Problems with gcp_compute_instance

Hello,

I’m branching to a problem with gcp_compute_instance. The server should be created inside a project that has a shared subnet in custom mode.

These are the individual steps to gather the informations for the network:

  • name: “Gather network information for {{ vpc_project }}”
    gcp_compute_network_info:
    filters:

  • name = “{{ vpc_network }}”
    project: “{{ vpc_project }}”
    auth_kind: “{{ gcp_cred_kind }}”
    service_account_file: “{{ gcp_cred_file }}”
    register: vpcnetwork

  • name: Create dictionary VPCselfLink
    set_fact:
    VPCselfLink: “{{ VPCselfLink|default({}) | combine( {‘selfLink’: vpcnetwork[‘items’][0].selfLink} ) }}”

  • name: “Gather subnet information from project {{ vpc_project }} and subnetwork {{ vpc_subnetwork }}”
    gcp_compute_subnetwork_info:
    region: region
    project: myproject
    filters:

  • name = “{{ vpc_subnetwork }}”
    auth_kind: “{{ gcp_cred_kind }}”
    service_account_file: “{{ gcp_cred_file }}”
    scopes:

  • https://www.googleapis.com/auth/compute
    register: vpcsubnetwork

  • name: Create dictionary selfLink
    set_fact:
    selfLink: “{{ selfLink|default({}) | combine( {‘selfLink’: vpcsubnetwork[‘items’][0].selfLink} ) }}”

  • name: “Create IP address for server {{ instancename }}”
    gcp_compute_address:
    name: “ip-{{ instancename }}”
    region: “{{ region }}”
    project: “{{ gcp_project }}”
    address_type: INTERNAL
    subnetwork: “{{ selfLink }}”
    auth_kind: “{{ gcp_cred_kind }}”
    service_account_file: “{{ gcp_cred_file }}”
    scopes:

  • https://www.googleapis.com/auth/compute
    state: present
    register: ipaddress

When I make this call for the network:

network_interfaces:

  • network: “{{ VPCselfLink }}”
  • network_ip: “{{ ipaddress.address }}”
  • subnetwork: “{{ selfLink }}”

I get this error:

Fatal: [localhost]: FAILED! => {“changed”: false, “msg”: “GCP returned error: {‘error’: {‘errors’: [{‘domain’: ‘global’, ‘reason’: ‘invalid’, ‘message’: ‘Invalid value for field \‘resource.networkInterfaces[0]\’: \’{ "network": "https://www.googleapis.com/compute/v1/projects//global/networks/…\‘. Subnetwork should be specified for custom subnetmode network’}], ‘code’: 400, ‘message’: ‘Invalid value for field \‘resource.networkInterfaces[0]\’: \’{ "network": "https://www.googleapis.com/compute/v1/projects/sap-shared-vpn/global/networks/vpc-ott…\‘. Subnetwork should be specified for custom subnetmode network’}}”}

When I make this call for the network:

network_interfaces:

  • network_ip: “{{ ipaddress.address }}”
  • subnetwork: “{{ selfLink }}”

I get this error:

fatal: [localhost]: FAILED! => {“changed”: false, “msg”: “GCP returned error: {‘error’: {‘errors’: [{‘domain’: ‘global’, ‘reason’: ‘invalid’, ‘message’: "Invalid value for field ‘resource.networkInterfaces[0].network’: ‘’. The referenced network resource cannot be found."}], ‘code’: 400, ‘message’: "Invalid value for field ‘resource.networkInterfaces[0].network’: ‘’. The referenced network resource cannot be found."}}”}

What am I doing wrong? I am grateful for any help.

If I specify only the subnetwork value, then the server is assigned an IP address:

network_interfaces:

  • subnetwork: “{{ selfLink }}”

Sorry, found it:

network_interfaces:

  • network_ip: “{{ ipaddress.address }}”
  • subnetwork: “{{ selfLink }}”

is wrong

network_interfaces:

  • subnetwork: “{{ selfLink }}”

network_ip: “{{ ipaddress.address }}”

is right. My fault.

Following resolved the issue for me,

network_interfaces:

  • subnetwork:
    selfLink: “{{ subnet.resources[0].selfLink }}”
    Note: i have created register:subnet to gcp_compute_subnetwork_info.
