Snowflake

Prepare credentials for Snowflake access Create RSA key pair for Snowflake user, you can use the following command to generate it:

openssl genrsa 2048 | openssl pkcs8 -topk8 -inform PEM -out rsa_key.p8 -nocrypt
openssl rsa -in rsa_key.p8 -pubout -out rsa_key.pub

Then you can use the public key in the Snowflake user creation script below.

CREATE ROLE "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE";
CREATE DATABASE "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE";

GRANT ALL PRIVILEGES ON DATABASE "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE" TO ROLE "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE";
GRANT USAGE ON WAREHOUSE "DEV" TO ROLE "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE";

CREATE USER "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE"
PASSWORD = ''
DEFAULT_ROLE = "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE"
RSA_PUBLIC_KEY = '<your_public_key>'
;

GRANT ROLE "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE" TO USER "KEBOOLA_CI_PHP_STORAGE_DRIVER_SNOWFLAKE";

set up env variables:
