## Synopsis

- Creates and removes firewall rules.

## Requirements

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

- python >= 2.6
- cs >= 0.6.10

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
account string |  | Account the firewall rule is related to.
api_http_method string | Choices: get post | HTTP method used to query the API endpoint. If not given, the `CLOUDSTACK_METHOD` env variable is considered. As the last option, the value is taken from the ini config file, also see the notes. Fallback value is `get` if not specified.
api_key string |  | API key of the CloudStack API. If not given, the `CLOUDSTACK_KEY` env variable is considered. As the last option, the value is taken from the ini config file, also see the notes.
api_region string | Default: "cloudstack" | Name of the ini section in the `cloustack.ini` file. If not given, the `CLOUDSTACK_REGION` env variable is considered.
api_secret string |  | Secret key of the CloudStack API. If not set, the `CLOUDSTACK_SECRET` env variable is considered. As the last option, the value is taken from the ini config file, also see the notes.
api_timeout integer |  | HTTP timeout in seconds. If not given, the `CLOUDSTACK_TIMEOUT` env variable is considered. As the last option, the value is taken from the ini config file, also see the notes. Fallback value is 10 seconds if not specified.
api_url string |  | URL of the CloudStack API e.g. https://cloud.example.com/client/api. If not given, the `CLOUDSTACK_ENDPOINT` env variable is considered. As the last option, the value is taken from the ini config file, also see the notes.
cidrs list | Default: "0.0.0.0/0" | List of CIDRs (full notation) to be used for firewall rule. Since version 2.5, it is a list of CIDR. aliases: cidr
domain string |  | Domain the firewall rule is related to.
end_port integer |  | End port for this rule. Considered if protocol=tcp or protocol=udp. If not specified, equal start_port.
icmp_code integer |  | Error code for this icmp message. Considered if protocol=icmp.
icmp_type integer |  | Type of the icmp message being sent. Considered if protocol=icmp.
ip_address string |  | Public IP address the ingress rule is assigned to. Required if type=ingress.
network string |  | Network the egress rule is related to. Required if type=egress.
poll_async boolean | Choices: no yes ← | Poll async jobs until job has finished.
project string |  | Name of the project the firewall rule is related to.
protocol string | Choices: tcp ← udp icmp all | Protocol of the firewall rule. `all` is only available if type=egress.
start_port integer |  | Start port for this rule. Considered if protocol=tcp or protocol=udp. aliases: port
state string | Choices: present ← absent | State of the firewall rule.
tags list added in 2.4 |  | List of tags. Tags are a list of dictionaries having keys key and value. To delete all tags, set an empty list e.g. tags: []. aliases: tag
type string | Choices: ingress ← egress | Type of the firewall rule.
zone string |  | Name of the zone in which the virtual machine is in. If not set, default zone is used.

## Notes

Note

- Ansible uses the `cs` library’s configuration method if credentials are not provided by the arguments `api_url`, `api_key`, `api_secret`. Configuration is read from several locations, in the following order. The `CLOUDSTACK_ENDPOINT`, `CLOUDSTACK_KEY`, `CLOUDSTACK_SECRET` and `CLOUDSTACK_METHOD`. `CLOUDSTACK_TIMEOUT` environment variables. A `CLOUDSTACK_CONFIG` environment variable pointing to an `.ini` file. A `cloudstack.ini` file in the current working directory. A `.cloudstack.ini` file in the users home directory. Optionally multiple credentials and endpoints can be specified using ini sections in `cloudstack.ini`. Use the argument `api_region` to select the section name, default section is `cloudstack`. See https://github.com/exoscale/cs for more information.
- A detailed guide about cloudstack modules can be found in the CloudStack Cloud Guide.
- This module supports check mode.

## Examples

    - name: Allow inbound port 80/tcp from 1.2.3.4 to 4.3.2.1
      cs_firewall:
        ip_address: 4.3.2.1
        port: 80
        cidr: 1.2.3.4/32
      delegate_to: localhost

    - name: Allow inbound tcp/udp port 53 to 4.3.2.1
      cs_firewall:
        ip_address: 4.3.2.1
        port: 53
        protocol: '{{ item }}'
      with_items:
      - tcp
      - udp
      delegate_to: localhost

    - name: Ensure firewall rule is removed
      cs_firewall:
        ip_address: 4.3.2.1
        start_port: 8000
        end_port: 8888
        cidr: 17.0.0.0/8
        state: absent
      delegate_to: localhost

    - name: Allow all outbound traffic
      cs_firewall:
        network: my_network
        type: egress
        protocol: all
      delegate_to: localhost

    - name: Allow only HTTP outbound traffic for an IP
      cs_firewall:
        network: my_network
        type: egress
        port: 80
        cidr: 10.101.1.20
      delegate_to: localhost
