Running tusd

Starting the tusd upload server is as simple as invoking a single command. For example, following snippet demonstrates how to start a tusd process which accepts tus uploads at http://localhost:1080/files/ (notice the trailing slash) and stores them locally in the ./data directory:

$ tusd -upload-dir=./data
[tusd] 2019/09/29 21:10:50 Using './data' as directory storage.
[tusd] 2019/09/29 21:10:50 Using 0.00MB as maximum size.
[tusd] 2019/09/29 21:10:50 Using 0.0.0.0:1080 as address to listen.
[tusd] 2019/09/29 21:10:50 Using /files/ as the base path.
[tusd] 2019/09/29 21:10:50 Using /metrics as the metrics path.
[tusd] 2019/09/29 21:10:50 Supported tus extensions: creation,creation-with-upload,termination,concatenation,creation-defer-length
[tusd] 2019/09/29 21:10:50 You can now upload files to: http://0.0.0.0:1080/files/

Alternatively, if you want to store the uploads on an AWS S3 bucket, you only have to specify the bucket and provide the corresponding access credentials and region information using environment variables (if you want to use a S3-compatible store, use can use the -s3-endpoint option):

$ export AWS_ACCESS_KEY_ID=xxxxx
$ export AWS_SECRET_ACCESS_KEY=xxxxx
$ export AWS_REGION=eu-west-1
$ tusd -s3-bucket=my-test-bucket.com
[tusd] 2019/09/29 21:11:23 Using 's3://my-test-bucket.com' as S3 bucket for storage.
[tusd] 2019/09/29 21:11:23 Using 0.00MB as maximum size.
[tusd] 2019/09/29 21:11:23 Using 0.0.0.0:1080 as address to listen.
[tusd] 2019/09/29 21:11:23 Using /files/ as the base path.
[tusd] 2019/09/29 21:11:23 Using /metrics as the metrics path.
[tusd] 2019/09/29 21:11:23 Supported tus extensions: creation,creation-with-upload,termination,concatenation,creation-defer-length
[tusd] 2019/09/29 21:11:23 You can now upload files to: http://0.0.0.0:1080/files/

If your S3 bucket has been configured for AWS S3 Transfer Acceleration and you want to make use of that advanced service, you can direct tusd to automatically use the designated AWS acceleration endpoint for your bucket by including the optional command line flag s3-transfer-acceleration as follows:

$ export AWS_ACCESS_KEY_ID=xxxxx
$ export AWS_SECRET_ACCESS_KEY=xxxxx
$ export AWS_REGION=eu-west-1
$ tusd -s3-bucket=my-test-bucket.com -s3-transfer-acceleration
[tusd] 2019/09/29 21:11:23 Using 's3://my-test-bucket.com' as S3 bucket for storage with AWS S3 Transfer Acceleration enabled.
[tusd] 2019/09/29 21:11:23 Using 0.00MB as maximum size.
[tusd] 2019/09/29 21:11:23 Using 0.0.0.0:1080 as address to listen.
[tusd] 2019/09/29 21:11:23 Using /files/ as the base path.
[tusd] 2019/09/29 21:11:23 Using /metrics as the metrics path.
[tusd] 2019/09/29 21:11:23 Supported tus extensions: creation,creation-with-upload,termination,concatenation,creation-defer-length
[tusd] 2019/09/29 21:11:23 You can now upload files to: http://0.0.0.0:1080/files/

tusd is also able to read the credentials automatically from a shared credentials file (~/.aws/credentials) as described in https://github.com/aws/aws-sdk-go#configuring-credentials. But be mindful of the need to declare the AWS_REGION value which isn't conventionally associated with credentials.

Furthermore, tusd also has support for storing uploads on Google Cloud Storage. In order to enable this feature, supply the path to your account file containing the necessary credentials:

$ export GCS_SERVICE_ACCOUNT_FILE=./account.json
$ tusd -gcs-bucket=my-test-bucket.com
[tusd] Using 'gcs://my-test-bucket.com' as GCS bucket for storage.
[tusd] Using 0.00MB as maximum size.
[tusd] Using 0.0.0.0:1080 as address to listen.
[tusd] Using /files/ as the base path.
[tusd] Using /metrics as the metrics path.

Besides these simple examples, tusd can be easily configured using a variety of command line options:

$ tusd -help
Usage of tusd:
  -base-path string
    	Basepath of the HTTP server (default "/files/")
  -behind-proxy
    	Respect X-Forwarded-* and similar headers which may be set by proxies
  -expose-metrics
    	Expose metrics about tusd usage (default true)
  -gcs-bucket string
    	Use Google Cloud Storage with this bucket as storage backend (requires the GCS_SERVICE_ACCOUNT_FILE environment variable to be set)

  -hooks-dir string
    	Directory to search for available hooks scripts
  -hooks-enabled-events string

  -hooks-grpc-backoff int

  -max-size int
    	Maximum size of a single upload in bytes
  -metrics-path string
