Creating a Net

You can create a Net to isolate your resources in a virtual network dedicated to your account.

Using Cockpit v2, you can create a Net resource only (basic version), or you can create a Net with its associated resources (Subnets, internet service, NAT service) and configure it within a same creation request.

Creating a Net Using Cockpit v2

Basic Version:

  1. In the Nets dashboard, click IconAddFull Create Net.
    The CREATE NET dialog box appears.

  2. Click or access the basic version at the bottom of the dialog box.

  3. In the Name field, type a name for the Net.

    This action adds a Name tag of 255 characters maximum. You can use any character, including accented letters.

  4. In the IP range field, type the range of IPs for your Net, in CIDR notation.

  5. (optional) From the VM tenancy list, select Dedicated to place the virtual machines (VMs) created in the Net on dedicated servers. For more information, see About VMs > VM Tenancy and Dedicated VMs.

  6. Click Create.
    The Net is created.

  7. (optional) To disable the network enhancement allowing VMs of a same Subnet to communicate with one another without security group rules required, add a tag to your Net with osc.fcu.enable_lan_security_groups as key. For more information about how to add a tag, see Adding or Removing Tags. For more information about this network enhancement, see About VPCs > Subnet Routing and Security.

    • This tag must be added to your Net before creating Subnets into it.

    • The value of this tag is not taken into account, you can therefore specify any value for this tag.

Open the Create Net Window

In the Nets & Subnets dashboard, click IconAddFull Create Net.
The CREATE NET dialog box appears.

Check Available Resources

  1. Check the list to see whether you have enough resources available before you start.

  2. Click Start.
    The Net & Subnets selection screen appears.

Configure Your Net

Type the Net IP Range, Select the Number of Subnets, and Modify their Attributes

  1. Type the range of IPs for your Net and select its Subnet mask from the list.

  2. Select the number of Subnets you want to create using the plus IconPlusButton and minus IconMinusButton buttons.

  3. (optional) Modify the Subnet allocation, type a name for each Subnet, and select its Subregion.

    • The Subnet CIDR block must be part of the Net CIDR block.

    • If you create several Subnets in a Net, their CIDR blocks must not overlap.

  4. Click Next.
    The Internet Service selection screen appears.

Configure your Internet Service

Choose a Name and Direct the Internet Traffic

  1. In the Internet service name field, type a name for the internet service.

    This action adds a Name tag of 255 characters maximum. You can use any character, including accented letters.

  2. From the list, select the Subnet where the route table will direct the network traffic.

  3. Click Next.
    The NAT Service selection screen appears.

Configure your NAT Service

Choose a Name and Select a Public IP

  1. In the NAT service name field, type a name for the NAT service.

    This action adds a Name tag of 255 characters maximum. You can use any character, including accented letters.

  2. Select:

    • Select a public IP to select the public IP you want to associate with the NAT service.

    • Create a new public IP to create a new public IP and associate it with the NAT service.

  3. Click Next.
    The Subnets Connection selection screen appears.

Configure the Subnets Connection

  1. Select the Subnets you want to connect to your NAT service.

    Subnets will be connected indirectly to the internet through a single public IP. A route to the internet service will be created in each route table to the NAT service.

    To do so, you must have created at least two Subnets in the Net & Subnets selection screen.

  2. Click Next.
    The Summary screen appears.

Confirm the Creation

Choose the Net Name and Review Your Settings

  1. Type a name for the Net.

    This action adds a Name tag of 255 characters maximum. You can use any character, including accented letters.

  2. Review the settings you have specified for the Net and its associated resources.

  3. Click Create.
    Your Net and its associated resources are created.

Creating a VPC Using AWS CLI

Before you begin: Install and configure AWS CLI. For more information, see Installing and Configuring AWS CLI.

  1. To create a VPC, use the create-vpc command following this syntax:

    Request sample
    $ aws ec2 create-vpc \
    --profile YOUR_PROFILE \
    --cidr-block 10.0.0.0/16 \
    --instance-tenancy default \
    --endpoint https://fcu.eu-west-2.outscale.com

    This command contains the following attributes that you need to specify:

    • (optional) profile: The named profile you want to use, created when configuring AWS CLI. For more information, see Installing and Configuring AWS CLI.

    • cidr-block: The range of IPs for the VPC, in CIDR notation.

    • (optional) instance-tenancy: The tenancy option for the instances launched into the VPC (default | dedicated). For more information, see About VMs > VM Tenancy and Dedicated VMs.

      If you do not specify any option, the tenancy option is set to default.

    • endpoint: The endpoint corresponding to the Region you want to send the request to. For more information, see Installing and Configuring AWS CLI.

      The create-vpc command returns the following elements:

    • Vpc: Information about the newly created VPC. This element contains the following information:

      • InstanceTenancy: The tenancy option for the instances launched into the VPC. For more information, see About VMs > VM Tenancy and Dedicated VMs.

      • State: The state of the VPC. For more information, see About Nets.

      • VpcId: The ID of the VPC.

      • CidrBlock: The range of IPs for the VPC, in CIDR notation.

        Result sample
         {
    "Vpc": {
        "InstanceTenancy": "default",
        "State": "available",
        "VpcId": "vpc-12345678",
        "CidrBlock": "10.0.0.0/16",
    }
}

        The VPC is created.

  2. (optional) To disable the network enhancement allowing instances of a same subnet to communicate with one another without security group rules required, add a tag to your VPC with osc.fcu.enable_lan_security_groups as key. For more information about how to add a tag, see Adding or Removing Tags. For more information about this network enhancement, see About VPCs > Subnet Routing and Security.

    • This tag must be added to your VPC before creating subnets into it.

    • The value of this tag is not taken into account, you can therefore specify any value for this tag.
