SSM Key

The security credentials will be stored in the following security credentials in the digital Jenkins. These credentials are used to populate the SSM key below in the respective environments. This secure attribute is created from the common-infrastructure repository.

SSM Parameter Name
storepick_datadog_apikey

Value:

{
    "DD_KMS_API_KEY": "....",
    "DD_KMS_APPLICATION_KEY": "...."
}

Configuration

Config service is being used by the Bigquery Update Lambda to fetch the Dataset and Table Names. New Config is not required in this case, we can modify existing config used by respective repos to add atrributes related to BigQuery.

Each repo will use config which has been setup for it e.g. NHS Discount repo will use storepick-nhs-discount.json

Config used by NHSDiscount repo
storepick-nhs-discount.json

Value:

{
    ...
    "BIG_QUERY_DATASET": "store_pick_discount",
    "BIG_QUERY_TABLE": "nhs_discount",
    ...
}
