Configuring a Network Defense Policy (for a Cluster Using the Cloud Native Network 2.0 Model)

For clusters using the cloud native network 2.0 model, you can configure network defense policies to limit the traffic that accesses the servers where containers are deployed. If no security group policies are configured, all incoming and outgoing traffic of the servers is allowed by default.

This chapter describes how to create a network defense policy for a cluster using the cloud native network 2.0 model.

Creating a Network Defense Policy

  1. Log in to the management console.
  2. In the upper left corner of the page, select a region, click , and choose Security & Compliance > HSS.
  1. In the navigation pane on the left, choose Container Protection > Container Firewalls.
  2. (Optional) If you have enabled the enterprise project, select the enterprise project where the target server resides from the drop-down list.
  3. Click Synchronize above the cluster list to synchronize the policies created on clusters.

    The synchronization takes about 1 to 2 minutes. Wait for a while and click in the upper right corner of the list to refresh and view the latest data.

  1. Click Manage Policy in the Operation column of a cluster using the cloud native network 2.0 model.
  2. Click Create above the policy list. The Create a Security Group Policy dialog box is displayed.
