Googlecompute: Timeout waiting for SSH

I am trying to create the image on GCP and finding the SSH timeout error while building the image with Packer.

googlecompute: output will be in this color.

Hello there, do you have a buildfile for this one ?

Hello azr,

No, I don’t have buildfile for this.

What Azr means is, we need to see your packer template and preseed files, not just the logs, if you want help troubleshooting this.

I am running into this. I have tried the same thing with a few different Debian and Ubuntu images. The builder part of my config is:

“builders”: [
“type”: “googlecompute”,
“account_file”: “project-info.json”,
“project_id”: “private…”,
“source_image”: “ubuntu-minimal-2010-groovy-v20210113”,
“disk_size”: “30”,
“machine_type”: “f1-micro”,
“ssh_username”: “packer”,
“zone”: “us-central1-a”,
“image_description”: “packer image for generic web server”,
“preemptible”: true

Any pointers appreciated. I set this up a long time ago, forgot everything about Packer, and now I don’t want to get caught in a jam.


Interesting finding on this: if I run Packer with -debug, and take my time between the key steps (I assume the ones between creating the instance and connecting via ssh), it works. If I just let packer build run, it fails every time.

My problem was fixed by adding the following to the builder json:

  "wait_to_add_ssh_keys": "20s",

It gave things enough time to catch up.

Thank you tomdotorg!

It works for me as well :blush:
