Ruby Question

Unexpected error when Vagrant up using yaml file

I'm experimenting this issue using yaml

I was working fine using a yaml file that contains config to my Vagrantfile, after many changes (adding iterations in the Vagrantfile) the vagrant up fails unexpectedly showing an error

I tried get back an old commit that "worked" correctly, the error persist even when that code was worked.

I tried many options like:


  • vagrant up from scratch (removing .vagrant, boxes and vagrant.d)

  • uninstall and install vagrant



I decided to remove the yaml file and its references and the vagrant up worked again. Finally

For any reason vagrant shows this error related to ruby trying to convert to an array.

Any Idea?




my setup


  • mac: OS X Yosemite, version 10.10.5

  • vagrant: 1.8.1

  • ruby: 2.0.0p481

  • docker host: hashicorp/boot2docker






my Vagrantfile

require 'yaml'
config = YAML.load_file('develop.yaml')
Vagrant.configure("2") do |config|
config.vm.define "machine1" do |a|
a.vm.provider "docker" do |d|
d.image = config["image"]
... more





my develop.yaml

---
image: "registry/user/image:xx"
... more

Answer

Inside the Vagrant.configure("2") block, you overwrite your config variable with the block argument of the same name. Thus, inside the block, config refers to the vagrant configuration object instead of the parsed YAML hash.

If you refer to the YAML hash with another name, e.g.

yaml_config = YAML.load_file('develop.yaml')

you can access the various objects unambiguously.
