# 镜像加速 #

从镜像加速地址进行拉取有三种方式

1，在命令中指定镜像地址

$ docker pull registry.docker-cn.com/myname/myrepo:mytag

2，配置 Docker 守护进程默认使用 Docker 官方镜像加速，无需在每次拉取时指定 registry.docker-cn.com

$ docker --registry-mirror=https://registry.docker-cn.com daemon

3，永久保留配置，重启服务仍有效

vi /etc/docker/daemon.json
    {
      "registry-mirrors": ["https://registry.docker-cn.com"]
    }
    service docker restart   #一定要重启docker服务,配置才会生效

**docker 安装 mysql 8 版本**

# docker 中下载 mysql
    docker pull mysql
    
    #启动
    docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=Qwer123! -d mysql
    
    #进入容器
    docker exec -it mysql bash
    
    #登录mysql
    mysql -u root -p
    ALTER USER 'root'@'localhost' IDENTIFIED BY 'Qwer123!';
    
    #添加远程登录用户
    CREATE USER 'wender'@'%' IDENTIFIED WITH mysql_native_password BY 'Qwer123!';
    GRANT ALL PRIVILEGES ON *.* TO 'wender'@'%';

#  进入容器，执行linux命令，查看目录结构 #

[root@s01 ~]# docker ps -l
    CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

# 上传镜像 #

docker注册，可能需要番羽过去，有好多图文交互的验证。

"docker tag" requires exactly 2 arguments.
    See 'docker tag --help'.
    
    Usage:  docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]
    
    Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE
    [root@s01 ~]# docker tag fhbean/dockertest fhbean/dockertest:1.0
    [root@s01 ~]# docker push fhbean/dockertest:1.0
    The push refers to repository [docker.io/fhbean/dockertest]
