About dbt init command

dbt init helps get you started using dbt Core!

New project​

If this is your first time ever using the tool, it will:

  • ask you to name your project
  • ask you which database adapter you're using (or to Supported Data Platforms)
  • prompt you for each piece of information that dbt needs to connect to that database: things like account, user, password, etc

Then, it will:

  • Create a new folder with your project name and sample files, enough to get you started with dbt
  • Create a connection profile on your local machine. The default location is ~/.dbt/profiles.yml. Read more in configuring your profile.

Existing project​

If you've just cloned or downloaded an existing dbt project, dbt init can still help you set up your connection profile so that you can start working quickly. It will prompt you for connection information, as above, and add a profile (using the profile name from the project) to your local profiles.yml, or create the file if it doesn't already exist.

profile_template.yml​

dbt init knows how to prompt for connection information by looking for a file named profile_template.yml. It will look for this file in two places:

  • Adapter plugin: What's the bare minumum Postgres profile? What's the type of each field, what are its defaults? This information is stored in a file called dbt/include/postgres/profile_template.yml. If you're the maintainer of an adapter plugin, we highly recommend that you add a profile_template.yml to your plugin, too. Refer to the Build, test, document, and promote adapters guide for more information.

  • Existing project: If you're the maintainer of an existing project, and you want to help new users get connected to your database quickly and easily, you can include your own custom profile_template.yml in the root of your project, alongside dbt_project.yml. For common connection attributes, set the values in fixed; leave user-specific attributes in prompts, but with custom hints and defaults as you'd like.
