docker centos 容器启动后停止问题解决

背景

docker-compose up -d 发现容器启动后又停止

关键配置

tty: true
模拟一个伪终端，阻止容器退出

docker-compose.yml

[root@test centos]# cat docker-compose.yml 
version: "3"

services:
    centos:
        image: centos:7.5.1804
        build:
            context: /ROOT/docker/dockerfile
            dockerfile: centos
        volumes:
            - "/ROOT:/ROOT"
        container_name: web-server
        restart: always
        hostname: web-server
        tty: true
