APCu is not enabled ? Cant create fixtures - docker

Question

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:

You have to enable apc for cli.
If you launch php -i, you should have something like that:
apc.coredump_unmap => Off => Off
apc.enable_cli => Off => Off
apc.enabled => On => On
apc.entries_hint => 4096 => 4096
apc.gc_ttl => 3600 => 3600
apc.mmap_file_mask => no value => no value
apc.preload_path => no value => no value
apc.serializer => php => php
apc.shm_segments => 1 => 1
apc.shm_size => 32M => 32M
apc.slam_defense => On => On
apc.smart => 0 => 0
apc.ttl => 0 => 0
apc.use_request_time => On => On
apc.writable => /tmp => /tmp
You can see apc.enable_cli is set to Off.
So, add this line to your Dockerfile:
RUN echo "apc.enable_cli=1" >> /usr/local/etc/php/conf.d/docker-php-ext-apcu.ini
