This approach allows you to tailor the cluster to your specific needs and budget while honing your skills in a controlled environment.
Purpose of Cluster
The motivation behind the creation of this Raspberry Pi cluster is to conduct benchmarks for DataFusion and Ballista projects, specifically designed for efficient operation on limited computing resources.
Here are three key reasons for the purpose of the cluster:
- Testing Distributed Systems: Running projects in Rust on the Kubernetes cluster allows for testing the resilience of distributed systems in real-world physical environments.
- IoT and Edge Computing: The cluster's cost-effectiveness and portability make it ideal for potential applications in IoT devices and edge computing, demonstrating its versatility beyond benchmarking.
- Optimizing Performance: By setting up static IP addresses and optimizing software on each Pi, the cluster ensures smooth use and performance, laying the groundwork for future exploration of query engines and running applications.
Cluster Setup Approach
To proceed with setting up your Kubernetes cluster at home for benchmarking DataFusion and Ballista projects, it's important to outline the approach for cluster setup and its underlying motivation.
The motivation behind establishing this Kubernetes cluster for less at home lies in the necessity to run performance benchmarks for the DataFusion and Ballista projects efficiently. These projects, designed for limited compute resources and developed in Rust, aim to test the resilience of distributed systems.
Additionally, the versatility of this setup extends to potential applications in IoT devices and edge computing scenarios. By exploring the functionalities of query engines within the cluster environment, you can gain insights into the performance and scalability of these technologies.
As you plan to run various applications on the cluster and share your findings in an upcoming blog post, the cluster's setup using managed Kubernetes on Compute Engine becomes pivotal for achieving your research goals effectively.
Setup Process Overview
One of the initial steps in the setup process involves configuring Raspberry Pi nodes with MicroK8s for a cost-effective Kubernetes cluster at home.
To give you a clearer picture, here are some key steps in the setup process:
- Setting Up Each Pi: Begin by setting up each Raspberry Pi node individually to ensure they're prepared for cluster integration.
- Going Remote and Disabling DHCP: Configure the nodes to operate remotely and deactivate DHCP to assign static IP addresses, facilitating stable communication within the cluster.
- Updating Software and Installing MicroK8s: Update the software on each node to the latest versions for best performance. Next, install MicroK8s on each node and add them to the Kubernetes cluster using commands like 'microk8s.add-node' and 'microk8s join' for smooth operation.
Cluster Functionality Check
After setting up each Raspberry Pi node with MicroK8s, you can proceed to verify the functionality of your Kubernetes cluster through a thorough node check. Begin by confirming successful node additions by checking essential details such as node status, IPs, OS, kernel version, and container runtime. This step guarantees that all nodes are properly integrated into the cluster and are communicating effectively.
To further ensure cluster functionality, explore running applications on the cluster. By testing various applications, you can gauge the performance and capabilities of your Kubernetes cluster accurately. This examination allows you to assess how well the cluster handles workloads and whether it meets your performance expectations.
