Getting Started


Welcome to Critical Stack. The Critical Stack (CS) user interface is a streamlined and simple way to manage your infrastructure and deploy containerized workloads. To learn more about Critical Stack, containers, or container orchestration visit:

The top-level menu facilitates global navigation along with showing available components and cluster information. Multiple users can access the UI at once. All users have access to current information. Role-based permissions determine which actions and administrative tasks are available. The information in the Critical Stack UI changes according to the namespace you select. When you log into your CS cluster, the default homepage is the Node information, as shown in Figure 1.
