Question

Kubernetes create a load balancer, for each service; automatically in GCE. How can I manage something similar on AWS?

Kubernetes service basically use the kubeproxy

Answer 1

Minimal example:

kind: Service
apiVersion: v1
metadata:
  name: my-service
spec:
  type: LoadBalancer
  selector:
    app: MyApp
  ports:
  - protocol: TCP
    port: 80
    targetPort: 9376

The relevant docs:

• Create an External Load Balancer
• Type LoadBalancer

As of writing the best way to learn about all the service.beta.kubernetes.io annotations is to read the source code:

• cloudprovider/providers/aws/aws.go

For the controller to be able to manage the ELB it will need permissions set in the master instances IAM Role, e.g.:

...
{
  "Action": "elasticloadbalancing:*",
  "Resource": "*",
  "Effect": "Allow"
},
{
  "Action": [
    "ecr:GetAuthorizationToken",
    "ecr:BatchCheckLayerAvailability",
    "ecr:GetDownloadUrlForLayer",
    "ecr:GetRepositoryPolicy",
    "ecr:DescribeRepositories",
    "ecr:ListImages",
    "ecr:BatchGetImage"
  ],
  "Resource": "*",
  "Effect": "Allow"
},
...

The cloud provider should be set with --cloud-provider=aws on kube-apiserver.
