docker-compose build - ERRO Couldn't connect to Docker daemon

Boa noite, estou precisando de um ajuda. Não estou conseguindo rodar o docker-compose build do arquivo abaixo. Estou usando o Docker Quickstart Terminal.

version: "3"

services:
  appBackend:
    build: 
      dockerfile: ./appBackend.Dockerfile
      context: .
    image: danilogomes/appBackend
    container_name: appBackend
    ports:
      - "8080:3000"
    volumes:
      - .:/user/appBackend
    networks:
      - prod-network
    depends_on: 
      - "databaseSelfMade"

  databaseSelfMade:
    image: mysql:latest
    networks:
      - prod-network

networks:
  prod-network:
    driver: bridge

ERRO:
