Openstack builder connects to wrong endpoint

[JoelFeiner]

I am attempting to build an image using the OpenStack provider. It ultimately fails at launching the server with the following message: "Error launching source server: Invalid request due to incorrect syntax or missing required parameters".

It is able to connect to the identity service, verify the flavor and set up the keypair (which might be a local thing).

One thing I am noticing is that tcpdump shows a lot of connections to ec2-54-235-77-197.compute-1.amazonaws.com, whereas when I launch the server with the nova client, there are none. I'm wondering if there's a hardcoded URL in Packer somewhere.

I'm unable to further debug this because Packer or the underlying library does not provide the response from the OpenStack server. From Googling, I see that this is simply not supported at the current juncture.

Packer 1.0.3
Ubuntu 17.04 64-bit
Build output: https://gist.github.com/JoelFeiner/7f7102e3324e4efc00980600217a07aa

Builder config in JSON file:

        {
            "type": "openstack",
            "flavor": "A1.2",
            "source_image": "7925b8a6-b439-4991-9adf-092a202ff16e",
            "ssh_username": "root",
            "networks": [ "bf7a7067-8739-4421-9a08-c940d7fd435d" ],
            "image_name": "{{user `image_type`}}-{{user `image_verson`}}"
        }

Environment variables set:
OS_AUTH_URL
OS_REGION_NAME
OS_IDENTITY_API_VERSION
OS_TENANT_NAME
OS_PASSWORD
OS_USERNAME

If you can post the info required to reproduce this, we might be able to take a look. However, I suspect the mailing list might be a better place to ask for help.

hard to say what this connection is without seeing your scripts, but I'm certain this is a node that's launched as part of the build

I don't know what I can post that would allow you to reproduce, as you do not have access to our cloud provider and it would not be prudent to share that information. What would be great is some way of getting better output from Packer about why the call failed. If you know of a way to do that, that could make a huge difference. As far as I can tell, that's the only way we can get to something of a repro out of this.

I am not using any Amazon cloud services, but rather an entirely different provider. And as I said in the original message, tcpdump running while using the nova client does not show connections to the Amazon addresses. It could be spurious, but it's concerning.

oh, I see, I think that's https://checkpoint.hashicorp.com/ you can disable by setting `CHECKPOINT_DISABLE=1`

Just a minor thing, in your OpenStack you use flavor A1.2 but then you run:

openstack flavor show A1.1

[JoelFeiner]

I switched to using A1.1 so that the image can be used for A1.1 instances, as well as the higher level ones. The only difference is that A1.1 has half as many CPUs, half as much RAM and half as much hard-drive space as A1.2. It's not relevant to this issue.
