@Marvin in prefect self hosted how can i add snowflake block

To add a Snowflake block in a self-hosted Prefect instance, you should use the

prefect-snowflake

package. Here's an excerpt from the documentation that explains the process: 1. Install

prefect-snowflake

package using pip:

pip install prefect-snowflake

2. Save your Snowflake credentials as a credentials block:

python
   from prefect_snowflake import SnowflakeCredentials

   credentials = SnowflakeCredentials(
      account="ACCOUNT-PLACEHOLDER", # resembles nh12345.us-east-2.aws
      user="USER-PLACEHOLDER",
      password="PASSWORD-PLACEHOLDER"
   )
   credentials.save("CREDENTIALS-BLOCK-NAME-PLACEHOLDER")

3. Then, create and save a Snowflake connector block:

python
   from prefect_snowflake import SnowflakeConnector

   credentials = SnowflakeCredentials.load("CREDENTIALS-BLOCK-NAME-PLACEHOLDER")
   connector = SnowflakeConnector(
      credentials=credentials,
      database="DATABASE-PLACEHOLDER",
      schema="SCHEMA-PLACEHOLDER",
      warehouse="WAREHOUSE-PLACEHOLDER"
   )
   connector.save("CONNECTOR-BLOCK-NAME-PLACEHOLDER")

4. Register blocks in this module to view and edit them on Prefect Cloud (applicable for Prefect Cloud, modify if necessary for your self-hosted setup):

prefect block register -m prefect_snowflake

Please note that the placeholders in the code should be replaced with your actual Snowflake credentials, database, schema, and warehouse names. For more detailed information and setup instructions, you can visit the Prefect Snowflake documentation.

step 4 is not necessarily unless you need a new type of block

@Marvin in kubernetes deployment of self hosted prefect how can I install blocks via EXTRA_PIP_PACKAGES

To install blocks in a Kubernetes deployment of a self-hosted Prefect via

EXTRA_PIP_PACKAGES

, you can set environment variables when configuring your Kubernetes work pool. If you're using a Prefect-maintained image, and the image's entrypoint isn't overwritten, you can specify the Python packages to be installed at runtime. For example, you would add the following to your environment variables configuration:

json
{"EXTRA_PIP_PACKAGES": "prefect-snowflake==0.0.1"}

This will install the

prefect-snowflake

package when the flow run starts. Replace

prefect-snowflake==0.0.1

with the specific package and version you wish to install. For more information on setting up the Kubernetes deployment and work pool configuration, please refer to the Prefect Kubernetes Deployment Guide. If you need to include multiple packages, you can list them separated by spaces within the

EXTRA_PIP_PACKAGES

environment variable, much like you would in a

requirements.txt

file:

json
{"EXTRA_PIP_PACKAGES": "prefect-snowflake==0.0.1 another-package==2.0.0"}

Remember to replace the package names and versions with those that you actually need.
