Failed to create a droplet and apply a firewall #302

Open katefike opened 1 year ago

katefike commented 1 year ago
SUMMARY

In my ansible playbook I create a firewall and it's successful. Then I create a droplet and apply the firewall to it, but it fails without a message. In Digital Ocean the droplet exists and is correctly configured with the firewall applied.

OS / ENVIRONMENT
STEPS TO REPRODUCE

My ansible playbook:

- hosts: localhost
  vars:
    digital_ocean_token: '{{ lookup("env", "DO_API_TOKEN") }}'
    droplet_size: s-1vcpu-1gb
    droplet_region: nyc1
    droplet_image: ubuntu-22-04-x64
  tasks:
  - name: Create firewall named "sage.test"
    community.digitalocean.digital_ocean_firewall:
      name: "sage.test"
      inbound_rules:
        - protocol: "tcp"
          ports: "22"
          sources:
            addresses: ["0.0.0.0/0", "::/0"]
      outbound_rules: 
        - protocol: "tcp"
          ports: "587"
          destinations:
            addresses: ["0.0.0.0/0", "::/0"]

  - name: Create a new Droplet
    digital_ocean_droplet:
      name: sage.prod
      oauth_token: "{{ digital_ocean_token }}"
      size: "{{ droplet_size }}"
      region: "{{ droplet_region }}"
      image: "{{ droplet_image }}"
      firewall: ['sage.test']
      wait_timeout: 600
      unique_name: yes
      state: present
    with_inventory_hostnames:
      - web
    register: droplet_result
EXPECTED RESULTS

I expect that either: a. If there is an "ok" response, then the droplet has been created with the firewall applied to it. b. If there is a "failed" response, then the droplet has not been created and there is an error message.

ACTUAL RESULTS

Command:

exec ansible-playbook -i inventory_prod.yml create_droplet_prod.yml --ask-become-pass -vvvv

In Digital Ocean in the droplet's "Networking" page I can see that this firewall was applied. image

@katefike

In my ansible playbook I create a firewall and it's successful. Then I create a droplet and apply the firewall to it, but it fails without a message. In Digital Ocean the droplet exists and is correctly configured with the firewall applied.

I don't quite get it, can you clarify whether ...

  1. firewall and droplet are created. Firewall is applied to droplet, but it does not show in the ansible execution, or
  2. firewall and droplet are created. Firewall is NOT applied to droplet
damex commented 7 months ago

firewall and droplet are created. Firewall is applied to droplet, but it does not show in the ansible execution, or

maybe this one? droplet is created and firewall is applied but task always returns failed condition. should be changed but returns changed: false

i tested latest ansible + digitalocean community collection and if i specify firewall during droplet creation - droplet creation task always endups in failure. if i omit firewall definition - task gets proper changed state and consequent runs with firewall definition work as expected.

all fails have

 "msg": [
        null,
        true
    ]

all consequent and/or successful runs does not have msg [ null, true ] in them.

does not matter if it is a string or array or firewalls (should be array of strings according to manual) it still fails.

to test just use simple droplet creation and specify firewall. it will always fail if droplet gonna be created for the first time.

damex commented 7 months ago

this is failed variant. just specified smallest droplet they offer and runned with firewall option. it failed and returned changed: false. it succeeds without firewall as explained above. returned message that ansible considers a failure:
