Making Kubernetes Usable: Kubernetes Dashboard Options
Kubernetes (often referred to as “K8s”) is an open-source container orchestration system for automating the deployment, scaling, and management of containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF).
What Is Kubernetes?
Kubernetes provides a platform-agnostic way to manage and scale containerized applications, making it easier to run and manage applications in a distributed environment. It is widely used in the industry for container orchestration. Some of the main features of Kubernetes include:
- Automated container deployment, scaling, and management: Kubernetes automates the process of deploying, scaling, and managing containerized applications, making it easier to run and manage applications in a distributed environment.
- Service discovery and load balancing: Kubernetes provides built-in service discovery and load balancing, allowing applications to automatically discover and communicate with each other.
- Automatic storage provisioning: Kubernetes can automatically provision and manage storage for containerized applications, including local and external storage options.
- Self-healing: Kubernetes can automatically detect and recover from failures, ensuring that applications remain available and running.
- Automatic rollouts and rollbacks: Kubernetes can automatically roll out and roll back updates to containerized applications, making it easier to manage and maintain applications.
- Horizontal scaling: Kubernetes can automatically scale up or down the number of replicas of a containerized application in response to changing demand.
- Namespaces: Kubernetes allows for the organization of resources within a cluster by creating multiple virtual clusters backed by the same physical cluster.
- Pluggable architecture: Kubernetes allows the use of various cloud providers or on-premise infrastructure and allows for customization of the control plane and the container runtime.
Why Is Kubernetes Difficult to Use?
Kubernetes is a powerful and flexible tool for managing containerized applications, but it can also be complex and difficult to use. Some reasons why Kubernetes can be difficult to use include:
- Steep learning curve: Kubernetes has many features and concepts that need to be understood in order to use the system effectively. This can make it difficult for new users to get started and become proficient with the tool.
- Complex architecture: Kubernetes has a complex architecture that includes multiple components such as the API server, etc, and kubelet (the primary node agent that runs on each node). Understanding how these components interact and how to troubleshoot issues can be difficult.
- Distributed nature: Kubernetes is designed to run containerized applications in a distributed environment, which can add complexity and make it more difficult to understand and troubleshoot issues.
- Configuration management: Kubernetes uses many configuration files that must be managed properly and remain in sync. When changes are made, it’s important to understand the impact of those changes and how they will affect the overall system.
- Cluster provisioning: Setting up and maintaining a Kubernetes cluster can be a complex process, especially for those unfamiliar with the underlying infrastructure.
Despite these challenges, Kubernetes has become a widely adopted tool, and many organizations have found it valuable for managing containerized applications at scale. There are many resources available to help users learn and become proficient with Kubernetes, including documentation, tutorials, and training courses.
What Is the Kubernetes Dashboard?
The Kubernetes Dashboard is a web-based user interface for Kubernetes clusters. It provides an easy way to manage and troubleshoot the applications and resources running on a cluster. Kubernetes dashboard functionality includes the ability to view and manage resources such as pods, services, and deployments, as well as perform tasks such as scaling and rolling out updates. It also provides access to the logs and events of the resources and gives an overall status of the cluster.
The Kubernetes Dashboard can be used to:
- View the overall health of the cluster and the resources running on it
- View and manage pods, services, and deployments
- View and manage persistent volumes and storage classes
- View and manage secrets and config maps
- View and manage network policies
- View and manage roles and role bindings
- View and manage custom resource definitions
- View and search logs and events of the resources
The Kubernetes Dashboard can be easily installed and accessed via a web browser, and it does not require command-line tools or complex configurations. It is a useful tool for developers, system administrators, and cluster operators who want to easily manage and troubleshoot their Kubernetes clusters.
Kubernetes Dashboard Alternatives
Kubernetes Dashboard is a web-based UI for managing and troubleshooting Kubernetes clusters, but some users may prefer alternatives that offer more features, customizability, integrations, ease of use, and security. Some examples of alternatives include:
Komodor
