aws-iam interface

This interface provides communication between kubernetes-control-plane and aws-iam subordinate.

It allows the requires side, aws-iam, to know when the api server is up and available and to tell the api server when the webhook.yaml file is written so that it may restart and use the webhook.

Provides (kubernetes-control-plane side)

States

• aws-iam.available Indicates that there are one or more units on the other side of the relation
• aws-iam.ready Indicates that the webhook status has been set. This is used to indicate it is time to restart the API server to pick up the webhook config on the Kubernetes side.

Methods

• get_cluster_id The AWS-IAM charm generates a random cluster ID for the cluster that is needed in the kubectl configuration file. This is retrieved from the relation here.
• set_api_server_status This is set to indicate if the Kubernetes API server is up and ready for connections. This is needed because the aws-iam charm needs to set up the service it will use in order to add the IP to the extra sans in the ssl certificate used to secure communication between the control-plane and the service.

Requires (aws-iam side)

States

Methods
