controller

Infra controller, apply any infra resource your want.

Getting Started

You’ll need a Kubernetes cluster to run against. You can use KIND to get a local cluster for testing, or run against a remote cluster. Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info shows).

Running on the cluster
  1. Install Instances of Custom Resources:
kubectl apply -f config/samples/
  1. Build and push your image to the location specified by IMG:
make docker-build docker-push IMG=<some-registry>/controller:tag
  1. Deploy the controller to the cluster with the image specified by IMG:
make deploy IMG=<some-registry>/controller:tag
Uninstall CRDs

To delete the CRDs from the cluster:

make uninstall
Undeploy controller

UnDeploy the controller to the cluster:

make undeploy
How it works

This project aims to follow the Kubernetes Operator pattern

It uses Controllers which provides a reconcile function responsible for synchronizing resources untile the desired state is reached on the cluster

Test It Out
  1. Install the CRDs into the cluster:
make install
  1. Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):
make run

NOTE: You can also run this in one step by running: make install run

Modifying the API definitions

If you are editing the API definitions, generate the manifests such as CRs or CRDs using:

make manifests
Infra AMI configmap

Expose the virtual machine image id to all users,read-only.

NOTE: Run make --help for more information on all potential make targets

More information can be found via the Kubebuilder Documentation

Create infra

infra.yaml:

apiVersion: infra.sealos.io/v1
kind: Infra
metadata:
  name: infra-apply-test
spec:
  hosts:
  - roles: [master] # required
    count: 3 # Required
    flavor: "t2.micro"
    image: "ami-05248307900d52e3a"
  - roles: [ node ] # required
    count: 3 # Required
    flavor: "t2.micro"
    image: "ami-05248307900d52e3a"
kubectl apply -f infra.yaml

Scale down:

apiVersion: infra.sealos.io/v1
kind: Infra
metadata:
  name: infra-apply-test
spec:
  hosts:
  - roles: [master] # required
    count: 1 # Required
    flavor: "t2.micro"
    image: "ami-05248307900d52e3a"
  - roles: [ node ] # required
    count: 1 # Required
    flavor: "t2.micro"
    image: "ami-05248307900d52e3a"
kubectl apply -f infra.yaml

Scale up:

apiVersion: infra.sealos.io/v1
kind: Infra
metadata:
  name: infra-apply-test
spec:
  hosts:
    - roles: [ master ]
      count: 1
      flavor: t2.medium
      image: "ami-0d66b970b9f16f1f5"
      disks:
        - capacity: 23
          volumeType: standard
          type: "root"
        - capacity: 21
          volumeType: gp3
          type: "data"
    - roles: [ node ]
      count: 1
      flavor: t2.medium
      image: "ami-0d66b970b9f16f1f5"
      disks:
        - capacity: 11
          volumeType: gp3
          type: "root"
        - capacity: 13
          volumeType: gp3
          type: "data"
kubectl apply -f infra.yaml

Clean infra:

kubectl delete -f infra.yaml
