Inventory generator is not working. #4

Open jeka opened 5 years ago

jeka commented 5 years ago

Hello, at last, I have little time to play a bit more with this generator. First, sorry for the vague description, but I have no idea how to describe it better.

So, I have a case where nbering's python version of inventory generator works and this one fails. python version:

$ ../../terraform.py --list                    
{
  "all": {
    "hosts": [
      "master-01",
      "worker-01"
    ],
    "vars": {},
    "children": []
  },
  "_meta": {
    "hostvars": {
      "master-01": {
        "ansible_host": "10.164.136.39",
        "ansible_user": "centos"
      },
      "worker-01": {
        "ansible_host": "10.164.133.190",
        "ansible_user": "centos"
      }
    }
  },
  "bootstrap": {
    "hosts": [
      "master-01",
      "worker-01"
    ],
    "vars": {},
    "children": []
  },
  "k8s-master": {
    "hosts": [
      "master-01"
    ],
    "vars": {},
    "children": []
  },
  "k8s-worker": {
    "hosts": [
      "worker-01"
    ],
    "vars": {},
    "children": []
  }
}

Go version:

$ ../../ansible-terraform-inventory-linux-amd64 --list
{"_meta":{"hostvars":{}}}

I suspect that data source 'local_file' is confusing your generator. I added a line

if err != nil {
        return nil, fmt.Errorf("Error unmarshaling state: %s\n", err)
    }
+   fmt.Printf("%+v\n", s)
    return &s, nil
}

and the resulting output is:

I can provide more information if needed.

@jeka I'm so sorry for the late reply. I finally had some time to look into this. I added a local_file data source to the test fixtures, but that didn't recreate the problem you're seeing, so it must be something else.

Would it be possible to get a sanitized version of your entire terraform.tfstate file?

jtopjian commented 5 years ago

@jeka Actually, I might have found the cause: It appears that you are not explicitly declaring any ansible_group resources?

You have ansible_host resources which declare groups and I suppose that we could generate groups based on this implicit group membership.

jeka commented 5 years ago

@jtopjian You are right, I am not declaring ansible_group resources. As this is a part of an 'instance' module and I am assigning groups on invocation, i. e.:

resource "ansible_host" "host" {
  inventory_hostname = "${openstack_compute_instance_v2.this.*.name[count.index]}"
  groups             = "${var.ansible_groups}"

  vars {
    ansible_user = "${var.ssh_user}"
    ansible_host = "${openstack_networking_floatingip_v2.fip.*.address[count.index]}"
  }
}
jtopjian commented 5 years ago

@jeka Thanks for the info and for reporting this. I think this is now fixed and you can try it out in the latest release (https://github.com/jtopjian/ansible-terraform-inventory/releases/tag/v0.2.0). Let me know if you're still having problems, though.
