Amazon Elastic Kubernetes Service

2019/12/03 - Amazon Elastic Kubernetes Service - 4 new api methods

Changes  Introducing Amazon EKS with Fargate. Customers can now use Amazon EKS to launch pods directly onto AWS Fargate, the serverless compute engine built for containers on AWS.

CreateFargateProfile (new) Link ¶

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 schedule pods on Fargate infrastructure.

The Fargate profile allows an administrator to declare which pods run on Fargate infrastructure 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 infrastructure. If a to-be-scheduled pod matches any of the selectors in the Fargate profile, then that pod is scheduled on Fargate infrastructure.

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. This role is what allows Fargate infrastructure to appear in your cluster as nodes. 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 .

    • namespace (string) --

      The Kubernetes namespace that the selector should match.

DeleteFargateProfile (new) Link ¶

Deletes an AWS Fargate profile.

When you delete a Fargate profile, any pods that were scheduled onto Fargate infrastructure with the profile are deleted. If those pods match another Fargate profile, then they are scheduled on Fargate infrastructure with that profile. If they no longer match any Fargate profiles, then they are not scheduled on Fargate infrastructure.

Only one Fargate profile in a cluster can be in the DELETING status at a time. You must wait for a Fargate profile to finish deleting before you can delete any other profiles in that cluster.
