If you'd like to store Synapse's content repository (media_store
) files on Amazon S3 (or other S3-compatible service), you can let this playbook configure Goofys for you.
Another (and better performing) way to use S3 storage with Synapse is synapse-s3-storage-provider.
Using a Goofys-backed media store works, but performance may not be ideal. If possible, try to use a region which is close to your Matrix server.
If you'd like to move your locally-stored media store data to Amazon S3 (or another S3-compatible object store), we also provide some migration instructions below.
After creating the S3 bucket and configuring it, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml
file (adapt to your needs):
matrix_s3_media_store_enabled: true
matrix_s3_media_store_bucket_name: "your-bucket-name"
matrix_s3_media_store_aws_access_key: "access-key-goes-here"
matrix_s3_media_store_aws_secret_key: "secret-key-goes-here"
matrix_s3_media_store_region: "eu-central-1"
You can use any S3-compatible object store by additionally configuring these variables:
matrix_s3_media_store_custom_endpoint_enabled: true
matrix_s3_media_store_custom_endpoint: "https://your-custom-endpoint"
If you have local media store files and wish to migrate to Backblaze B2 subsequently, follow our migration guide to Backblaze B2 below instead of applying this configuration as-is.
It's a good idea to make a complete server backup before migrating your local media store to an S3-backed one.
After making the backup, follow one of the guides below for a migration path from a locally-stored media store to one stored on S3-compatible storage:
-
Proceed with the steps below without stopping Matrix services
-
Start by adding the base S3 configuration in your
vars.yml
file (seen above, may be different depending on the S3 provider of your choice) -
In addition to the base configuration you see above, add this to your
vars.yml
file:matrix_s3_media_store_path: /matrix/s3-media-store
This enables S3 support, but mounts the S3 storage bucket to
/matrix/s3-media-store
without hooking it to your homeserver yet. Your homeserver will still continue using your local filesystem for its media store. -
Run the playbook to apply the changes:
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
-
Do an initial sync of your files by running this on the server (it may take a very long time):
sudo -u matrix -- rsync --size-only --ignore-existing -avr /matrix/synapse/storage/media-store/. /matrix/s3-media-store/.
You may need to install
rsync
manually. -
Stop all Matrix services (
ansible-playbook -i inventory/hosts setup.yml --tags=stop
) -
Start the S3 service by running this on the server:
systemctl start matrix-goofys
-
Sync the files again by re-running the
rsync
command you see in step #5 -
Stop the S3 service by running this on the server:
systemctl stop matrix-goofys
-
Get the old media store out of the way by running this command on the server:
mv /matrix/synapse/storage/media-store /matrix/synapse/storage/media-store-local-backup
-
Remove the
matrix_s3_media_store_path
configuration from yourvars.yml
file (undoing step #3 above) -
Run the playbook:
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
-
You're done! Verify that loading existing (old) media files works and that you can upload new ones.
-
When confident that it all works, get rid of the local media store directory:
rm -rf /matrix/synapse/storage/media-store-local-backup
-
While all Matrix services are running, run the following command on the server:
(you need to adjust the 3
--env
line below with your own data)docker run -it --rm -w /work \ --env='B2_KEY_ID=YOUR_KEY_GOES_HERE' \ --env='B2_KEY_SECRET=YOUR_SECRET_GOES_HERE' \ --env='B2_BUCKET_NAME=YOUR_BUCKET_NAME_GOES_HERE' \ --mount type=bind,src=/matrix/synapse/storage/media-store,dst=/work,ro \ --entrypoint=/bin/sh \ docker.io/tianon/backblaze-b2:3.6.0 \ -c 'b2 authorize-account $B2_KEY_ID $B2_KEY_SECRET && b2 sync /work b2://$B2_BUCKET_NAME --skipNewer'
This is some initial file sync, which may take a very long time.
-
Stop all Matrix services (
ansible-playbook -i inventory/hosts setup.yml --tags=stop
) -
Run the command from step #1 again.
Doing this will sync any new files that may have been created locally in the meantime.
Now that Matrix services aren't running, we're sure to get Backblaze B2 and your local media store fully in sync.
-
Get the old media store out of the way by running this command on the server:
mv /matrix/synapse/storage/media-store /matrix/synapse/storage/media-store-local-backup
-
Put the Backblaze B2 settings in your
vars.yml
file -
Run the playbook:
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
-
You're done! Verify that loading existing (old) media files works and that you can upload new ones.
-
When confident that it all works, get rid of the local media store directory:
rm -rf /matrix/synapse/storage/media-store-local-backup
