Is there a way I can make a cross-account VPC peering connection (as the requester) and have it succeed? Whenever I create one, it fails because the accepter needs to accept the connection. Is there a way I can bypass this so my pulumi run does not fail?
Copy code
aws:ec2:VpcPeeringConnection (0000000-vpc-000000000):
    error:   sdk-v2/provider2.go:520: sdk.helper_schema: Unable to modify EC2 VPC Peering Connection Options. EC2 VPC Peering Connection (pcx-0000000000000) is not active (current status: pending-acceptance). Please set the `auto_accept` attribute to `true` or activate the EC2 VPC Peering Connection manually.: provider=aws@6.56.1
    error: 1 error occurred:

@rough-ice-18151 funny, i'm actually working on the same exact thing right now
but that's a weird error. what are you trying to change about the peering connection?
r
I’m just creating the connection, not modifying it
s
could you share the (sanitized) args you're passing in?
r
Copy code
var conn *ec2.VpcPeeringConnection
		if conn, err = ec2.NewVpcPeeringConnection(ctx, fmt.Sprintf("%s-%s", peer.AccountId, peer.VpcId), &ec2.VpcPeeringConnectionArgs{
			VpcId:       vpc.ID(),
			PeerVpcId:   pulumi.String(peer.VpcId),
			PeerOwnerId: pulumi.String(peer.AccountId),
			AutoAccept:  pulumi.BoolPtr(false),
			Requester: ec2.VpcPeeringConnectionRequesterArgs{
				AllowRemoteVpcDnsResolution: pulumi.BoolPtr(true),
			},
			Tags: pulumi.ToStringMap(vpcOpts.Tags),
		}, pulumi.Parent(&componentResource)); err != nil {
			return nil, err
		}
For testing purposes, both vpcs are in the same account. I’m not sure if this makes a difference at all
s
ah, i think it actually does. if they're the same account and same region, you use autoaccept and not the 
peer*
arguments
Copy code
const peeringConnectionArgs = {
    vpcId: source.vpcId,
    peerVpcId: target.vpcId,
    ...(region === peerRegion && accountId === peerOwnerId
      ? { autoAccept: true }
      : { peerOwnerId, peerRegion }),
  }
r
I see… I’ll have to test this against a separate account and see if I get the same error
s
also FYI, i had no idea that same account but cross region requests can't be 
autoAccepted
either. so you effectively treat them the same way as cross account
which also means you need to throw another provider into the mix
r
I’m only pulumi-ing 1 end of the connection
At least for now 🙂
s
ah, gotcha
r
I’m trying to avoid customers running pulumi code right now, trying to keep it in-house since the project I’m working on is very early stage
I’ll give it a go cross-region first, then try cross-account and see if it succeeds
s
i'm working on a module that does some crazy under the hood for this sort of stuff. you can pass it an arbitrary number of VPCs you want created (in the same account, but any regions) as well as other VPCs you want to peer with. it spins up the VPCs and then creates a full mesh peering. the fun bit is i need to create a provider for each 
account-region
pair and then passing stuff back and forth. like ill 
createPeeringConnection
in one provider, then pass that to another provider to 
acceptPeeringConnection
r
that sounds really cool! I’m loving what pulumi can do as a recent terraform convert
s
yea, it's been a trip. we're hoping to open source it 🤞
this is what our config looks like
Copy code
config:
  aws:region: us-east-1
  networking:vpcs:
    - name: foo
      region: us-east-1
      cidrBlock: 10.100.0.0/16
    - name: bar
      cidrBlock: 10.200.0.0/16
      region: eu-central-2
  networking:peering-connections:
    - name: Primary
      cidrBlock: 10.25.0.0/16
      region: us-east-1
      vpcId: vpc-XXXXXXX
    - name: Ops
      cidrBlock: 10.0.0.0/16
      region: us-east-1
      vpcId: vpc-YYYYYY
      accountId: 1234456
so for that cross account peering to 
Ops
, it just makes the request and sets up routes, but we need to accept it elsewhere
