To create either private networks without access to outside networks or outbound networks with one-way access to upstream networks, you create a network profile with isolation and specify the isolation type.

This procedure provides the steps to create a network that supports isolation using a subnet, and includes optional steps that show how to create the network using an external subnet, security groups, or a VLAN transport zone. The network profile that uses a VLAN transport zone only supports private networks.

Prerequisites

  • Verify that all general prerequisites and prerequisites for the Automation Assembler Infrastructure as a Service (IaaS) service have been satisfied. See Prerequisites for API Use Case Examples.
  • Verify that you have the cloud account ID for the new cloud account that you added. See Adding Cloud Accounts.
  • Verify that you have the region ID for the regions you want to include in the profile. See the procedure in Create Network Profiles.
  • For simplicity, examples use us-east-1 as the external region ID.
  • Verify that you have the IDs for the non-public fabric networks you want to include in the profile. See the procedure in Create Network Profiles.

Procedure

  1. Assign the cloud account ID variable. 
    cloud_account_id='<your_cloud_account_id>'
  2. Assign the region ID variable. 
    region_id='<your_region_id>'
  3. Filter for network domains associated with the cloud account ID and in the external region ID us-east-1. 
    curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" "$url/iaas/api/network-domains?apiVersion=$api_version&"'$filter='"externalRegionId%20eq%20'us-east-1'%20and%20cloudAccountId%20eq%20'$cloud_account_id'" | jq "."
  4. Examine the response to find the IDs for the network domain that you want to include in your network profile. If you are creating a network profile with a VLAN transport zone, select a network domain that has the custom property "__transportZoneTrafficType":"VLAN_BACKED".
  5. Create a network profile that supports isolation using a subnet and IDs for a non-public network. 
    curl -X POST \
  $url/iaas/api/network-profiles?apiVersion=$api_version \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $access_token" \
  -d '{
    "name":"<your-network-profile-with-isolation-by-subnet>",
    "description":"Example Network Profile",
    "regionId":"'$region_id'",
    "isolationType" : "SUBNET",
    "isolationNetworkDomainId" : "<network_domain_id_from_response>",
    "isolatedNetworkCIDRPrefix" : "27",
    "fabricNetworkIds": [
      "<non_public_network_id1>",
      "<non_public_network_id2>"
    ],
    "tags": [ { "key": "env", "value": "prod" } ]
  }' | jq "."
    The response shows the name and ID for the network profile you created.
  6. (Optional) Create a network profile that supports isolation using an external subnet. 
    curl -X POST \
  $url/iaas/api/network-profiles?apiVersion=$api_version \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $access_token" \
  -d '{ 
    "name":"<your-network-profile-with-isolation-by-external-subnet>", 
    "description":"Example Network Profile", 
    "regionId":"'$region_id'", 
    "isolationType" : "SUBNET", 
    "isolationNetworkDomainId" : "<network_domain_id_from_response>", 
    "isolatedNetworkCIDRPrefix" : "27", 
    "isolationExternalFabricNetworkId": "<non_public_network_id1>", 
    "fabricNetworkIds": [ 
      "<non_public_network_id1>",
      "<non_public_network_id2>"
    ], 
    "tags": [ { "key": "env", "value": "prod" } ]
  }' | jq "."
    The response shows the name and ID for the network profile you created.
  7. (Optional) Create a network profile that supports isolation using security groups. 
    curl -X POST \
  $url/iaas/api/network-profiles?apiVersion=$api_version \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $access_token" \
  -d '{
    "name":"<your-network-profile-with-isolation-by-security-group>", 
    "description":"Example Network Profile", 
    "regionId":"'$region_id'", 
    "isolationType" : "SECURITY_GROUP", 
    "fabricNetworkIds": [ 
      "<non_public_network_id1>",
      "<non_public_network_id2>"
    ], 
    "tags": [ { "key": "env", "value": "prod" } ]
  }' | jq "."
    The response shows the name and ID for the network profile you created.

Example: Create various types of network profiles with isolation

The following examples include the requests used to create a network profiles that support isolation using:
  • A subnet.
  • An external subnet.
  • Security groups.
  • A VLAN transport zone.
Assign the required variables including a cloud account ID and a region ID. 
$ url='https://appliance.domain.com'
$ api_version='2021-07-15'
$ cloud_account_id='c8c3c9bfdb449475-7f703c5265a63d87-5fa34c478df36b060e1ca3551254c4033013bf3283908e4661cd1c6fb2f8b9ae-ce5aad01092b47558644f6b6615d'
$ region_id='37d6c1acf4a8275586468873c739'

Filter for network domains associated with the cloud account ID and in the external region ID us-east-1.

curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" "$url/iaas/api/network-domains?apiVersion=$api_version&"'$filter='"externalRegionId%20eq%20'us-east-1'%20and%20cloudAccountId%20eq%20'$cloud_account_id'" | jq "."
