S3 is an object storage API which is nearly ubiquitous, and can help in situations where data must accessed by multiple actors, such as in distributed training. - -This document guides you through the required setup, and provides examples on usage. - -## Configuration - -When reading or writing data on S3 with your TensorFlow program, the behavior -can be controlled by various environmental variables: - -* **AWS_REGION**: By default, regional endpoint is used for S3, with region - controlled by `AWS_REGION`. If `AWS_REGION` is not specified, then - `us-east-1` is used. -* **S3_ENDPOINT**: The endpoint could be overridden explicitly with - `S3_ENDPOINT` specified. -* **S3_USE_HTTPS**: HTTPS is used to access S3 by default, unless - `S3_USE_HTTPS=0`. -* **S3_VERIFY_SSL**: If HTTPS is used, SSL verification could be disabled - with `S3_VERIFY_SSL=0`. - -To read or write objects in a bucket that is not publicly accessible, -AWS credentials must be provided through one of the following methods: - -* Set credentials in the AWS credentials profile file on the local system, - located at: `~/.aws/credentials` on Linux, macOS, or Unix, or - `C:\Users\USERNAME\.aws\credentials` on Windows. -* Set the `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` environment - variables. -* If TensorFlow is deployed on an EC2 instance, specify an IAM role and then - give the EC2 instance access to that role. - -## Example Setup - -Using the above information, we can configure Tensorflow to communicate to an S3 endpoint by setting the following environment variables: - -```bash -AWS_ACCESS_KEY_ID=XXXXX # Credentials only needed if connecting to a private endpoint -AWS_SECRET_ACCESS_KEY=XXXXX -AWS_REGION=us-east-1 # Region for the S3 bucket, this is not always needed. Default is us-east-1. -S3_ENDPOINT=s3.us-east-1.amazonaws.com # The S3 API Endpoint to connect to. This is specified in a HOST:PORT format. -S3_USE_HTTPS=1 # Whether or not to use HTTPS. Disable with 0. -S3_VERIFY_SSL=1 # If HTTPS is used, controls if SSL should be enabled. Disable with 0. -``` - -## Usage - -Once setup is completed, Tensorflow can interact with S3 in a variety of ways. Anywhere there is a Tensorflow IO function, an S3 URL can be used. - -### Smoke Test - -To test your setup, stat a file: - -```python -from tensorflow.python.lib.io import file_io -print file_io.stat('s3://bucketname/path/') -``` - -You should see output similar to this: - -```console -<tensorflow.python.pywrap_tensorflow_internal.FileStatistics; proxy of <Swig Object of type 'tensorflow::FileStatistics *' at 0x10c2171b0> > -``` - -### Reading Data - -When [reading data](../api_guides/python/reading_data.md), change the file paths you use to read and write -data to an S3 path. For example: - -```python -filenames = ["s3://bucketname/path/to/file1.tfrecord", - "s3://bucketname/path/to/file2.tfrecord"] -dataset = tf.data.TFRecordDataset(filenames) -``` - -### Tensorflow Tools - -Many Tensorflow tools, such as Tensorboard or model serving, can also take S3 URLS as arguments: - -```bash -tensorboard --logdir s3://bucketname/path/to/model/ -tensorflow_model_server --port=9000 --model_name=model --model_base_path=s3://bucketname/path/to/model/export/ -``` - -This enables an end to end workflow using S3 for all data needs. - -## S3 Endpoint Implementations - -S3 was invented by Amazon, but the S3 API has spread in popularity and has several implementations. The following implementations have passed basic compatibility tests: - -* [Amazon S3](https://aws.amazon.com/s3/) -* [Google Storage](https://cloud.google.com/storage/docs/interoperability) -* [Minio](https://www.minio.io/kubernetes.html) |
