    Provides a resource to bind a subnet to a route table. A subnet is always bound to a route table; when it is not bound to any custom route table it stays on its VPC default route table. Deleting this resource rebinds the subnet back to the default route table.

    Example Usage

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

const foo = new ucloud.Vpc("foo", {
    name: "tf-example-vpc",
    tag: "tf-example",
    cidrBlocks: ["192.168.0.0/16"],
});
const fooSubnet = new ucloud.Subnet("foo", {
    name: "tf-example-subnet",
    tag: "tf-example",
    cidrBlock: "192.168.1.0/24",
    vpcId: foo.vpcId,
});
const fooRouteTable = new ucloud.RouteTable("foo", {
    name: "tf-example-route-table",
    tag: "tf-example",
    vpcId: foo.vpcId,
});
const fooRouteTableAssociation = new ucloud.RouteTableAssociation("foo", {
    subnetId: fooSubnet.subnetId,
    routeTableId: fooRouteTable.routeTableId,
});

    import pulumi
