Building a rocketmq cluster with docker-compose, managing which broker is in control

Question

I want build a rocketmq cluster on my machine, where the mode is master-slave, with docker-compose

And I can only start one broker at the same time. That say when I start master, slave exits. The opposite is also, can some body help?

Here is my docker-compose.yml

version: '2'
services:
  namesrv:
    image: rocketmqinc/rocketmq:4.5.0-alpine
    ports:
      - 9876:9876
    volumes:
      - "/data/namesrv/master/logs:/opt/logs"
      - "/data/namesrv/master/store:/opt/store"
    environment:
      MAX_POSSIBLE_HEAP: 100000000
    command: sh mqnamesrv
  broker-a-m:
    image: rocketmqinc/rocketmq:4.5.0-alpine
    ports:
      - 10909:10909
      - 10911:10911
    volumes:
      - "/data/broker-a/logs:/opt/logs"
      - "/data/broker-a/store:/opt/store"
      - "/data/broker-a/conf:/opt/conf"
    links:
      - namesrv:namesrv
    environment:
      NAMESRV_ADDR: namesrv:9876
    command: sh mqbroker -c /opt/conf/broker.conf
  broker-a-s:
    image: rocketmqinc/rocketmq:4.5.0-alpine
    ports:
      - 11909:10909
      - 11911:10911
    volumes:
      - "/data/broker-a-slave/logs:/opt/logs"
      - "/data/broker-a-slave/store:/opt/store"
      - "/data/broker-a-slave/conf:/opt/conf"
    links:
      - namesrv:namesrv
    environment:
      NAMESRV_ADDR: namesrv:9876
    command: sh mqbroker -c /opt/conf/broker.conf

slave broker conf

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 1
deleteWhen = 04
fileReservedTime = 48
listenPort = 10911

brokerRole = SLAVE
flushDiskType = ASYNC_FLUSH

slave broker conf

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
listenPort = 10911
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

when broker slave starts, the master writes the log and exits;
