Unable to use Apc cache within CakePHP shell

So I get this famous error while try to run shell script (through browser is working without issues)

Fatal error: Uncaught CacheException: Cache engine "default" is not properly configured.

default is pointing to Apc cache.

Cache::config('default', array(
    'engine' => 'Apc',
    'prefix' => 'some_default',
    'duration' => '+1 hour'
));

Stack trace:

#0 /.../lib/Cake/Cache/Cache.php(151): Cache::_buildEngine('default')
#1 /.../app/Config/core.php(381): Cache::config('default', Array)
#2 /.../lib/Cake/Core/Configure.php(72): include('/home/...')
#3 /.../lib/Cake/bootstrap.php(432): Configure::bootstrap(true)
#4 /.../lib/Cake/Console/ShellDispatcher.php(145): require('/home/...')
#5 /.../lib/Cake/Console/ShellDispatcher.php(100): ShellDispatcher->_bootstrap()
#6 /.../lib/Cake/Console/ShellDispatcher.php(54): ShellDispatcher->_initEnvironment()
#7 /home/ in /.../lib/Cake/Cache/Cache.php on line 186

Environment:

Apache/2.4.18 (Ubuntu)
PHP 7.0.13-0ubuntu0.16.04.1 (cli)
CakePHP v2.8.0

php -i | grep apc:

apc.coredump_unmap => Off => Off
apc.enable_cli => On => On
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

Cake tmp folder - permissions 777 owned by www-data user (which run apache also) tmp contains /cache, tmp/cache/models, tmp/cache/persistent and tmp/logs with the same permission as tmp.

If I change default engine from Apc to Redis for example, everything works without issues.

Apc for php7.0 is deprecated, so you need install apcu and than apcu-bc - for compatibility with apc.

Maybe is only in my case but when i put in .../cli/php.ini those lines

extension=apcu.so
extension=apc.so

apcu.enabled=1
apc.enable_cli=1

Apc still not work, i got warnings:

default cache was unable to write 'key' to Apc cache

It start to work when i create two files

.../cli/config.d/apcu.ini which contains:

extension=apcu.so

and .../cli/config.d/z_apc.ini which contains:

extension=apc.so
apc.enable_cli=1

(z prefix is for order, apc should be loaded after apcu)
