Input
This building block consumes 5 input parameters
Name | Format | Description |
---|---|---|
project Required |
STRING |
Project ID for this request |
filter |
STRING |
A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either =, !=, >, or <. For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance. You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake"). By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example, (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) |
maxResults |
INTEGER |
The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500) |
orderBy |
STRING |
Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by name or creationTimestamp desc is supported |
pageToken |
STRING |
Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results |

This building block provides 35 output parameters
Name | Format | Description |
---|---|---|
id |
STRING |

items[].allowed[] |
OBJECT |
|
items[].allowed[].IPProtocol |
STRING |
The IP protocol to which this rule applies. The protocol type is required when creating a firewall rule. This value can either be one of the following well known protocol strings (tcp, udp, icmp, esp, ah, ipip, sctp) or the IP protocol number |
items[].allowed[].ports[] |
STRING |
|
items[].creationTimestamp |
STRING |
[Output Only] Creation timestamp in RFC3339 text format |

STRING |
An optional description of this resource. Provide this field when you create the resource |
items[].destinationRanges[] |
STRING |
|
items[].direction |
ENUMERATION |
Direction of traffic to which this firewall applies, either |
items[].disabled |
BOOLEAN |
Denotes whether the firewall rule is disabled. When set to true, the firewall rule is not enforced and the network behaves as if it did not exist. If this is unspecified, the firewall rule will be enabled |
items[].id |
INTEGER |
[Output Only] The unique identifier for the resource. This identifier is defined by the server |
items[].kind |
STRING |
[Output Only] Type of the resource. Always compute#firewall for firewall rules |

OBJECT |
The available logging options for a firewall rule |
items[].logConfig.enable |
BOOLEAN |
This field denotes whether to enable logging for a particular firewall rule |

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?. The first character must be a lowercase letter, and all following characters (except for the last character) must be a dash, lowercase letter, or digit. The last character must be a lowercase letter or digit |
