Synapse S3 Storage Provider
This module can be used by synapse as a storage provider, allowing it to fetch and store media in Amazon S3.
s3_storage_provider.py should be on the PYTHONPATH when starting
Example of entry in synapse config:
media_storage_providers: - module: s3_storage_provider.S3StorageProviderBackend store_local: True store_remote: True store_synchronous: True config: bucket: <S3_BUCKET_NAME> # All of the below options are optional, for use with non-AWS S3-like # services, or to specify access tokens here instead of some external method. region_name: <S3_REGION_NAME> endpoint_url: <S3_LIKE_SERVICE_ENDPOINT_URL> access_key_id: <S3_ACCESS_KEY_ID> secret_access_key: <S3_SECRET_ACCESS_KEY> # The object storage class used when uploading files to the bucket. # Default is STANDARD. #storage_class: "STANDARD_IA" # The maximum number of concurrent threads which will be used to connect # to S3. Each thread manages a single connection. Default is 40. # #threadpool_size: 20
This module uses
boto3, and so the credentials should be specified as
Regular cleanup job
There is additionally a script at
scripts/s3_media_upload which can be used
in a regular job to upload content to s3, then delete that from local disk.
This script can be used in combination with configuration for the storage
provider to pull media from s3, but upload it asynchronously.
Once the package is installed, the script should be run somewhat like the
following. We suggest using
screen as these can take a long time
on larger servers.
database.yaml should contain the keys that would be passed to psycopg2 to
connect to your database. They can be found in the contents of the
args parameter in your homeserver.yaml.
More options are available in the command help.
