Create a Custom Network Security Group

Prerequisite: You need an IONOS Cloud account with API credentials configured with the appropriate permissions.

Note: The Custom NSGs can have user-created Virtual Machines (VMs) or NICs as their members, but you cannot add nodes from the Managed Kubernetes node pools or suspended Cubes.

To create a Custom NSG, you need to use the following Cloud API POST request providing the datacenterIdand the required properties:

POST /datacenters/{datacenterId}/securitygroups

Request

curl --location 'https://api.ionos.com/cloudapi/v6/datacenters/5a88aa8b-8aa1-51f6-XXd1-XXXXXe9f31/securitygroups' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic YYXabCDeFmLMO0c2hyYUBpb25vcy5jb206I1Bha2lzdGFuXzE=' \
--data '{
    "properties": {
        "name": "NSG-1",
        "description": "Description for NSG-1"
    }
}'
