Originating out of ZZZ; my aircraft had frost on its wings. We proceeded normally to the deicing location. Upon completion of deicing the Captain's wing and as the deicing truck started to back up to move around the wingtip; the entire aft end of the truck became engulfed in flames! A raging fire started on the back end of the truck where the deicing fluid was held. We did not complete the Post Deice Checklist prior to moving the aircraft to safety. My concern was the truck exploding close to the aircraft and its passengers. We taxied the aircraft away from the burning vehicle. I thought it was the safest course of action to move the aircraft quickly out of the danger area. Once in a safe location; I stopped the aircraft; set the brakes; and completed the necessary checklists. Rest of flight was uneventful.
Air carrier Captain reported that the de-icing truck caught fire while repositioning.
