## Synopsis

- Manage route tables for AWS virtual private clouds

## Requirements

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

- python >= 2.6
- boto

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
aws_access_key string |  | AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string |  | AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key

debug_botocore_endpoint_logs
boolean
added in 2.8

Choices:
- no ←
- yes

Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.

ec2_url string |  | Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.

lookup
-

Choices:
- tag ←
- id

Look up route table by either tags or by route table ID. Non-unique tag lookup will fail. If no tags are specified then no lookup for an existing route table is performed and a new route table will be created. To change tags of a route table you must look up by id.

profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
propagating_vgw_ids - |  | Enable route propagation from virtual gateways specified by ID.

purge_routes
boolean

Choices:
- no
- yes ←

Purge existing routes that are not found in routes.

purge_subnets
boolean

Choices:
- no
- yes ←

Purge existing subnets that are not found in subnets. Ignored unless the subnets option is supplied.

purge_tags
boolean
added in 2.5

Choices:
- no ←
- yes

Purge existing tags that are not found in route table

region string |  | The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region aliases: aws_region, ec2_region
route_table_id - |  | The ID of the route table to update or delete.
routes - |  | List of routes in the route table. Routes are specified as dicts containing the keys 'dest' and one of 'gateway_id', 'instance_id', 'network_interface_id', or 'vpc_peering_connection_id'. If 'gateway_id' is specified, you can refer to the VPC's IGW by using the value 'igw'. Routes are required for present states.
security_token string |  | AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token

state
-

Choices:
- present ←
- absent

Create or destroy the VPC route table

subnets - |  | An array of subnets to add to this route table. Subnets may be specified by either subnet ID, Name tag, or by a CIDR such as '10.0.0.0/24'.
tags - |  | A dictionary of resource tags of the form: { tag1: value1, tag2: value2 }. Tags are used to uniquely identify route tables within a VPC when the route_table_id is not supplied. aliases: resource_tags

validate_certs
boolean

Choices:
- no
- yes ←

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

vpc_id - / required |  | VPC ID of the VPC in which to create the route table.

## Notes

Note

- If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence `AWS_URL` or `EC2_URL`, `AWS_ACCESS_KEY_ID` or `AWS_ACCESS_KEY` or `EC2_ACCESS_KEY`, `AWS_SECRET_ACCESS_KEY` or `AWS_SECRET_KEY` or `EC2_SECRET_KEY`, `AWS_SECURITY_TOKEN` or `EC2_SECURITY_TOKEN`, `AWS_REGION` or `EC2_REGION`
- Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
- `AWS_REGION` or `EC2_REGION` can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file

## Examples

    # Note: These examples do not set authentication details, see the AWS Guide for details.

    # Basic creation example:
    - name: Set up public subnet route table

        subnets:
          - "{{ jumpbox_subnet.subnet.id }}"
          - "{{ frontend_subnet.subnet.id }}"
          - "{{ vpn_subnet.subnet_id }}"
        routes:
          - dest: 0.0.0.0/0
            gateway_id: "{{ igw.gateway_id }}"
      register: public_route_table

    - name: Set up NAT-protected route table
      ec2_vpc_route_table:
        vpc_id: vpc-1245678
        region: us-west-1
        tags:

        subnets:
          - "{{ application_subnet.subnet.id }}"
          - 'Database Subnet'
          - '10.0.0.0/8'
        routes:
          - dest: 0.0.0.0/0
            instance_id: "{{ nat.instance_id }}"
      register: nat_route_table

    - name: delete route table
      ec2_vpc_route_table:
        vpc_id: vpc-1245678
        region: us-west-1
        route_table_id: "{{ route_table.id }}"
        lookup: id
