[alvarosanchez]

Implement the ResourceLoader interface to get the objects using shorter URI in common format.

<object-storage-name>://path/to/file

• is the ObjectStorage#getName

Then for configuration:

micronaut:
  object-storage:
    aws:
      public-images:
        bucket: public-images-bucket

The locator would be: public-images://path/to/file

[s3|os|gs|azb]:([cloud-provider-specifics]:)*//<storage-name>/path/to/file

Where for the cloud providers:

• AWS
  • format: s3://<bucket-name>/path/to/file
  • example: s3://micronaut-object-storage/micronaut-buffer-netty-3.1.1.pom
• Azure
  • format: azb:<storage-account-name>://<container>/path/to/file
  • example: azb:micronautpgressatest://micronaut-object-storate/micronaut-buffer-netty-3.1.1.pom
• Google Cloud
  • format: gs://<bucket-name>/path/to/file
  • example: sgs//micronaut-object-storage/micronaut-buffer-netty-3.1.1.pom
• Oracle Cloud
  • format: os:<region>:<namespace>://<bucket-name>/path/to/file
  • example: os:us-ashburn-1:cloudnative-devrel://micronaut-object-storate/micronaut-buffer-netty-3.1.1.pom
