APCu is not enabled ? Cant create fixtures

  docker, dockerfile, symfony, symfony-3.3

Hello I have a problem using the command :

php bin / console d: f: l


[Symfony  Component  Cache  Exception  CacheException]
  APCu is not activated

While Symfony 3 recognizes acpu extension very well …
For information, I am on docker and I have successfully installed the ACPu extension

Symfony detects the cache well but I don’t know why the script doesn’t want to start. I tried to take inspiration from other DockerFile but still the same problem …

My php DockerFile :

    FROM php:7.2-fpm-alpine
