How to install tcp cardano node testnet on docker

Developers Cardano Integration

Hi all,
I want to install cardano node testnet on docker and public it through port 3001 so my app with cardano-cli can connect to it and query data. So this is a producer node or relay node ?
Here my docker-compose

version: '3.1'

services:
  cardano-node:
    image: inputoutput/cardano-node:1.35.5
    container_name: cardano-node
    volumes:
      - ./cardano-node-ipc:/ipc # socket path
      - ./cardano-node-data:/data
      #- ./configuration:/configuration
      - ./config:/config
      - ./cardano-wallet:/cardano-wallet # cardano-cli path
    environment:
      - TZ=Asia/Ho_Chi_Minh
      - CARDANO_NODE_SOCKET_PATH=/ipc/node.socket
      - CARDANO_CLI=/cardano-wallet/cardano-cli
      - TESTNET_MAGIC=1
      - DOCKER_CLIENT_TIMEOUT=120
      - COMPOSE_HTTP_TIMEOUT=120
      - NETWORK=preprod
    ports:
      - "3001:3001"
    restart: unless-stopped
    networks:
      - cardano-node-net

networks:
  cardano-node-net:
    name: cardano-node-net
    driver: bridge

Content of “config” folder (I downloaded below files from /environments/preprod/)

ls config/
alonzo-genesis.json  byron-genesis.json  config.json  db-sync-config.json  shelley-genesis.json  submit-api-config.json  topology.json

#topology.json
{
  "LocalRoots": {
    "groups": [
      {
        "localRoots": {
          "accessPoints": [],
          "advertise": false
        },
        "valency": 1
      }
    ]
  },
  "PublicRoots": [
    {
      "publicRoots": {
        "accessPoints": [
          {
            "address": "preprod-node.world.dev.cardano.org",
            "port": 30000
          }
        ],
        "advertise": false
      }
    }
  ],
  "useLedgerAfterSlot": 4642000
}

And my cardano node only run on unix sock.

As I read from GitHub - input-output-hk/cardano-node: The core component that is used to participate in a Cardano decentralised blockchain.
I will need folder “configuration” with 3 files : configuration.yaml , genesis.json , topology.json
Where can I download these files ?
How should I config these files so my cardano node listen on tcp port 3001 and accept connection from remote cardano-cli ?
