Create Kubernetes Cluster

Introduction

The Kubernetes cluster is a container management platform that allows users to manage their applications in a scalable and automated manner. With Kubernetes, users can easily distribute their workloads across multiple nodes and benefit from scalability and self-healing capabilities. This product is specifically designed for developers and operations teams to manage their infrastructure easily and confidently.

Features of the Creation Page

• Cluster Name Selection: Users must choose a unique name for their cluster.

• Version Selection: Users can select the Kubernetes version for the cluster, allowing them to benefit from new features and security improvements.

• Number of Worker Nodes: Users can specify the number of worker nodes that will run the workloads.

• Number of Master Nodes: Determine the number of master nodes for cluster management and ensuring high availability.

• Hardware Selection (Offering): Users can choose the type of hardware required for the nodes, which includes various options in terms of processing power and memory.

• Network Selection: Users can select the network to be used for the cluster.

• SSH Key in Kubernetes Cluster: To ensure the security of the Kubernetes cluster, users must enter their public SSH key. This process is important for the following reasons:

  • Secure Access: The public SSH key enables secure connections to the cluster nodes and prevents unauthorized access.
  • Easy Management: By entering the public key, users can easily connect to the nodes and make necessary configurations.
  • Reduced Security Risks: Using SSH keys instead of passwords enhances security and reduces potential risks.
  • By entering the public SSH key, users can ensure the security and easy management of the Kubernetes cluster.

• Create Cluster Button: After filling in all the required fields, users can launch their new cluster by clicking the "Create" button.

Steps to Create a Cluster

1. Select Cluster Name: Enter a unique name for your cluster.
2. Select Version: Choose the desired Kubernetes version from the dropdown menu.
3. Number of Worker Nodes: Specify the number of worker nodes.
4. Number of Master Nodes: Determine the number of master nodes.
5. Select Hardware: Choose the type of hardware required for the nodes.
6. Select Network: Select the network you want to use for the cluster.

Note

Having a Layer 3 network (virtual router) is mandatory for cluster creation.

Create New Network:

It is recommended to create a new network before creating the Kubernetes cluster. Avoid using pre-existing networks to prevent conflicts with system roles. Otherwise, the cluster creation process may fail.

7. Enter SSH Key: Please enter your desired public key and select it if it exists.

Having at least one public SSH key

An SSH authentication key is essential for cluster creation.

8. Click on the Create Button: After ensuring all fields are filled, click the "Create" button.

After creating the cluster, it may take a few minutes for your cluster to be ready.
