Terraform Provider: Snowflake

This is a terraform provider plugin for managing Snowflake accounts. Initially developed by Chan Zuckerberg, currently maintained by Viostream.

Install

go get -u github.com/viostream/terraform-provider-snowflake
# *NIX
mv $GOPATH/bin/terraform-provider-snowflake ~/.terraform.d/plugins

Authentication

<<<<<<< HEAD <<<<<<< HEAD We currently only support username + password auth and suggest that you only do so via environment variables. So a config something like:

We currently support username + password and keypair auth and suggest that you do so via environment variables. Define a config with something like-

7dd55fa02ff8b69235d11375c3fb5f2028e5146b ======= We currently support username + password, browser and keypair authenthication. We suggest that you do so via environment variables. Define a config with the non-senstive field like- 4346dee4430764fa7c608a761b5ffd3c53650631

provider "snowflake" {
  account = "..."
  role    = "..."
  region  = "..."
}

Then set SNOWFLAKE_USER and either SNOWFLAKE_PASSWORD or SNOWFLAKE_PRIVATE_KEY_PATH.

Keypair Authentication Environment Variables

You should generate the public and private keys and set up environment variables.

cd ~/.ssh
openssl genrsa -out snowflake_key 4096
openssl rsa -in snowflake_key -pubout -out snowflake_key.pub

To export the variables into your provider:

export SNOWFLAKE_USER="..."
export SNOWFLAKE_PRIVATE_KEY_PATH="~/.ssh/snowflake_key"

Username and Password Environment Variables

If you choose to use Username and Password Authentication, export these credentials:

export SNOWFLAKE_USER='...'
export SNOWFLAKE_PASSWORD='...'

We support managing a subset of snowflakedb resources, with a focus on access control and management. We've built and support the resources we use. If you are lookig for others to be supported we are more than happy to get PRs merged.

You can see a number of examples here.

snowflake_account_grant

Note: The snowflake_account_grant resource creates exclusive attachments of grants. Across the entire Snowflake account, all of the accounts to which a single grant is attached must be declared by a single snowflake_account_grant resource. This means that even any snowflake_account that have the attached grant via any other mechanism (including other Terraform resources) will have that attached grant revoked by this resource. These resources do not enforce exclusive attachment of a grant, it is the user's responsibility to enforce this.

Development

To do development you need Go installed, this repo cloned and that's about it. It has not been tested on Windows, so if you find problems let us know.

<<<<<<< HEAD If you want to build and test the provider localling there is a make target `make install-tf` that will build the provider binary and install it in a location that terraform can find.

Testing

For the Terraform resources, there are 3 levels of testing - internal, unit and acceptance tests.

The 'internal' tests are run in the github.com/viostream/terraform-provider-snowflake/pkg/resources package so that they can test functions that are not exported. These tests are intended to be limited to unit tests for simple functions.

The 'unit' tests are run in github.com/viostream/terraform-provider-snowflake/pkg/resources_test, so they only have access to the exported methods of resources. These tests exercise the CRUD methods that on the terraform resources. Note that all tests here make use of database mocking and are run locally. This means the tests are fast, but are liable to be wrong in suble ways (since the mocks are unlikely to be perfect).

You can run these first two sets of tests with make test.

The 'acceptance' tests run the full stack, creating, modifying and destroying resources in a live snowflake account. To run them you need a snowflake account and the proper environment variables set: SNOWFLAKE_ACCOUNT, SNOWFLAKE_USER, SNOWFLAKE_PASSWORD, SNOWFLAKE_ROLE. These tests are slower but have higher fidelity.

To run all tests, including the acceptance tests, run make test-acceptance.

<<<<<<< HEAD Note that we also run all tests in our Travis-CI account.

We also run all tests in our Travis-CI account.

Pull Request CI

Our CI jobs run the full acceptence test suite, which involves creating and destroying resources in a live snowflake account. Travis-CI is configured with environment variables to authenticate to our test snowflake account. For security reasons, those variables are not available to forks of this repo.

If you are making a PR from a forked repo, you can create a new Snowflake trial account and set up Travis to build it by setting these environement variables:

SNOWFLAKE_ACCOUNT - The account name
SNOWFLAKE_USER - A snowflake user for running tests.
SNOWFLAKE_PASSWORD - Password for that user.
SNOWFLAKE_ROLE - Needs to be ACCOUNTADMIN or similar.
SNOWFLAKE_REGION - Default is us-west-2, set this if your snowflake account is in a different region.

If you are using the Standard Snowflake plan, it's recommended you also set up the following environment variables to skip tests for features not enabled for it:

SKIP_DATABASE_TESTS - to skip tests with retention time larger than 1 day
SKIP_WAREHOUSE_TESTS - to skip tests with multi warehouses
