redis镜像里没有找到redis的conf文件，你可以使用环境变量启动

docker run --name myredis -v /root/redis/data:/data -v   
/root/redis/conf/redis.conf:/etc/redis/redis.conf -d -p 6379:6379 redis redis-server

权限管理不再介绍
https://blog.csdn.net/sasafa/article/details/126222609
点击左上角repositories->create repository。选择创建docker(hosted)。

[root@vm ~]# docker login 192.168.1.11:6000
[root@vm ~]# docker tag busybox:latest 192.168.1.11:6000/busybox:v1
[root@vm ~]# docker push 192.168.1.11:6000/busybox:v1

访问http://192.168.1.11:8088/repository/localhost/看到busybox实验ok

使用docker-compose同时管理多个服务

只需要一行命令docker compose up -d，就可以启动一个包含后端项目、前端项目、数据库的完整服务。

拉取Nginx镜像部署

docker run -d -p 80:80 -v /fronted-demo2:/usr/share/nginx/html --name frontend-test nginx
docker exec -it frontend-test /bin/bash

在项目根目录下新建nginx/default.conf

server {
    listen  80;
    server_name  localhost;
    underscores_in_headers  on;
    root /home/frontend;
    location / {
      try_files $uri $uri/ @router;
      index index.html;
    }
    location @router {
      rewrite ^.*$ /index.html last;
    }

  app-web:
   driver: bridge

services:
  mysql:
    image: mariadb
    ports:
     - 3306:3306
    command: --default-authentication-plugin=mysql_native_password
    restart: always

     - MYSQL_ROOT_PASSWORD=123456
    volumes:
     - ./mysql/data:/var/lib/mysql
