ansible gcp_compute_instance - 在创建 vm 实例时附加现有的外部 ip 地址

Question

I want to attach an existing (created before) external ip address when creating vm instance:

• create address

- name: create address
  gcp_compute_address:
    name: my-external-ip
    region: europe-west1
    address_type: '{{ item.compute_address_type | default("EXTERNAL") }}'
    network_tier: "{{ item.compute_address_network_tier | default("PREMIUM") }}"
    project: "{{ gcp.project_id }}"
    auth_kind: serviceaccount
    service_account_file: "{{ gcp.credentials_file }}"
    state: present
  with_items: "{{ compute_address }}"
  register: address
  tags: create_address

• create instance

- name: create compute instances
  gcp_compute_instance:
    name: my-instance
    zone: europe-west1-b
    machine_type: "{{ item.instance_type }}"
    metadata: "{{ item.instance_metadata | default(omit) }}"
    labels: "{{ item.instance_label | default(omit) }}"
    tags: "{{ item.instance_tags | default(omit) }}"
    scopes: '{{ item.instance_scopes | default("https://www.googleapis.com/auth/cloud-platform") }}'
    disks: "{{ item.disks }}"
    network_interfaces: "{{ item.network_interfaces }}"
    project: "{{ gcp.project_id }}"
    auth_kind: serviceaccount
    service_account_file: "{{ gcp.credentials_file }}"
    state: present
  with_items: "{{ instances }}"
  register: instance
  tags:
 - create_instance

• vars for network_interfaces

instances:
  network_interfaces:
 - network:
      name: default
    access_configs:
    - name: External NAT
      nat_ip:
        address: projects/project_id/regions/europe-west1/addresses/my-external-ip
      type: ONE_TO_ONE_NAT

• The address has been created:

$ gcloud compute addresses describe my-external-ip --region europe-west1
address: 35.X.Y.Z
addressType: EXTERNAL
creationTimestamp: '2020-07-24T03:10:44.048-07:00'
description: ''
id: '1804649404875345227'
kind: compute#address
name: my-external-ip
networkTier: PREMIUM
region: https://www.googleapis.com/compute/v1/projects/project_id/regions/europe-west1
selfLink: https://www.googleapis.com/compute/v1/projects/project_id/regions/europe-west1/addresses/my-external-ip
status: RESERVED

Then I run, there's an error:

'message': "Invalid value for field 'resource.networkInterfaces[0].accessConfigs[0].natIP':
'projects/neoevolution/regions/europe-west1/addresses/neoevolution-dev-eip-1'. 
The specified external IP address 
'projects/neoevolution/regions/europe-west1/addresses/neoevolution-dev-eip-1' 
was not found in region 'europe-west1'

THANKS FOR YOUR HELP, PEACE.

Answer 1

Check if your external reserved IP looks good(belong the correct region etc.):

gcloud compute addresses list
NAME            ADDRESS/RANGE   TYPE      PURPOSE  NETWORK  REGION        SUBNET  STATUS
my-external-ip  35.207.102.185  EXTERNAL                    europe-west3          RESERVED

Try to reference the IP by the address itself rather than the name. I reproduced in a simple deployment and this worked for me:

 "accessConfigs": [ { "kind": "compute#accessConfig", "name": "External NAT", "type": "ONE_TO_ONE_NAT", "natIP": "35.207.102.185", "networkTier": "STANDARD" } ]

And of course make sure you are referencing your network variables correctly. You may try to hard-code the values to narrow down the possible source of the problem.

Peace; ;)
