   I think you have 2 options:

   1. Manually parse the arbritray args yourself, using a -- seperator.
   2. Add an option to the task.

   @task
   def example1(c):
       rest_args = sys.argv[sys.argv.index("--") + 1 :] if "--" in sys.argv else []
       print("rest_args = {}".format(rest_args))
       # use shlex.join() if you're on Python 3.8
       c.run(
           "docker run -it myapp {}".format(" ".join([shlex.quote(x) for x in rest_args]))
       )
   
   
   @task
   def example2(c, docker_args=""):
       print("docker_args = {!r}".format(docker_args))
       c.run("docker run -it myapp {}".format(docker_args))

   $ inv --dry --echo example1 -- a b "c with spaces"
   rest_args = ['a', 'b', 'c with spaces']
   docker run -it myapp a b 'c with spaces'
   
   $ inv --dry --echo example2 --docker-args 'a b "c with spaces"'
   docker_args = 'a b "c with spaces"'
   docker run -it myapp a b "c with spaces"

   The parser appears to support accessing the remainder args, however I'm unsure how to access that property.
