3. Click the name of the subnet.

4. Select Action > Assign Project.

5. After adding or removing projects, click Assign.

#Assigning Namespaces

Assigning subnets to specific namespaces allows for finer network isolation.

Note: The assignment process will rebuild the gateway, and outbound data packets will be discarded! Please ensure no business applications are currently accessing external clusters.

2. In the left sidebar, click on Network Management > Subnets.

3. Click the name of the subnet.

4. Select Action > Assign Namespace.
