gcp_compute_firewall – Creates a GCP Firewall¶
New in version 2.6.
Synopsis¶
- Each network has its own firewall controlling access to and from the instances.
- All traffic to instances, even from other instances, is blocked by the firewall unless firewall rules are created to allow it.
- The default network has automatically created firewall rules that are shown in default firewall rules. No manually created network has automatically created firewall rules except for a default “allow” rule for outgoing traffic and a default “deny” for incoming traffic. For all networks except the default network, you must create any firewall rules you need.
Requirements¶
The below requirements are needed on the host that executes this module.
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0

                                             / required                     | 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

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 . This field represents a link to a Network resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_network task and then set this network field to "{{ name-of-resource }}" | |
| priority 
                    integer

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. | |
| project 
                    string

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. | ||

If neither targetServiceAccounts nor targetTags are specified, the firewall rule applies to all instances on the specified network. | ||
| target_tags
