Hi all,
I am struggling to run serverspec test on GCP packer instance from local
machine.
I have created a packer json config file as follows to create an image on
GCP (provisioners run shell script to create an user account for sftp on
packer instance):
{
"variables": {
"project": "gcp-project",
"image_family": "centos-7",
"username": "centos",
"sftp_username": "",
"sftp_password":"",
"zone": "us-central1-c",
"version": "latest"
},
"builders": [
{
"type": "googlecompute",
"account_file": "account.json",
"project_id": "{{user `project`}}",
"zone": "{{user `zone`}}",
"source_image":"centos-7-v20171025",
"image_name": "sftp-{{user `image_family`}}-{{user
`version`}}-{{timestamp}}",
"image_family": "{{user `image_family`}}",
"image_description": "sftp - from packer",
"ssh_username": "{{user `username`}}",
"machine_type": "g1-small"
}
],
"provisioners": [
{
"type" : "shell",
"inline": [
"sudo adduser {{user `sftp_username`}}",
"sudo echo -e '{{user `sftp_password`}}\n{{user
`sftp_password`}}\n' | sudo passwd {{user `sftp_username`}}",
"sudo mkdir -p /var/sftp/upload",
"sudo chown root:root /var/sftp",
"sudo chmod 755 /var/sftp",
"sudo chown {{user `sftp_username`}}:{{user
`sftp_username`}} /var/sftp/upload"
]
},
{
"type": "shell-local",
"command": "rake spec TARGET_HOST=remotehost"
}
]
}
and i am executing rake spec TARGET_HOST=(ip of packer instance) to run
serverspec test from local machine and spec_helper.rb is configured with
ssh login as follows:
host = ENV['TARGET_HOST']
options = Net::SSH::Config.for(host)
options[:user] = 'centos'
set :host, options[:host_name] || host
set :ssh_options, options
and Rakefile is configured to run test from specific folder.
after running packer build command "packer build -var-file=variables.json
sftp.json| tee build.log"
it fails with
Net::SSH::AuthenticationFailed:
Authentication failed for user [email protected]

I am not able to ssh to this temporary packer instance and serverspec test
fail to run.
any answer will be appreciated. thanks very much.
