最近在测试环境用 docker-compse 创建了一个 redis 容器，结果远程无法访问；但是手动(docker命令)创建的就没问题（使用 redis 客户端连接测试过），感觉见鬼了，下面是 docker-compose.yaml：
version: '3'
services:
redis:
image: redis
container_name: t_redis
privileged: true
volumes:
- /home/opensearch/redis/data:/data
- /home/opensearch/redis/conf/redis.conf:/usr/local/etc/redis/redis.conf
- ./logs/redis-server.log:/usr/local/etc/redis/logs/redis-server.log
command: redis-server /usr/local/etc/redis/redis.conf --save 60 1
ports:
- 6379:6379创建完之后的效果：
[root@localhost redis]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4585b293e57a redis "docker-entrypoint..." 2 minutes ago Up 2 minutes 0.0.0.0:6379->6379/tcp t_redis
d2e2bd273f83 redis "docker-entrypoint..." 2 hours ago Up 2 hours 0.0.0.0:6380->6379/tcp mrd（其中 mrd 是手动创建的，t_redis 是 docker-compose 创建的）
下面是 docker inspect t_redis的结果：

感觉 NetworkSettings 这里似乎有问题，但是不确定，也不知道如何解决
（看网上的和之前的的 compose 文件配置项也大都是如此... 想不明白这次为啥就不行了）
补充说明：
防火墙没开，IPtables 没装
[root@localhost ~]# iptables
iptables v1.4.21: no command specified
Try `iptables -h' or 'iptables --help' for more information.
[root@localhost ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)
[root@localhost ~]#上面已经提过了手动创建是可以远程访问的，而且我把手动创建的关掉，docker-compose中用6380 照样无法访问，所以端口和防护墙的原因应该是可以排除的
应该和docker自身没有关系，没记错的话，
redis的配置文件默认监听的时127.0.0.1吧，你看下你redis.conf里面的bind时什么地址，是127.0.0.1的话 改成0.0.0.0重启下。
