⁠Cloud Assistant

Phoenix application that implements Cloud Assistant Alexa Skill beta to interact with Kubernetes Clusters.

To use this assistant, you have to deploy it in a kubernetes cluster and expose as a service. The cluster must be added to DynamoDB ClusterPermissions table associated to the user_id that will be used to trigger the skill.

In the following actions, there are examples to deploy, expose and authorize Cloud Assistant in Kubernetes Cluster.

To deploy Cloud Assistant, apply the file below and change as needed.

$ kubectl apply -f kubernetes/cloud-assistant.deployment.yaml

apiVersion: extensions/v1beta1
