Configure remote storage
The Remote Storage module provides the option to store media files and schedule imports/exports in a persistent, remote storage container using a storage service, such as AWS S3. By default, Magento stores media files in the same filesystem that contains the application. This is inefficient for complex, multi-server configurations, and can result in degraded performance when sharing resources. With the Remote Storage module, you can store media files in the pub/media directory and import/export files in the var directory of the remote object storage to take advantage of server-side image resizing.
Remote storage is available in version 2.4.2 and later only. See the 2.4.2 release notes.
Remote storage options
You can configure remote storage using the remote-storage option with the setup CLI command. The remote-storage option uses the following syntax:
1
--remote-storage-<parameter-name>="<parameter-value>"
The parameter-name refers to the specific remote storage parameter name. The following table lists the parameters available for configuring remote storage:
| Command line Parameter | Parameter name | Description | Default value |
|---|---|---|---|
remote-storage-driver |
driver | Adapter name Possible values: file: Disables remote storage and uses the local filesystem aws-s3: Use the Amazon Simple Storage Service (Amazon S3) |
none |
remote-storage-bucket |
bucket | Object storage or container name | none |
remote-storage-prefix |
prefix | Optional prefix (location inside of object storage) | empty |
remote-storage-region |
region | Region name | none |
remote-storage-key |
access key | Optional access key | empty |
remote-storage-secret |
secret key | Optional secret key | empty |
Storage adapters
The default storage location is in the local filesystem. A storage adapter enables you to connect to a storage service and store your files anywhere. Magento supports configuring the following storage services:
Enable remote storage
You can install remote storage during a new Magento installation or add it to an existing Magento instance using remote-storage parameter name-and-value pairs with setup CLI commands. Minimally, you must supply the storage driver, bucket, and region.
The following examples enable the remote storage with an AWS S3 storage adapter in the US:
-
Install new Magento with remote storage
1
bin/magento setup:install --remote-storage-driver="aws-s3" --remote-storage-bucket="myBucket" --remote-storage-region="us-east-1"
-
Enable remote storage on existing Magento
1
bin/magento setup:config:set --remote-storage-driver="aws-s3" --remote-storage-bucket="myBucket" --remote-storage-region="us-east-1"
Limitations
Enabling remote storage might affect your established development experience. For example, certain PHP file functions might not work as expected. The usage of Magento Framework for file operations must be enforced.
The list of prohibited PHP native functions is available in Magento Coding Standard repository.
Migrate content
After you enable remote storage for a specific adapter, you can use the CLI to migrate existing media files to the remote storage.
1
./magento2ce/bin/magento remote-storage:sync
The sync command only migrates files in the pub/media directory, not the import/export files in the var directory. See Scheduled Import/Export in the Magento 2.4 User Guide.
