Ansible“gcp_compute_instance”模块不会将外部 IP 分配给 VM 实例

Question

- name: Create Disk
  gcp_compute_disk:
    name: "{{app_name}}-disk"
    size_gb: 50
    source_image: "{{source_image}}"
    zone: "{{ gcp_zone }}"
    project: web-project
    auth_kind: "{{ gcp_cred_kind }}"
    state: present
  register: disk

- name: Reserve IP Address
  gcp_compute_address:
    name: "{{app_name}}-address"
    region: "{{region}}"
    project: vpc-project
    auth_kind: "{{ gcp_cred_kind }}"
    state: present
  register: address

- name: Create VM Instance
  gcp_compute_instance:
    name: "{{app_name}}-vm"
    machine_type: "{{instance_type}}"
    disks:
    - auto_delete: true
      boot: true
      source: "{{disk}}"
    network_interfaces:
    - subnetwork: 
        selfLink: "{{subnetwork}}"
        access_configs:
        - name: External NAT
          nat_ip: "{{ address }}"
          type: ONE_TO_ONE_NAT
    zone: "{{ gcp_zone }}"
    project: web-project
    auth_kind: "{{ gcp_cred_kind }}"
    state: present
  register: instance

The VPC exists in the "vpc-project" and is shared with "web-project", which has no.network of its own.

Region: us-west1 Zone: us-west1-b

When I run the code, it successfully creates the VM using the other projects VPC and assigns an internal IP to it.

However, it does NOT assign the external IP to it. I have confirmed that the address was created and in the correct region, but it's just sitting there unused.

Just for testing, I had it create an external address and a VM in the projects local.network but it still didn't assign the public address to it.

Am I missing something?

Answer 1

John and Ferregina were correct - an external IP from one project cannot be assigned to a resource in another project. I changed the playbook accordingly.

However that was not the cause of my pain. It was a playbook-related issue. Using the "selfLink" in the play was causing it to completely ignore the entire part about "access_configs" for some reason.

I changed it from this:

network_interfaces:
- subnetwork: 
    selfLink: "{{subnetwork}}"
    access_configs:
    - name: External NAT
      nat_ip: "{{ address }}"
      type: ONE_TO_ONE_NAT

To this:

network_interfaces:
- subnetwork: "{{subnetwork_info.resources[0]}}"
  access_configs:
  - name: External NAT
    nat_ip: "{{ external_address }}"
    type: ONE_TO_ONE_NAT

And it worked.
