如何连接memcached laravel和docker

Question

我已经在docker中创建了memcached容器docker-compose.yml:

#store cache
memcached:
image: memcached
container_name: memcached
ports:
- "11211:11211"

.env

MEMCACHED_HOST=memcached
MEMCACHED_PORT=11211
CACHE_DRIVER=memcached

并且在我的CCD_ 1文件部分CCD_

'memcached' => [
'driver' => 'memcached',
'persistent_id' => env('MEMCACHED_PERSISTENT_ID'),
'sasl' => [
env('MEMCACHED_USERNAME'),
env('MEMCACHED_PASSWORD'),
],
'options' => [
// Memcached::OPT_CONNECT_TIMEOUT  => 2000,
],
'servers' => [
[
'host' => env('MEMCACHED_HOST', '127.0.0.1'),
'port' => env('MEMCACHED_PORT', 11211),
'weight' => 100,
],
],
],

在一个方法中，我做了以下例子：

$user = Cache::remember('user', 60, function() {
return AppModelsUser::first();
}); */
$c = new Memcached();
$c->addServer("memcached", 11211);
var_dump( $c->getAllKeys() );

但我得到了错误：

Error: Class 'Memcached' not found 

我不知道这是否是我的容器中的问题，因为当我用以下命令进入容器时：

docker-compose exec --user 0 memcached bash 

我在容器中运行了stats命令，但我得到了一个错误，即没有找到

root@520aaa151216:/# stats
bash: stats: command not found

我已执行：

php artisan cache:clear
composer dump-autoload 

但是memcached错误仍在继续。

在此链接中找到：https://github.com/devilbox/docker-php-fpm/blob/master/Dockerfiles/mods/Dockerfile-7.3

我在我的案卷中添加了：

# Install Memcached for php 7
RUN set -eux 
&& pecl install memcached 
&& docker-php-ext-enable memcached 
&& true
