Infrastructure

DX Cloud runs on Kubernetes clusters. Kubernetes clusters are sets of node machines running containerized applications. One of the primary advantages of Kubernetes clusters is that they automatically manage your cluster to match the configured desired state.

Check out the subsections below to get an idea of what the Cockpit displays for you regarding Clusters.

Kubernetes flow

Let’s say you deploy your application with the desired state of having 4 nodes of your application running. If 1 of the nodes crashes, we see just 3 nodes are active, so we add 1 more to meet the desired state.

Overview

The Infrastructure Overview section in the Cockpit displays information about the clusters you have available in your DX Cloud setup. There are typically production and integration clusters at a minimum, but each setup is different.

clusters overview

What info is displayed?

The tab display the following information:

  • Cloud provider (such as rke standing for Rancher Kubernetes)

  • Version

  • Number of nodes

  • Created on (when the cluster was created)

There is also a table that shows more detailed cluster information such as:

  • Name (the name of the cluster)

  • Version

  • External IP

  • Operating System (OS)

  • CPU usage in percentage

  • Memory usage in percentage

  • Age of the cluster

Events

The Infrastructure Events section in the Cockpit displays information about the events within the cluster. These events are objects that show you exactly what is occurring inside your cluster, such as scheduler decisions or why some pods are being evicted from a node.

You can select up to the last 7 days for this filter.
