Storage - read/write utility for Google Cloud Platform Storage buckets.

A Go utility to facilitate reading/writing files from/to Google Cloud Platform Storage.

What?

This utility uses Google Application Credentials or GCP service accounts to connect to a Google Cloud Platform project and read/write files from/to Storage buckets.

Why?

This was written to provide GCP storage bucket functionality within auth. It wraps the Google provided Storage Go client.

How?

The best place to start is with the tests. If running locally, then ensure that Google Application Credentials have been created. If running from a GCP virtual machine, then ensure that the relevant service account (compute, appengine etc.) has the following IAM scopes: 'Storage Object Viewer' and 'Storage Object Creator', or 'Storage Object Admin'. See GCP service accounts for further details.

Examples

See the tests for usage examples.

Dependencies and services

This utilises the following fine pieces of work:

• GCP's Datastore Go client and Storage Go client

Installation

Install with

$ go get -u github.com/lidstromberg/storage

Environment Variables

You will also need to export (linux/macOS) or create (Windows) some environment variables.

Change LB_DEBUGON to true/false if you want verbose logging on/off. The other variables don't need to be changed.
