![]() You must run the create-route command for each of the Space CIDRs. The destination-cidr-block argument must match one of the Space CIDRs indicated by the heroku spaces:peering:info command. The destination-cidr-block must be the CIDR range for your Private Space Option 2: Add multiple routes to specific Private Space subnets $ aws ec2 create-route -route-table-id rtb-your-route-table-id -destination-cidr-block 10.0.1.0/20 -vpc-peering-connection-id pcx-111aaa111 Provide the routing table ID to the create-route AWS CLI command: $ aws ec2 create-route -route-table-id rtb-your-route-table-id -destination-cidr-block 10.0.0.0/16 -vpc-peering-connection-id pcx-111aaa111 Option 1: Add one route for entire Private Space CIDR block (recommended) Look for the route table with the same VPC ID as your VPC and obtain its route table ID.Īt this point, you can choose to either add a single route for the entire Private Space CIDR (recommended) or add specific routes for the subnets that contain resources that components in your VPC will be interacting with. Setting up routesĪfter you establish a peering connection, you must update the route table in your VPC so packets can be routed between the Private Space and the VPC.įirst, obtain your VPC’s routing table ID with the following AWS CLI command: $ aws ec2 describe-route-tables These connections have the type heroku-managed or heroku-postgresql, and they cannot be modified. Heroku manages other peering connections in the Private Space to allow private networking to certain add-on partners.

You can accept the peering connection with the spaces:peerings:accept CLI command. ![]() Pcx-111aaa111 unknown 10.100.0.0/16 pending-acceptance vpc-YOUR_VPC_ID YOUR_AWS_REGION YOUR_AWS_ID PCX ID Type CIDR Block Status VPC ID AWS Region AWS Account ID Expires Your peering request is the entry with a Status of pending-acceptance: $ heroku spaces:peerings spaces-peering-example "VpcPeeringConnectionId": "pcx-111aaa111",Īfter you make the peering request on AWS you can track it with the Heroku CLI’s spaces:peerings command. This guide demonstrates initiating peering with the AWS command-line utility’s create-vpc-peering-connection command: $ aws ec2 create-vpc-peering-connection -vpc-id vpc-YOUR_VPC_ID -peer-vpc-id vpc-e291cc85 -peer-owner-id 847227832372 ![]() To initiate a peering request you can use the AWS CLI or the AWS Management Console. You can use this information to route CIDR blocks (rather than the AWS VPC CIDR, which is a /16 block) inside your VPC.īefore you initiate a peering connection, ensure that your VPC does not overlap with the values of either AWS VPC CIDR or Unavailable CIDRs. The Space CIDRs are the CIDR blocks from which your dyno and ELB addresses are assigned. ![]() The AWS VPC CIDR field contains the CIDR block in use by the Private Space VPC you’ll peer with. The AWS Account ID and AWS VPC ID fields contain the information you’ll need when making the peering request via AWS. You can use the heroku spaces:peering:info command to retrieve this information: $ heroku spaces:peering:info spaces-peering-example To submit a peering request, you need to know the AWS Account ID and the VPC ID of your Private Space. ![]() To configure peering, you submit a peering request from your AWS VPC and then confirm it via the Heroku dashboard or CLI. Creating a peering connection to your Private Space See AWS VPC Peering documentation for details. Inter-region peering has some limitations. ![]()
