Driver vagrant does not provide a schema.

[zerchevack]

Hello,

I try to run a simple molecule test but the creation fail with the bellow output
I think the vagrant instance is not create and this is the reason of ansible failed but i don't know why the "Create" playbook skip all tasks.

Could you you help me ?
Have you an idea ?

Hi,

You should set more things for your vagrant box on your molecule.yml file.

• Memory
• CPU
• Network and IP adresse configuration

For IP I use : 192.168.10.42 but chose apropriate one for your tests ;)

@apatard This is my Response to #175

So since the docker plugin does not yet provide schema like the vagrant my only options are:

1. Ignore until a schema is provided
2. learn what schema actually is and contribute to the project

Did I miss anything?

there's a 3rd option:

• create a venv
• install ansible/molecule/-plugins in it
• take the schema from I gave you and put it into your venv
• test to check if it's fine
• report here and if fine, I'll try to open a PR soon-ish

I got the same error as this issue is about and when I tried manually adding the json inside venv under vagrant/schema/driver.json it didn't pick it up. Looking around a in molecule delegated driver I conclude that a the following needed to be defined in end of driver.py:

    def schema_file(self):
        return os.path.join(os.path.dirname(__file__), "schema", "driver.json")

After adding it I do not get WARNING Driver vagrant does not provide a schema. anymore. I also tested to add something wrong to see the validation is actually working (notvalid: true) and seems fine since I got the following error:

CRITICAL Failed to validate ##REDACTED##/extensions/molecule/default/molecule.yml

["Additional properties are not allowed ('notvalid' was unexpected)"]
