Kubemarine is an open-source management tool that simplifies the deployment and maintenance of Kubernetes clusters. This article will guide you through installing Kubemarine and provide insights into its features, functionalities, and troubleshooting tips.

Why Use Kubemarine?

Kubemarine stands out due to its lightweight nature and powerful capabilities for end-to-end Kubernetes deployment. The tool is flexible, allowing customization for specific use cases, thus catering to various budget and scalability needs.

Installation Methods

There are three primary methods for installing Kubemarine: Binary Installation, Package Installation, and Installation from Sources. Choose the method that best aligns with your environment’s needs.

Kubemarine Binary Installation

1. Download the binary file for your system from the latest release.
2. Move the binary file to a separate folder.
3. Run Kubemarine by executing:

kubemarine help

Kubemarine Package Installation

1. Install the latest Python.
2. Upgrade pip:

# For Linux/MacOS
python3 -m pip install --upgrade pip

# For Windows
python -m pip install --upgrade pip

3. Set up your virtual environment (if needed).
4. Install the Kubemarine package:

# For Linux/MacOS
python3 -m pip install kubemarine

# For Windows
python -m pip install kubemarine

5. Run Kubemarine:

kubemarine help

Kubemarine Installation from Sources

This process is similar to Package Installation but involves some additional steps:

1. Download the latest release or clone the repository:

git clone https://github.com/NetcrackerKubeMarine.git

2. Navigate to the project directory:

cd kubemarine

3. Install before running Kubemarine:

# For Linux/MacOS
python3 -m pip install -e .[ansible]

# For Windows
python -m pip install -e .

4. Execute:

kubemarine help

Setting Up a Kubernetes Cluster

To set up a cluster using Kubemarine, follow these instructions:

1. Prepare your VMs or bare-metal machines based on the Recommended Hardware Requirements.
2. Create a cluster.yaml file describing your environment. Here’s a quick example:

node_defaults:
  keyfile: home/username/.ssh/id_rsa
  password: env.PASS
  username: centos
vrrp_ips:
  - 192.168.0.250
nodes:
  - name: k8s-control-plane-1
    internal_address: 10.101.0.1
    roles: [balancer, control-plane, worker]

3. Move cluster.yaml to the Kubemarine installation directory.
4. Verify your infrastructure with:

kubemarine check_iaas

5. Start the installation process:

kubemarine install

6. Finally, check the health of the new cluster:

kubemarine check_paas

Understanding the Process: An Analogy

Imagine you are organizing a large festival. Kubemarine acts like the festival organizer — it ensures everything is set up just right, from the stages (Kubernetes nodes) to safety plans (configuration settings). The steps for setting up the festival mirror the steps you follow for installing and configuring Kubemarine. Just like it’s vital for festival organizers to have a detailed plan and checklist to ensure everything runs smoothly, it’s crucial to format your cluster.yaml correctly to communicate between the different parts of your Kubernetes cluster efficiently.
