getRouteTable function

aws.ec2.RouteTable provides details about a specific Route Table.

This resource can prove useful when a module accepts a Subnet ID as an input variable and needs to, for example, add a route in the Route Table.

Example Usage

The following example shows how one might accept a Route Table ID as a variable and use this data source to obtain the data necessary to create a route.

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const config = new pulumi.Config();
const subnetId = config.requireObject<any>("subnetId");
const selected = aws.ec2.getRouteTable({
    subnetId: subnetId,
});
const route = new aws.ec2.Route("route", {
    routeTableId: selected.then(selected => selected.id),
    destinationCidrBlock: "10.0.1.0/22",
    vpcPeeringConnectionId: "pcx-45ff3dc1",
});

import pulumi
import pulumi_aws as aws

config = pulumi.Config()
subnet_id = config.require_object("subnetId")
selected = aws.ec2.get_route_table(subnet_id=subnet_id)
route = aws.ec2.Route("route",
    route_table_id=selected.id,
    destination_cidr_block="10.0.1.0/22",
    vpc_peering_connection_id="pcx-45ff3dc1")

using System.Collections.Generic;
using System.Linq;
using Pulumi;
using Aws = Pulumi.Aws;

return await Deployment.RunAsync(() =>
{
    var config = new Config();
    var subnetId = config.RequireObject<dynamic>("subnetId");
    var selected = Aws.Ec2.GetRouteTable.Invoke(new()
    {
        SubnetId = subnetId,
    });

    var route = new Aws.Ec2.Route("route", new()
    {
        RouteTableId = selected.Apply(getRouteTableResult => getRouteTableResult.Id),
        DestinationCidrBlock = "10.0.1.0/22",
        VpcPeeringConnectionId = "pcx-45ff3dc1",
    });

});

		return nil
	})
