Addons

Hostman Kubernetes clusters support three add-ons: Nginx Ingress, Kubernetes Dashboard, and CSI S3. These add-ons can be installed either during the cluster creation process or afterward via the Addons section.

Nginx Ingress

Nginx Ingress is an Ingress controller that manages external traffic access to services within a Kubernetes cluster via HTTP and HTTPS. It routes traffic based on rules defined in Ingress resources.

How It Works

The Ingress controller monitors Ingress objects in Kubernetes and configures the Nginx reverse proxy to route traffic to the appropriate services. This allows access to various microservices through a single IP address, as well as setting up load balancing and routing based on domain names.

Key Features

• HTTP/HTTPS request routing
• SSL/TLS support
• Load balancing
• Managing external access to services in the cluster

Kubernetes Dashboard

Kubernetes Dashboard is a web interface for managing and monitoring a Kubernetes cluster.

The Nginx Ingress add-on is required for the Dashboard to function. When enabling Kubernetes Dashboard, Nginx Ingress will be automatically selected.

How It Works

The Dashboard provides users with a graphical interface to interact with the cluster. It allows users to view the status of pods, nodes, services, and other Kubernetes resources. The interface also supports creating, modifying, and deleting resources.

Key Features

• Cluster status overview (pods, nodes, services, configurations)
• Cluster resource management
• Instant access to pod logs and running application information
• Management of secrets and configurations

Accessing Kubernetes Dashboard

If you enable the Kubernetes Dashboard option for your cluster, you can access it from the management panel. You will need a token to log in, which can be copied from the Information tab on the cluster Dashboard.

CSI S3

CSI S3 is a plugin for the Container Storage Interface (CSI) that allows the use of S3-compatible storage with Kubernetes.

How It Works

CSI S3 enables the dynamic attachment of object storage compatible with S3 (such as Ceph, MinIO, AWS S3) as standard persistent volumes for use in Kubernetes. This is particularly useful for storing large amounts of data in containerized applications.

Key Features

• Connecting S3 storage as persistent volumes
• Support for dynamic volume creation and deletion
• Flexibility in using various S3-compatible storage systems
