Policy

Manage policies and attributes supported by the Container Cluster Management service.
In Container Cluster Management, you can delve into the intricacies of policies and attributes vital for optimal container orchestration. This section unpacks key policies such as resource quotas, limit ranges, and network policies, each playing a pivotal role in balancing resource allocation with workload execution.
The guide simplifies complex container management components designed for seasoned users, ensuring users can effectively optimize their clusters. Navigate to understand the significance of each policy and its associated attributes for successful cluster orchestration.To view the different policies, follow these steps to access the data you need:
  1. Log into CCM.
  2. Proceed to the CCM dashboard. This serves as the central hub for all cluster management activities.
  3. In the dashboard, locate the
    Cluster table
    , positioned towards the bottom of the page. This table lists all the clusters available under your management.
  4. Identify and choose the desired cluster by selecting it within the
    Cluster table
    . This action will direct you to a detailed view of the selected cluster.
  5. Within the cluster details view, navigate to the
    Policy
    tab. Here, you will find options to view and manage Persistent Volumes, Persistent Volume Claims, and Storage Classes associated with the selected cluster.
The Policy section consists of the following sub-sections: Resource quotas, Limit ranges, Pod disruption budgets, and Network policies.
