Managing and monitoring resources in a Kubernetes cluster can be a complex task, especially as your applications scale. To simplify this process and gain a comprehensive overview of your cluster, tools like Kubeview come to the rescue. Kubeview is a powerful open-source tool that provides a visual representation of your Kubernetes cluster, allowing you to explore resources and their relationships. In this blog post, we will delve into the features and benefits of Kubeview and guide you through its installation and usage.
Kubeview is a Kubernetes cluster visualization tool that offers a graphical representation of your cluster’s resources, including pods, deployments, services, and more. It provides a visual interface to explore and navigate through the various components of your cluster, helping you gain insights into resource allocation, dependencies, and performance.
Assuming that you have already installed Git and Helm on your laptop, follow the below steps
git clone https://github.com/benc-uk/kubeview cd kubeview/charts/ helm install kubeview kubeview
kubectl port-forward svc/kubeview -n default 80:80
To start using Kubeview, you need to install it in your Kubernetes cluster. Follow these steps:
Kubeview can be deployed as a Kubernetes application using a YAML manifest file. Simply apply the manifest to your cluster using the following command:
kubectl apply -f https://raw.githubusercontent.com/benc-uk/kubeview/main/deploy/kubeview.yaml
After applying the manifest, check that Kubeview is up and running by executing the following command:
kubectl get pods -n kubeview
Once Kubeview is installed, you can access its web-based interface to explore your Kubernetes cluster visually. Here’s how to get started:
Retrieve the URL to access the Kubeview dashboard by executing the following command:
kubectl --namespace kubeview port-forward service/kubeview 8080:80
This command sets up a port forward to access Kubeview on your local machine.
Open a web browser and visit http://localhost:8080 to access the Kubeview dashboard. You will be greeted with an intuitive interface that displays an overview of your cluster’s resources.
Explore your cluster by clicking on different resources in the Kubeview interface. You can drill down into pods, deployments, services, and other components to visualize their relationships and connections. Kubeview provides clear visual representations, such as node graphs and dependency diagrams, to help you understand the structure of your cluster.
Clicking on individual resources reveals detailed information about them, including resource usage, health status, and labels. You can also view logs and events associated with each resource, allowing for efficient troubleshooting and monitoring.
Kubeview offers additional advanced features that enhance your cluster exploration and monitoring experience. These include:
Search and filter capabilities: Use Kubeview’s search and filter functionalities to quickly locate specific resources or filter them based on labels, namespaces, or other criteria.
Real-time updates: Kubeview automatically updates the visual representation of your cluster as changes occur, providing you with near real-time insights into the state of your resources.
Support for multiple clusters: If you manage multiple Kubernetes clusters, Kubeview can handle them all. You can easily switch between clusters within the Kubeview interface.
