also specify labels for a namespace. You may specify up to five selectors in a Fargate profile.

Required: Yes

Type: List of Selector

Update requires: Replacement

Subnets

The IDs of subnets to launch your pods into. At this time, pods running on Fargate are not assigned public IP addresses, so only private subnets (with no direct route to an Internet Gateway) are accepted for this parameter.

Required: No

Type: List of String

Update requires: Replacement

Tags

The metadata to apply to the Fargate profile to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Fargate profile tags do not propagate to any other resources associated with the Fargate profile, such as the pods that are scheduled with it.

Required: No

Type: List of Tag

Update requires: No interruption

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the resource name. For example:

{ "Ref": "myFargateProfile" }

For the Fargate profilemyFargateProfile, Ref returns the physical resource ID of the Fargate profile. For example, <cluster_name>/<Fargate_profile_name>.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Arn

The ARN of the cluster, such as arn:aws:eks:us-west-2:666666666666:fargateprofile/myCluster/myFargateProfile/1cb1a11a-1dc1-1d11-cf11-1111f11fa111.
