Packer: Build 'amazon-ebs' errored

[alexkappa]

Hello,

I'm trying to build the following image and I get an error that I don't know how to debug. Could you please point me to what I'm doing wrong?

I get an Build 'amazon-ebs' errored: Process exited with: 1. Reason was: () error message.

Packer version is v0.8.6.

{
  "builders": [
    {
      "type": "amazon-ebs",
      "region": "eu-west-1",
      "ami_name": "My-CoreOS-835.9.0",
      "source_ami": "ami-c26bcab1",
      "instance_type": "m3.medium",
      "ssh_username": "core"
    }
  ],
  "provisioners": [
    {
      "type": "file",
      "source": "bin/",
      "destination": "/usr/bin"
    }
  ]
}

Running packer with the -debug flag gives me the following output:

$ packer build -debug packer.json                                                                                                                                                                                                                [9:25:08]

Skip the --debug flag and run with env PACKER_LOG=1.

e.g.

PACKER_LOG=1 packer build packer.json

Gist the log. See http://packer.io/docs/other/debugging.html

The scp fails, did you try to add a slash to the destination?

The trailing slash didn't do it. After some digging I found that /usr is read-only on CoreOS so that was probably what caused the error.

I worked around this by uploading a gzipped folder and extracting it on the destination using the shell provisioner (also used /opt/bin instead which is not write protected).

It's not a huge problem but an error message would be very helpful here. If you think its not worth pursuing I can close this issue.

Just in case anyone is interested this is how the packer template looks like now:

{
  ...
  "provisioners": [
    {
      "type": "file",
      "source": "bin.tar.gz",
      "destination": "/tmp/bin.tar.gz"
    },
    {
      "type": "shell",
      "inline": [
        "sudo mkdir -p /opt",
        "sudo tar -xvf /tmp/bin.tar.gz -C /opt",
        "sudo chmod +x -R /opt/bin"
      ]
    }
  ]
}

Thanks for the report, I think we can improve the error feedback here.
