Copy code
func main() {
        pulumi.Run(func(ctx *pulumi.Context) error {
                // Read in some ENV, which will be the branch name eventually
                branch := os.Getenv("BRANCH")
                // Read back the Test VPC and public subnets
                v := "vpc-###############"
                vpc, err := ec2.LookupVpc(ctx, &ec2.LookupVpcArgs{Id: &v})
                if err != nil {
                        return err
                }
                privateSg, err := ec2.NewSecurityGroup(ctx, "Test-" + branch + "-priv", &ec2.SecurityGroupArgs{
                        VpcId: pulumi.String(vpc.Id),
                })
                if err != nil{
                        return err
                }
                ctx.Export("sg", privateSg.Id)
                return nil
        })
}
I've removed the vpc Id from the variable and replaced it with ####s

There might be a documentation issue - try 
privateSg.ID
I noticed in this example: https://github.com/pulumi/examples/blob/master/aws-go-webserver/main.go 
ID
is used to reference the sg id.

Hmmm. That gives a different error:
Copy code
./main.go:121:29: cannot use privateSg.CustomResourceState.ID (type func() pulumi.IDOutput) as type pulumi.Input in argument to ctx.Export:
        func() pulumi.IDOutput does not implement pulumi.Input (missing ElementType method)
no wait... my bad... I needed 
group.ID()
not 
group.ID
it seems
That seems to work ok now. I'm not sure I completely understand why, but it keeps me moving forward, thanks.
