Welcome to your guide on how to install and utilize Volcano, an innovative batch system built on Kubernetes. Volcano empowers users to run a myriad of workloads associated with machine learning, bioinformatics, and other big data applications.

What is Volcano?

Volcano is a robust scheduling system that integrates seamlessly with popular frameworks like TensorFlow, Spark, PyTorch, and more. Imagine a busy restaurant kitchen where each chef (representing your workloads) needs a specific set of ingredients (computational resources) at the right time to create culinary masterpieces. Volcano acts as the diligent head chef, orchestrating the timing and order of each dish, ensuring that everything runs smoothly.

Prerequisites for Using Volcano

• Kubernetes 1.12+ with CRD support
• Access to a Kubernetes cluster for installation

How to Install Volcano

You can start using Volcano in two principal ways: using YAML files or through Helm.

Install with YAML Files

Follow this simple command to install Volcano on your existing Kubernetes cluster:

kubectl apply -f https://raw.githubusercontent.com/volcano-sh/volcano/master/install/volcano-development.yaml

This installation method supports both x86_64 and arm64 architecture.

Install via Helm

For a smooth official release installation, visit the helm-charts. Here’s a quick command to get you started:

bash
helm repo add volcano-sh https://volcano-sh.github.io/helm-charts
helm install volcano volcano-sh/volcano -n volcano-system --create-namespace

Monitoring Your Volcano Installation

Once Volcano is up and running, you might want to install a monitoring system to visualize the performance. Here are the commands:

bash
make TAG=latest generate-yaml
kubectl create -f _output/release/volcano-monitoring-latest.yaml

Troubleshooting Common Issues

If you encounter issues during installation, here are a few troubleshooting ideas:

• Ensure your Kubernetes version is compatible with Volcano (check the compatibility table in the documentation).
• Verify that your cluster has sufficient resources (CPU, memory) available for Volcano to run effectively.
• If specific pods are failing, check the logs using kubectl logs to identify the root cause.
