我可以列出所有容器docker ps (-a),我可以列出所有卷docker volumes ls,当我检查一下时volume,我可以看到name,driver而且mountpoint,而不是它正在使用的容器.

当我使用时docker inspect <container>,我可以看到像这样的Mount数据,例如:

"Mounts": [
    {
        "Name": "centos_db_symfony",
        "Source": "/var/lib/docker/volumes/centos_db_symfony/_data",
        "Destination": "/var/lib/mysql",
        "Driver": "local",
        "Mode": "rw",
        "RW": true,
        "Propagation": "rprivate"
    },

所以从理论上讲,我可以编写一个循环遍历所有容器的脚本来匹配特定volume的名称.但是我运行了一些容器docker-compose,并没有将某个名称(就像现在可能在v2中)绑定到某些卷,因此它们在docker volume ls列表中显示为sha256 ,如下所示:

DRIVER              VOLUME NAME
local               34009871ded5936bae81197247746b708c3ec9e9b9832b702c09736a90...etc
local               centos_data
local               centos_db_symfony

在这种情况下34009871ded5(示例)是在我之前docker-compose和centos_db_symfony之后命名卷之前创建的.

题

当docker-compose.yml更新卷信息时,就像在这种情况下更新命名卷和信息一样,docker inspect <container>历史记录是否永远丢失,或者我可以找出卷使用哪个容器？如果是这样,是否还可以恢复这样的旧卷？

I am trying to build a coupon site in Laravel. Each merchant has their own deals/coupons. I have been able to print deals/coupons for a merchant on their specific pages.

Here's my query

$deals = DB::table('deals')
    -> join ('merchants', 'deals.merchant_id', '=', 'merchants.merchant_id')
    -> where ('merchant_url_text', $merchant_url_text)
    -> get();

So far so good.

Now this is where it starts getting complex.

Each deal has 2 more pieces associated with it. Click counts and Votes associated with deals.

The click counts are …

每当我试图使用\Auth::User()我得到非对象属性,因为Auth::guest()无论何时我在服务提供商中使用它都返回true

use Illuminate\Contracts\View\View;
use Illuminate\Support\ServiceProvider;
use Illuminate\Contracts\View\Factory;
use App\relations;
use App\User;
use DB;
use Illuminate\Support\Facades\Auth;

class RelationServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
        \Auth::User()->id;

        $relation_friend_for_logged_user = DB::select( DB::raw("SELECT * FROM users"));

        $value = "asd";

        // for injecting objct
        View()->share('count', $value);
    }

但是,\Auth::guest()无论我是否登录,为什么返回true
