[FeatureRequest]-Choice of using IAM and IBM Cloud Identity

[maverickash8889]

Hi All,

Submitting a feature request for upgrading repo to support IAM way of authenticating services. The current implementation used in samples uses UserName and Passwords(IBM Cloud Identity) mechanism for authentication. With Oct 2018 press release! IBM suggests moving all services from cloud foundry to resource groups which supports IAM. We need to update the samples and middleware to accommodate both ways of authentication.

@maverickash8889 hey, thanks for bring this up.

You can use an IAM API key authentication with environment variables, in your docker deploy.yaml file, configure the following environment variables with your API key information and token service provider URL.

• Watson Assistant:

      WATSON_CONVERSATION_APIKEY=YOUR_API_KEY
      WATSON_CONVERSATION_TOKEN_SERVICE_PROVIDER_URL=https://iam.bluemix.net/identity/token

• Speech to Text:

      WATSON_STT_APIKEY=YOUR_API_KEY
      WATSON_STT_TOKEN_SERVICE_PROVIDER_URL=https://iam.bluemix.net/identity/token

• Text to Speech:

      WATSON_TTS_APIKEY=YOUR_API_KEY
      WATSON_TTS_TOKEN_SERVICE_PROVIDER_URL=https://iam.bluemix.net/identity/token
