"It's over," Bexar County Sheriff's office spokesman James Keith said, adding that deputies were still on the scene.
The sheriff's office had responded to reports of a shooter at the base.The Federal Bureau of Investigation said it had been called to assist.
Parts of the base were locked down as a result of the incident, including three schools, the sheriff's office said. Military police and sheriff's deputies were dispatched to clear out buildings.
Authorities also ordered people at a nearby industrial complex to stay in their buildings.
