VPC API

Introduction

VPC allows you to build your own Virtual Private Cloud on top of Scaleway’s shared public cloud.

One default VPC for every available region is automatically created in each Scaleway Project.

VPC currently comprises the regional Private Networks product. Layer 2 regional Private Networks sit inside the layer 3 VPC. Private Networks allows Scaleway resources (Instances, Load Balancers, Managed Databases etc.) within a single region to be interconnected through a dedicated, private, and flexible .

You can add as many resources to your networks as you want, and add up to eight (8) different networks per resource. This allows you to run services isolated from the public internet and expose them to the rest of your infrastructure without worrying about public network filtering.

Concepts

Refer to our to find definitions of all concepts and terminology related to VPC.

Quickstart

1. Configure your environment variables

   Note

   This is an optional step that seeks to simplify your usage of the API. See the section below for help choosing an Availability Zone and Region. You can find your Project ID in the .

   export SCW_SECRET_KEY="<API secret key>"
   export SCW_DEFAULT_REGION="<Scaleway region>"
   export SCW_DEFAULT_ZONE="<Scaleway Availability Zone>"
   export SCW_PROJECT_ID="<Scaleway Project ID>"
   

2. Create a Private Network. Run the following command to create a Private Network. You can customize the details in the payload (name, tags etc.) to your needs.

   curl -X POST \
       -H "X-Auth-Token: $SCW_SECRET_KEY" \
       -H "Content-Type: application/json" \
       "https://api.scaleway.com/vpc/v2/regions/$SCW_DEFAULT_REGION/private-networks" \
       -d '{
           "name": "My new Private Network",
           "project_id": "'"$SCW_PROJECT_ID"'", 
           "tags": ["test", "dev"]
       }'
   

   Tip

   Keep the id field of the response: it is your Private Network ID, and is useable across all Scaleway products that support Private Networks. It may be useful to you to export the Private Network ID as a new environment variable export PN_ID="<Your Private Network ID>

3. Attach a resource to your Private Network. Each Scaleway product has its own API to interact with Private Networks. To attach an Instance, Managed Database, Elastic Metal server, Load Balancer or Public Gateway to your Private Network, see instructions in the documentation of the relevant product API. Here, we take the example of an Instance.

   Use the following call to attach an Instance to your Private Network. Ensure you replace <Instance ID> with the ID of your Instance, and <Private Network ID> with the ID of your Private Network. Note that the Instance must be in an Availability Zone that is part of the region of your Private Network.

   curl -X POST \
       -H "X-Auth-Token: $SCW_SECRET_KEY" \
       -H "Content-Type: application/json" \
       "https://api.scaleway.com/instance/v1/zones/$SCW_DEFAULT_ZONE/servers/<Instance ID>/private_nics" \
       -d '{"private_network_id": "<Private Network ID>"}'
   

   Tip

   Keep the id field of the response: it is your Private NIC ID. It may be useful to you to export the Private NIC ID as a new environment variable export NIC_ID="<Your Private NIC ID>.

   Tip

   Keep the mac_address field of the response, as it will allow you to identify the Private NIC inside your Instance. If successful, a new network interface will appear inside your Instance, ready to be configured to transmit traffic to other Instances of the same network, with the MAC address returned by the API call.

4. Confirm that the network interface has been plugged in. To do this, connect to your Instance and run dmseg. You should see an output similar to the following:

   [1579004.592869] pci 0000:00:05.0: [1af4:1000] type 00 class 0x020000
   [1579004.594835] pci 0000:00:05.0: reg 0x10: [io  0x0000-0x003f]
   [1579004.596715] pci 0000:00:05.0: reg 0x14: [mem 0x00000000-0x00000fff]
   [1579004.598732] pci 0000:00:05.0: reg 0x20: [mem 0x00000000-0x00003fff 64bit pref]
   [1579004.600765] pci 0000:00:05.0: reg 0x30: [mem 0x00000000-0x0007ffff pref]
   [1579004.603819] pci 0000:00:05.0: BAR 6: assigned [mem 0xc0100000-0xc017ffff pref]

   [1579004.605555] pci 0000:00:05.0: BAR 1: assigned [mem 0xc0003000-0xc0003fff]
   [1579004.606383] pci 0000:00:05.0: BAR 0: assigned [io  0x1000-0x103f]
   [1579004.607212] virtio-pci 0000:00:05.0: enabling device (0000 -> 0003)

   [1579004.644930] virtio_net virtio3 ens5: renamed from eth0
   

5. Confirm the presence of the network interface, and confirm its name if several networks are plugged into your Instance. To do this, run ip -br link. You should see an output similar to the following:

   lo               UNKNOWN        00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
   ens2             UP             de:1c:94:44:d0:04 <BROADCAST,MULTICAST,UP,LOWER_UP>
   ens5             DOWN           02:00:00:00:00:31 <BROADCAST,MULTICAST>
   ens6             DOWN           02:00:00:00:01:5b <BROADCAST,MULTICAST>
   ens7             DOWN           02:00:00:00:01:5e <BROADCAST,MULTICAST>
   

6. Configure the Instance's IP address. DHCP is activated by default on new Private Networks, and automatically assigns IP addresses to resources on the network. If you have an older Private Network, and either activate DHCP for automatic IP configuration, or the network interface on your Instance if necessary.

7. Delete your Private NIC, which equates to unplugging your Instance from the Private Network. Use the following call. Ensure you replace <Instance ID> with the ID of your Instance, <Private Network ID> with the ID of your Private Network, and <NIC ID> with the ID of your Private NIC.

   curl -X DELETE \
       -H "X-Auth-Token: $SCW_SECRET_KEY" \
       -H "Content-Type: application/json" \
       "https://api.scaleway.com/instance/v1/zones/$SCW_DEFAULT_ZONE/servers/<Instance ID>/private_nics/<NIC ID>"
   

   The network interface disappears from your Instance.

8. Delete your Private Network. Use the following call. Ensure you replace <Private Network ID> with the ID of your Private Network.

   curl -X DELETE \
       -H "X-Auth-Token: $SCW_SECRET_KEY" \
       -H "Content-Type: application/json" \
       "https://api.scaleway.com/vpc/v2/regions/$SCW_DEFAULT_REGION/private-networks/<Private Network ID>"
   

   Note

   Private Networks must be empty to be deleted. Ensure you have detached all resources from your network prior to deletion.
