Basic information about Flysystem:-
Flysystem is a filesystem abstraction which allows you to easily swap out a local file system for a remote one. Reducing technical debt and chance of vendor lock-in.
You can sync your local files with a remote file storage like Dropbox / AWS S3 , other ftp or elsewhere. you can see below for the adaptors available for flysystem.
Also files can be directly stored from drupal content add form to remote file storage without manually syncing local file storage with the remote one.
Requirements:
Composer.
composer manager (optional).
If you have a different method of managing Composer dependencies, use that.
How to install Flysystem in Drupal:-
These are the basic steps in following below-
1. Download and install Composer_manager module.
2. Enter into /scripts directory inside composer_manager module directory and run init.sh in terminal. This registers the module's Composer command for Drupal core.
3. Download Flysystem module and place in /modules directory of drupal 8 setup.
4. Enter in /core directory in terminal and run “composer drupal-rebuild” and then “composer update” commands. This will install the dependencies required for the modules.
5. Install Flysystem module from drupal backend
Available adapters are:
- local
- ftp (Requires the ftp extension)
- dropbox (https://www.drupal.org/project/flysystem_dropbox)
- rackspace (https://www.drupal.org/project/flysystem_rackspace)
- aws s3 (https://www.drupal.org/project/flysystem_s3)
- sftp (https://www.drupal.org/project/flysystem_sftp)
- zip (https://www.drupal.org/project/flysystem_zip)
How to Configure:-
Stream wrappers are configured in settings.php.
$schemes = [
'dropboxexample' => [
'driver' => 'dropbox',
'config' => [
'token' => '[dropbox-token]',
'client_id' => [dropbox-email-id],
// Optional.
'prefix' => '[/dropbox subdirectory]',
],
],
's3example' => [
'type' => 's3',
'driver' => 's3',
'config' => [
'key' => '[S3 access key]',
'secret' => '[S3 secret key]',
'region' => '[region like eu-west-1]',
'bucket' => '[bucket-name]',
// Optional.
'prefix' => '[S3 subdirectory]', // Directory prefix for all uploaded/viewed files.
'cname' => '[S3 url]', // A cname that resolves to your bucket. Used for URL generation.
],
],
'localexample' => [ // The name of the stream wrapper. localexample://
'driver' => 'local', // The plugin key.
'config' => [
'root' => '[path to the file storage]', // If 'root' is inside the public directory,
], // then files will be served directly. Can be
// relative or absolute.
// Optional settings that apply to all adapters.
'cache' => FALSE, // Cache filesystem metadata. Not necessary,
// since this is a local filesystem.
'replicate' => 'dropboxexample', // 'replicate' writes to both filesystems, but
// reads from this one. Functions as a backup.
'serve_js' => TRUE, // Serve Javascript or CSS via this stream wrapper.
'serve_css' => TRUE, // This is useful for adapters that function as
// CDNs like the S3 adapter.
]
];
$settings['flysystem'] = $schemes;
The above configuration will add storage options to Flysystem configuration.
How it works:
1) Sync local storage with remote
a) Go to /admin/config/media/file-system/flysystem.
b) Select the Sync From and Sync To from the dropdown and Sync.
2) Store file remote directly
a) Go to manage field link of content type .
b) edit the field setting and change the upload destination.
Installation and Configuring Flysystem s3 module
Installation :
1. Install Flysystem and composer_manager.
2. Download Flysystem S3 module and place in /modules.
3. Enter in /core directory in terminal
4. Run “composer drupal-rebuild” and “composer update” command in terminal
5. Install Flysystem S3 from drupal backend
Configuration :
Add the S3 scheme configuration in settings.php file.
$schemes = [
's3example' => [
'type' => 's3',
'driver' => 's3',
'config' => [
'key' => '[S3 access key]',
'secret' => '[S3 secret key]',
'region' => '[region like eu-west-1]',
'bucket' => '[bucket-name]',
// Optional.
'prefix' => '[S3 subdirectory]', // Directory prefix for all uploaded/viewed files.
'cname' => '[S3 url]', // A cname that resolves to your bucket. Used for URL generation.
],
],
];
$settings['flysystem'] = $schemes;
Flysystem Scheme and file access control
.
Flysystem storage schemes works like private files in drupal 8.
It hides the actual link of the to file and delivers it via drupal generated path.Thus it restricts access to the original files and let other modules provide access control to the file.
But while using image style it provide access control only if the file is stored as private because the image style is rendered using ImageStyleDownloadController::deliver method and this method let other module to provide access control to the file if the file is stored as private file only.
// If using the private scheme, let other modules provide headers and
// control access to the file.
if ($scheme == 'private') {
if (file_exists($derivative_uri)) {
return parent::download($request, $scheme);
}
else {
$headers = $this->moduleHandler()->invokeAll('file_download', array($image_uri));
if (in_array(-1, $headers) || empty($headers)) {
throw new AccessDeniedHttpException();
}
}
}

aguchoca CreditAttribution: aguchoca commentedWhen you edit the field setting and change the upload destination it does not offer the flysystem options it supposed to offer using the settings in settings.php like S3, Dropbox, etc. right quick.
You have to run update script pr probably clear caches before getting an updated New files system.

chavab_1 CreditAttribution: chavab_1 commentedWhen I run
composer drupal-rebuild
from the core directory I getBut when I run it from the website root it works correctly. Am I doing something wrong or was there a revision made to the location of the files??

These are the steps you have to follow as the steps mentioned above are not complete.
Step - 2 Enter into /scripts directory inside composer_manager module directory and run init.sh in terminal. This registers the module's Composer command for Drupal core.
when you follow this step you will not see init.sh,you will see init.php and you can simply run php init.php
after that composer.json that is in your root directory of your project will add two commands drupal-rebuild and drupal update.
Step - 3. Download Flysystem module and place in /modules directory of drupal 8 setup.
Step - 4 Enter in /core directory in terminal and run “composer drupal-rebuild” and then “composer update” commands. This will install the dependencies required for the modules.
you does'not have to enter in core directory. simply run that command in project folder, it will work
Comment #5
hansfn CreditAttribution: hansfn as a volunteer commentedWhat is this node really? Is it an effort to provide documentation for the Flysystem module? The module already has proper documentation in the readme (which is linked to from the project/module page). Or is it a real issue with the module? Anyway, I'm moving the issue to the module issue queue so the maintainer can decide if the node contains anything useful.
Comment #6
twistor CreditAttribution: twistor as a volunteer commented@hansfn, thanks for that. Personally, I would rather keep the README up to date than a bunch of pages on D.O.
That said, I'm fine with creating some docs pages for people to explain how things work.
If anyone wants to summarize the useful bits from this issue, that'd be great. Otherwise, it will wait till a stable release.

DamienMcKennaComment #8
DamienMcKennaPer @twistor's suggestion, lets improve the included documentation.
I've updated the README.md file to correct the syntax of the example settings, and add a new "Usage" section.
Comment #9
DamienMcKennaNote: S3 support should be documented in the S3 submodule, not the main module.

shakilahmadHi, there is no composer_manager module for Drupal 8 and also not included in core. So, I am confused about the step
"Step - 2 Enter into /scripts directory inside composer_manager module directory and run init.sh in terminal. This registers the module's Composer command for Drupal core."
