## Synopsis

- This module can create and destroy Google Compute Engine networks and firewall rules https://cloud.google.com/compute/docs/networking. The name parameter is reserved for referencing a network while the fwname parameter is used to reference firewall rules. IPv4 Address ranges must be specified using the CIDR http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing format. Full install/configuration instructions for the gce* modules can be found in the comments of ansible/test/gce_tests.py.

## Requirements

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

- python >= 2.6
- apache-libcloud >= 0.13.3, >= 0.17.0 if using JSON credentials

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
allowed - |  | the protocol:ports to allow (tcp:80 or tcp:80,443 or tcp:80-800;udp:1-25) this parameter is mandatory when creating or updating a firewall rule
credentials_file - |  | path to the JSON file associated with the service account email
fwname - |  | name of the firewall rule aliases: fwrule
ipv4_range - |  | the IPv4 address range in CIDR notation for the network this parameter is not mandatory when you specified existing network in name parameter, but when you create new network, this parameter is mandatory aliases: cidr
mode - | Choices: legacy ← auto custom | network mode for Google Cloud `legacy` indicates a network with an IP address range; `auto` automatically generates subnetworks in different regions; `custom` uses networks to group subnets of user specified IP address ranges https://cloud.google.com/compute/docs/networking#network_types
name - |  | name of the network
pem_file - |  | path to the pem file associated with the service account email This option is deprecated. Use `credentials_file`.
project_id - |  | your GCE project ID
service_account_email - |  | service account email
src_range - | Default: [] | the source IPv4 address range in CIDR notation aliases: src_cidr
src_tags - | Default: [] | the source instance tags for creating a firewall rule
state - | Choices: active present ← absent deleted | desired state of the network or firewall
subnet_desc - |  | description of subnet to create
subnet_name - |  | name of subnet to create
subnet_region - |  | region of subnet to create
target_tags - | Default: [] | the target instance tags for creating a firewall rule

## Examples

    # Create a 'legacy' Network
    - name: Create Legacy Network
      gce_net:
        name: legacynet
        ipv4_range: '10.24.17.0/24'
        mode: legacy
        state: present

    # Create an 'auto' Network
    - name: Create Auto Network
      gce_net:
        name: autonet
        mode: auto
        state: present

    # Create a 'custom' Network
    - name: Create Custom Network
      gce_net:
        name: customnet
        mode: custom
        subnet_name: "customsubnet"
        subnet_region: us-east1
        ipv4_range: '10.240.16.0/24'
        state: "present"

    # Create Firewall Rule with Source Tags
    - name: Create Firewall Rule w/Source Tags
      gce_net:
        name: default
        fwname: "my-firewall-rule"
        allowed: tcp:80
        state: "present"
        src_tags: "foo,bar"

    # Create Firewall Rule with Source Range
    - name: Create Firewall Rule w/Source Range
      gce_net:
        name: default
        fwname: "my-firewall-rule"
        allowed: tcp:80
        state: "present"
        src_range: ['10.1.1.1/32']

    # Create Custom Subnetwork
    - name: Create Custom Subnetwork
      gce_net:
        name: privatenet
        mode: custom
        subnet_name: subnet_example
        subnet_region: us-central1
        ipv4_range: '10.0.0.0/16'

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
allowed string | When specified | Rules (ports and protocols) specified by this firewall rule. Sample: tcp:80;icmp
fwname string | When specified | Name of the firewall rule. Sample: my-fwname
ipv4_range string | when specified or when a subnetwork is created | IPv4 range of the specified network or subnetwork. Sample: 10.0.0.0/16
name string | always | Name of the network. Sample: my-network
src_range list | when specified | IP address blocks a firewall rule applies to. Sample: ['10.1.1.12/8']
src_tags list | when specified while creating a firewall rule | Instance Tags firewall rule applies to. Sample: ['foo', 'bar']
state string | always | State of the item operated on. Sample: present
subnet_name string | when specified or when a subnetwork is created | Name of the subnetwork. Sample: my-subnetwork
subnet_region string | when specified or when a subnetwork is created | Region of the specified subnet. Sample: us-east1
target_tags list | when specified while creating a firewall rule | Instance Tags with these tags receive traffic allowed by firewall rule. Sample: ['foo', 'bar']
