Installing a Minimal k8s Environment with Minikube

Deploying Minikube on Proxmox VE (a Debian-based virtualization environment) requires consideration of Proxmox’s characteristics, as it is essentially a virtual machine and container management platform. You will need to create a virtual machine (VM) on Proxmox VE and then install Minikube within that VM. Below are the detailed steps:

Step 1: Create and Configure the Virtual Machine

1. Log in to the Proxmox VE management interface:

   • Typically accessed via a web browser at https://<Proxmox_IP>:8006.

2. Create a new virtual machine:

   • Click the “Create VM” button in Proxmox.
   • Name the VM, select “Linux” as the installation type, and determine the version based on the Linux distribution you intend to install (Ubuntu or Debian is recommended).

3. Configure hardware:

   • CPU: Allocate at least 2 cores.
   • Memory: Allocate at least 2GB of RAM.
   • Disk: At least 20GB of storage space.
   • Network: Ensure the VM can access the internet.

4. Install the operating system:

   • Mount the ISO file and perform the OS installation via Proxmox’s console.
   • Set the necessary user and network configurations during the installation process.

Step 2: Install and Configure Minikube

1. Connect to the virtual machine:

   • Use SSH or connect through Proxmox’s console to access the newly created VM.

2. Install kubectl:

   • Install kubectl on the VM. For Ubuntu/Debian systems, you can use the following command:

     curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
     chmod +x ./kubectl
     sudo mv ./kubectl /usr/local/bin/kubectl
     kubectl version --client
     

3. Install Minikube:

   • Download and install Minikube. For Linux systems, you can use the following command:

     curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
     chmod +x minikube
     sudo install minikube /usr/local/bin/
     

4. Start Minikube:

   • Since running inside a VM, it is recommended to use Docker as the driver. First ensure Docker is installed, then start Minikube:

     minikube start --driver=docker
     

   • This step will automatically pull the necessary Minikube Docker images and start the Kubernetes cluster.

5. Verify the installation:

   • Run kubectl get nodes to check the cluster status; it should show the minikube node in the READY state.

Step 3: Configure and Use the Kubernetes Cluster

• Interact with the cluster using the kubectl command to deploy applications or perform other management tasks.
• If you need to access applications running inside the cluster, you can use Minikube’s minikube service command to expose services.

By following the steps above, you can successfully deploy and run a Minikube Kubernetes cluster on Proxmox VE, providing a relatively isolated and resource-controlled environment for development and testing purposes.
