Data Source: aws_route_tables

This resource can be useful for getting back a list of route table ids to be referenced elsewhere.

Example Usage

The following adds a route for a particular cidr block to every (private kops) route table in a specified vpc to use a particular vpc peering connection.

data "aws_route_tables" "rts" {
  vpc_id = "${var.vpc_id}"

  filter {
    name   = "tag:kubernetes.io/kops/role"
    values = ["private*"]
  }
}

resource "aws_route" "r" {
  count                     = "${length(data.aws_route_tables.rts.ids)}"
  route_table_id            = "${data.aws_route_tables.rts.ids[count.index]}"
  destination_cidr_block    = "10.0.1.0/22"
  vpc_peering_connection_id = "pcx-0e9a7a9ecd137dc54"
}

Argument Reference

• filter - (Optional) Custom filter block as described below.

• vpc_id - (Optional) The VPC ID that you want to filter from.

• tags - (Optional) A mapping of tags, each pair of which must exactly match a pair on the desired route tables.

More complex filters can be expressed using one or more filter sub-blocks, which take the following arguments:

• name - (Required) The name of the field to filter by, as defined by the underlying AWS API.

• values - (Required) Set of values that are accepted for the given field. A Route Table will be selected if any one of the given values matches.

Attributes Reference

• ids - A list of all the route table ids found. This data source will fail if none are found.
