// Creates an 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 (https://kubernetes.io/docs/admin/authorization/rbac/)
// (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 (https://docs.aws.amazon.com/eks/latest/userguide/pod-execution-role.html)
// 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 Fargate Profile (https://docs.aws.amazon.com/eks/latest/userguide/fargate-profile.html)
// in the Amazon EKS User Guide.
