Gardener Extension for AWS provider
Project Gardener implements the automated management and operation of Kubernetes clusters as a service. Its main principle is to leverage Kubernetes concepts for all of its tasks.
Recently, most of the vendor specific logic has been developed in-tree. However, the project has grown to a size where it is very hard to extend, maintain, and test. With GEP-1 we have proposed how the architecture can be changed in a way to support external controllers that contain their very own vendor specifics. This way, we can keep Gardener core clean and independent.
This controller operates on the Infrastructure resource in the extensions.gardener.cloud/v1alpha1 API group. It manages those objects that are requesting an AWS infrastructure (.spec.type=aws):
---
apiVersion: extensions.gardener.cloud/v1alpha1
kind: Infrastructure
metadata:
name: infrastructure
spec:
type: aws
region: eu-west-1
secretRef:
name: cloudprovider
namespace: shoot--foobar--aws
providerConfig:
apiVersion: aws.provider.extensions.gardener.cloud/v1alpha1
kind: InfrastructureConfig
networks:
vpc: # specify either 'id' or 'cidr'
# id: vpc-123456
cidr: 10.250.0.0/16
zones:
- name: eu-west-1a
internal: 10.250.112.0/22
public: 10.250.96.0/22
workers: 10.250.0.0/19
sshPublicKey: ...
Please find a concrete example in the example folder.
After reconciliation the resulting data will be stored in the resource's .status field:
...
status:
...
providerStatus:
apiVersion: aws.provider.extensions.gardener.cloud/v1alpha1
kind: InfrastructureStatus
...
An example for a ControllerRegistration resource that can be used to register this controller to Gardener can be found here.
Please find more information regarding the extensibility concepts and a detailed proposal here.
How to start using or developing this extension controller locally
You can run the controller locally on your machine by executing make start-provider-aws.
Static code checks and tests can be executed by running VERIFY=true make all. We are using dep for Golang package dependency management and Ginkgo/Gomega for testing.
