type DefaultSecurityGroupArgs struct {
    // Can be specified multiple times for each
    // egress rule. Each egress block supports fields documented below.
    Egress interface{}
    // Can be specified multiple times for each
    // ingress rule. Each ingress block supports fields documented below.
    Ingress             interface{}
    RevokeRulesOnDelete interface{}
    // A mapping of tags to assign to the resource.
    Tags interface{}
    // The VPC ID. **Note that changing
    // the `vpc_id` will _not_ restore any default security group rules that were
    // modified, added, or removed.** It will be left in its current state
    VpcId interface{}
}

What type should I pass for

Ingress

? I tried

map[string]interface{})

. It fails with

ingress: should be a list
