For example: I have one class which have ClassA::create();

How to register this factory in ContainerBuilder?

$containerBuilder = new ContainerBuilder();

$containerBuilder
    ->register('access_manager', AccessManager::class)
    ->addArgument([new Reference('post_voter')]);

You call setFactory().

E.g.:

$containerBuilder = new ContainerBuilder();

$containerBuilder
    ->register('access_manager', AccessManager::class)
    ->addArgument([new Reference('post_voter')]);

$containerBuilder->register(ClassA::class)
                  ->setClass(ClassA::class)
                  ->setFactory([ClassA::class, 'create']);

If you want the factory to create new instances of the service each time it's accessed, you'd need to add a call to setShared(false).

Here you can see an example on an online sandbox: https://phpsandbox.io/e/x/qhhxv
