Is it possible to validate that a boolean is true using Joi? I've tried using allow, valid and invalid without any luck.

Have you tried something like this:
var schema = Joi.boolean().invalid(false);
Using that schema, the following all populate the error property:
Joi.validate(false, schema);
Joi.validate('false', schema);
Joi.validate('no', schema);
Joi.validate('off', schema);
Joi.validate(0, schema);
