fog credentials checker

This project includes an executable dingo-postgresql-fog-check that checks one or more fog configuration files for valid access to an object storage bucket.

Currently it supports testing Amazon S3 storage credentials (the object storage supported by Dingo PostgreSQL).

Simple testing

Ok, so this draft of the tool was written quickly and manually tested against some sample input files.

You can recreate sample input files with your own credentials and your own Amazon S3 account.

Create tmp/creds.yml:

default:
  aws_access_key_id: XXX
  aws_secret_access_key: YYY
  bucket_name: bucket-in-us-east-1

Then merge it with the fixture files:

./fixtures/make_fog_files.sh tmp/creds.yml

The tmp directory will be filled with sample files. Those ending with -good.yml should complete successfully. All other should error.

Then run each one:

bundle exec bin/dingo-postgresql-fog-check tmp/fog-region-good.yml

To run an example that should fail:

bundle exec bin/dingo-postgresql-fog-check tmp/fog-bucket-unknown.yml

The output might look like:

{:aws_access_key_id=>"XXX", :aws_secret_access_key=>"REDACTED", :bucket_name=>"see-no-evil-hear-no-evil", :provider=>"AWS", :region=>"us-east-1"}
ERROR: bucket 'see-no-evil-hear-no-evil' not found
