Overview

LocalStack for Snowflake helps software and data teams save on Snowflake Cloud costs by running dev and staging workflows on locally deployable, Snowflake-compatible development and CI environments.

LocalStack for Snowflake supports the following features:

• Query operations on warehouses, databases, schemas, and tables
• Storage and persistence with user/data/named stages
• Client support for tools like SnowPark, DBeaver, and Flyway
• Streaming with Snowpipe support
• JavaScript and Python UDFs
• External volumes, including Iceberg tables
• … and more!

Installation

The easiest way to get started with LocalStack for Snowflake is to download and run the LocalStack for Snowflake Docker image, available on Docker Hub:

docker pull localstack/snowflake:latest

NOTE: LocalStack for Snowflake requires a valid LocalStack auth token, configured as environment variable LOCALSTACK_AUTH_TOKEN, to work. Refer to the LocalStack auth token guide for more details.

Start LocalStack for Snowflake - localstack

Assuming the localstack CLI is installed and configured correctly, you can start the LocalStack for Snowflake instance via the following command:

LOCALSTACK_AUTH_TOKEN=<your_auth_token> \
IMAGE_NAME=localstack/snowflake \
localstack start

Start LocalStack for Snowflake - docker

Assuming the docker CLI is installed and correctly configured, you can start the LocalStack for Snowflake instance via the following command:

docker run \
  --rm -it \
  -p 4566:4566 \
  -e LOCALSTACK_AUTH_TOKEN=${LOCALSTACK_AUTH_TOKEN:?} \
  localstack/snowflake

Start LocalStack for Snowflake - docker-compose

Create a docker-compose.yml file with the specified content:

version: "3.8"

services:
  localstack:
    container_name: "localstack-main"
    image: localstack/snowflake
    ports:
      - "127.0.0.1:4566:4566"
    environment:
      - LOCALSTACK_AUTH_TOKEN=${LOCALSTACK_AUTH_TOKEN:?}
    volumes:
      - "./volume:/var/lib/localstack"

Assuming the docker CLI command is installed and configured correctly, start the Snowflake Docker container with the following command:

docker compose up

Quickstart

After starting the LocalStack for Snowflake instance, you can use the Snowflake Python Connector to interact with the LocalStack Snowflake emulator. The following example demonstrates how to create a Snowflake table using the Snowflake Python Connector:

connection = snowflake.connector.connect(
    user="test",
    password="test",
    account="test",
    database="test",
    host="snowflake.localhost.localstack.cloud", # For instances that run on the same machine as the client
    port=4566 # Use port 4566 for non-SSL, 443 for SSL connections
)
connection.cursor().execute("CREATE TABLE table1(col1 INT)")
