dbt-init

A tool to create dbt projects for consulting. dbt-init will create a project as a subdirectory within the target directory you provide it, and populate as much of the dbt project as possible

Installation & usage

  1. Install using pip install dbt-init
  2. To create a new client project run a command like following:
$ dbt-init --client jaffle-shop --warehouse snowflake --target-dir ~/clients/

You can also check the available arguments with dbt-init --help

Once you've created your project

  1. Update sample.profile.yml to contain the correct profile details for your client, excluding the actual credentials – e.g. username and password:
  • You can often pre-fill the host and database name.
  • You may want to use an alternate connection method (e.g. OAuth) and update the sample file to reflect this.
  1. Ensure that the users/groups/roles within a warehouse match the grant statements in the post-run hooks (defined in dbt_project.yml).

Building out the starter project

If you're interested in helping build out the starter project, here is a list of variables you can use – a lot of them have defaults based on the client name.

{{ project.name }}: The name of the project, as defined in `dbt_project.yml`, e.g. jaffle_shop.
{{ project.warehouse }}: The warehouse that a client is using.
{{ project.client_name }}: The name of the client, e.g. jaffle-shop.
{{ project.dir_name }}: The name of the directory this project is in, e.g. jaffle-shop-dbt.
{{ project.profile_name }}: The name of the profile used by this project, e.g. jaffle_shop.

Testing out the changes

If you're just making simple changes to the starter project, testing out the changes is optional. If you want to improve the script, or just get familiar with virtual environments, this is a good idea!

  1. Clone this repo and cd into it
  2. Create a new virtual environment dbt-init-dev and activate it. Make sure your virtual environment uses python 3.
  3. Run pip install -r requirements-dev.txt
  4. You should now have a development version of dbt-init installed. Test your changes by creating a sample project and inspecting the results (I know, we should build real tests), e.g.:
$ dbt-init --client test --target-dir ~/clrcrl/ --warehouse bigquery
New dbt project for test created at /Users/claire/clrcrl/test-dbt! 🎉

$ open /Users/claire/clrcrl/test-dbt

To-do:

  • Configure a new profile as part of init process
