For IBM COS service authentication the following operator parameter should be used:
  • credentials

The parameter accepts the IBM Cloud Object Storage Credentials JSON from the IBM Cloud Object Storage service. The operator reads the required IAM credentials from the JSON.

Create IBM Cloud Object Storage Credentials

A service credential provides the necessary information to connect an application to Object Storage packaged in a JSON document. Service credentials are always associated with a Service ID, and new Service IDs can be created along with a new credential.

Use the following steps to create a service credential:

  1. Log in to the IBM Cloud console and navigate to your instance of Object Storage.
  2. In the side navigation, click Service Credentials.
  3. Click New credential and provide the necessary information.
  4. Click Add to generate service credential.
  5. Click View credentials and copy JSON into clipboard (use this as value of the credentials operator parameter).

This is an example of a service credential:
