Network Policies ​

Network Policies is one of the most important network resource in Terminus OS. They define how the network connects. The system utilizes a sandbox mechanism for network policies, which restricts interactions based on the namespace. This provides isolation between the networks of different users and applications.

As shown in the image above, the Network Policies in the Control Hub have two parts:

  • Ingress Rule
    Shows a list of rules that specify which incoming traffic is allowed into a Namespace:
    1. Only the traffic from the pod in the namespace, which matches the label specified in the rule, is allowed.
    2. The AND logic is applied for each label within a rule.
    3. The OR logic is applied between the rules in the list.

  • Egress Rule
    Similar to the Ingress Rule, it also displays a list of rules that specify which outgoing traffic is allowed out of a Namespace.

CRDs ​

CRDs

CRDs list all the Kubernetes-based Custom Resource Definitions (CRDs) in Terminus OS. Many cloud-native features of Terminus OS depend on these CRDs.

Details ​

Shows the name, group, scope level, and creation time of the CRD. There are two types of CRD scopes:

  • Namespace
    Indicates that each custom resource belongs to a namespace.

  • Cluster
    Indicates that each custom resource must be globally unique and does not belong to any Namespace. For instance, the Namespace itself is a resource at the cluster level.

Custom Resource ​

Lists all the custom resources under this CRD, including their names and creation times. Each custom resource has two action buttons to the right.

  • Delete
    Deletes this resource.

  • Edit YAML
    Manually edits the YAML file of the custom resource. After editing, click OK to save the change to the system.
