I bet a rocket stove would do it, but you would need to protect the base of the canner from smoky build up, you’d also have to feed the fire.
So I wonder if a gas grill would work? I know some have extra burners for cooking stuff. Since we are all electric, I have been thinking about getting a gas BBQ just for a backup cooking source, but also something to use for canning outdoors in the summer heat.
Hubby is going to fire up a propane burner he’s got to do the water bath canning.
What I like about the electric waterbath is you can use it for soup/stew and as a steamer too.
We’ll see if I still think I need it this fall when I’m done with canning.

A rocket stove is the best emergency stove as it will burn hot using just twigs and it burns so hot there is little residue left.
However, if not talking emergency situation, being able to replace propane bottles, for cooking and canning outside, a gas grill with large propane bottles will work just fine.
I also have an outdoor oven that works just like your inside oven and it can use large propane bottles, too.
I also have an outdoor fireplace which takes wood, charcoal.
re: outdoor canning...
I use propane burners. I have one banjo cooker and one jet cooker. The banjo cooker is ~40k BTU and is perfect for the cookpot when doing salsa and stuff like that.
The jet cooker is ~100k BTU - I use that one for the water bath pot or pressure canner. It will boil water in no time.
