Set up Openflow - Snowflake Deployment: Create Runtime role¶

Openflow - Snowflake Deployment requires the creation of a number of resources which are specific not to a deployment but to a specific runtime. Typically such resources include:

  • Creation of Runtime specific Runtime role

  • Creation of Runtime specific network rules and External Access Integrations (EAI)

This topic describes the creation of these resources.

  1. Create a Runtime Role and associated privileges to write data to Snowflake Runtime Role for Runtimes on Snowflake Deployment Section

  2. Associate Runtime Role. See Runtime Role for Runtimes in the Snowflake Deployment Section.

  3. Create External Access Integrations and associate them to Runtimes. See Creating External Access Integrations

  4. When Outbound PrivateLink connectivity is required to connect to a private system using SPCS Egress.

Create a runtime role¶

When creating and editing Openflow Runtimes, Runtime Owners will have the ability to associate a role with the Runtime. This role will be used for flows that execute within the Runtime. For more information about Runtime Roles, see What is a runtime role?.

Note

As OPENFLOW_ADMIN, you’ll create the Runtime role and grant it to OPENFLOW_ADMIN, so that users granted that role are authorized to set this role on the Runtime.

Creating a runtime role is a prerequisite for creating a Runtime and involves the following steps:

  1. Create the role itself

  2. Grant the role access to the warehouse used by the Runtime.

  3. Grant the role access to the Snowflake objects used by the Runtime.

  4. Grant the role access to the External Access Integrations used by the Runtime.

To create a runtime role:

  1. Create the required runtime role.

    Note

    <RUNTIMENAME> denotes the name of the associated runtime.

    USE ROLE OPENFLOW_ADMIN;

CREATE ROLE IF NOT EXISTS OPENFLOW_RUNTIME_ROLE_<RUNTIMENAME>;

GRANT ROLE OPENFLOW_RUNTIME_ROLE_<RUNTIMENAME> TO ROLE OPENFLOW_ADMIN;
    Copy

  2. Allow the runtime role to use an existing warehouse that you are planning to use for data ingestion. Use this warehouse later when configuring your connectors for runtimes where you will be using this runtime role.

    GRANT USAGE, OPERATE ON WAREHOUSE <OPENFLOW_INGEST_WAREHOUSE> TO ROLE OPENFLOW_RUNTIME_ROLE_<RUNTIMENAME>;
    Copy

  3. Allow the runtime role to use, create or otherwise access Snowflake objects.

    Note

    Depending on the Openflow connector being created the required underlying objects will vary. The example below is for illustration purposes only.

    GRANT USAGE ON DATABASE <OPENFLOW_SPCS_DATABASE> TO ROLE OPENFLOW_RUNTIME_ROLE_<RUNTIMENAME>;
GRANT USAGE ON SCHEMA <OPENFLOW_SPCS_SCHEMA> TO ROLE OPENFLOW_RUNTIME_ROLE_<RUNTIMENAME>;
    Copy

Creating Network Rules and External Access Integrations¶

Snowflake’s security model provides secure access to specific endpoints and systems external to Snowflake using network policies.

Two key aspects of network policies are Network rules and External Access Integrations (EAI). Each of which is used to provide secure access to external resources required by the runtime.

There are three steps that are required to create network rules and external access integrations:

  1. Create the network rule, grouping the network identifiers into logical areas.

  2. Create the external access integration (EAI), specifying the list of network rules and assuring the Runtime Role has USAGE on the EAI.

  3. Associate the EAI with the Runtime in the Openflow UI when creating Runtimes.

To create the required network rule and EAI, perform the following steps:

Note

These examples use RUNTIME_NAME as a placeholder for the name of the Runtime being created.

  1. Create an appropriate network rule. See CREATE NETWORK RULE for more information.

    Note

    <OPENFLOW_DATABASE> denotes the name of the database that will contain the network rule. Snowflake suggests creating a specific database for network rules and external access integrations related to Openflow.

    USE DATABASE <OPENFLOW_DATABASE>;

CREATE OR REPLACE NETWORK RULE OPENFLOW_<RUNTIME_NAME>_NETWORK_RULE
    MODE = EGRESS
    TYPE = HOST_PORT
    VALUE_LIST = ('comma separated list of host:port pairs');
    Copy

  2. Create the associated external integration. See CREATE EXTERNAL ACCESS INTEGRATION for more information.

    USE ROLE ACCOUNTADMIN;

CREATE OR REPLACE EXTERNAL ACCESS INTEGRATION OPENFLOW_<RUNTIME>_EAI
   ALLOWED_NETWORK_RULES = (OPENFLOW_<RUNTIME_NAME>_NETWORK_RULE)
   ENABLED = TRUE;
    Copy

  3. Grant access to the EAI to the previously created runtime role.

    GRANT USAGE ON INTEGRATION OPENFLOW_<RUNTIME_NAME>_EAI TO ROLE OPENFLOW_RUNTIME_ROLE_<RUNTIME_NAME>;
    Copy
