## Synopsis

- Represents a Route resource.

- A route is a rule that specifies how certain packets should be handled by the virtual network. Routes are associated with virtual machines by tag, and the set of routes for a particular virtual machine is called its routing table. For each packet leaving a virtual machine, the system searches that virtual machine’s routing table for a single best matching route.

- Routes match packets by destination IP address, preferring smaller or more specific ranges over larger ones. If there is a tie, the system selects the route with the smallest priority value. If there is still a tie, it uses the layer three and four packet headers to select just one of the remaining matching routes. The packet is then forwarded as specified by the next_hop field of the winning route – either to another virtual machine destination, a virtual machine gateway or a Compute Engine-operated gateway. Packets that do not match any route in the sending virtual machine’s routing table will be dropped.

- A Route resource must have exactly one specification of either nextHopGateway, nextHopInstance, nextHopIp, or nextHopVpnTunnel.

## Requirements

The below requirements are needed on the host that executes this module.

- python >= 2.6

- requests >= 2.18.4

- google-auth >= 1.3.0

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
auth_kind string / required | Choices: application machineaccount serviceaccount | The type of credential used.
description string added in 2.7 |  | An optional description of this resource. Provide this property when you create the resource.
dest_range string / required |  | The destination range of outgoing packets that this route applies to. Only IPv4 is supported.
env_type string |  | Specifies which Ansible environment you're running this module within. This should not be set unless you know what you're doing. This only alters the User Agent string for any API requests.
name string / required |  | Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
network dictionary / required |  | The network that this route applies to. This field represents a link to a Network resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_network task and then set this network field to "{{ name-of-resource }}"
next_hop_gateway string |  | URL to a gateway that should handle matching packets. Currently, you can only specify the internet gateway, using a full or partial valid URL: * https://www.googleapis.com/compute/v1/projects/project/global/gateways/default-internet-gateway * projects/project/global/gateways/default-internet-gateway * global/gateways/default-internet-gateway .
next_hop_instance dictionary |  | URL to an instance that should handle matching packets. You can specify this as a full or partial URL. For example: * https://www.googleapis.com/compute/v1/projects/project/zones/zone/ instances/instance * projects/project/zones/zone/instances/instance * zones/zone/instances/instance . This field represents a link to a Instance resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_instance task and then set this next_hop_instance field to "{{ name-of-resource }}"
next_hop_ip string |  | Network IP address of an instance that should handle matching packets.
next_hop_vpn_tunnel dictionary |  | URL to a VpnTunnel that should handle matching packets. This field represents a link to a VpnTunnel resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_vpn_tunnel task and then set this next_hop_vpn_tunnel field to "{{ name-of-resource }}"
priority integer |  | The priority of this route. Priority is used to break ties in cases where there is more than one matching route of equal prefix length. In the case of two routes with equal prefix length, the one with the lowest-numbered priority value wins. Default value is 1000. Valid range is 0 through 65535.
project string |  | The Google Cloud Platform project to use.
scopes list |  | Array of scopes to be used.
service_account_contents jsonarg |  | The contents of a Service Account JSON file, either in a dictionary or as a JSON string that represents it.
service_account_email string |  | An optional service account email address if machineaccount is selected and the user does not wish to use the default email.
service_account_file path |  | The path of a Service Account JSON file if serviceaccount is selected as type.
state string | Choices: present ← absent | Whether the given object should exist in GCP
tags list |  | A list of instance tags to which this route applies.

## Notes

Note

- API Reference: https://cloud.google.com/compute/docs/reference/rest/v1/routes

- Using Routes: https://cloud.google.com/vpc/docs/using-routes

- for authentication, you can set service_account_file using the c(gcp_service_account_file) env variable.

- for authentication, you can set service_account_contents using the c(GCP_SERVICE_ACCOUNT_CONTENTS) env variable.

- For authentication, you can set service_account_email using the `GCP_SERVICE_ACCOUNT_EMAIL` env variable.

- For authentication, you can set auth_kind using the `GCP_AUTH_KIND` env variable.

- For authentication, you can set scopes using the `GCP_SCOPES` env variable.

- Environment variables values will only be used if the playbook values are not set.

- The service_account_email and service_account_file options are mutually exclusive.

        service_account_file: "{{ gcp_cred_file }}"
        state: present
      register: network

    - name: create a route

        network: "{{ network }}"
        tags:
        - backends
