Hi!

Cost Comparison uses service credentials that you specified in the file https://github.com/hystax/optscale/blob/integration/optscale-deploy/overlay/user_template.yml when deploying OptScale (service_credentials section).

These credentials are necessary to receive pricing information from clouds.

Your problems:

1. AWS - most likely the user listed in service_credentials section does not have enough permissions to get priсing. As a start point you can use the following default policies combination - AmazonEC2ReadOnlyAccess and AWSPriceListServiceFullAccess. The policies can be added as follows:
   • Open AWS Cloud Console
   • Select IAM section
   • Select user whose keys you specified in fields access_key_id and secret_access_key

     # service credentials for getting pricing information from the different clouds
     # recommendations will not work without this
     service_credentials:
       aws:
         access_key_id: accesskeyid
         secret_access_key: secretaccesskey

     • Add AmazonEC2ReadOnlyAccess and AWSPriceListServiceFullAccess policies for selected user
     • If you changed policies, then restart insider-api pod.
2. Azure - service credentials for Azure contain an error in tenant field. You can see how to identify tenant into documentation > Data Source Connection > Connecting an Azure account to OptScale.

To change service credentials:

1. Change service scredentials into your own user_template.yml file
2. Execute command

   ./runkube.py --with-elk  -o overlay/<new user_template.yml file> -- <deployment name> <your OptScale version>

   Alternatively you may change service credentials in etcd directly using:

   kubectl exec -it etcd-0 —etcd-walker
