Secrets

When you don't know how to set secrets, please refer to Managing Workflow Secret

  • aws.redshift.password: NAME

    Optional user password to use when connecting to the Redshift database.

  • aws.redshift_load.access_key_id, aws.redshift.access_key_id, aws.access_key_id

    The AWS Access Key ID to use when accessing data source. This value is used to get temporary security credentials by default. See temp_credentials option for details.

  • aws.redshift_load.secret_access_key, aws.redshift.secret_access_key, aws.secret_access_key

    The AWS Secret Access Key to use when accessing data source. This value is used to get temporary security credentials by default. See temp_credentials option for details.

  • aws.redshift_load.role_arn, aws.redshift.role_arn, aws.role_arn

    Optional Amazon resource names (ARNs) used to copy data to the Redshift. The role needs AssumeRole role to use this option. Requires temp_credentials to be true. If this option isn't specified, this operator tries to use a federated user

Options

  • database: NAME

    Database name.

    Examples:

  database: my_db
  • host: NAME

    Hostname or IP address of the database.

    Examples:

  • temp_credentials: BOOLEAN

    Whether this operator uses temporary security credentials. Default: true. This operator tries to use temporary security credentials as follows:

    • If role_arn is specified, it calls AssumeRole action
    • If not, it calls GetFederationToken action

    See details about AssumeRole and GetFederationToken in the documents of AWS Security Token Service.

    So either of AssumeRole or GetFederationToken action is called to use temporary security credentials by default for secure operation. But if this option is disabled, this operator uses credentials as-is set in the secrets insread of temporary security credentials.

    Examples:

  temp_credentials: false
  • session_duration INTEGER

    Session duration of temporary security credentials. Default: 3 hour. This option isn't used when disabling temp_credentials

    Examples:

  session_duration: 1800
