Сreate subnets for a managed cluster using web UI

Before creating an L2 template, create the required subnets to use in the L2 template to allocate IP addresses for the managed cluster nodes.

To create subnets for a managed cluster using web UI:

  1. Log in to the Container Cloud web UI with the operator permissions.

  2. Switch to the required project using the Switch Project action icon located on top of the main left-side navigation panel.

  3. In the Clusters tab, click the required cluster and scroll down to the Subnets section.

  4. Click Add Subnet.

  5. Fill out the Add new subnet form as required:

    • Subnet Name

      Subnet name.

    • CIDR

      A valid IPv4 CIDR, for example, 10.11.0.0/24.

    • Include Ranges Optional

      A list of IP address ranges within the given CIDR that should be used in the allocation of IPs for nodes. The gateway, network, broadcast, and DNS addresses will be excluded (protected) automatically if they intersect with one of the range. The IPs outside the given ranges will not be used in the allocation. Each element of the list can be either an interval 10.11.0.5-10.11.0.70 or a single address 10.11.0.77. The includeRanges parameter is mutually exclusive with excludeRanges.

    • Exclude Ranges Optional

      A list of IP address ranges within the given CIDR that should not be used in the allocation of IPs for nodes. The IPs within the given CIDR but outside the given ranges will be used in the allocation. The gateway, network, broadcast, and DNS addresses will be excluded (protected) automatically if they are included in the CIDR. Each element of the list can be either an interval 10.11.0.5-10.11.0.70 or a single address 10.11.0.77. The excludeRanges parameter is mutually exclusive with includeRanges.

    • Gateway Optional

      A valid gateway address, for example, 10.11.0.9.

  6. Click Create.
