Virtual-Machines-Management

A Kubernetes native application which can manage Virtual Machines'S manipulation.

Features

• Create Virtual Machines
• Delete Virtual Machines
• List Virtual Machines
• Get Virtual Machines details

How to run

Custom API Server

Change directory to custom-apiserver

cd custom-apiserver

Build the Binary

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -o artifacts/simple-image/virtual-machines-apiserver

Build the Docker Image

docker build -t MYPREFIX/virtual-machines-apiserver:MYTAG ./artifacts/simple-image
docker push MYPREFIX/virtual-machines-apiserver:MYTAG

Where MYPREFIX is your Docker Hub username and MYTAG is the tag you want to use.

Deploy the Custom API Server

kubectl apply -f artifacts/example/ns.yaml
kubectl apply -f artifacts/example

Verify the Custom API Server is running

Test if the custom API server is running by checking the apiservices and the pods in the kube-system namespace:

kubectl get apiservices -n kube-system
kubectl get pods -n vms

Custom Controller

Change directory to custom-controller

cd custom-controller

Build the image

make docker-build IMG=MYPREFIX/virtual-machines-controller:MYTAG

Where MYPREFIX is your Docker Hub username and MYTAG is the tag you want to use.

Push the image

docker push MYPREFIX/virtual-machines-controller:MYTAG

Deploy the Custom Controller

1. Create a Kubernetes secret manifest for your AWS credentials, then apply it:

apiVersion: v1
kind: Secret
metadata:
  name: aws-credentials
  namespace: custom-controller-system
type: Opaque
stringData:
  access_key: <YOUR_AWS_ACCESS_KEY>
  secret_key: <YOUR_AWS_SECRET_KEY>

kubectl apply -f aws-credentials.yaml

2. Locate your operator’s deployment YAML file, typically in config/manager/manager.yaml. Change the image field to point to your custom controller image:

spec:
  containers:
    - name: manager
      image: MYPREFIX/virtual-machines-controller:MYTAG

Then apply the deployment:

make deploy IMG=MYPREFIX/virtual-machines-controller:MYTAG

3. Apply the RBAC rules:

kubectl apply -f virtualmachine-operator-permissions.yaml

Verify the Custom Controller is running

Check if the custom controller is running by checking the pods in the custom-controller-system namespace

kubectl get pods -n custom-controller-system

Create a Virtual Machine

To create a Virtual Machine, apply the following manifest:

kubectl apply -f custom-apiserver/artifacts/virtualmachine/02-virtualmachine.yaml

List Virtual Machines

To list all Virtual Machines, use the following command:

kubectl get virtualmachines

Get Virtual Machine details

To get the details of a specific Virtual Machine, use:

kubectl get virtualmachine <vm-name> -o yaml

Delete a Virtual Machine

To delete a Virtual Machine, use the following command:

kubectl delete virtualmachine <vm-name>

This will remove the Virtual Machine from the cluster.
