How do you produce a near vacuum with a hole on one end?

  By extending the cannon's end to space.

    Oh no, now the vacuum of space is leaking into the base of a mountain!

      What if it leaks out to sea level and kills us all?

  Can't you do something similar to what the engineers in the rocket throwing video are doing?

  A door.

  Presumably with a rapidly opening door. Of course now you have to design your rocket to slam into an atmosphere at launch velocity. You might have to install enormous compressed air tanks at the end to pre-accelerate the air right as the door opens just to make it less like hitting a brick wall of onrushing air.
