docker容器启动时，就自动退出了，求解决方案

Question

这个是Dockerfile

FROM daocloud.io/library/nginx:1.13.5-alpine
RUN apk update $$ apk upgrade
RUN apk add --no-cache bash curl ipvsadm iproute2 openrc keepalived
COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh
CMD ["/entrypoint.sh","/bin/bash"]

这个是entrypoint.sh

#!/bin/sh

#/usr/sbin/keepalvined -n -l -D -f /etc/keepalived/keepalived.conf --dont-fork --log-console &
/usr/sbin/keepalived -D -f /etc/keepalived/keepalived.conf 


nginx -g "daemon off;" 

docker-compose

version: "3.1"
services:
  nginx_master:
    build:
      context: ./
      dockerfile: ./Dockerfile

    networks:

    cap_add:

  proxy:

    volumes:
      - ./haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg
    networks:
      - static-network

networks:
  static-network:
    ipam:
      config:
        - subnet: 172.20.0.0/16

不知道哪里的问题 网上找了说要在Dockerfile或者.sh里加一个死循环让他前台运行，但具体还是不知道怎么解决，有没有大佬指导一下
