vagrant - Could not resolve hostname instance

[magick93]

Hello

I'm trying to get molecule working with vagrant.

I've tried various examples, such as the following:

---
driver:
  name: vagrant
  provider:
    # Can be any supported provider (virtualbox, parallels, libvirt, etc)
    # Defaults to virtualbox
    name: libvirt
  # Run vagrant up with --provision.
  # Defaults to --no-provision)
  provision: no
  # vagrant-cachier configuration
  # Defaults to 'machine'
  # Any value different from 'machine' or 'box' will disable it
  cachier: machine
  # If set to false, set VAGRANT_NO_PARALLEL to '1'
  # Defaults to true
  parallel: true
  # vagrant box to use by default
  # Defaults to 'generic/alpine316'
  default_box: 'bento/ubuntu-22.04'
platforms:
  - name: instance
    # If specified, set host name to hostname, unless it's set to False and
    # the host name won't be set. In all other cases (including default) use
    # 'name' as host name.
    hostname: foo.bar.com
    # List of dictionaries mapped to `config.vm.network`
    interfaces:
      - auto_config: true
        network_name: private_network
        type: static
        ip: 192.168.10.42
    # List of raw Vagrant `config` options
    instance_raw_config_args:
      # use single quotes to avoid YAML parsing as dict due to ':'
      - 'vm.synced_folder ".", "/vagrant", type: "rsync"'
      # Run 'uname' a provisionning step **needs 'provision: true' to work**
      - 'vm.provision :shell, inline: "uname"'
    # Dictionary of `config` options. Note that string values need to be
    # explicitly enclosed in quotes.
    config_options:
      ssh.keep_alive: yes
      ssh.remote_user: 'vagrant'
      synced_folder: true
    box: bento/ubuntu-22.04
    # box_version: 32.20200422.0
    box_url:
    memory: 512
    cpus: 1
    # Dictionary of options passed to the provider
    provider_options:
      video_type: 'vga'
    # List of raw provider options
    provider_raw_config_args:
      - cpuset = '1-4,^3,6'

But I always get the following error:

TASK [Gather system info] ******************************************************
fatal: [instance]: UNREACHABLE! => 
{
   "changed": false, 
   "msg": "Failed to connect to the host via ssh: ssh: Could not resolve hostname instance: Name or service not known", 
   "unreachable": true
}

Ran into the same issue, just made it work.
For some reasons molecule init copies default playbooks for create, destroy, converge. Replace the files in your scenario with corresponding ones from src/molecule_plugins/vagrant/playbooks in this repo.

Also make sure you have all the necessary deps in your requirements.txt, pip install 'molecule-plugins[vagrant]' do not seem to work. These are the following:

pyyaml >= 5.1
python-vagrant == 1.0.0
selinux

Hope this helps!

Thanks, this does help.

I'm now getting the following errors:

ERROR! couldn't resolve module/action 'vagrant'. This often indicates a misspelling, missing collection, or incorrect module path.

The error appears to be in '/home/ubuntu/my-project/collections/ansible_collections/org/bigcat/extensions/molecule/kvm/destroy.yml': line 8, column 9, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

    tasks:
      - name: Destroy molecule instance(s)
        ^ here

Also make sure you have all the necessary deps in your requirements.txt

Can you be more explicit on what I should have?

If I dont have molecule-plugins installed I get CRITICAL Failed to find driver vagrant. Please ensure that the driver is correctly installed.

And, regardless of using 'molecule-plugins[vagrant]' and or python-vagrant I get the same error:

The error appears to be in '/home/ubuntu/my-project/collections/ansible_collections/org/bigcat/extensions/molecule/kvm/destroy.yml': line 8, column 9, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

    tasks:
      - name: Destroy molecule instance(s)
        ^ here

Clearly this is a problem with dependencies. But I cant figure out, or find any docs on, what exact dependencies I need.

pip install 'molecule-plugins[vagrant]' do not seem to work.

In what way?

$ python3 -m pip install --force-reinstall molecule-plugins[vagrant]
