MAGE_DIRS bootstrap parameters in CLI

Question

In pub/index.php, the following code is used to set change URLs for media and static assets to omit "/pub":

$params[Bootstrap::INIT_PARAM_FILESYSTEM_DIR_PATHS] = [
    DirectoryList::PUB => [DirectoryList::URL_PATH => ''],
    DirectoryList::MEDIA => [DirectoryList::URL_PATH => 'media'],
    DirectoryList::STATIC_VIEW => [DirectoryList::URL_PATH => 'static'],
    DirectoryList::UPLOAD => [DirectoryList::URL_PATH => 'media/upload'],
];
$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $params);

Unfortunately in CLI scripts (bin/magento) there is nothing like this.

I found the class Magento\Setup\Mvc\Bootstrap\InitParamListener with the following code:

$initParams = $application->getServiceManager()->get(self::BOOTSTRAP_PARAM);
$directoryList = $this->createDirectoryList($initParams);

But I don't understand where this Zend Service Manager retrieves the data and how it might be possible to influence it.

My concrete problem is that an indexer has to generate full URLs and currently does it like http://magento.local/pub/media/..., where I need it to be http://magento.local/media/...

How can I tell the CLI that my virtual host points to pub and "pub" should not be part of URLs?

Ideally this should work without having to rely on additional CLI parameters or environment variables.

Answer 1

After much travail, I found a solution using environment variables, which I know isn't what you wanted. You can set the parameters using environment variables like this (replacing $APP_ROOT with your actual Magento root):

env \
    "MAGE_DIRS[base][path]=$APP_ROOT" \
    "MAGE_DIRS[pub][uri]=" \
    "MAGE_DIRS[media][uri]=media" \
    "MAGE_DIRS[static][uri]=static" \
    "MAGE_DIRS[upload][uri]=media/upload" \
    bin/magento indexer:reindex

Note that it's necessary to specify the base path as above because when you use environment variables, your MAGE_DIRS definition overwrites the initial default that includes that. It will, however, get merged with the fuller default config in \Magento\Framework\App\Filesystem\DirectoryList.

Credit to this answer from the chief architect himself for putting me on the scent:

Answer 2

Another, simpler option is to simply hard-code the media path in the store config under Stores > Configuration > Web to:

{{unsecure_base_url}}media/

and

{{secure_base_url}}media/

Answer 3

I found another way to set MAGE_DIRS via CLI, just copy

/vendor/magento/framework/App/Filesystem/DirectoryList.php

to

/lib/internal/Magento/Framework/App/Filesystem/DirectoryList.php 

And now you can change default directory of all internal files.
