Notes

Note

  • For authentication, you can set service_account_file using the GCP_SERVICE_ACCOUNT_FILE env variable.

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

  • For authentication, you can set service_account_contents using the GCP_SERVICE_ACCOUNT_CONTENTS 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.

Return Values

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

Key Returned Description
items
complex
always
List of items

  allowed
complex
success
The list of ALLOW rules specified by this firewall. Each rule specifies a protocol and port-range tuple that describes a permitted connection.

    ip_protocol
string
success
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, sctp), or the IP protocol number.

    ports
list
success
An optional list of ports to which this rule applies. This field is only applicable for UDP or TCP protocol. Each entry must be either an integer or a range. If not specified, this rule applies to connections through any port.
Example inputs include: ["22"], ["80","443"], and ["12345-12349"].

  creationTimestamp
string
success
Creation timestamp in RFC3339 text format.

  denied
complex
success
The list of DENY rules specified by this firewall. Each rule specifies a protocol and port-range tuple that describes a denied connection.

    ip_protocol
string
success
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, sctp), or the IP protocol number.

    ports
list
success
An optional list of ports to which this rule applies. This field is only applicable for UDP or TCP protocol. Each entry must be either an integer or a range. If not specified, this rule applies to connections through any port.
Example inputs include: ["22"], ["80","443"], and ["12345-12349"].

  description
string
success
An optional description of this resource. Provide this property when you create the resource.

  destinationRanges
list
success
If destination ranges are specified, the firewall will apply only to traffic that has destination IP address in these ranges. These ranges must be expressed in CIDR format. Only IPv4 is supported.

  direction
string
success
Direction of traffic to which this firewall applies; default is INGRESS. Note: For INGRESS traffic, it is NOT supported to specify destinationRanges; For EGRESS traffic, it is NOT supported to specify sourceRanges OR sourceTags.

  disabled
boolean
success
Denotes whether the firewall rule is disabled, i.e not applied to the network it is associated with. 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.

  id
integer
success
The unique identifier for the resource.

  name
string
success
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
success
URL of the network resource for this firewall rule. If not specified when creating a firewall rule, the default network is used: global/networks/default If you choose to specify this property, you can specify the network as a full or partial URL. For example, the following are all valid URLs: https://www.googleapis.com/compute/v1/projects/myproject/global/ networks/my-network projects/myproject/global/networks/my-network global/networks/default .

  priority
integer
success
Priority for this rule. This is an integer between 0 and 65535, both inclusive. When not specified, the value assumed is 1000. Relative priorities determine precedence of conflicting rules. Lower value of priority implies higher precedence (eg, a rule with priority 0 has higher precedence than a rule with priority 1). DENY rules take precedence over ALLOW rules having equal priority.

  sourceRanges
list
success
If source ranges are specified, the firewall will apply only to traffic that has source IP address in these ranges. These ranges must be expressed in CIDR format. One or both of sourceRanges and sourceTags may be set. If both properties are set, the firewall will apply to traffic that has source IP address within sourceRanges OR the source IP that belongs to a tag listed in the sourceTags property. The connection does not need to match both properties for the firewall to apply. Only IPv4 is supported.

  sourceServiceAccounts
list
success
If source service accounts are specified, the firewall will apply only to traffic originating from an instance with a service account in this list. Source service accounts cannot be used to control traffic to an instance's external IP address because service accounts are associated with an instance, not an IP address. sourceRanges can be set at the same time as sourceServiceAccounts. If both are set, the firewall will apply to traffic that has source IP address within sourceRanges OR the source IP belongs to an instance with service account listed in sourceServiceAccount. The connection does not need to match both properties for the firewall to apply. sourceServiceAccounts cannot be used at the same time as sourceTags or targetTags.

  sourceTags
list
success
If source tags are specified, the firewall will apply only to traffic with source IP that belongs to a tag listed in source tags. Source tags cannot be used to control traffic to an instance's external IP address. Because tags are associated with an instance, not an IP address. One or both of sourceRanges and sourceTags may be set. If both properties are set, the firewall will apply to traffic that has source IP address within sourceRanges OR the source IP that belongs to a tag listed in the sourceTags property. The connection does not need to match both properties for the firewall to apply.

  targetServiceAccounts
list
success
A list of service accounts indicating sets of instances located in the network that may make network connections as specified in allowed[].
targetServiceAccounts cannot be used at the same time as targetTags or sourceTags. If neither targetServiceAccounts nor targetTags are specified, the firewall rule applies to all instances on the specified network.

  targetTags
list
success
A list of instance tags indicating sets of instances located in the network that may make network connections as specified in allowed[].
If no targetTags are specified, the firewall rule applies to all instances on the specified network.
